How to Install CyanogenMod on the Samsung Galaxy Note 3 (Verizon) (hltevzw)

Note: DISCLAIMER

Modifying or replacing your device’s software may void your device’s warranty, lead to data loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk. No one affiliated with the CyanogenMod project is responsible for your actions. Good luck.

Installing a custom recovery

Samsung devices come with a unique boot mode called Download Mode which is very similar to Fastboot Mode on some devices with unlocked bootloaders. Heimdall is a cross-platform, open source tool for interfacing with Download Mode on Samsung devices. The preferred method of installing a custom recovery is through this boot mode. Rooting the stock firmware is neither recommended nor necessary.

  1. Download and install the Heimdall Suite
    • Windows: Extract the Heimdall suite and take note of the directory holding heimdall.exe. You can verify Heimdall is working by opening a command prompt in this directory and typing heimdall version. If you receive an error, be sure that you have the Microsoft Visual C++ 2012 Redistributable Package (x86/32bit) installed on your computer.
    • Linux: Pick the appropriate installation package based on your distribution. The -frontend packages are not required for this guide. After installation, heimdall should be available from the terminal; type heimdall version to verify installation succeeded.
    • Mac: Install the dmg package. After installation, heimdall should be available from the terminal; type heimdall version to verify installation succeeded.
    • Building from source: The source code for the Heimdall Suite is available on Github. For more details about how to compile the Heimdall Suite, please refer to the README file on Github under the relevant operating system directory. You can also refer to the Install and compile Heimdall instructions on this wiki.
  2. Download recovery — you can directly download a recovery image using the link below, or visit TWRP site to check for the latest version of recovery for your device (if your device can be found there). For general info about recoveries click here.
    Recovery: Download
    md5: 2e99b972f2452e4eae946df559d67ba7
  3. Power off the Galaxy Note 3 (Verizon) and connect the USB adapter to the computer but not to the Galaxy Note 3 (Verizon), yet.
  4. Boot the Galaxy Note 3 (Verizon) into download mode. Home & Volume Down & Power Accept the disclaimer on the device. Then, insert the USB cable into the device.
  5. Windows (only) driver installation – Skip this step if you are using Linux or Mac
    A more complete set of the following instructions can be found in the Zadig User Guide.
    1. Run zadig.exe from the Drivers folder of the Heimdall Suite.
    2. Choose Options » List All Devices from the menu.
    3. Select Samsung USB Composite Device or MSM8x60 or Gadget Serial or Device Name from the drop down menu. (If nothing relevant appears, try uninstalling any Samsung related Windows software, like Samsung Windows drivers and/or Kies).
    4. Click Replace Driver (having selecting “Install Driver” from the drop down list built into the button).
    5. If you are prompted with a warning that the installer is unable to verify the publisher of the driver, select Install this driver anyway. You may receive two more prompts about security. Select the options that allow you to carry on.
  6. At this point, familiarize yourself with the Flashing with heimdall notes below so that you are prepared for any strange behaviour if it occurs.
  7. On the computer, open a terminal (or Command Prompt on Windows) in the directory where the recovery image is located and type:
    heimdall flash --RECOVERY recovery.img --no-reboot
    Tip: The file may not be named identically to what’s in this command. If the file is wrapped in a zip or tar file, extract the file first, because heimdall isn’t going to do it for you.
  8. A blue transfer bar will appear on the device showing the recovery being transferred.
  9. Unplug the USB cable from your device.
    • NOTE: Be sure to reboot into recovery immediately after having installed the custom recovery. Otherwise the custom recovery will be overwritten and the device will reboot (appearing as though your custom recovery failed to install).
  10. Manually reboot the phone into recovery mode by performing the following. Home & Volume Up & Power
  11. The Galaxy Note 3 (Verizon) now has a custom recovery installed. Continue to the next section.

Note: Flashing with heimdall

  • In Windows 7 UAC (User Account Control) may need switching off. Once Heimdall is finished it can be re-enabled.
  • Protocol initialization can fail if the device is connected via a USB hub – connect the USB cable directly to the PC
  • It may be necessary to run the heimdall flash command as root in Linux or Mac OS X: sudo heimdall flash [...]. Typical symptoms of this are:
    • a blue bar doesn’t show up after the process has finished
    • Failed to confirm end of file transfer sequence!
  • It may be necessary to capitalize the name of the partition on some devices. Try --KERNEL instead of --kernel and/or --recovery instead of --RECOVERY.
  • If on Linux 64bit you get “unable to execute ./heimdall: No such file or directory”, try the 32bit version and make sure to run it with sudo: reference.
  • On Mac OS X you may see this message: “ERROR: Claiming interface failed!”. If so, you need to disable the default USB drivers with the following commands:
    sudo kextunload -b com.apple.driver.AppleUSBCDC;
    sudo kextunload -b com.apple.driver.AppleUSBCDCACMControl;
    sudo kextunload -b com.apple.driver.AppleUSBCDCACMData;
    If you have installed Samsung Kies, you may further need to unload those USB drivers with the following commands:
    sudo kextunload -b com.devguru.driver.SamsungComposite;
    sudo kextunload -b com.devguru.driver.SamsungACMData
    sudo kextunload -b com.devguru.driver.SamsungACMControl
  • Using Heimdall version 1.4.0 (the latest version available for download on the Glass Echidna website) you may see this message or one similar to it:
    Error: Failed to confirm end of PIT file transfer!
    If you experience this error, follow the instructions for compiling Heimdall from source to get the latest version on GitHub with the issue patched.

Helpful Tip

  • The stock ROM may overwrite your custom recovery on boot. To prevent this, boot immediately into recovery after leaving Download Mode instead of letting the ROM boot up normally. If your recovery is overwritten, simply redo the steps you followed above and catch it before it boots next time.
  • Note for upgrades from gingerbread to jellybean remember the recovery is changed. This means once you install do NOT restore to old-gingerbread-stock ROM from cwm-recovery.
  • To upgrade from stock/CM7/CM9/CM10.1.2/CM10.1.3 to CM10.2, you must first boot into recovery and wipe data, cache, and dalvik cache (factory reset). Due to the new partition layout in CM10.2, failing to perform these steps will result in a bootloop. See here for details; more about repartitioning here. If you missed this step before installing, boot to recovery and factory reset, then reinstall CM10.2.
  • Some users have reported connection errors if the device is connected to a USB hub. If you experience such errors it is recommended that you try connecting your device to a USB port on the motherboard.
  • Antivirus software may prevent Heimdall from connecting properly. Disable your antivirus before proceeding.
  • When Heimdall fails to connect, the Download mode may get stuck, making all further attempts fail too. To retry, you may need to restart the Download mode: turn off the phone by holding Power for 5-10 seconds (or by pulling out the battery), then boot into Download mode and run Heimdall again.
  • If Heimdall fails to connect (errors related to initializing the protocol, or transferring data):
    if you just installed the driver, try rebooting your computer and trying again.
    if you still have troubles after reboot, in Zadig try installing the libusbK driver rather than the WinUSB driver.

Installing CyanogenMod from recovery

  1. Make sure your computer has working adb.
  2. Download the CyanogenMod build package for your device that you’d like to install to your computer.
    Optional: Download 3rd party applications packages, like Google Apps which are necessary to download apps from Google Play.
  3. Place the CyanogenMod .zip package, as well as any optional .zip packages, on the root of /sdcard:
    • Using adb: adb push filename.zip /sdcard/
    Note: You can copy the .zip packages to your device using any method you are familiar with. The adb method is used here because it is universal across all devices and works in both Android and recovery mode. If you are in recovery mode, you may need to ensure /sdcard (sometimes called Internal Storage) is mounted by checking its status in the Mounts menu. If you have booted regularly, USB debugging must be enabled.
  4. If you are not already in recovery, boot to recovery mode now.
    • Home & Volume Up & Power
  5. In Team Win Recovery Project, select menu choices by tapping on the appropriately labelled button.
  6. Optional (Recommended): Select the Backup button to create a backup.
  7. Select Wipe and then Factory Reset.
  8. Select Install.
  9. Navigate to /sdcard and select the CyanogenMod .zip package.
  10. Follow the on-screen notices to install the package.
  11. Optional: Install any additional packages you wish using the same method (if you are installing multiple packages, install CyanogenMod first and then install any subsequent packages on top of it).
  12. Once installation has finished, return to the main menu and select Reboot, then System. The device will now boot into CyanogenMod.

How To Build CyanogenMod For Samsung Galaxy Note 3 (Verizon) (hltevzw)

Introduction

These instructions will hopefully assist you to start with a stock Galaxy Note 3 (Verizon), unlock the bootloader (if necessary), and then download the required tools as well as the very latest source code for CyanogenMod (based on Google’s Android operating system). Using these, you can build both CyanogenMod and CyanogenMod Recovery image from source code, and then install them both to your device.

It is difficult to say how much experience is necessary to follow these instructions. While this guide is certainly not for the very very very uninitiated, these steps shouldn’t require a PhD in software development either. Some readers will have no difficulty and breeze through the steps easily. Others may struggle over the most basic operation. Because people’s experiences, backgrounds, and intuitions differ, it may be a good idea to read through just to ascertain whether you feel comfortable or are getting over your head.

Remember, you assume all risk of trying this, but you will reap the rewards! It’s pretty satisfying to boot into a fresh operating system you baked at home :) And once you’re an Android-building ninja, there will be no more need to wait for “nightly” builds from anyone. You will have at your fingertips the skills to build a full operating system from code to a running device, whenever you want. Where you go from there– maybe you’ll add a feature, fix a bug, add a translation, or use what you’ve learned to build a new app or port to a new device– or maybe you’ll never build again– it’s all really up to you.

What you’ll need

  • A Galaxy Note 3 (Verizon)
  • A relatively recent computer (Linux, OS X, or Windows) with a reasonable amount of RAM and about 100 GB of free storage (more if you enable ccache or build for multiple devices). The less RAM you have, the longer the build will take (aim for 8 GB or more). Using SSDs results in considerably faster build times than traditional hard drives.
  • A USB cable compatible with the Galaxy Note 3 (Verizon) (typically micro USB, but older devices may use mini USB or have a proprietary cable)
  • A decent internet connection & reliable electricity :)
  • Some familiarity with basic Android operation and terminology. It would help if you’ve installed custom roms on other devices and are familiar with recovery. It may also be useful to know some basic command line concepts such as cd for “change directory”, the concept of directory hierarchies, that in Linux they are separated by /, etc.

If you are not accustomed to using Linux– this is an excellent chance to learn. It’s free– just download and run a virtual machine (VM) such as Virtualbox, then install a Linux distribution such as Ubuntu (AOSP vets Ubuntu as well). Any recent 64-bit version should work great, but the latest is recommended.

Note:

You want to use a 64-bit version of Linux. A 32-bit Linux environment will only work if you are building CyanogenMod 6 and older. For CyanogenMod 10.1, if you encounter issues with 64bit host binaries, you can set BUILD_HOST_32bit=1 in your environment. This is generally not needed, though, especially with CyanogenMod 10.2 and newer.

Using a VM allows Linux to run as a guest inside your host computer– a computer in a computer, if you will. If you hate Linux for whatever reason, you can always just uninstall and delete the whole thing. (There are plenty of places to find instructions for setting up Virtualbox with Ubuntu, so I’ll leave it to you to do that.)

So let’s begin!

Build CyanogenMod and CyanogenMod Recovery

Prepare the Build Environment

Note:

You only need to do these steps the first time you build. If you previously prepared your build environment and have downloaded the CyanogenMod source code for another device, skip to Prepare the device-specific code.

Install the SDK

If you have not previously installed adb and fastboot, install the Android SDK. “SDK” stands for Software Developer Kit, and it includes useful tools that you can use to flash software, look at the system logs in real time, grab screenshots, and more– all from your computer.

Helpful Tip

While the SDK contains lots of different things– the two tools you are most interested in for building Android are adb and fastboot, located in the /platform-tools directory.

Install the Build Packages

Several “build packages” are needed to build CyanogenMod. You can install these using the package manager of your choice.

Helpful Tip

A package manager in Linux is a system used to install or remove software (usually originating from the Internet) on your computer. With Ubuntu, you can use the Ubuntu Software Center. Even better, you may also use the apt-get install command directly in the Terminal. (Learn more about the apt packaging tool system from Wikipedia.)

For both 32-bit & 64-bit systems, you’ll need: 

bc bison build-essential curl flex git gnupg gperf libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libwxgtk2.8-dev libxml2 libxml2-utils lzop maven openjdk-7-jdk pngcrush schedtool squashfs-tools xsltproc zip zlib1g-dev

In addition to the above, for 64-bit systems, get these: 

g++-multilib gcc-multilib lib32ncurses5-dev lib32readline-gplv2-dev lib32z1-dev

For Ubuntu 15.10 (wily) and newer, substitute:

  • lib32readline-gplv2-dev → lib32readline6-dev

For Ubuntu 16.04 (xenial) and newer, substitute (additionally see java notes below):

  • libwxgtk2.8-dev → libwxgtk3.0-dev
  • openjdk-7-jdk → openjdk-8-jdk

Java versions: Different versions of CyanogenMod require different versions of the JDK (Java Development Kit):

  • CyanogenMod 7 – 9: Sun/Oracle Java SE 1.6
  • CyanogenMod 10.1: Sun/Oracle Java SE 1.6 or 1.7
  • CyanogenMod 10.2 – 11.0: Sun/Oracle Java SE 1.6 or 1.7 (OpenJDK 1.7 works fine, but the build system will display a warning)
  • CyanogenMod 12.0 – 13.0: OpenJDK 1.7 (see note about OpenJDK 1.8 below)
  • CyanogenMod 14.1: OpenJDK 1.8

Ubuntu 16.04 (Xenial Xerus) or newer and OpenJDK: Since OpenJDK 1.7 was removed from the official Ubuntu repositories, you have a couple options:

  1. Obtain OpenJDK 1.7 from the openjdk-r PPA
  2. Enable experimental OpenJDK 1.8 support in CyanogenMod 13.0 (not available in earlier version). To enable OpenJDK 1.8 support, add this line to your $HOME/.bashrc file: export EXPERIMENTAL_USE_JAVA8=true.

Also see http://source.android.com/source/initializing.html which lists needed packages.

Create the directories

You will need to set up some directories in your build environment.

To create them: 

$ mkdir -p ~/bin
$ mkdir -p ~/android/system

Install the repo command

Enter the following to download the “repo” binary and make it executable (runnable): 

$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

Put the ~/bin directory in your path of execution

In recent versions of Ubuntu, ~/bin should already be in your PATH. You can check this by opening ~/.profile with a text editor and verifying the following code exists (add it if it is missing): 

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

Initialize the CyanogenMod source repository

Enter the following to initialize the repository:

Note: Make sure the cm branch entered here is the one you wish to build and is supported on your device.
$ cd ~/android/system/
$ repo init -u https://github.com/CyanogenMod/android.git -b cm-13.0

Download the source code

To start the download of all the source code to your computer: 

$ repo sync

The CM manifests include a sensible default configuration for repo, which we strongly suggest you use (i.e. don’t add any options to sync). For reference, our default values are -j 4 and -c. The -j 4 part means that there will be four simultaneous threads/connections. If you experience problems syncing, you can lower this to -j 3 or -j 2. -c will ask repo to pull in only the current branch, instead of the entire CM history.

Prepare to wait a long time while the source code downloads.

Helpful Tip

The repo sync command is used to update the latest source code from CyanogenMod and Google. Remember it, as you can do it every few days to keep your code base fresh and up-to-date.

Get prebuilt apps (CM11 and below)

Next, 

$ cd ~/android/system/vendor/cm

then enter: 

$ ./get-prebuilts

You won’t see any confirmation- just another prompt. But this should cause some prebuilt apps to be loaded and installed into the source code. Once completed, this does not need to be done again.

Prepare the device-specific code

Helpful Tip – Errors during breakfast

Different maintainers setup their device inheritance rules differently. Some require a vendor directory to be populated before breakfast will even succeed. If you receive an error here about vendor makefiles, then jump down to the next section Extract proprietary blobs. The first portion of breakfast should have succeeded at pulling in the device tree and the extract blobs script should be available. After completing that section, you can rerun breakfast hltevzw

After the source downloads, ensure you are in the root of the source code (cd ~/android/system), then type: 

$ source build/envsetup.sh
$ breakfast hltevzw

This will download the device specific configuration and kernel source for your device. An alternative to using the breakfast command is to build your own local manifest. To do this, you will need to locate your device on CyanogenMod’s GitHub and list all of the repositories defined in cm.dependencies in your local manifest.

Helpful Tip

If you want to know more about what source build/envsetup.sh does or simply want to know more about the breakfast, brunch and lunch commands, you can head over to the Envsetup help page.

Helpful Tip

Instead of typing cd ~/android/system every time you want to return back to the root of the source code, here’s a short command that will do it for you: croot. To use this command, you must first run source build/envsetup.sh from ~/android/system.

Extract proprietary blobs

Now ensure that your Galaxy Note 3 (Verizon) is connected to your computer via the USB cable and that you are in the ~/android/system/device/samsung/hltevzw directory (you can cd ~/android/system/device/samsung/hltevzw if necessary). Then run the extract-files.sh script: 

$ ./extract-files.sh

You should see the proprietary files (aka “blobs”) get pulled from the device and moved to the ~/android/system/vendor/samsung directory. If you see errors about adb being unable to pull the files, adb may not be in the path of execution. If this is the case, see the adb page for suggestions for dealing with “command not found” errors.

Note:

Your device should already be running a build of CyanogenMod for the branch you wish to build for the extract-files.sh script to function properly.

Note:

It’s important that these proprietary files are extracted to the ~/android/system/vendor/samsung directory by using the extract-files.sh script. Makefiles are generated at the same time to make sure the blobs are eventually copied to the device. Without these blobs, CyanogenMod may build without error, but you’ll be missing important functionality, such as graphics libraries that enable you to see anything!

Turn on caching to speed up build

You can speed up subsequent builds by adding 

export USE_CCACHE=1

to your ~/.bashrc file (what’s a .bashrc file?). Then, specify the amount of disk space to dedicate to ccache by typing this from the top of your Android tree: 

prebuilts/misc/linux-x86/ccache/ccache -M 50G

where 50G corresponds to 50GB of cache. This only needs to be run once and the setting will be remembered. Anywhere in the range of 25GB to 100GB will result in very noticeably increased build speeds (for instance, a typical 1hr build time can be reduced to 20min). If you’re only building for one device, 25GB-50GB is fine. If you plan to build for several devices that do not share the same kernel source, aim for 75GB-100GB. This space will be permanently occupied on your drive, so take this into consideration. See more information about ccache on Google’s android build environment initialization page.

Helpful Tip

If you are a very active developer, working on many other projects than just Android, you might prefer to keep your Android ccache independent (because it’s huge and can slow down the efficiency of ccache in your other projects). Beginning with CyanogenMod 12.1, you can specify environment variables for the location and size of CyanogenMod’s ccache. Some syntax examples: export ANDROID_CCACHE_DIR="$HOME/android/.ccache" and export ANDROID_CCACHE_SIZE="50G".

Start the build

Time to start building! So now type: 

$ croot
$ brunch hltevzw

The build should begin.

Helpful Tip

If the build doesn’t start, try lunch and choose your device from the menu. If that doesn’t work, try breakfast and choose from the menu. The command make hltevzw should then work.

Helpful Tip

A second, bonus tip! If you get a command not found error for croot, brunch, or lunch, be sure you’ve done the source build/envsetup.sh command in this Terminal session from the ~/android/system directory.

Helpful Tip

A third tip! If the build to fails while downloading Gello, you’ll need to import a missing certificate into Maven’s truststore. Detailed instructions on how to do that can be found here

If the build breaks…

  • If you experience this not-enough-memory-related error…
ERROR: signapk.jar failed: return code 1make: *** [out/target/product/hltevzw/cm_hltevzw-ota-eng.root.zip] Error 1

…you may want to make the following change to ~/android/system/build/tools/releasetools/common.py:

Search for instances of -Xmx2048m (it should appear either under OPTIONS.java_args or near usage of signapk.jar), and replace it with -Xmx1024m or -Xmx512m.

Then start the build again (with brunch).

  • If you see a message about things suddenly being “killed” for no reason, your (virtual) machine may have run out of memory or storage space. Assign it more resources and try again.

Install the build

Assuming the build completed without error (it will be obvious when it finishes), type: 

$ cd $OUT

in the same terminal window that you did the build. Here you’ll find all the files that were created. The stuff that will go in /system is in a folder called system. The stuff that will become your ramdisk is in a folder called root. And your kernel is called… kernel.

But that’s all just background info. The two files we are interested in are (1) recovery.img, which contains CyanogenMod Recovery, and (2) cm-13.0-20161224-UNOFFICIAL-hltevzw.zip, which is the CyanogenMod installation package.

Install CyanogenMod

Back to the $OUT directory on your computer– you should see a file that looks something like: 

cm-13.0-20161224-UNOFFICIAL-hltevzw.zip

Note:

The above file name may vary depending on the version of CM you are building. Your build may not include a version number or may identify itself as a “KANG” rather than UNOFFICIAL version. Regardless, the file name will end in .zip and should be titled similarly to official builds.

Now you can flash the cm...zip file above as usual via recovery mode. Before doing so, now is a good time to make a backup of whatever installation is currently running on the device in case something goes wrong with the flash attempt. While CyanogenMod Recovery doesn’t have a backup feature, there are other custom recoveries available that do. You can also use something like Titanium Backup (root required) as an alternative.

Success! So….what’s next?

You’ve done it! Welcome to the elite club of self-builders. You’ve built your operating system from scratch, from the ground up. You are the master/mistress of your domain… and hopefully you’ve learned a bit on the way and had some fun too.

Now that you’ve succeeded in building CyanogenMod for your device, here are some suggestions on what to do next.

Also, be sure to take a glance at the Dev Center on this wiki for all kinds of more detailed information about developer topics ranging from collecting logs, understanding what’s in the source code directories, submitting your own contributions, porting CyanogenMod to new devices, and a lot more.

Congrats again!

How to Install CyanogenMod on the Samsung Galaxy Note 3 (T-Mobile) (hltetmo)

Note: DISCLAIMER

Modifying or replacing your device’s software may void your device’s warranty, lead to data loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk. No one affiliated with the CyanogenMod project is responsible for your actions. Good luck.

Installing a custom recovery

Samsung devices come with a unique boot mode called Download Mode which is very similar to Fastboot Mode on some devices with unlocked bootloaders. Heimdall is a cross-platform, open source tool for interfacing with Download Mode on Samsung devices. The preferred method of installing a custom recovery is through this boot mode. Rooting the stock firmware is neither recommended nor necessary.

  1. Download and install the Heimdall Suite
    • Windows: Extract the Heimdall suite and take note of the directory holding heimdall.exe. You can verify Heimdall is working by opening a command prompt in this directory and typing heimdall version. If you receive an error, be sure that you have the Microsoft Visual C++ 2012 Redistributable Package (x86/32bit) installed on your computer.
    • Linux: Pick the appropriate installation package based on your distribution. The -frontend packages are not required for this guide. After installation, heimdall should be available from the terminal; type heimdall version to verify installation succeeded.
    • Mac: Install the dmg package. After installation, heimdall should be available from the terminal; type heimdall version to verify installation succeeded.
    • Building from source: The source code for the Heimdall Suite is available on Github. For more details about how to compile the Heimdall Suite, please refer to the README file on Github under the relevant operating system directory. You can also refer to the Install and compile Heimdall instructions on this wiki.
  2. Download recovery — you can directly download a recovery image using the link below, or visit TWRP site to check for the latest version of recovery for your device (if your device can be found there). For general info about recoveries click here.
    Recovery: Download
    md5: 9d4e2927d0cd2882695916feec2bb1da
  3. Power off the Galaxy Note 3 (T-Mobile) and connect the USB adapter to the computer but not to the Galaxy Note 3 (T-Mobile), yet.
  4. Boot the Galaxy Note 3 (T-Mobile) into download mode. Home & Volume Down & Power Accept the disclaimer on the device. Then, insert the USB cable into the device.
  5. Windows (only) driver installation – Skip this step if you are using Linux or Mac
    A more complete set of the following instructions can be found in the Zadig User Guide.
    1. Run zadig.exe from the Drivers folder of the Heimdall Suite.
    2. Choose Options » List All Devices from the menu.
    3. Select Samsung USB Composite Device or MSM8x60 or Gadget Serial or Device Name from the drop down menu. (If nothing relevant appears, try uninstalling any Samsung related Windows software, like Samsung Windows drivers and/or Kies).
    4. Click Replace Driver (having selecting “Install Driver” from the drop down list built into the button).
    5. If you are prompted with a warning that the installer is unable to verify the publisher of the driver, select Install this driver anyway. You may receive two more prompts about security. Select the options that allow you to carry on.
  6. At this point, familiarize yourself with the Flashing with heimdall notes below so that you are prepared for any strange behaviour if it occurs.
  7. On the computer, open a terminal (or Command Prompt on Windows) in the directory where the recovery image is located and type:
    heimdall flash --RECOVERY recovery.img --no-reboot
    Tip: The file may not be named identically to what’s in this command. If the file is wrapped in a zip or tar file, extract the file first, because heimdall isn’t going to do it for you.
  8. A blue transfer bar will appear on the device showing the recovery being transferred.
  9. Unplug the USB cable from your device.
    • NOTE: Be sure to reboot into recovery immediately after having installed the custom recovery. Otherwise the custom recovery will be overwritten and the device will reboot (appearing as though your custom recovery failed to install).
  10. Manually reboot the phone into recovery mode by performing the following. Home & Volume Up & Power
  11. The Galaxy Note 3 (T-Mobile) now has a custom recovery installed. Continue to the next section.

Note: Flashing with heimdall

  • In Windows 7 UAC (User Account Control) may need switching off. Once Heimdall is finished it can be re-enabled.
  • Protocol initialization can fail if the device is connected via a USB hub – connect the USB cable directly to the PC
  • It may be necessary to run the heimdall flash command as root in Linux or Mac OS X: sudo heimdall flash [...]. Typical symptoms of this are:
    • a blue bar doesn’t show up after the process has finished
    • Failed to confirm end of file transfer sequence!
  • It may be necessary to capitalize the name of the partition on some devices. Try --KERNEL instead of --kernel and/or --recovery instead of --RECOVERY.
  • If on Linux 64bit you get “unable to execute ./heimdall: No such file or directory”, try the 32bit version and make sure to run it with sudo: reference.
  • On Mac OS X you may see this message: “ERROR: Claiming interface failed!”. If so, you need to disable the default USB drivers with the following commands:
    sudo kextunload -b com.apple.driver.AppleUSBCDC;
    sudo kextunload -b com.apple.driver.AppleUSBCDCACMControl;
    sudo kextunload -b com.apple.driver.AppleUSBCDCACMData;
    If you have installed Samsung Kies, you may further need to unload those USB drivers with the following commands:
    sudo kextunload -b com.devguru.driver.SamsungComposite;
    sudo kextunload -b com.devguru.driver.SamsungACMData
    sudo kextunload -b com.devguru.driver.SamsungACMControl
  • Using Heimdall version 1.4.0 (the latest version available for download on the Glass Echidna website) you may see this message or one similar to it:
    Error: Failed to confirm end of PIT file transfer!
    If you experience this error, follow the instructions for compiling Heimdall from source to get the latest version on GitHub with the issue patched.

Helpful Tip

  • The stock ROM may overwrite your custom recovery on boot. To prevent this, boot immediately into recovery after leaving Download Mode instead of letting the ROM boot up normally. If your recovery is overwritten, simply redo the steps you followed above and catch it before it boots next time.
  • Note for upgrades from gingerbread to jellybean remember the recovery is changed. This means once you install do NOT restore to old-gingerbread-stock ROM from cwm-recovery.
  • To upgrade from stock/CM7/CM9/CM10.1.2/CM10.1.3 to CM10.2, you must first boot into recovery and wipe data, cache, and dalvik cache (factory reset). Due to the new partition layout in CM10.2, failing to perform these steps will result in a bootloop. See here for details; more about repartitioning here. If you missed this step before installing, boot to recovery and factory reset, then reinstall CM10.2.
  • Some users have reported connection errors if the device is connected to a USB hub. If you experience such errors it is recommended that you try connecting your device to a USB port on the motherboard.
  • Antivirus software may prevent Heimdall from connecting properly. Disable your antivirus before proceeding.
  • When Heimdall fails to connect, the Download mode may get stuck, making all further attempts fail too. To retry, you may need to restart the Download mode: turn off the phone by holding Power for 5-10 seconds (or by pulling out the battery), then boot into Download mode and run Heimdall again.
  • If Heimdall fails to connect (errors related to initializing the protocol, or transferring data):
    if you just installed the driver, try rebooting your computer and trying again.
    if you still have troubles after reboot, in Zadig try installing the libusbK driver rather than the WinUSB driver.

Installing CyanogenMod from recovery

  1. Make sure your computer has working adb.
  2. Download the CyanogenMod build package for your device that you’d like to install to your computer.
    Optional: Download 3rd party applications packages, like Google Apps which are necessary to download apps from Google Play.
  3. Place the CyanogenMod .zip package, as well as any optional .zip packages, on the root of /sdcard:
    • Using adb: adb push filename.zip /sdcard/
    Note: You can copy the .zip packages to your device using any method you are familiar with. The adb method is used here because it is universal across all devices and works in both Android and recovery mode. If you are in recovery mode, you may need to ensure /sdcard (sometimes called Internal Storage) is mounted by checking its status in the Mounts menu. If you have booted regularly, USB debugging must be enabled.
  4. If you are not already in recovery, boot to recovery mode now.
    • Home & Volume Up & Power
  5. In Team Win Recovery Project, select menu choices by tapping on the appropriately labelled button.
  6. Optional (Recommended): Select the Backup button to create a backup.
  7. Select Wipe and then Factory Reset.
  8. Select Install.
  9. Navigate to /sdcard and select the CyanogenMod .zip package.
  10. Follow the on-screen notices to install the package.
  11. Optional: Install any additional packages you wish using the same method (if you are installing multiple packages, install CyanogenMod first and then install any subsequent packages on top of it).
  12. Once installation has finished, return to the main menu and select Reboot, then System. The device will now boot into CyanogenMod.

How To Build CyanogenMod For Samsung Galaxy Note 3 (T-Mobile) (hltetmo)

Introduction

These instructions will hopefully assist you to start with a stock Galaxy Note 3 (T-Mobile), unlock the bootloader (if necessary), and then download the required tools as well as the very latest source code for CyanogenMod (based on Google’s Android operating system). Using these, you can build both CyanogenMod and CyanogenMod Recovery image from source code, and then install them both to your device.

It is difficult to say how much experience is necessary to follow these instructions. While this guide is certainly not for the very very very uninitiated, these steps shouldn’t require a PhD in software development either. Some readers will have no difficulty and breeze through the steps easily. Others may struggle over the most basic operation. Because people’s experiences, backgrounds, and intuitions differ, it may be a good idea to read through just to ascertain whether you feel comfortable or are getting over your head.

Remember, you assume all risk of trying this, but you will reap the rewards! It’s pretty satisfying to boot into a fresh operating system you baked at home :) And once you’re an Android-building ninja, there will be no more need to wait for “nightly” builds from anyone. You will have at your fingertips the skills to build a full operating system from code to a running device, whenever you want. Where you go from there– maybe you’ll add a feature, fix a bug, add a translation, or use what you’ve learned to build a new app or port to a new device– or maybe you’ll never build again– it’s all really up to you.

What you’ll need

  • A Galaxy Note 3 (T-Mobile)
  • A relatively recent computer (Linux, OS X, or Windows) with a reasonable amount of RAM and about 100 GB of free storage (more if you enable ccache or build for multiple devices). The less RAM you have, the longer the build will take (aim for 8 GB or more). Using SSDs results in considerably faster build times than traditional hard drives.
  • A USB cable compatible with the Galaxy Note 3 (T-Mobile) (typically micro USB, but older devices may use mini USB or have a proprietary cable)
  • A decent internet connection & reliable electricity :)
  • Some familiarity with basic Android operation and terminology. It would help if you’ve installed custom roms on other devices and are familiar with recovery. It may also be useful to know some basic command line concepts such as cd for “change directory”, the concept of directory hierarchies, that in Linux they are separated by /, etc.

If you are not accustomed to using Linux– this is an excellent chance to learn. It’s free– just download and run a virtual machine (VM) such as Virtualbox, then install a Linux distribution such as Ubuntu (AOSP vets Ubuntu as well). Any recent 64-bit version should work great, but the latest is recommended.

Note:

You want to use a 64-bit version of Linux. A 32-bit Linux environment will only work if you are building CyanogenMod 6 and older. For CyanogenMod 10.1, if you encounter issues with 64bit host binaries, you can set BUILD_HOST_32bit=1 in your environment. This is generally not needed, though, especially with CyanogenMod 10.2 and newer.

Using a VM allows Linux to run as a guest inside your host computer– a computer in a computer, if you will. If you hate Linux for whatever reason, you can always just uninstall and delete the whole thing. (There are plenty of places to find instructions for setting up Virtualbox with Ubuntu, so I’ll leave it to you to do that.)

So let’s begin!

Build CyanogenMod and CyanogenMod Recovery

Prepare the Build Environment

Note:

You only need to do these steps the first time you build. If you previously prepared your build environment and have downloaded the CyanogenMod source code for another device, skip to Prepare the device-specific code.

Install the SDK

If you have not previously installed adb and fastboot, install the Android SDK. “SDK” stands for Software Developer Kit, and it includes useful tools that you can use to flash software, look at the system logs in real time, grab screenshots, and more– all from your computer.

Helpful Tip

While the SDK contains lots of different things– the two tools you are most interested in for building Android are adb and fastboot, located in the /platform-tools directory.

Install the Build Packages

Several “build packages” are needed to build CyanogenMod. You can install these using the package manager of your choice.

Helpful Tip

A package manager in Linux is a system used to install or remove software (usually originating from the Internet) on your computer. With Ubuntu, you can use the Ubuntu Software Center. Even better, you may also use the apt-get install command directly in the Terminal. (Learn more about the apt packaging tool system from Wikipedia.)

For both 32-bit & 64-bit systems, you’ll need: 

bc bison build-essential curl flex git gnupg gperf libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libwxgtk2.8-dev libxml2 libxml2-utils lzop maven openjdk-7-jdk pngcrush schedtool squashfs-tools xsltproc zip zlib1g-dev

In addition to the above, for 64-bit systems, get these: 

g++-multilib gcc-multilib lib32ncurses5-dev lib32readline-gplv2-dev lib32z1-dev

For Ubuntu 15.10 (wily) and newer, substitute:

  • lib32readline-gplv2-dev → lib32readline6-dev

For Ubuntu 16.04 (xenial) and newer, substitute (additionally see java notes below):

  • libwxgtk2.8-dev → libwxgtk3.0-dev
  • openjdk-7-jdk → openjdk-8-jdk

Java versions: Different versions of CyanogenMod require different versions of the JDK (Java Development Kit):

  • CyanogenMod 7 – 9: Sun/Oracle Java SE 1.6
  • CyanogenMod 10.1: Sun/Oracle Java SE 1.6 or 1.7
  • CyanogenMod 10.2 – 11.0: Sun/Oracle Java SE 1.6 or 1.7 (OpenJDK 1.7 works fine, but the build system will display a warning)
  • CyanogenMod 12.0 – 13.0: OpenJDK 1.7 (see note about OpenJDK 1.8 below)
  • CyanogenMod 14.1: OpenJDK 1.8

Ubuntu 16.04 (Xenial Xerus) or newer and OpenJDK: Since OpenJDK 1.7 was removed from the official Ubuntu repositories, you have a couple options:

  1. Obtain OpenJDK 1.7 from the openjdk-r PPA
  2. Enable experimental OpenJDK 1.8 support in CyanogenMod 13.0 (not available in earlier version). To enable OpenJDK 1.8 support, add this line to your $HOME/.bashrc file: export EXPERIMENTAL_USE_JAVA8=true.

Also see http://source.android.com/source/initializing.html which lists needed packages.

Create the directories

You will need to set up some directories in your build environment.

To create them: 

$ mkdir -p ~/bin
$ mkdir -p ~/android/system

Install the repo command

Enter the following to download the “repo” binary and make it executable (runnable): 

$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

Put the ~/bin directory in your path of execution

In recent versions of Ubuntu, ~/bin should already be in your PATH. You can check this by opening ~/.profile with a text editor and verifying the following code exists (add it if it is missing): 

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

Initialize the CyanogenMod source repository

Enter the following to initialize the repository:

Note: Make sure the cm branch entered here is the one you wish to build and is supported on your device.
$ cd ~/android/system/
$ repo init -u https://github.com/CyanogenMod/android.git -b cm-13.0

Download the source code

To start the download of all the source code to your computer: 

$ repo sync

The CM manifests include a sensible default configuration for repo, which we strongly suggest you use (i.e. don’t add any options to sync). For reference, our default values are -j 4 and -c. The -j 4 part means that there will be four simultaneous threads/connections. If you experience problems syncing, you can lower this to -j 3 or -j 2. -c will ask repo to pull in only the current branch, instead of the entire CM history.

Prepare to wait a long time while the source code downloads.

Helpful Tip

The repo sync command is used to update the latest source code from CyanogenMod and Google. Remember it, as you can do it every few days to keep your code base fresh and up-to-date.

Get prebuilt apps (CM11 and below)

Next, 

$ cd ~/android/system/vendor/cm

then enter: 

$ ./get-prebuilts

You won’t see any confirmation- just another prompt. But this should cause some prebuilt apps to be loaded and installed into the source code. Once completed, this does not need to be done again.

Prepare the device-specific code

Helpful Tip – Errors during breakfast

Different maintainers setup their device inheritance rules differently. Some require a vendor directory to be populated before breakfast will even succeed. If you receive an error here about vendor makefiles, then jump down to the next section Extract proprietary blobs. The first portion of breakfast should have succeeded at pulling in the device tree and the extract blobs script should be available. After completing that section, you can rerun breakfast hltetmo

After the source downloads, ensure you are in the root of the source code (cd ~/android/system), then type: 

$ source build/envsetup.sh
$ breakfast hltetmo

This will download the device specific configuration and kernel source for your device. An alternative to using the breakfast command is to build your own local manifest. To do this, you will need to locate your device on CyanogenMod’s GitHub and list all of the repositories defined in cm.dependencies in your local manifest.

Helpful Tip

If you want to know more about what source build/envsetup.sh does or simply want to know more about the breakfast, brunch and lunch commands, you can head over to the Envsetup help page.

Helpful Tip

Instead of typing cd ~/android/system every time you want to return back to the root of the source code, here’s a short command that will do it for you: croot. To use this command, you must first run source build/envsetup.sh from ~/android/system.

Extract proprietary blobs

Now ensure that your Galaxy Note 3 (T-Mobile) is connected to your computer via the USB cable and that you are in the ~/android/system/device/samsung/hltetmo directory (you can cd ~/android/system/device/samsung/hltetmo if necessary). Then run the extract-files.sh script: 

$ ./extract-files.sh

You should see the proprietary files (aka “blobs”) get pulled from the device and moved to the ~/android/system/vendor/samsung directory. If you see errors about adb being unable to pull the files, adb may not be in the path of execution. If this is the case, see the adb page for suggestions for dealing with “command not found” errors.

Note:

Your device should already be running a build of CyanogenMod for the branch you wish to build for the extract-files.sh script to function properly.

Note:

It’s important that these proprietary files are extracted to the ~/android/system/vendor/samsung directory by using the extract-files.sh script. Makefiles are generated at the same time to make sure the blobs are eventually copied to the device. Without these blobs, CyanogenMod may build without error, but you’ll be missing important functionality, such as graphics libraries that enable you to see anything!

Turn on caching to speed up build

You can speed up subsequent builds by adding 

export USE_CCACHE=1

to your ~/.bashrc file (what’s a .bashrc file?). Then, specify the amount of disk space to dedicate to ccache by typing this from the top of your Android tree: 

prebuilts/misc/linux-x86/ccache/ccache -M 50G

where 50G corresponds to 50GB of cache. This only needs to be run once and the setting will be remembered. Anywhere in the range of 25GB to 100GB will result in very noticeably increased build speeds (for instance, a typical 1hr build time can be reduced to 20min). If you’re only building for one device, 25GB-50GB is fine. If you plan to build for several devices that do not share the same kernel source, aim for 75GB-100GB. This space will be permanently occupied on your drive, so take this into consideration. See more information about ccache on Google’s android build environment initialization page.

Helpful Tip

If you are a very active developer, working on many other projects than just Android, you might prefer to keep your Android ccache independent (because it’s huge and can slow down the efficiency of ccache in your other projects). Beginning with CyanogenMod 12.1, you can specify environment variables for the location and size of CyanogenMod’s ccache. Some syntax examples: export ANDROID_CCACHE_DIR="$HOME/android/.ccache" and export ANDROID_CCACHE_SIZE="50G".

Start the build

Time to start building! So now type: 

$ croot
$ brunch hltetmo

The build should begin.

Helpful Tip

If the build doesn’t start, try lunch and choose your device from the menu. If that doesn’t work, try breakfast and choose from the menu. The command make hltetmo should then work.

Helpful Tip

A second, bonus tip! If you get a command not found error for croot, brunch, or lunch, be sure you’ve done the source build/envsetup.sh command in this Terminal session from the ~/android/system directory.

Helpful Tip

A third tip! If the build to fails while downloading Gello, you’ll need to import a missing certificate into Maven’s truststore. Detailed instructions on how to do that can be found here

If the build breaks…

  • If you experience this not-enough-memory-related error…
ERROR: signapk.jar failed: return code 1make: *** [out/target/product/hltetmo/cm_hltetmo-ota-eng.root.zip] Error 1

…you may want to make the following change to ~/android/system/build/tools/releasetools/common.py:

Search for instances of -Xmx2048m (it should appear either under OPTIONS.java_args or near usage of signapk.jar), and replace it with -Xmx1024m or -Xmx512m.

Then start the build again (with brunch).

  • If you see a message about things suddenly being “killed” for no reason, your (virtual) machine may have run out of memory or storage space. Assign it more resources and try again.

Install the build

Assuming the build completed without error (it will be obvious when it finishes), type: 

$ cd $OUT

in the same terminal window that you did the build. Here you’ll find all the files that were created. The stuff that will go in /system is in a folder called system. The stuff that will become your ramdisk is in a folder called root. And your kernel is called… kernel.

But that’s all just background info. The two files we are interested in are (1) recovery.img, which contains CyanogenMod Recovery, and (2) cm-13.0-20161224-UNOFFICIAL-hltetmo.zip, which is the CyanogenMod installation package.

Install CyanogenMod

Back to the $OUT directory on your computer– you should see a file that looks something like: 

cm-13.0-20161224-UNOFFICIAL-hltetmo.zip

Note:

The above file name may vary depending on the version of CM you are building. Your build may not include a version number or may identify itself as a “KANG” rather than UNOFFICIAL version. Regardless, the file name will end in .zip and should be titled similarly to official builds.

Now you can flash the cm...zip file above as usual via recovery mode. Before doing so, now is a good time to make a backup of whatever installation is currently running on the device in case something goes wrong with the flash attempt. While CyanogenMod Recovery doesn’t have a backup feature, there are other custom recoveries available that do. You can also use something like Titanium Backup (root required) as an alternative.

Success! So….what’s next?

You’ve done it! Welcome to the elite club of self-builders. You’ve built your operating system from scratch, from the ground up. You are the master/mistress of your domain… and hopefully you’ve learned a bit on the way and had some fun too.

Now that you’ve succeeded in building CyanogenMod for your device, here are some suggestions on what to do next.

Also, be sure to take a glance at the Dev Center on this wiki for all kinds of more detailed information about developer topics ranging from collecting logs, understanding what’s in the source code directories, submitting your own contributions, porting CyanogenMod to new devices, and a lot more.

Congrats again!

How to Install CyanogenMod on the Samsung Galaxy Note 3 (Sprint) (hltespr)

Note: DISCLAIMER

Modifying or replacing your device’s software may void your device’s warranty, lead to data loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk. No one affiliated with the CyanogenMod project is responsible for your actions. Good luck.

Installing a custom recovery

Samsung devices come with a unique boot mode called Download Mode which is very similar to Fastboot Mode on some devices with unlocked bootloaders. Heimdall is a cross-platform, open source tool for interfacing with Download Mode on Samsung devices. The preferred method of installing a custom recovery is through this boot mode. Rooting the stock firmware is neither recommended nor necessary.

  1. Download and install the Heimdall Suite
    • Windows: Extract the Heimdall suite and take note of the directory holding heimdall.exe. You can verify Heimdall is working by opening a command prompt in this directory and typing heimdall version. If you receive an error, be sure that you have the Microsoft Visual C++ 2012 Redistributable Package (x86/32bit) installed on your computer.
    • Linux: Pick the appropriate installation package based on your distribution. The -frontend packages are not required for this guide. After installation, heimdall should be available from the terminal; type heimdall version to verify installation succeeded.
    • Mac: Install the dmg package. After installation, heimdall should be available from the terminal; type heimdall version to verify installation succeeded.
    • Building from source: The source code for the Heimdall Suite is available on Github. For more details about how to compile the Heimdall Suite, please refer to the README file on Github under the relevant operating system directory. You can also refer to the Install and compile Heimdall instructions on this wiki.
  2. Download recovery — you can directly download a recovery image using the link below, or visit TWRP site to check for the latest version of recovery for your device (if your device can be found there). For general info about recoveries click here.
    Recovery: Download
    md5: a95ef980ef5594847bc881fc60423cab
  3. Power off the Galaxy Note 3 (Sprint) and connect the USB adapter to the computer but not to the Galaxy Note 3 (Sprint), yet.
  4. Boot the Galaxy Note 3 (Sprint) into download mode. Home & Volume Down & Power Accept the disclaimer on the device. Then, insert the USB cable into the device.
  5. Windows (only) driver installation – Skip this step if you are using Linux or Mac
    A more complete set of the following instructions can be found in the Zadig User Guide.
    1. Run zadig.exe from the Drivers folder of the Heimdall Suite.
    2. Choose Options » List All Devices from the menu.
    3. Select Samsung USB Composite Device or MSM8x60 or Gadget Serial or Device Name from the drop down menu. (If nothing relevant appears, try uninstalling any Samsung related Windows software, like Samsung Windows drivers and/or Kies).
    4. Click Replace Driver (having selecting “Install Driver” from the drop down list built into the button).
    5. If you are prompted with a warning that the installer is unable to verify the publisher of the driver, select Install this driver anyway. You may receive two more prompts about security. Select the options that allow you to carry on.
  6. At this point, familiarize yourself with the Flashing with heimdall notes below so that you are prepared for any strange behaviour if it occurs.
  7. On the computer, open a terminal (or Command Prompt on Windows) in the directory where the recovery image is located and type:
    heimdall flash --RECOVERY recovery.img --no-reboot
    Tip: The file may not be named identically to what’s in this command. If the file is wrapped in a zip or tar file, extract the file first, because heimdall isn’t going to do it for you.
  8. A blue transfer bar will appear on the device showing the recovery being transferred.
  9. Unplug the USB cable from your device.
    • NOTE: Be sure to reboot into recovery immediately after having installed the custom recovery. Otherwise the custom recovery will be overwritten and the device will reboot (appearing as though your custom recovery failed to install).
  10. Manually reboot the phone into recovery mode by performing the following. Home & Volume Up & Power
  11. The Galaxy Note 3 (Sprint) now has a custom recovery installed. Continue to the next section.

Note: Flashing with heimdall

  • In Windows 7 UAC (User Account Control) may need switching off. Once Heimdall is finished it can be re-enabled.
  • Protocol initialization can fail if the device is connected via a USB hub – connect the USB cable directly to the PC
  • It may be necessary to run the heimdall flash command as root in Linux or Mac OS X: sudo heimdall flash [...]. Typical symptoms of this are:
    • a blue bar doesn’t show up after the process has finished
    • Failed to confirm end of file transfer sequence!
  • It may be necessary to capitalize the name of the partition on some devices. Try --KERNEL instead of --kernel and/or --recovery instead of --RECOVERY.
  • If on Linux 64bit you get “unable to execute ./heimdall: No such file or directory”, try the 32bit version and make sure to run it with sudo: reference.
  • On Mac OS X you may see this message: “ERROR: Claiming interface failed!”. If so, you need to disable the default USB drivers with the following commands:
    sudo kextunload -b com.apple.driver.AppleUSBCDC;
    sudo kextunload -b com.apple.driver.AppleUSBCDCACMControl;
    sudo kextunload -b com.apple.driver.AppleUSBCDCACMData;
    If you have installed Samsung Kies, you may further need to unload those USB drivers with the following commands:
    sudo kextunload -b com.devguru.driver.SamsungComposite;
    sudo kextunload -b com.devguru.driver.SamsungACMData
    sudo kextunload -b com.devguru.driver.SamsungACMControl
  • Using Heimdall version 1.4.0 (the latest version available for download on the Glass Echidna website) you may see this message or one similar to it:
    Error: Failed to confirm end of PIT file transfer!
    If you experience this error, follow the instructions for compiling Heimdall from source to get the latest version on GitHub with the issue patched.

Helpful Tip

  • The stock ROM may overwrite your custom recovery on boot. To prevent this, boot immediately into recovery after leaving Download Mode instead of letting the ROM boot up normally. If your recovery is overwritten, simply redo the steps you followed above and catch it before it boots next time.
  • Note for upgrades from gingerbread to jellybean remember the recovery is changed. This means once you install do NOT restore to old-gingerbread-stock ROM from cwm-recovery.
  • To upgrade from stock/CM7/CM9/CM10.1.2/CM10.1.3 to CM10.2, you must first boot into recovery and wipe data, cache, and dalvik cache (factory reset). Due to the new partition layout in CM10.2, failing to perform these steps will result in a bootloop. See here for details; more about repartitioning here. If you missed this step before installing, boot to recovery and factory reset, then reinstall CM10.2.
  • Some users have reported connection errors if the device is connected to a USB hub. If you experience such errors it is recommended that you try connecting your device to a USB port on the motherboard.
  • Antivirus software may prevent Heimdall from connecting properly. Disable your antivirus before proceeding.
  • When Heimdall fails to connect, the Download mode may get stuck, making all further attempts fail too. To retry, you may need to restart the Download mode: turn off the phone by holding Power for 5-10 seconds (or by pulling out the battery), then boot into Download mode and run Heimdall again.
  • If Heimdall fails to connect (errors related to initializing the protocol, or transferring data):
    if you just installed the driver, try rebooting your computer and trying again.
    if you still have troubles after reboot, in Zadig try installing the libusbK driver rather than the WinUSB driver.

Installing CyanogenMod from recovery

  1. Make sure your computer has working adb.
  2. Download the CyanogenMod build package for your device that you’d like to install to your computer.
    Optional: Download 3rd party applications packages, like Google Apps which are necessary to download apps from Google Play.
  3. Place the CyanogenMod .zip package, as well as any optional .zip packages, on the root of /sdcard:
    • Using adb: adb push filename.zip /sdcard/
    Note: You can copy the .zip packages to your device using any method you are familiar with. The adb method is used here because it is universal across all devices and works in both Android and recovery mode. If you are in recovery mode, you may need to ensure /sdcard (sometimes called Internal Storage) is mounted by checking its status in the Mounts menu. If you have booted regularly, USB debugging must be enabled.
  4. If you are not already in recovery, boot to recovery mode now.
    • Home & Volume Up & Power
  5. In Team Win Recovery Project, select menu choices by tapping on the appropriately labelled button.
  6. Optional (Recommended): Select the Backup button to create a backup.
  7. Select Wipe and then Factory Reset.
  8. Select Install.
  9. Navigate to /sdcard and select the CyanogenMod .zip package.
  10. Follow the on-screen notices to install the package.
  11. Optional: Install any additional packages you wish using the same method (if you are installing multiple packages, install CyanogenMod first and then install any subsequent packages on top of it).
  12. Once installation has finished, return to the main menu and select Reboot, then System. The device will now boot into CyanogenMod.

How To Build CyanogenMod For Samsung Galaxy Note 3 (Sprint) (hltespr)

Introduction

These instructions will hopefully assist you to start with a stock Galaxy Note 3 (Sprint), unlock the bootloader (if necessary), and then download the required tools as well as the very latest source code for CyanogenMod (based on Google’s Android operating system). Using these, you can build both CyanogenMod and CyanogenMod Recovery image from source code, and then install them both to your device.

It is difficult to say how much experience is necessary to follow these instructions. While this guide is certainly not for the very very very uninitiated, these steps shouldn’t require a PhD in software development either. Some readers will have no difficulty and breeze through the steps easily. Others may struggle over the most basic operation. Because people’s experiences, backgrounds, and intuitions differ, it may be a good idea to read through just to ascertain whether you feel comfortable or are getting over your head.

Remember, you assume all risk of trying this, but you will reap the rewards! It’s pretty satisfying to boot into a fresh operating system you baked at home :) And once you’re an Android-building ninja, there will be no more need to wait for “nightly” builds from anyone. You will have at your fingertips the skills to build a full operating system from code to a running device, whenever you want. Where you go from there– maybe you’ll add a feature, fix a bug, add a translation, or use what you’ve learned to build a new app or port to a new device– or maybe you’ll never build again– it’s all really up to you.

What you’ll need

  • A Galaxy Note 3 (Sprint)
  • A relatively recent computer (Linux, OS X, or Windows) with a reasonable amount of RAM and about 100 GB of free storage (more if you enable ccache or build for multiple devices). The less RAM you have, the longer the build will take (aim for 8 GB or more). Using SSDs results in considerably faster build times than traditional hard drives.
  • A USB cable compatible with the Galaxy Note 3 (Sprint) (typically micro USB, but older devices may use mini USB or have a proprietary cable)
  • A decent internet connection & reliable electricity :)
  • Some familiarity with basic Android operation and terminology. It would help if you’ve installed custom roms on other devices and are familiar with recovery. It may also be useful to know some basic command line concepts such as cd for “change directory”, the concept of directory hierarchies, that in Linux they are separated by /, etc.

If you are not accustomed to using Linux– this is an excellent chance to learn. It’s free– just download and run a virtual machine (VM) such as Virtualbox, then install a Linux distribution such as Ubuntu (AOSP vets Ubuntu as well). Any recent 64-bit version should work great, but the latest is recommended.

Note:

You want to use a 64-bit version of Linux. A 32-bit Linux environment will only work if you are building CyanogenMod 6 and older. For CyanogenMod 10.1, if you encounter issues with 64bit host binaries, you can set BUILD_HOST_32bit=1 in your environment. This is generally not needed, though, especially with CyanogenMod 10.2 and newer.

Using a VM allows Linux to run as a guest inside your host computer– a computer in a computer, if you will. If you hate Linux for whatever reason, you can always just uninstall and delete the whole thing. (There are plenty of places to find instructions for setting up Virtualbox with Ubuntu, so I’ll leave it to you to do that.)

So let’s begin!

Build CyanogenMod and CyanogenMod Recovery

Prepare the Build Environment

Note:

You only need to do these steps the first time you build. If you previously prepared your build environment and have downloaded the CyanogenMod source code for another device, skip to Prepare the device-specific code.

Install the SDK

If you have not previously installed adb and fastboot, install the Android SDK. “SDK” stands for Software Developer Kit, and it includes useful tools that you can use to flash software, look at the system logs in real time, grab screenshots, and more– all from your computer.

Helpful Tip

While the SDK contains lots of different things– the two tools you are most interested in for building Android are adb and fastboot, located in the /platform-tools directory.

Install the Build Packages

Several “build packages” are needed to build CyanogenMod. You can install these using the package manager of your choice.

Helpful Tip

A package manager in Linux is a system used to install or remove software (usually originating from the Internet) on your computer. With Ubuntu, you can use the Ubuntu Software Center. Even better, you may also use the apt-get install command directly in the Terminal. (Learn more about the apt packaging tool system from Wikipedia.)

For both 32-bit & 64-bit systems, you’ll need: 

bc bison build-essential curl flex git gnupg gperf libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libwxgtk2.8-dev libxml2 libxml2-utils lzop maven openjdk-7-jdk pngcrush schedtool squashfs-tools xsltproc zip zlib1g-dev

In addition to the above, for 64-bit systems, get these: 

g++-multilib gcc-multilib lib32ncurses5-dev lib32readline-gplv2-dev lib32z1-dev

For Ubuntu 15.10 (wily) and newer, substitute:

  • lib32readline-gplv2-dev → lib32readline6-dev

For Ubuntu 16.04 (xenial) and newer, substitute (additionally see java notes below):

  • libwxgtk2.8-dev → libwxgtk3.0-dev
  • openjdk-7-jdk → openjdk-8-jdk

Java versions: Different versions of CyanogenMod require different versions of the JDK (Java Development Kit):

  • CyanogenMod 7 – 9: Sun/Oracle Java SE 1.6
  • CyanogenMod 10.1: Sun/Oracle Java SE 1.6 or 1.7
  • CyanogenMod 10.2 – 11.0: Sun/Oracle Java SE 1.6 or 1.7 (OpenJDK 1.7 works fine, but the build system will display a warning)
  • CyanogenMod 12.0 – 13.0: OpenJDK 1.7 (see note about OpenJDK 1.8 below)
  • CyanogenMod 14.1: OpenJDK 1.8

Ubuntu 16.04 (Xenial Xerus) or newer and OpenJDK: Since OpenJDK 1.7 was removed from the official Ubuntu repositories, you have a couple options:

  1. Obtain OpenJDK 1.7 from the openjdk-r PPA
  2. Enable experimental OpenJDK 1.8 support in CyanogenMod 13.0 (not available in earlier version). To enable OpenJDK 1.8 support, add this line to your $HOME/.bashrc file: export EXPERIMENTAL_USE_JAVA8=true.

Also see http://source.android.com/source/initializing.html which lists needed packages.

Create the directories

You will need to set up some directories in your build environment.

To create them: 

$ mkdir -p ~/bin
$ mkdir -p ~/android/system

Install the repo command

Enter the following to download the “repo” binary and make it executable (runnable): 

$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

Put the ~/bin directory in your path of execution

In recent versions of Ubuntu, ~/bin should already be in your PATH. You can check this by opening ~/.profile with a text editor and verifying the following code exists (add it if it is missing): 

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

Initialize the CyanogenMod source repository

Enter the following to initialize the repository:

Note: Make sure the cm branch entered here is the one you wish to build and is supported on your device.
$ cd ~/android/system/
$ repo init -u https://github.com/CyanogenMod/android.git -b cm-13.0

Download the source code

To start the download of all the source code to your computer: 

$ repo sync

The CM manifests include a sensible default configuration for repo, which we strongly suggest you use (i.e. don’t add any options to sync). For reference, our default values are -j 4 and -c. The -j 4 part means that there will be four simultaneous threads/connections. If you experience problems syncing, you can lower this to -j 3 or -j 2. -c will ask repo to pull in only the current branch, instead of the entire CM history.

Prepare to wait a long time while the source code downloads.

Helpful Tip

The repo sync command is used to update the latest source code from CyanogenMod and Google. Remember it, as you can do it every few days to keep your code base fresh and up-to-date.

Get prebuilt apps (CM11 and below)

Next, 

$ cd ~/android/system/vendor/cm

then enter: 

$ ./get-prebuilts

You won’t see any confirmation- just another prompt. But this should cause some prebuilt apps to be loaded and installed into the source code. Once completed, this does not need to be done again.

Prepare the device-specific code

Helpful Tip – Errors during breakfast

Different maintainers setup their device inheritance rules differently. Some require a vendor directory to be populated before breakfast will even succeed. If you receive an error here about vendor makefiles, then jump down to the next section Extract proprietary blobs. The first portion of breakfast should have succeeded at pulling in the device tree and the extract blobs script should be available. After completing that section, you can rerun breakfast hltespr

After the source downloads, ensure you are in the root of the source code (cd ~/android/system), then type: 

$ source build/envsetup.sh
$ breakfast hltespr

This will download the device specific configuration and kernel source for your device. An alternative to using the breakfast command is to build your own local manifest. To do this, you will need to locate your device on CyanogenMod’s GitHub and list all of the repositories defined in cm.dependencies in your local manifest.

Helpful Tip

If you want to know more about what source build/envsetup.sh does or simply want to know more about the breakfast, brunch and lunch commands, you can head over to the Envsetup help page.

Helpful Tip

Instead of typing cd ~/android/system every time you want to return back to the root of the source code, here’s a short command that will do it for you: croot. To use this command, you must first run source build/envsetup.sh from ~/android/system.

Extract proprietary blobs

Now ensure that your Galaxy Note 3 (Sprint) is connected to your computer via the USB cable and that you are in the ~/android/system/device/samsung/hltespr directory (you can cd ~/android/system/device/samsung/hltespr if necessary). Then run the extract-files.sh script: 

$ ./extract-files.sh

You should see the proprietary files (aka “blobs”) get pulled from the device and moved to the ~/android/system/vendor/samsung directory. If you see errors about adb being unable to pull the files, adb may not be in the path of execution. If this is the case, see the adb page for suggestions for dealing with “command not found” errors.

Note:

Your device should already be running a build of CyanogenMod for the branch you wish to build for the extract-files.sh script to function properly.

Note:

It’s important that these proprietary files are extracted to the ~/android/system/vendor/samsung directory by using the extract-files.sh script. Makefiles are generated at the same time to make sure the blobs are eventually copied to the device. Without these blobs, CyanogenMod may build without error, but you’ll be missing important functionality, such as graphics libraries that enable you to see anything!

Turn on caching to speed up build

You can speed up subsequent builds by adding 

export USE_CCACHE=1

to your ~/.bashrc file (what’s a .bashrc file?). Then, specify the amount of disk space to dedicate to ccache by typing this from the top of your Android tree: 

prebuilts/misc/linux-x86/ccache/ccache -M 50G

where 50G corresponds to 50GB of cache. This only needs to be run once and the setting will be remembered. Anywhere in the range of 25GB to 100GB will result in very noticeably increased build speeds (for instance, a typical 1hr build time can be reduced to 20min). If you’re only building for one device, 25GB-50GB is fine. If you plan to build for several devices that do not share the same kernel source, aim for 75GB-100GB. This space will be permanently occupied on your drive, so take this into consideration. See more information about ccache on Google’s android build environment initialization page.

Helpful Tip

If you are a very active developer, working on many other projects than just Android, you might prefer to keep your Android ccache independent (because it’s huge and can slow down the efficiency of ccache in your other projects). Beginning with CyanogenMod 12.1, you can specify environment variables for the location and size of CyanogenMod’s ccache. Some syntax examples: export ANDROID_CCACHE_DIR="$HOME/android/.ccache" and export ANDROID_CCACHE_SIZE="50G".

Start the build

Time to start building! So now type: 

$ croot
$ brunch hltespr

The build should begin.

Helpful Tip

If the build doesn’t start, try lunch and choose your device from the menu. If that doesn’t work, try breakfast and choose from the menu. The command make hltespr should then work.

Helpful Tip

A second, bonus tip! If you get a command not found error for croot, brunch, or lunch, be sure you’ve done the source build/envsetup.sh command in this Terminal session from the ~/android/system directory.

Helpful Tip

A third tip! If the build to fails while downloading Gello, you’ll need to import a missing certificate into Maven’s truststore. Detailed instructions on how to do that can be found here

If the build breaks…

  • If you experience this not-enough-memory-related error…
ERROR: signapk.jar failed: return code 1make: *** [out/target/product/hltespr/cm_hltespr-ota-eng.root.zip] Error 1

…you may want to make the following change to ~/android/system/build/tools/releasetools/common.py:

Search for instances of -Xmx2048m (it should appear either under OPTIONS.java_args or near usage of signapk.jar), and replace it with -Xmx1024m or -Xmx512m.

Then start the build again (with brunch).

  • If you see a message about things suddenly being “killed” for no reason, your (virtual) machine may have run out of memory or storage space. Assign it more resources and try again.

Install the build

Assuming the build completed without error (it will be obvious when it finishes), type: 

$ cd $OUT

in the same terminal window that you did the build. Here you’ll find all the files that were created. The stuff that will go in /system is in a folder called system. The stuff that will become your ramdisk is in a folder called root. And your kernel is called… kernel.

But that’s all just background info. The two files we are interested in are (1) recovery.img, which contains CyanogenMod Recovery, and (2) cm-13.0-20161224-UNOFFICIAL-hltespr.zip, which is the CyanogenMod installation package.

Install CyanogenMod

Back to the $OUT directory on your computer– you should see a file that looks something like: 

cm-13.0-20161224-UNOFFICIAL-hltespr.zip

Note:

The above file name may vary depending on the version of CM you are building. Your build may not include a version number or may identify itself as a “KANG” rather than UNOFFICIAL version. Regardless, the file name will end in .zip and should be titled similarly to official builds.

Now you can flash the cm...zip file above as usual via recovery mode. Before doing so, now is a good time to make a backup of whatever installation is currently running on the device in case something goes wrong with the flash attempt. While CyanogenMod Recovery doesn’t have a backup feature, there are other custom recoveries available that do. You can also use something like Titanium Backup (root required) as an alternative.

Success! So….what’s next?

You’ve done it! Welcome to the elite club of self-builders. You’ve built your operating system from scratch, from the ground up. You are the master/mistress of your domain… and hopefully you’ve learned a bit on the way and had some fun too.

Now that you’ve succeeded in building CyanogenMod for your device, here are some suggestions on what to do next.

Also, be sure to take a glance at the Dev Center on this wiki for all kinds of more detailed information about developer topics ranging from collecting logs, understanding what’s in the source code directories, submitting your own contributions, porting CyanogenMod to new devices, and a lot more.

How to Install CyanogenMod on the Samsung Galaxy Note 2 LTE (Verizon) (i605)

Note: DISCLAIMER

Modifying or replacing your device’s software may void your device’s warranty, lead to data loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk. No one affiliated with the CyanogenMod project is responsible for your actions. Good luck.

Installing a custom recovery

Samsung devices come with a unique boot mode called Download Mode which is very similar to Fastboot Mode on some devices with unlocked bootloaders. Heimdall is a cross-platform, open source tool for interfacing with Download Mode on Samsung devices. The preferred method of installing a custom recovery is through this boot mode. Rooting the stock firmware is neither recommended nor necessary.

  1. Download and install the Heimdall Suite
    • Windows: Extract the Heimdall suite and take note of the directory holding heimdall.exe. You can verify Heimdall is working by opening a command prompt in this directory and typing heimdall version. If you receive an error, be sure that you have the Microsoft Visual C++ 2012 Redistributable Package (x86/32bit) installed on your computer.
    • Linux: Pick the appropriate installation package based on your distribution. The -frontend packages are not required for this guide. After installation, heimdall should be available from the terminal; type heimdall version to verify installation succeeded.
    • Mac: Install the dmg package. After installation, heimdall should be available from the terminal; type heimdall version to verify installation succeeded.
    • Building from source: The source code for the Heimdall Suite is available on Github. For more details about how to compile the Heimdall Suite, please refer to the README file on Github under the relevant operating system directory. You can also refer to the Install and compile Heimdall instructions on this wiki.
  2. Download recovery — you can directly download a recovery image using the link below, or visit TWRP site to check for the latest version of recovery for your device (if your device can be found there). For general info about recoveries click here.
    Recovery: Download
    md5: 9205a08e78a88a6184ee0f102725741b
  3. Power off the Galaxy Note 2 LTE (Verizon) and connect the USB adapter to the computer but not to the Galaxy Note 2 LTE (Verizon), yet.
  4. Boot the Galaxy Note 2 LTE (Verizon) into download mode. Home & Volume Down & Power Accept the disclaimer on the device. Then, insert the USB cable into the device.
  5. Windows (only) driver installation – Skip this step if you are using Linux or Mac
    A more complete set of the following instructions can be found in the Zadig User Guide.
    1. Run zadig.exe from the Drivers folder of the Heimdall Suite.
    2. Choose Options » List All Devices from the menu.
    3. Select Samsung USB Composite Device or MSM8x60 or Gadget Serial or Device Name from the drop down menu. (If nothing relevant appears, try uninstalling any Samsung related Windows software, like Samsung Windows drivers and/or Kies).
    4. Click Replace Driver (having selecting “Install Driver” from the drop down list built into the button).
    5. If you are prompted with a warning that the installer is unable to verify the publisher of the driver, select Install this driver anyway. You may receive two more prompts about security. Select the options that allow you to carry on.
  6. At this point, familiarize yourself with the Flashing with heimdall notes below so that you are prepared for any strange behaviour if it occurs.
  7. On the computer, open a terminal (or Command Prompt on Windows) in the directory where the recovery image is located and type:
    heimdall flash --RECOVERY recovery.img --no-reboot
    Tip: The file may not be named identically to what’s in this command. If the file is wrapped in a zip or tar file, extract the file first, because heimdall isn’t going to do it for you.
  8. A blue transfer bar will appear on the device showing the recovery being transferred.
  9. Unplug the USB cable from your device.
    • NOTE: Be sure to reboot into recovery immediately after having installed the custom recovery. Otherwise the custom recovery will be overwritten and the device will reboot (appearing as though your custom recovery failed to install).
  10. Manually reboot the phone into recovery mode by performing the following. Volume Up, Home, & Power
  11. The Galaxy Note 2 LTE (Verizon) now has a custom recovery installed. Continue to the next section.

Note: Flashing with heimdall

  • In Windows 7 UAC (User Account Control) may need switching off. Once Heimdall is finished it can be re-enabled.
  • Protocol initialization can fail if the device is connected via a USB hub – connect the USB cable directly to the PC
  • It may be necessary to run the heimdall flash command as root in Linux or Mac OS X: sudo heimdall flash [...]. Typical symptoms of this are:
    • a blue bar doesn’t show up after the process has finished
    • Failed to confirm end of file transfer sequence!
  • It may be necessary to capitalize the name of the partition on some devices. Try --KERNEL instead of --kernel and/or --recovery instead of --RECOVERY.
  • If on Linux 64bit you get “unable to execute ./heimdall: No such file or directory”, try the 32bit version and make sure to run it with sudo: reference.
  • On Mac OS X you may see this message: “ERROR: Claiming interface failed!”. If so, you need to disable the default USB drivers with the following commands:
    sudo kextunload -b com.apple.driver.AppleUSBCDC;
    sudo kextunload -b com.apple.driver.AppleUSBCDCACMControl;
    sudo kextunload -b com.apple.driver.AppleUSBCDCACMData;
    If you have installed Samsung Kies, you may further need to unload those USB drivers with the following commands:
    sudo kextunload -b com.devguru.driver.SamsungComposite;
    sudo kextunload -b com.devguru.driver.SamsungACMData
    sudo kextunload -b com.devguru.driver.SamsungACMControl
  • Using Heimdall version 1.4.0 (the latest version available for download on the Glass Echidna website) you may see this message or one similar to it:
    Error: Failed to confirm end of PIT file transfer!
    If you experience this error, follow the instructions for compiling Heimdall from source to get the latest version on GitHub with the issue patched.

Helpful Tip

  • The stock ROM may overwrite your custom recovery on boot. To prevent this, boot immediately into recovery after leaving Download Mode instead of letting the ROM boot up normally. If your recovery is overwritten, simply redo the steps you followed above and catch it before it boots next time.
  • Note for upgrades from gingerbread to jellybean remember the recovery is changed. This means once you install do NOT restore to old-gingerbread-stock ROM from cwm-recovery.
  • To upgrade from stock/CM7/CM9/CM10.1.2/CM10.1.3 to CM10.2, you must first boot into recovery and wipe data, cache, and dalvik cache (factory reset). Due to the new partition layout in CM10.2, failing to perform these steps will result in a bootloop. See here for details; more about repartitioning here. If you missed this step before installing, boot to recovery and factory reset, then reinstall CM10.2.
  • Some users have reported connection errors if the device is connected to a USB hub. If you experience such errors it is recommended that you try connecting your device to a USB port on the motherboard.
  • Antivirus software may prevent Heimdall from connecting properly. Disable your antivirus before proceeding.
  • When Heimdall fails to connect, the Download mode may get stuck, making all further attempts fail too. To retry, you may need to restart the Download mode: turn off the phone by holding Power for 5-10 seconds (or by pulling out the battery), then boot into Download mode and run Heimdall again.
  • If Heimdall fails to connect (errors related to initializing the protocol, or transferring data):
    if you just installed the driver, try rebooting your computer and trying again.
    if you still have troubles after reboot, in Zadig try installing the libusbK driver rather than the WinUSB driver.

Installing CyanogenMod from recovery

  1. Make sure your computer has working adb.
  2. Download the CyanogenMod build package for your device that you’d like to install to your computer.
    Optional: Download 3rd party applications packages, like Google Apps which are necessary to download apps from Google Play.
  3. Place the CyanogenMod .zip package, as well as any optional .zip packages, on the root of /sdcard:
    • Using adb: adb push filename.zip /sdcard/
    Note: You can copy the .zip packages to your device using any method you are familiar with. The adb method is used here because it is universal across all devices and works in both Android and recovery mode. If you are in recovery mode, you may need to ensure /sdcard (sometimes called Internal Storage) is mounted by checking its status in the Mounts menu. If you have booted regularly, USB debugging must be enabled.
  4. If you are not already in recovery, boot to recovery mode now.
    • Volume Up, Home, & Power
  5. In Team Win Recovery Project, select menu choices by tapping on the appropriately labelled button.
  6. Optional (Recommended): Select the Backup button to create a backup.
  7. Select Wipe and then Factory Reset.
  8. Select Install.
  9. Navigate to /sdcard and select the CyanogenMod .zip package.
  10. Follow the on-screen notices to install the package.
  11. Optional: Install any additional packages you wish using the same method (if you are installing multiple packages, install CyanogenMod first and then install any subsequent packages on top of it).
  12. Once installation has finished, return to the main menu and select Reboot, then System. The device will now boot into CyanogenMod.

How To Build CyanogenMod For Samsung Galaxy Note 2 LTE (Verizon) (i605)

Introduction

These instructions will hopefully assist you to start with a stock Galaxy Note 2 LTE (Verizon), unlock the bootloader (if necessary), and then download the required tools as well as the very latest source code for CyanogenMod (based on Google’s Android operating system). Using these, you can build both CyanogenMod and CyanogenMod Recovery image from source code, and then install them both to your device.

It is difficult to say how much experience is necessary to follow these instructions. While this guide is certainly not for the very very very uninitiated, these steps shouldn’t require a PhD in software development either. Some readers will have no difficulty and breeze through the steps easily. Others may struggle over the most basic operation. Because people’s experiences, backgrounds, and intuitions differ, it may be a good idea to read through just to ascertain whether you feel comfortable or are getting over your head.

Remember, you assume all risk of trying this, but you will reap the rewards! It’s pretty satisfying to boot into a fresh operating system you baked at home :) And once you’re an Android-building ninja, there will be no more need to wait for “nightly” builds from anyone. You will have at your fingertips the skills to build a full operating system from code to a running device, whenever you want. Where you go from there– maybe you’ll add a feature, fix a bug, add a translation, or use what you’ve learned to build a new app or port to a new device– or maybe you’ll never build again– it’s all really up to you.

What you’ll need

  • A Galaxy Note 2 LTE (Verizon)
  • A relatively recent computer (Linux, OS X, or Windows) with a reasonable amount of RAM and about 100 GB of free storage (more if you enable ccache or build for multiple devices). The less RAM you have, the longer the build will take (aim for 8 GB or more). Using SSDs results in considerably faster build times than traditional hard drives.
  • A USB cable compatible with the Galaxy Note 2 LTE (Verizon) (typically micro USB, but older devices may use mini USB or have a proprietary cable)
  • A decent internet connection & reliable electricity :)
  • Some familiarity with basic Android operation and terminology. It would help if you’ve installed custom roms on other devices and are familiar with recovery. It may also be useful to know some basic command line concepts such as cd for “change directory”, the concept of directory hierarchies, that in Linux they are separated by /, etc.

If you are not accustomed to using Linux– this is an excellent chance to learn. It’s free– just download and run a virtual machine (VM) such as Virtualbox, then install a Linux distribution such as Ubuntu (AOSP vets Ubuntu as well). Any recent 64-bit version should work great, but the latest is recommended.

Note:

You want to use a 64-bit version of Linux. A 32-bit Linux environment will only work if you are building CyanogenMod 6 and older. For CyanogenMod 10.1, if you encounter issues with 64bit host binaries, you can set BUILD_HOST_32bit=1 in your environment. This is generally not needed, though, especially with CyanogenMod 10.2 and newer.

Using a VM allows Linux to run as a guest inside your host computer– a computer in a computer, if you will. If you hate Linux for whatever reason, you can always just uninstall and delete the whole thing. (There are plenty of places to find instructions for setting up Virtualbox with Ubuntu, so I’ll leave it to you to do that.)

So let’s begin!

Build CyanogenMod and CyanogenMod Recovery

Prepare the Build Environment

Note:

You only need to do these steps the first time you build. If you previously prepared your build environment and have downloaded the CyanogenMod source code for another device, skip to Prepare the device-specific code.

Install the SDK

If you have not previously installed adb and fastboot, install the Android SDK. “SDK” stands for Software Developer Kit, and it includes useful tools that you can use to flash software, look at the system logs in real time, grab screenshots, and more– all from your computer.

Helpful Tip

While the SDK contains lots of different things– the two tools you are most interested in for building Android are adb and fastboot, located in the /platform-tools directory.

Install the Build Packages

Several “build packages” are needed to build CyanogenMod. You can install these using the package manager of your choice.

Helpful Tip

A package manager in Linux is a system used to install or remove software (usually originating from the Internet) on your computer. With Ubuntu, you can use the Ubuntu Software Center. Even better, you may also use the apt-get install command directly in the Terminal. (Learn more about the apt packaging tool system from Wikipedia.)

For both 32-bit & 64-bit systems, you’ll need: 

bc bison build-essential curl flex git gnupg gperf libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libwxgtk2.8-dev libxml2 libxml2-utils lzop maven openjdk-7-jdk pngcrush schedtool squashfs-tools xsltproc zip zlib1g-dev

In addition to the above, for 64-bit systems, get these: 

g++-multilib gcc-multilib lib32ncurses5-dev lib32readline-gplv2-dev lib32z1-dev

For Ubuntu 15.10 (wily) and newer, substitute:

  • lib32readline-gplv2-dev → lib32readline6-dev

For Ubuntu 16.04 (xenial) and newer, substitute (additionally see java notes below):

  • libwxgtk2.8-dev → libwxgtk3.0-dev
  • openjdk-7-jdk → openjdk-8-jdk

Java versions: Different versions of CyanogenMod require different versions of the JDK (Java Development Kit):

  • CyanogenMod 7 – 9: Sun/Oracle Java SE 1.6
  • CyanogenMod 10.1: Sun/Oracle Java SE 1.6 or 1.7
  • CyanogenMod 10.2 – 11.0: Sun/Oracle Java SE 1.6 or 1.7 (OpenJDK 1.7 works fine, but the build system will display a warning)
  • CyanogenMod 12.0 – 13.0: OpenJDK 1.7 (see note about OpenJDK 1.8 below)
  • CyanogenMod 14.1: OpenJDK 1.8

Ubuntu 16.04 (Xenial Xerus) or newer and OpenJDK: Since OpenJDK 1.7 was removed from the official Ubuntu repositories, you have a couple options:

  1. Obtain OpenJDK 1.7 from the openjdk-r PPA
  2. Enable experimental OpenJDK 1.8 support in CyanogenMod 13.0 (not available in earlier version). To enable OpenJDK 1.8 support, add this line to your $HOME/.bashrc file: export EXPERIMENTAL_USE_JAVA8=true.

Also see http://source.android.com/source/initializing.html which lists needed packages.

Create the directories

You will need to set up some directories in your build environment.

To create them: 

$ mkdir -p ~/bin
$ mkdir -p ~/android/system

Install the repo command

Enter the following to download the “repo” binary and make it executable (runnable): 

$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

Put the ~/bin directory in your path of execution

In recent versions of Ubuntu, ~/bin should already be in your PATH. You can check this by opening ~/.profile with a text editor and verifying the following code exists (add it if it is missing): 

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

Initialize the CyanogenMod source repository

Enter the following to initialize the repository:

Note: Make sure the cm branch entered here is the one you wish to build and is supported on your device.
$ cd ~/android/system/
$ repo init -u https://github.com/CyanogenMod/android.git -b cm-13.0

Download the source code

To start the download of all the source code to your computer: 

$ repo sync

The CM manifests include a sensible default configuration for repo, which we strongly suggest you use (i.e. don’t add any options to sync). For reference, our default values are -j 4 and -c. The -j 4 part means that there will be four simultaneous threads/connections. If you experience problems syncing, you can lower this to -j 3 or -j 2. -c will ask repo to pull in only the current branch, instead of the entire CM history.

Prepare to wait a long time while the source code downloads.

Helpful Tip

The repo sync command is used to update the latest source code from CyanogenMod and Google. Remember it, as you can do it every few days to keep your code base fresh and up-to-date.

Get prebuilt apps (CM11 and below)

Next, 

$ cd ~/android/system/vendor/cm

then enter: 

$ ./get-prebuilts

You won’t see any confirmation- just another prompt. But this should cause some prebuilt apps to be loaded and installed into the source code. Once completed, this does not need to be done again.

Prepare the device-specific code

Helpful Tip – Errors during breakfast

Different maintainers setup their device inheritance rules differently. Some require a vendor directory to be populated before breakfast will even succeed. If you receive an error here about vendor makefiles, then jump down to the next section Extract proprietary blobs. The first portion of breakfast should have succeeded at pulling in the device tree and the extract blobs script should be available. After completing that section, you can rerun breakfast i605

After the source downloads, ensure you are in the root of the source code (cd ~/android/system), then type: 

$ source build/envsetup.sh
$ breakfast i605

This will download the device specific configuration and kernel source for your device. An alternative to using the breakfast command is to build your own local manifest. To do this, you will need to locate your device on CyanogenMod’s GitHub and list all of the repositories defined in cm.dependencies in your local manifest.

Helpful Tip

If you want to know more about what source build/envsetup.sh does or simply want to know more about the breakfast, brunch and lunch commands, you can head over to the Envsetup help page.

Helpful Tip

Instead of typing cd ~/android/system every time you want to return back to the root of the source code, here’s a short command that will do it for you: croot. To use this command, you must first run source build/envsetup.sh from ~/android/system.

Extract proprietary blobs

Now ensure that your Galaxy Note 2 LTE (Verizon) is connected to your computer via the USB cable and that you are in the ~/android/system/device/samsung/i605 directory (you can cd ~/android/system/device/samsung/i605 if necessary). Then run the extract-files.sh script: 

$ ./extract-files.sh

You should see the proprietary files (aka “blobs”) get pulled from the device and moved to the ~/android/system/vendor/samsung directory. If you see errors about adb being unable to pull the files, adb may not be in the path of execution. If this is the case, see the adb page for suggestions for dealing with “command not found” errors.

Note:

Your device should already be running a build of CyanogenMod for the branch you wish to build for the extract-files.sh script to function properly.

Note:

It’s important that these proprietary files are extracted to the ~/android/system/vendor/samsung directory by using the extract-files.sh script. Makefiles are generated at the same time to make sure the blobs are eventually copied to the device. Without these blobs, CyanogenMod may build without error, but you’ll be missing important functionality, such as graphics libraries that enable you to see anything!

Turn on caching to speed up build

You can speed up subsequent builds by adding 

export USE_CCACHE=1

to your ~/.bashrc file (what’s a .bashrc file?). Then, specify the amount of disk space to dedicate to ccache by typing this from the top of your Android tree: 

prebuilts/misc/linux-x86/ccache/ccache -M 50G

where 50G corresponds to 50GB of cache. This only needs to be run once and the setting will be remembered. Anywhere in the range of 25GB to 100GB will result in very noticeably increased build speeds (for instance, a typical 1hr build time can be reduced to 20min). If you’re only building for one device, 25GB-50GB is fine. If you plan to build for several devices that do not share the same kernel source, aim for 75GB-100GB. This space will be permanently occupied on your drive, so take this into consideration. See more information about ccache on Google’s android build environment initialization page.

Helpful Tip

If you are a very active developer, working on many other projects than just Android, you might prefer to keep your Android ccache independent (because it’s huge and can slow down the efficiency of ccache in your other projects). Beginning with CyanogenMod 12.1, you can specify environment variables for the location and size of CyanogenMod’s ccache. Some syntax examples: export ANDROID_CCACHE_DIR="$HOME/android/.ccache" and export ANDROID_CCACHE_SIZE="50G".

Start the build

Time to start building! So now type: 

$ croot
$ brunch i605

The build should begin.

Helpful Tip

If the build doesn’t start, try lunch and choose your device from the menu. If that doesn’t work, try breakfast and choose from the menu. The command make i605 should then work.

Helpful Tip

A second, bonus tip! If you get a command not found error for croot, brunch, or lunch, be sure you’ve done the source build/envsetup.sh command in this Terminal session from the ~/android/system directory.

Helpful Tip

A third tip! If the build to fails while downloading Gello, you’ll need to import a missing certificate into Maven’s truststore. Detailed instructions on how to do that can be found here

If the build breaks…

  • If you experience this not-enough-memory-related error…
ERROR: signapk.jar failed: return code 1make: *** [out/target/product/i605/cm_i605-ota-eng.root.zip] Error 1

…you may want to make the following change to ~/android/system/build/tools/releasetools/common.py:

Search for instances of -Xmx2048m (it should appear either under OPTIONS.java_args or near usage of signapk.jar), and replace it with -Xmx1024m or -Xmx512m.

Then start the build again (with brunch).

  • If you see a message about things suddenly being “killed” for no reason, your (virtual) machine may have run out of memory or storage space. Assign it more resources and try again.

Install the build

Assuming the build completed without error (it will be obvious when it finishes), type: 

$ cd $OUT

in the same terminal window that you did the build. Here you’ll find all the files that were created. The stuff that will go in /system is in a folder called system. The stuff that will become your ramdisk is in a folder called root. And your kernel is called… kernel.

But that’s all just background info. The two files we are interested in are (1) recovery.img, which contains CyanogenMod Recovery, and (2) cm-13.0-20161224-UNOFFICIAL-i605.zip, which is the CyanogenMod installation package.

Install CyanogenMod

Back to the $OUT directory on your computer– you should see a file that looks something like: 

cm-13.0-20161224-UNOFFICIAL-i605.zip

Note:

The above file name may vary depending on the version of CM you are building. Your build may not include a version number or may identify itself as a “KANG” rather than UNOFFICIAL version. Regardless, the file name will end in .zip and should be titled similarly to official builds.

Now you can flash the cm...zip file above as usual via recovery mode. Before doing so, now is a good time to make a backup of whatever installation is currently running on the device in case something goes wrong with the flash attempt. While CyanogenMod Recovery doesn’t have a backup feature, there are other custom recoveries available that do. You can also use something like Titanium Backup (root required) as an alternative.

Success! So….what’s next?

You’ve done it! Welcome to the elite club of self-builders. You’ve built your operating system from scratch, from the ground up. You are the master/mistress of your domain… and hopefully you’ve learned a bit on the way and had some fun too.

Now that you’ve succeeded in building CyanogenMod for your device, here are some suggestions on what to do next.

Also, be sure to take a glance at the Dev Center on this wiki for all kinds of more detailed information about developer topics ranging from collecting logs, understanding what’s in the source code directories, submitting your own contributions, porting CyanogenMod to new devices, and a lot more.

How to Install CyanogenMod on the LG Optimus G (Sprint) (ls970)

Note: DISCLAIMER

Modifying or replacing your device’s software may void your device’s warranty, lead to data loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk. No one affiliated with the CyanogenMod project is responsible for your actions. Good luck.

Important Notes

Recovery can be installed via the same app used for unlocking the bootloader: FreeGee. This does require root. Once the bootloader is unlocked, recovery may also be flashed via fastboot.

Installing a custom recovery using fastboot

See All About Recovery Images for more information about custom recoveries and their capabilities.

  1. Make sure your computer has working fastboot and adb.
  2. Download recovery — you can directly download a recovery image using the link below, or visit twrp.me to obtain the latest version of Team Win Recovery Project for your device.
    Recovery: Download
    md5: f5b2895825f6348786166cb16e749de3
  3. Connect the Optimus G (Sprint) to the computer via USB.
  4. Make sure the fastboot binary is in your PATH or that you place the recovery image in the same directory as fastboot.
  5. Open a terminal on your PC and reboot the device into fastboot mode by typing
    adb reboot bootloader
    or by using the hardware key combination for your device while it is powered off.
  6. Once the device is in fastboot mode, verify your PC sees the device by typing
    fastboot devices
    • If you don’t see your device serial number, and instead see “<waiting for device>”, fastboot is not configured properly on your machine. See fastboot documentation for more info.
    • If you see “no permissionsfastboot”, make sure your UDEV rules are setup correctly.
  7. Flash recovery onto your device by entering the following command:
    fastboot flash recovery your_recovery_image.img
    where the latter part is the filename of the recovery image.
  8. Once the flash completes successfully, reboot the device into recovery to verify the installation. Boot to recovery instructions: Hold Volume Up & Power until fastboot screen appears, then press Volume Down twice, then press Power to boot recovery.
    • Note: Some ROMs overwrite recovery at boot time so if you do not plan to immediately boot into recovery to install CyanogenMod, please be aware that this may overwrite your custom recovery with the stock one.

Installing CyanogenMod from recovery

  1. Make sure your computer has working adb.
  2. Download the CyanogenMod build package for your device that you’d like to install to your computer.
    Optional: Download 3rd party applications packages, like Google Apps which are necessary to download apps from Google Play.
  3. Place the CyanogenMod .zip package, as well as any optional .zip packages, on the root of /sdcard:

  • CyanogenMod 12.0 – 13.0: OpenJDK 1.7 (see note about OpenJDK 1.8 below)
  • CyanogenMod 14.1: OpenJDK 1.8

Ubuntu 16.04 (Xenial Xerus) or newer and OpenJDK: Since OpenJDK 1.7 was removed from the official Ubuntu repositories, you have a couple options:

  1. Obtain OpenJDK 1.7 from the openjdk-r PPA
  2. Enable experimental OpenJDK 1.8 support in CyanogenMod 13.0 (not available in earlier version). To enable OpenJDK 1.8 support, add this line to your $HOME/.bashrc file: export EXPERIMENTAL_USE_JAVA8=true.

Also see http://source.android.com/source/initializing.html which lists needed packages.

Create the directories

You will need to set up some directories in your build environment.

To create them: 

$ mkdir -p ~/bin
$ mkdir -p ~/android/system

Install the repo command

Enter the following to download the “repo” binary and make it executable (runnable): 

$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

Put the ~/bin directory in your path of execution

In recent versions of Ubuntu, ~/bin should already be in your PATH. You can check this by opening ~/.profile with a text editor and verifying the following code exists (add it if it is missing): 

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

Initialize the CyanogenMod source repository

Enter the following to initialize the repository:

Note: Make sure the cm branch entered here is the one you wish to build and is supported on your device.
$ cd ~/android/system/
$ repo init -u https://github.com/CyanogenMod/android.git -b cm-13.0

Download the source code

To start the download of all the source code to your computer: 

$ repo sync

The CM manifests include a sensible default configuration for repo, which we strongly suggest you use (i.e. don’t add any options to sync). For reference, our default values are -j 4 and -c. The -j 4 part means that there will be four simultaneous threads/connections. If you experience problems syncing, you can lower this to -j 3 or -j 2. -c will ask repo to pull in only the current branch, instead of the entire CM history.

Prepare to wait a long time while the source code downloads.

Helpful Tip

The repo sync command is used to update the latest source code from CyanogenMod and Google. Remember it, as you can do it every few days to keep your code base fresh and up-to-date.

Get prebuilt apps (CM11 and below)

Next, 

$ cd ~/android/system/vendor/cm

then enter: 

$ ./get-prebuilts

You won’t see any confirmation- just another prompt. But this should cause some prebuilt apps to be loaded and installed into the source code. Once completed, this does not need to be done again.

Prepare the device-specific code

Helpful Tip – Errors during breakfast

Different maintainers setup their device inheritance rules differently. Some require a vendor directory to be populated before breakfast will even succeed. If you receive an error here about vendor makefiles, then jump down to the next section Extract proprietary blobs. The first portion of breakfast should have succeeded at pulling in the device tree and the extract blobs script should be available. After completing that section, you can rerun breakfast ls970

After the source downloads, ensure you are in the root of the source code (cd ~/android/system), then type: 

$ source build/envsetup.sh
$ breakfast ls970

This will download the device specific configuration and kernel source for your device. An alternative to using the breakfast command is to build your own local manifest. To do this, you will need to locate your device on CyanogenMod’s GitHub and list all of the repositories defined in cm.dependencies in your local manifest.

Helpful Tip

If you want to know more about what source build/envsetup.sh does or simply want to know more about the breakfast, brunch and lunch commands, you can head over to the Envsetup help page.

Helpful Tip

Instead of typing cd ~/android/system every time you want to return back to the root of the source code, here’s a short command that will do it for you: croot. To use this command, you must first run source build/envsetup.sh from ~/android/system.

Extract proprietary blobs

Now ensure that your Optimus G (Sprint) is connected to your computer via the USB cable and that you are in the ~/android/system/device/lge/ls970 directory (you can cd ~/android/system/device/lge/ls970 if necessary). Then run the extract-files.sh script: 

$ ./extract-files.sh

You should see the proprietary files (aka “blobs”) get pulled from the device and moved to the ~/android/system/vendor/lge directory. If you see errors about adb being unable to pull the files, adb may not be in the path of execution. If this is the case, see the adb page for suggestions for dealing with “command not found” errors.

Note:

Your device should already be running a build of CyanogenMod for the branch you wish to build for the extract-files.sh script to function properly.

Note:

It’s important that these proprietary files are extracted to the ~/android/system/vendor/lge directory by using the extract-files.sh script. Makefiles are generated at the same time to make sure the blobs are eventually copied to the device. Without these blobs, CyanogenMod may build without error, but you’ll be missing important functionality, such as graphics libraries that enable you to see anything!

Turn on caching to speed up build

You can speed up subsequent builds by adding 

export USE_CCACHE=1

to your ~/.bashrc file (what’s a .bashrc file?). Then, specify the amount of disk space to dedicate to ccache by typing this from the top of your Android tree: 

prebuilts/misc/linux-x86/ccache/ccache -M 50G

where 50G corresponds to 50GB of cache. This only needs to be run once and the setting will be remembered. Anywhere in the range of 25GB to 100GB will result in very noticeably increased build speeds (for instance, a typical 1hr build time can be reduced to 20min). If you’re only building for one device, 25GB-50GB is fine. If you plan to build for several devices that do not share the same kernel source, aim for 75GB-100GB. This space will be permanently occupied on your drive, so take this into consideration. See more information about ccache on Google’s android build environment initialization page.

Helpful Tip

If you are a very active developer, working on many other projects than just Android, you might prefer to keep your Android ccache independent (because it’s huge and can slow down the efficiency of ccache in your other projects). Beginning with CyanogenMod 12.1, you can specify environment variables for the location and size of CyanogenMod’s ccache. Some syntax examples: export ANDROID_CCACHE_DIR="$HOME/android/.ccache" and export ANDROID_CCACHE_SIZE="50G".

Start the build

Time to start building! So now type: 

$ croot
$ brunch ls970

The build should begin.

Helpful Tip

If the build doesn’t start, try lunch and choose your device from the menu. If that doesn’t work, try breakfast and choose from the menu. The command make ls970 should then work.

Helpful Tip

A second, bonus tip! If you get a command not found error for croot, brunch, or lunch, be sure you’ve done the source build/envsetup.sh command in this Terminal session from the ~/android/system directory.

Helpful Tip

A third tip! If the build to fails while downloading Gello, you’ll need to import a missing certificate into Maven’s truststore. Detailed instructions on how to do that can be found here

If the build breaks…

  • If you experience this not-enough-memory-related error…
ERROR: signapk.jar failed: return code 1make: *** [out/target/product/ls970/cm_ls970-ota-eng.root.zip] Error 1

…you may want to make the following change to ~/android/system/build/tools/releasetools/common.py:

Search for instances of -Xmx2048m (it should appear either under OPTIONS.java_args or near usage of signapk.jar), and replace it with -Xmx1024m or -Xmx512m.

Then start the build again (with brunch).

  • If you see a message about things suddenly being “killed” for no reason, your (virtual) machine may have run out of memory or storage space. Assign it more resources and try again.

Install the build

Assuming the build completed without error (it will be obvious when it finishes), type: 

$ cd $OUT

in the same terminal window that you did the build. Here you’ll find all the files that were created. The stuff that will go in /system is in a folder called system. The stuff that will become your ramdisk is in a folder called root. And your kernel is called… kernel.

But that’s all just background info. The two files we are interested in are (1) recovery.img, which contains CyanogenMod Recovery, and (2) cm-13.0-20161224-UNOFFICIAL-ls970.zip, which is the CyanogenMod installation package.

Installing a custom recovery using fastboot

See All About Recovery Images for more information about custom recoveries and their capabilities.

  1. Make sure your computer has working fastboot and adb.
  1. Connect the Optimus G (Sprint) to the computer via USB.
  2. Make sure the fastboot binary is in your PATH or that you place the recovery image in the same directory as fastboot.
  3. Open a terminal on your PC and reboot the device into fastboot mode by typing
    adb reboot bootloader
    or by using the hardware key combination for your device while it is powered off.
  4. Once the device is in fastboot mode, verify your PC sees the device by typing
    fastboot devices
    • If you don’t see your device serial number, and instead see “<waiting for device>”, fastboot is not configured properly on your machine. See fastboot documentation for more info.
    • If you see “no permissionsfastboot”, make sure your UDEV rules are setup correctly.
  5. Flash recovery onto your device by entering the following command:
    fastboot flash recovery your_recovery_image.img
    where the latter part is the filename of the recovery image.
  6. Once the flash completes successfully, reboot the device into recovery to verify the installation.
    • Note: Some ROMs overwrite recovery at boot time so if you do not plan to immediately boot into recovery to install CyanogenMod, please be aware that this may overwrite your custom recovery with the stock one.

Install CyanogenMod

Back to the $OUT directory on your computer– you should see a file that looks something like: 

cm-13.0-20161224-UNOFFICIAL-ls970.zip

Note:

The above file name may vary depending on the version of CM you are building. Your build may not include a version number or may identify itself as a “KANG” rather than UNOFFICIAL version. Regardless, the file name will end in .zip and should be titled similarly to official builds.

Now you can flash the cm...zip file above as usual via recovery mode. Before doing so, now is a good time to make a backup of whatever installation is currently running on the device in case something goes wrong with the flash attempt. While CyanogenMod Recovery doesn’t have a backup feature, there are other custom recoveries available that do. You can also use something like Titanium Backup (root required) as an alternative.

Success! So….what’s next?

You’ve done it! Welcome to the elite club of self-builders. You’ve built your operating system from scratch, from the ground up. You are the master/mistress of your domain… and hopefully you’ve learned a bit on the way and had some fun too.

Now that you’ve succeeded in building CyanogenMod for your device, here are some suggestions on what to do next.

Also, be sure to take a glance at the Dev Center on this wiki for all kinds of more detailed information about developer topics ranging from collecting logs, understanding what’s in the source code directories, submitting your own contributions, porting CyanogenMod to new devices, and a lot more.

Unlock and Install a Custom Recovery on the Transformer Pad

Obtaining the Bootloader Unlock Application

If the Bootloader on the Transformer Pad has already been unlocked, you may skip this section.

  1. Configure your computer for using ADB and fastboot.
  2. Navigate to Asus’ support site for the Transformer Pad.
  3. From the drop-down menu, select Android.
  4. Expand the section titled Utilities.
  5. Download the Unlock Device App.
  6. If the downloaded file is packaged in a zip archive, extract it.
  7. Open a command prompt or terminal to the location where the UnLock Device App apk resides.
  8. Install the apk using adb:
    adb install Name_of_unlock_app.apk
    For example, on the tf701 device, it would be adb install 0820-0954_SIGNED_UnLock_for_TF701_repart.apk
  9. Run the application “Unlock Device Tool” from the device and agree to the terms.
    Note 1: if you have two-factor authentication enabled on your Google account, you will have to generate an individual app password on the Google accounts settings website, as the ASUS unlock app does not natively support two-factor.
    Note 2: After you agree with the terms, the Asus unlock app will ask you to login with your gmail account. If your password does not works, then you need to enable temporary access for less secure apps at https://www.google.com/settings/security/lesssecureapps .
  10. Reboot the device.

Installing recovery using fastboot

See All About Recovery Images for more information about custom recoveries and their capabilities.

  1. If you haven’t done so already, configure your computer for using ADB and fastboot.
  2. Download recovery — you can directly download the recovery image using the link below, or visit the CWM or TWRP site to check for the latest version of custom recovery (if your device can be found there). Be careful to select the right image!
  3. Connect the Transformer Pad to the computer via USB.
  4. Make sure the fastboot binary is in your PATH or that you place the downloaded image in the same directory as fastboot.
  5. Open a terminal on your PC and reboot the device into fastboot mode by typing adb reboot bootloader or by using the hardware key combination.
    If your stock ROM is a Jellybean release, this should drop you into fastboot mode. If your stock ROM is an ICS release, you will likely need to use the Vol Down key to highlight fastboot from a boot menu and then and press Power to select it.
  6. Once the device is in fastboot mode, verify your PC sees the device by typing fastboot devices
    • If you don’t see your device serial number, and instead see “<waiting for device>”, fastboot is not configured properly on your machine. See fastboot documentation for more info.
    • If you see “no permissionsfastboot”, make sure your UDEV rules are setup correctly.
  7. Flash recovery onto your device by entering the following command: fastboot flash recovery your_recovery_image.img where the latter part is the name of the file you downloaded.
  8. Once the flash completes successfully, reboot the device into recovery to verify the installation.
    • Note: Some ROMs overwrite recovery at boot time so if you do not plan to immediately boot into recovery to install CyanogenMod, please be aware that this may overwrite your custom recovery with the stock one.

The Transformer Pad should now be ready to install CyanogenMod.

Installing CyanogenMod from recovery

  1. Make sure your computer has working adb.
  2. Download the CyanogenMod build package for your device that you’d like to install to your computer.
    Optional: Download 3rd party applications packages, like Google Apps which are necessary to download apps from Google Play.
  3. Place the CyanogenMod .zip package, as well as any optional .zip packages, on the root of /sdcard:
    • Using adb: adb push filename.zip /sdcard/
    Note: You can copy the .zip packages to your device using any method you are familiar with. The adb method is used here because it is universal across all devices and works in both Android and recovery mode. If you are in recovery mode, you may need to ensure /sdcard (sometimes called Internal Storage) is mounted by checking its status in the Mounts menu. If you have booted regularly, USB debugging must be enabled.
  4. If you are not already in recovery, boot to recovery mode now.
  5. In Team Win Recovery Project, select menu choices by tapping on the appropriately labelled button.
  6. Optional (Recommended): Select the Backup button to create a backup.
  7. Select Wipe and then Factory Reset.
  8. Select Install.
  9. Navigate to /sdcard and select the CyanogenMod .zip package.
  10. Follow the on-screen notices to install the package.
  11. Optional: Install any additional packages you wish using the same method (if you are installing multiple packages, install CyanogenMod first and then install any subsequent packages on top of it).
  12. Once installation has finished, return to the main menu and select Reboot, then System. The device will now boot into CyanogenMod.

How To Build CyanogenMod For Asus Transformer Pad (tf300t)

Introduction

These instructions will hopefully assist you to start with a stock Transformer Pad, unlock the bootloader (if necessary), and then download the required tools as well as the very latest source code for CyanogenMod (based on Google’s Android operating system). Using these, you can build both CyanogenMod and CyanogenMod Recovery image from source code, and then install them both to your device.

It is difficult to say how much experience is necessary to follow these instructions. While this guide is certainly not for the very very very uninitiated, these steps shouldn’t require a PhD in software development either. Some readers will have no difficulty and breeze through the steps easily. Others may struggle over the most basic operation. Because people’s experiences, backgrounds, and intuitions differ, it may be a good idea to read through just to ascertain whether you feel comfortable or are getting over your head.

Remember, you assume all risk of trying this, but you will reap the rewards! It’s pretty satisfying to boot into a fresh operating system you baked at home :) And once you’re an Android-building ninja, there will be no more need to wait for “nightly” builds from anyone. You will have at your fingertips the skills to build a full operating system from code to a running device, whenever you want. Where you go from there– maybe you’ll add a feature, fix a bug, add a translation, or use what you’ve learned to build a new app or port to a new device– or maybe you’ll never build again– it’s all really up to you.

What you’ll need

  • A Transformer Pad
  • A relatively recent computer (Linux, OS X, or Windows) with a reasonable amount of RAM and about 100 GB of free storage (more if you enable ccache or build for multiple devices). The less RAM you have, the longer the build will take (aim for 8 GB or more). Using SSDs results in considerably faster build times than traditional hard drives.
  • A USB cable compatible with the Transformer Pad (typically micro USB, but older devices may use mini USB or have a proprietary cable)
  • A decent internet connection & reliable electricity :)
  • Some familiarity with basic Android operation and terminology. It would help if you’ve installed custom roms on other devices and are familiar with recovery. It may also be useful to know some basic command line concepts such as cd for “change directory”, the concept of directory hierarchies, that in Linux they are separated by /, etc.

If you are not accustomed to using Linux– this is an excellent chance to learn. It’s free– just download and run a virtual machine (VM) such as Virtualbox, then install a Linux distribution such as Ubuntu (AOSP vets Ubuntu as well). Any recent 64-bit version should work great, but the latest is recommended.

Note:

You want to use a 64-bit version of Linux. A 32-bit Linux environment will only work if you are building CyanogenMod 6 and older. For CyanogenMod 10.1, if you encounter issues with 64bit host binaries, you can set BUILD_HOST_32bit=1 in your environment. This is generally not needed, though, especially with CyanogenMod 10.2 and newer.

Using a VM allows Linux to run as a guest inside your host computer– a computer in a computer, if you will. If you hate Linux for whatever reason, you can always just uninstall and delete the whole thing. (There are plenty of places to find instructions for setting up Virtualbox with Ubuntu, so I’ll leave it to you to do that.)

So let’s begin!

Build CyanogenMod and CyanogenMod Recovery

Prepare the Build Environment

Note:

You only need to do these steps the first time you build. If you previously prepared your build environment and have downloaded the CyanogenMod source code for another device, skip to Prepare the device-specific code.

Install the SDK

If you have not previously installed adb and fastboot, install the Android SDK. “SDK” stands for Software Developer Kit, and it includes useful tools that you can use to flash software, look at the system logs in real time, grab screenshots, and more– all from your computer.

Helpful Tip

While the SDK contains lots of different things– the two tools you are most interested in for building Android are adb and fastboot, located in the /platform-tools directory.

Install the Build Packages

Several “build packages” are needed to build CyanogenMod. You can install these using the package manager of your choice.

Helpful Tip

A package manager in Linux is a system used to install or remove software (usually originating from the Internet) on your computer. With Ubuntu, you can use the Ubuntu Software Center. Even better, you may also use the apt-get install command directly in the Terminal. (Learn more about the apt packaging tool system from Wikipedia.)

For both 32-bit & 64-bit systems, you’ll need: 

bc bison build-essential curl flex git gnupg gperf libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libwxgtk2.8-dev libxml2 libxml2-utils lzop maven openjdk-7-jdk pngcrush schedtool squashfs-tools xsltproc zip zlib1g-dev

In addition to the above, for 64-bit systems, get these: 

g++-multilib gcc-multilib lib32ncurses5-dev lib32readline-gplv2-dev lib32z1-dev

For Ubuntu 15.10 (wily) and newer, substitute:

  • lib32readline-gplv2-dev → lib32readline6-dev

For Ubuntu 16.04 (xenial) and newer, substitute (additionally see java notes below):

  • libwxgtk2.8-dev → libwxgtk3.0-dev
  • openjdk-7-jdk → openjdk-8-jdk

Java versions: Different versions of CyanogenMod require different versions of the JDK (Java Development Kit):

  • CyanogenMod 7 – 9: Sun/Oracle Java SE 1.6
  • CyanogenMod 10.1: Sun/Oracle Java SE 1.6 or 1.7
  • CyanogenMod 10.2 – 11.0: Sun/Oracle Java SE 1.6 or 1.7 (OpenJDK 1.7 works fine, but the build system will display a warning)
  • CyanogenMod 12.0 – 13.0: OpenJDK 1.7 (see note about OpenJDK 1.8 below)
  • CyanogenMod 14.1: OpenJDK 1.8

Ubuntu 16.04 (Xenial Xerus) or newer and OpenJDK: Since OpenJDK 1.7 was removed from the official Ubuntu repositories, you have a couple options:

  1. Obtain OpenJDK 1.7 from the openjdk-r PPA
  2. Enable experimental OpenJDK 1.8 support in CyanogenMod 13.0 (not available in earlier version). To enable OpenJDK 1.8 support, add this line to your $HOME/.bashrc file: export EXPERIMENTAL_USE_JAVA8=true.

Also see http://source.android.com/source/initializing.html which lists needed packages.

Create the directories

You will need to set up some directories in your build environment.

To create them: 

$ mkdir -p ~/bin
$ mkdir -p ~/android/system

Install the repo command

Enter the following to download the “repo” binary and make it executable (runnable): 

$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

Put the ~/bin directory in your path of execution

In recent versions of Ubuntu, ~/bin should already be in your PATH. You can check this by opening ~/.profile with a text editor and verifying the following code exists (add it if it is missing): 

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

Initialize the CyanogenMod source repository

Enter the following to initialize the repository:

Note: Make sure the cm branch entered here is the one you wish to build and is supported on your device.
$ cd ~/android/system/
$ repo init -u https://github.com/CyanogenMod/android.git -b cm-13.0

Download the source code

To start the download of all the source code to your computer: 

$ repo sync

The CM manifests include a sensible default configuration for repo, which we strongly suggest you use (i.e. don’t add any options to sync). For reference, our default values are -j 4 and -c. The -j 4 part means that there will be four simultaneous threads/connections. If you experience problems syncing, you can lower this to -j 3 or -j 2. -c will ask repo to pull in only the current branch, instead of the entire CM history.

Prepare to wait a long time while the source code downloads.

Helpful Tip

The repo sync command is used to update the latest source code from CyanogenMod and Google. Remember it, as you can do it every few days to keep your code base fresh and up-to-date.

Get prebuilt apps (CM11 and below)

Next, 

$ cd ~/android/system/vendor/cm

then enter: 

$ ./get-prebuilts

You won’t see any confirmation- just another prompt. But this should cause some prebuilt apps to be loaded and installed into the source code. Once completed, this does not need to be done again.

Prepare the device-specific code

Helpful Tip – Errors during breakfast

Different maintainers setup their device inheritance rules differently. Some require a vendor directory to be populated before breakfast will even succeed. If you receive an error here about vendor makefiles, then jump down to the next section Extract proprietary blobs. The first portion of breakfast should have succeeded at pulling in the device tree and the extract blobs script should be available. After completing that section, you can rerun breakfast tf300t

After the source downloads, ensure you are in the root of the source code (cd ~/android/system), then type: 

$ source build/envsetup.sh
$ breakfast tf300t

This will download the device specific configuration and kernel source for your device. An alternative to using the breakfast command is to build your own local manifest. To do this, you will need to locate your device on CyanogenMod’s GitHub and list all of the repositories defined in cm.dependencies in your local manifest.

Helpful Tip

If you want to know more about what source build/envsetup.sh does or simply want to know more about the breakfast, brunch and lunch commands, you can head over to the Envsetup help page.

Helpful Tip

Instead of typing cd ~/android/system every time you want to return back to the root of the source code, here’s a short command that will do it for you: croot. To use this command, you must first run source build/envsetup.sh from ~/android/system.

Extract proprietary blobs

Now ensure that your Transformer Pad is connected to your computer via the USB cable and that you are in the ~/android/system/device/asus/tf300t directory (you can cd ~/android/system/device/asus/tf300t if necessary). Then run the extract-files.sh script: 

$ ./extract-files.sh

You should see the proprietary files (aka “blobs”) get pulled from the device and moved to the ~/android/system/vendor/asus directory. If you see errors about adb being unable to pull the files, adb may not be in the path of execution. If this is the case, see the adb page for suggestions for dealing with “command not found” errors.

Note:

Your device should already be running a build of CyanogenMod for the branch you wish to build for the extract-files.sh script to function properly.

Note:

It’s important that these proprietary files are extracted to the ~/android/system/vendor/asus directory by using the extract-files.sh script. Makefiles are generated at the same time to make sure the blobs are eventually copied to the device. Without these blobs, CyanogenMod may build without error, but you’ll be missing important functionality, such as graphics libraries that enable you to see anything!

Turn on caching to speed up build

You can speed up subsequent builds by adding 

export USE_CCACHE=1

to your ~/.bashrc file (what’s a .bashrc file?). Then, specify the amount of disk space to dedicate to ccache by typing this from the top of your Android tree: 

prebuilts/misc/linux-x86/ccache/ccache -M 50G

where 50G corresponds to 50GB of cache. This only needs to be run once and the setting will be remembered. Anywhere in the range of 25GB to 100GB will result in very noticeably increased build speeds (for instance, a typical 1hr build time can be reduced to 20min). If you’re only building for one device, 25GB-50GB is fine. If you plan to build for several devices that do not share the same kernel source, aim for 75GB-100GB. This space will be permanently occupied on your drive, so take this into consideration. See more information about ccache on Google’s android build environment initialization page.

Helpful Tip

If you are a very active developer, working on many other projects than just Android, you might prefer to keep your Android ccache independent (because it’s huge and can slow down the efficiency of ccache in your other projects). Beginning with CyanogenMod 12.1, you can specify environment variables for the location and size of CyanogenMod’s ccache. Some syntax examples: export ANDROID_CCACHE_DIR="$HOME/android/.ccache" and export ANDROID_CCACHE_SIZE="50G".

Start the build

Time to start building! So now type: 

$ croot
$ brunch tf300t

The build should begin.

Helpful Tip

If the build doesn’t start, try lunch and choose your device from the menu. If that doesn’t work, try breakfast and choose from the menu. The command make tf300t should then work.

Helpful Tip

A second, bonus tip! If you get a command not found error for croot, brunch, or lunch, be sure you’ve done the source build/envsetup.sh command in this Terminal session from the ~/android/system directory.

Helpful Tip

A third tip! If the build to fails while downloading Gello, you’ll need to import a missing certificate into Maven’s truststore. Detailed instructions on how to do that can be found here

If the build breaks…

  • If you experience this not-enough-memory-related error…
ERROR: signapk.jar failed: return code 1make: *** [out/target/product/tf300t/cm_tf300t-ota-eng.root.zip] Error 1

…you may want to make the following change to ~/android/system/build/tools/releasetools/common.py:

Search for instances of -Xmx2048m (it should appear either under OPTIONS.java_args or near usage of signapk.jar), and replace it with -Xmx1024m or -Xmx512m.

Then start the build again (with brunch).

  • If you see a message about things suddenly being “killed” for no reason, your (virtual) machine may have run out of memory or storage space. Assign it more resources and try again.

Install the build

Assuming the build completed without error (it will be obvious when it finishes), type: 

$ cd $OUT

in the same terminal window that you did the build. Here you’ll find all the files that were created. The stuff that will go in /system is in a folder called system. The stuff that will become your ramdisk is in a folder called root. And your kernel is called… kernel.

But that’s all just background info. The two files we are interested in are (1) recovery.img, which contains CyanogenMod Recovery, and (2) cm-13.0-20161224-UNOFFICIAL-tf300t.zip, which is the CyanogenMod installation package.

Install CyanogenMod

Back to the $OUT directory on your computer– you should see a file that looks something like: 

cm-13.0-20161224-UNOFFICIAL-tf300t.zip

Note:

The above file name may vary depending on the version of CM you are building. Your build may not include a version number or may identify itself as a “KANG” rather than UNOFFICIAL version. Regardless, the file name will end in .zip and should be titled similarly to official builds.

Now you can flash the cm...zip file above as usual via recovery mode. Before doing so, now is a good time to make a backup of whatever installation is currently running on the device in case something goes wrong with the flash attempt. While CyanogenMod Recovery doesn’t have a backup feature, there are other custom recoveries available that do. You can also use something like Titanium Backup (root required) as an alternative.

Success! So….what’s next?

You’ve done it! Welcome to the elite club of self-builders. You’ve built your operating system from scratch, from the ground up. You are the master/mistress of your domain… and hopefully you’ve learned a bit on the way and had some fun too.

Now that you’ve succeeded in building CyanogenMod for your device, here are some suggestions on what to do next.

Also, be sure to take a glance at the Dev Center on this wiki for all kinds of more detailed information about developer topics ranging from collecting logs, understanding what’s in the source code directories, submitting your own contributions, porting CyanogenMod to new devices, and a lot more.

How to Install CyanogenMod on the LG Optimus G (ATT) (e970)

Note: DISCLAIMER

Modifying or replacing your device’s software may void your device’s warranty, lead to data loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk. No one affiliated with the CyanogenMod project is responsible for your actions. Good luck.

Important Notes

Recovery can be installed via the same app used for unlocking the bootloader: FreeGee. This does require root. Once the bootloader is unlocked, recovery may also be flashed via fastboot.

Installing a custom recovery using fastboot

See All About Recovery Images for more information about custom recoveries and their capabilities.

  1. Make sure your computer has working fastboot and adb.
  2. Download recovery — you can directly download a recovery image using the link below, or visit twrp.me to obtain the latest version of Team Win Recovery Project for your device.
    Recovery: Download
    md5: 531fca48e4ddeb32043f6e1c488d8bd0
  3. Connect the Optimus G (ATT) to the computer via USB.
  4. Make sure the fastboot binary is in your PATH or that you place the recovery image in the same directory as fastboot.
  5. Open a terminal on your PC and reboot the device into fastboot mode by typing
    adb reboot bootloader
    or by using the hardware key combination for your device while it is powered off.
  6. Once the device is in fastboot mode, verify your PC sees the device by typing
    fastboot devices
    • If you don’t see your device serial number, and instead see “<waiting for device>”, fastboot is not configured properly on your machine. See fastboot documentation for more info.
    • If you see “no permissionsfastboot”, make sure your UDEV rules are setup correctly.
  7. Flash recovery onto your device by entering the following command:
    fastboot flash recovery your_recovery_image.img
    where the latter part is the filename of the recovery image.
  8. Once the flash completes successfully, reboot the device into recovery to verify the installation. Boot to recovery instructions: Hold Volume Up & Power until fastboot screen appears, then press Volume Down twice, then press Power to boot recovery.
    • Note: Some ROMs overwrite recovery at boot time so if you do not plan to immediately boot into recovery to install CyanogenMod, please be aware that this may overwrite your custom recovery with the stock one.

Installing CyanogenMod from recovery

  1. Make sure your computer has working adb.
  2. Download the CyanogenMod build package for your device that you’d like to install to your computer.
    Optional: Download 3rd party applications packages, like Google Apps which are necessary to download apps from Google Play.
  3. Place the CyanogenMod .zip package, as well as any optional .zip packages, on the root of /sdcard:
    • Using adb: adb push filename.zip /sdcard/
    Note: You can copy the .zip packages to your device using any method you are familiar with. The adb method is used here because it is universal across all devices and works in both Android and recovery mode. If you are in recovery mode, you may need to ensure /sdcard (sometimes called Internal Storage) is mounted by checking its status in the Mounts menu. If you have booted regularly, USB debugging must be enabled.
  4. If you are not already in recovery, boot to recovery mode now.
    • Hold Volume Up & Power until fastboot screen appears, then press Volume Down twice, then press Power to boot recovery.
  5. In Team Win Recovery Project, select menu choices by tapping on the appropriately labelled button.
  6. Optional (Recommended): Select the Backup button to create a backup.
  7. Select Wipe and then Factory Reset.
  8. Select Install.
  9. Navigate to /sdcard and select the CyanogenMod .zip package.
  10. Follow the on-screen notices to install the package.
  11. Optional: Install any additional packages you wish using the same method (if you are installing multiple packages, install CyanogenMod first and then install any subsequent packages on top of it).
  12. Once installation has finished, return to the main menu and select Reboot, then System. The device will now boot into CyanogenMod.

How To Build CyanogenMod For LG Optimus G (“e975”)

Introduction

These instructions will hopefully assist you to start with a stock Optimus G, unlock the bootloader (if necessary), and then download the required tools as well as the very latest source code for CyanogenMod (based on Google’s Android operating system). Using these, you can build both CyanogenMod and CyanogenMod Recovery image from source code, and then install them both to your device.

It is difficult to say how much experience is necessary to follow these instructions. While this guide is certainly not for the very very very uninitiated, these steps shouldn’t require a PhD in software development either. Some readers will have no difficulty and breeze through the steps easily. Others may struggle over the most basic operation. Because people’s experiences, backgrounds, and intuitions differ, it may be a good idea to read through just to ascertain whether you feel comfortable or are getting over your head.

Remember, you assume all risk of trying this, but you will reap the rewards! It’s pretty satisfying to boot into a fresh operating system you baked at home :) And once you’re an Android-building ninja, there will be no more need to wait for “nightly” builds from anyone. You will have at your fingertips the skills to build a full operating system from code to a running device, whenever you want. Where you go from there– maybe you’ll add a feature, fix a bug, add a translation, or use what you’ve learned to build a new app or port to a new device– or maybe you’ll never build again– it’s all really up to you.

What you’ll need

  • A Optimus G
  • A relatively recent computer (Linux, OS X, or Windows) with a reasonable amount of RAM and about 100 GB of free storage (more if you enable ccache or build for multiple devices). The less RAM you have, the longer the build will take (aim for 8 GB or more). Using SSDs results in considerably faster build times than traditional hard drives.
  • A USB cable compatible with the Optimus G (typically micro USB, but older devices may use mini USB or have a proprietary cable)
  • A decent internet connection & reliable electricity :)
  • Some familiarity with basic Android operation and terminology. It would help if you’ve installed custom roms on other devices and are familiar with recovery. It may also be useful to know some basic command line concepts such as cd for “change directory”, the concept of directory hierarchies, that in Linux they are separated by /, etc.

If you are not accustomed to using Linux– this is an excellent chance to learn. It’s free– just download and run a virtual machine (VM) such as Virtualbox, then install a Linux distribution such as Ubuntu (AOSP vets Ubuntu as well). Any recent 64-bit version should work great, but the latest is recommended.

Note:

You want to use a 64-bit version of Linux. A 32-bit Linux environment will only work if you are building CyanogenMod 6 and older. For CyanogenMod 10.1, if you encounter issues with 64bit host binaries, you can set BUILD_HOST_32bit=1 in your environment. This is generally not needed, though, especially with CyanogenMod 10.2 and newer.

Using a VM allows Linux to run as a guest inside your host computer– a computer in a computer, if you will. If you hate Linux for whatever reason, you can always just uninstall and delete the whole thing. (There are plenty of places to find instructions for setting up Virtualbox with Ubuntu, so I’ll leave it to you to do that.)

So let’s begin!

Build CyanogenMod and CyanogenMod Recovery

Prepare the Build Environment

Note:

You only need to do these steps the first time you build. If you previously prepared your build environment and have downloaded the CyanogenMod source code for another device, skip to Prepare the device-specific code.

Install the SDK

If you have not previously installed adb and fastboot, install the Android SDK. “SDK” stands for Software Developer Kit, and it includes useful tools that you can use to flash software, look at the system logs in real time, grab screenshots, and more– all from your computer.

Helpful Tip

While the SDK contains lots of different things– the two tools you are most interested in for building Android are adb and fastboot, located in the /platform-tools directory.

Install the Build Packages

Several “build packages” are needed to build CyanogenMod. You can install these using the package manager of your choice.

Helpful Tip

A package manager in Linux is a system used to install or remove software (usually originating from the Internet) on your computer. With Ubuntu, you can use the Ubuntu Software Center. Even better, you may also use the apt-get install command directly in the Terminal. (Learn more about the apt packaging tool system from Wikipedia.)

For both 32-bit & 64-bit systems, you’ll need: 

bc bison build-essential curl flex git gnupg gperf libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libwxgtk2.8-dev libxml2 libxml2-utils lzop maven openjdk-7-jdk pngcrush schedtool squashfs-tools xsltproc zip zlib1g-dev

In addition to the above, for 64-bit systems, get these: 

g++-multilib gcc-multilib lib32ncurses5-dev lib32readline-gplv2-dev lib32z1-dev

For Ubuntu 15.10 (wily) and newer, substitute:

  • lib32readline-gplv2-dev → lib32readline6-dev

For Ubuntu 16.04 (xenial) and newer, substitute (additionally see java notes below):

  • libwxgtk2.8-dev → libwxgtk3.0-dev
  • openjdk-7-jdk → openjdk-8-jdk

Java versions: Different versions of CyanogenMod require different versions of the JDK (Java Development Kit):

  • CyanogenMod 7 – 9: Sun/Oracle Java SE 1.6
  • CyanogenMod 10.1: Sun/Oracle Java SE 1.6 or 1.7
  • CyanogenMod 10.2 – 11.0: Sun/Oracle Java SE 1.6 or 1.7 (OpenJDK 1.7 works fine, but the build system will display a warning)
  • CyanogenMod 12.0 – 13.0: OpenJDK 1.7 (see note about OpenJDK 1.8 below)
  • CyanogenMod 14.1: OpenJDK 1.8

Ubuntu 16.04 (Xenial Xerus) or newer and OpenJDK: Since OpenJDK 1.7 was removed from the official Ubuntu repositories, you have a couple options:

  1. Obtain OpenJDK 1.7 from the openjdk-r PPA
  2. Enable experimental OpenJDK 1.8 support in CyanogenMod 13.0 (not available in earlier version). To enable OpenJDK 1.8 support, add this line to your $HOME/.bashrc file: export EXPERIMENTAL_USE_JAVA8=true.

Also see http://source.android.com/source/initializing.html which lists needed packages.

Create the directories

You will need to set up some directories in your build environment.

To create them: 

$ mkdir -p ~/bin
$ mkdir -p ~/android/system

Install the repo command

Enter the following to download the “repo” binary and make it executable (runnable): 

$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

Put the ~/bin directory in your path of execution

In recent versions of Ubuntu, ~/bin should already be in your PATH. You can check this by opening ~/.profile with a text editor and verifying the following code exists (add it if it is missing): 

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

Initialize the CyanogenMod source repository

Enter the following to initialize the repository:

Note: Make sure the cm branch entered here is the one you wish to build and is supported on your device.
$ cd ~/android/system/
$ repo init -u https://github.com/CyanogenMod/android.git -b cm-13.0

Download the source code

To start the download of all the source code to your computer: 

$ repo sync

The CM manifests include a sensible default configuration for repo, which we strongly suggest you use (i.e. don’t add any options to sync). For reference, our default values are -j 4 and -c. The -j 4 part means that there will be four simultaneous threads/connections. If you experience problems syncing, you can lower this to -j 3 or -j 2. -c will ask repo to pull in only the current branch, instead of the entire CM history.

Prepare to wait a long time while the source code downloads.

Helpful Tip

The repo sync command is used to update the latest source code from CyanogenMod and Google. Remember it, as you can do it every few days to keep your code base fresh and up-to-date.

Get prebuilt apps (CM11 and below)

Next, 

$ cd ~/android/system/vendor/cm

then enter: 

$ ./get-prebuilts

You won’t see any confirmation- just another prompt. But this should cause some prebuilt apps to be loaded and installed into the source code. Once completed, this does not need to be done again.

Prepare the device-specific code

Helpful Tip – Errors during breakfast

Different maintainers setup their device inheritance rules differently. Some require a vendor directory to be populated before breakfast will even succeed. If you receive an error here about vendor makefiles, then jump down to the next section Extract proprietary blobs. The first portion of breakfast should have succeeded at pulling in the device tree and the extract blobs script should be available. After completing that section, you can rerun breakfast e975

After the source downloads, ensure you are in the root of the source code (cd ~/android/system), then type: 

$ source build/envsetup.sh
$ breakfast e975

This will download the device specific configuration and kernel source for your device. An alternative to using the breakfast command is to build your own local manifest. To do this, you will need to locate your device on CyanogenMod’s GitHub and list all of the repositories defined in cm.dependencies in your local manifest.

Helpful Tip

If you want to know more about what source build/envsetup.sh does or simply want to know more about the breakfast, brunch and lunch commands, you can head over to the Envsetup help page.

Helpful Tip

Instead of typing cd ~/android/system every time you want to return back to the root of the source code, here’s a short command that will do it for you: croot. To use this command, you must first run source build/envsetup.sh from ~/android/system.

Extract proprietary blobs

Now ensure that your Optimus G is connected to your computer via the USB cable and that you are in the ~/android/system/device/lge/e975 directory (you can cd ~/android/system/device/lge/e975 if necessary). Then run the extract-files.sh script: 

$ ./extract-files.sh

You should see the proprietary files (aka “blobs”) get pulled from the device and moved to the ~/android/system/vendor/lge directory. If you see errors about adb being unable to pull the files, adb may not be in the path of execution. If this is the case, see the adb page for suggestions for dealing with “command not found” errors.

Note:

Your device should already be running a build of CyanogenMod for the branch you wish to build for the extract-files.sh script to function properly.

Note:

It’s important that these proprietary files are extracted to the ~/android/system/vendor/lge directory by using the extract-files.sh script. Makefiles are generated at the same time to make sure the blobs are eventually copied to the device. Without these blobs, CyanogenMod may build without error, but you’ll be missing important functionality, such as graphics libraries that enable you to see anything!

Turn on caching to speed up build

You can speed up subsequent builds by adding 

export USE_CCACHE=1

to your ~/.bashrc file (what’s a .bashrc file?). Then, specify the amount of disk space to dedicate to ccache by typing this from the top of your Android tree: 

prebuilts/misc/linux-x86/ccache/ccache -M 50G

where 50G corresponds to 50GB of cache. This only needs to be run once and the setting will be remembered. Anywhere in the range of 25GB to 100GB will result in very noticeably increased build speeds (for instance, a typical 1hr build time can be reduced to 20min). If you’re only building for one device, 25GB-50GB is fine. If you plan to build for several devices that do not share the same kernel source, aim for 75GB-100GB. This space will be permanently occupied on your drive, so take this into consideration. See more information about ccache on Google’s android build environment initialization page.

How To Build CyanogenMod For LG G3 (T-Mobile) (d851)

Introduction

These instructions will hopefully assist you to start with a stock G3 (T-Mobile), unlock the bootloader (if necessary), and then download the required tools as well as the very latest source code for CyanogenMod (based on Google’s Android operating system). Using these, you can build both CyanogenMod and CyanogenMod Recovery image from source code, and then install them both to your device.

It is difficult to say how much experience is necessary to follow these instructions. While this guide is certainly not for the very very very uninitiated, these steps shouldn’t require a PhD in software development either. Some readers will have no difficulty and breeze through the steps easily. Others may struggle over the most basic operation. Because people’s experiences, backgrounds, and intuitions differ, it may be a good idea to read through just to ascertain whether you feel comfortable or are getting over your head.

Remember, you assume all risk of trying this, but you will reap the rewards! It’s pretty satisfying to boot into a fresh operating system you baked at home :) And once you’re an Android-building ninja, there will be no more need to wait for “nightly” builds from anyone. You will have at your fingertips the skills to build a full operating system from code to a running device, whenever you want. Where you go from there– maybe you’ll add a feature, fix a bug, add a translation, or use what you’ve learned to build a new app or port to a new device– or maybe you’ll never build again– it’s all really up to you.

What you’ll need

  • A G3 (T-Mobile)
  • A relatively recent computer (Linux, OS X, or Windows) with a reasonable amount of RAM and about 100 GB of free storage (more if you enable ccache or build for multiple devices). The less RAM you have, the longer the build will take (aim for 8 GB or more). Using SSDs results in considerably faster build times than traditional hard drives.
  • A USB cable compatible with the G3 (T-Mobile) (typically micro USB, but older devices may use mini USB or have a proprietary cable)
  • A decent internet connection & reliable electricity :)
  • Some familiarity with basic Android operation and terminology. It would help if you’ve installed custom roms on other devices and are familiar with recovery. It may also be useful to know some basic command line concepts such as cd for “change directory”, the concept of directory hierarchies, that in Linux they are separated by /, etc.

If you are not accustomed to using Linux– this is an excellent chance to learn. It’s free– just download and run a virtual machine (VM) such as Virtualbox, then install a Linux distribution such as Ubuntu (AOSP vets Ubuntu as well). Any recent 64-bit version should work great, but the latest is recommended.

Note:

You want to use a 64-bit version of Linux. A 32-bit Linux environment will only work if you are building CyanogenMod 6 and older. For CyanogenMod 10.1, if you encounter issues with 64bit host binaries, you can set BUILD_HOST_32bit=1 in your environment. This is generally not needed, though, especially with CyanogenMod 10.2 and newer.

Using a VM allows Linux to run as a guest inside your host computer– a computer in a computer, if you will. If you hate Linux for whatever reason, you can always just uninstall and delete the whole thing. (There are plenty of places to find instructions for setting up Virtualbox with Ubuntu, so I’ll leave it to you to do that.)

So let’s begin!

Build CyanogenMod and CyanogenMod Recovery

Prepare the Build Environment

Note:

You only need to do these steps the first time you build. If you previously prepared your build environment and have downloaded the CyanogenMod source code for another device, skip to Prepare the device-specific code.

Install the SDK

If you have not previously installed adb and fastboot, install the Android SDK. “SDK” stands for Software Developer Kit, and it includes useful tools that you can use to flash software, look at the system logs in real time, grab screenshots, and more– all from your computer.

Helpful Tip

While the SDK contains lots of different things– the two tools you are most interested in for building Android are adb and fastboot, located in the /platform-tools directory.

Install the Build Packages

Several “build packages” are needed to build CyanogenMod. You can install these using the package manager of your choice.

Helpful Tip

A package manager in Linux is a system used to install or remove software (usually originating from the Internet) on your computer. With Ubuntu, you can use the Ubuntu Software Center. Even better, you may also use the apt-get install command directly in the Terminal. (Learn more about the apt packaging tool system from Wikipedia.)

For both 32-bit & 64-bit systems, you’ll need: 

bc bison build-essential curl flex git gnupg gperf libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libwxgtk2.8-dev libxml2 libxml2-utils lzop maven openjdk-7-jdk pngcrush schedtool squashfs-tools xsltproc zip zlib1g-dev

In addition to the above, for 64-bit systems, get these: 

g++-multilib gcc-multilib lib32ncurses5-dev lib32readline-gplv2-dev lib32z1-dev

For Ubuntu 15.10 (wily) and newer, substitute:

  • lib32readline-gplv2-dev → lib32readline6-dev

For Ubuntu 16.04 (xenial) and newer, substitute (additionally see java notes below):

  • libwxgtk2.8-dev → libwxgtk3.0-dev
  • openjdk-7-jdk → openjdk-8-jdk

Java versions: Different versions of CyanogenMod require different versions of the JDK (Java Development Kit):

  • CyanogenMod 7 – 9: Sun/Oracle Java SE 1.6
  • CyanogenMod 10.1: Sun/Oracle Java SE 1.6 or 1.7
  • CyanogenMod 10.2 – 11.0: Sun/Oracle Java SE 1.6 or 1.7 (OpenJDK 1.7 works fine, but the build system will display a warning)
  • CyanogenMod 12.0 – 13.0: OpenJDK 1.7 (see note about OpenJDK 1.8 below)
  • CyanogenMod 14.1: OpenJDK 1.8

Ubuntu 16.04 (Xenial Xerus) or newer and OpenJDK: Since OpenJDK 1.7 was removed from the official Ubuntu repositories, you have a couple options:

  1. Obtain OpenJDK 1.7 from the openjdk-r PPA
  2. Enable experimental OpenJDK 1.8 support in CyanogenMod 13.0 (not available in earlier version). To enable OpenJDK 1.8 support, add this line to your $HOME/.bashrc file: export EXPERIMENTAL_USE_JAVA8=true.

Also see http://source.android.com/source/initializing.html which lists needed packages.

Create the directories

You will need to set up some directories in your build environment.

To create them: 

$ mkdir -p ~/bin
$ mkdir -p ~/android/system

Install the repo command

Enter the following to download the “repo” binary and make it executable (runnable): 

$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

Put the ~/bin directory in your path of execution

In recent versions of Ubuntu, ~/bin should already be in your PATH. You can check this by opening ~/.profile with a text editor and verifying the following code exists (add it if it is missing): 

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

Initialize the CyanogenMod source repository

Enter the following to initialize the repository:

Note: Make sure the cm branch entered here is the one you wish to build and is supported on your device.
$ cd ~/android/system/
$ repo init -u https://github.com/CyanogenMod/android.git -b cm-13.0

Download the source code

To start the download of all the source code to your computer: 

$ repo sync

The CM manifests include a sensible default configuration for repo, which we strongly suggest you use (i.e. don’t add any options to sync). For reference, our default values are -j 4 and -c. The -j 4 part means that there will be four simultaneous threads/connections. If you experience problems syncing, you can lower this to -j 3 or -j 2. -c will ask repo to pull in only the current branch, instead of the entire CM history.

Prepare to wait a long time while the source code downloads.

Helpful Tip

The repo sync command is used to update the latest source code from CyanogenMod and Google. Remember it, as you can do it every few days to keep your code base fresh and up-to-date.

Get prebuilt apps (CM11 and below)

Next, 

$ cd ~/android/system/vendor/cm

then enter: 

$ ./get-prebuilts

You won’t see any confirmation- just another prompt. But this should cause some prebuilt apps to be loaded and installed into the source code. Once completed, this does not need to be done again.

Prepare the device-specific code

Helpful Tip – Errors during breakfast

Different maintainers setup their device inheritance rules differently. Some require a vendor directory to be populated before breakfast will even succeed. If you receive an error here about vendor makefiles, then jump down to the next section Extract proprietary blobs. The first portion of breakfast should have succeeded at pulling in the device tree and the extract blobs script should be available. After completing that section, you can rerun breakfast d851

After the source downloads, ensure you are in the root of the source code (cd ~/android/system), then type: 

$ source build/envsetup.sh
$ breakfast d851

This will download the device specific configuration and kernel source for your device. An alternative to using the breakfast command is to build your own local manifest. To do this, you will need to locate your device on CyanogenMod’s GitHub and list all of the repositories defined in cm.dependencies in your local manifest.

Helpful Tip

If you want to know more about what source build/envsetup.sh does or simply want to know more about the breakfast, brunch and lunch commands, you can head over to the Envsetup help page.

Helpful Tip

Instead of typing cd ~/android/system every time you want to return back to the root of the source code, here’s a short command that will do it for you: croot. To use this command, you must first run source build/envsetup.sh from ~/android/system.

Extract proprietary blobs

Now ensure that your G3 (T-Mobile) is connected to your computer via the USB cable and that you are in the ~/android/system/device/lge/d851 directory (you can cd ~/android/system/device/lge/d851 if necessary). Then run the extract-files.sh script: 

$ ./extract-files.sh

You should see the proprietary files (aka “blobs”) get pulled from the device and moved to the ~/android/system/vendor/lge directory. If you see errors about adb being unable to pull the files, adb may not be in the path of execution. If this is the case, see the adb page for suggestions for dealing with “command not found” errors.

Note:

Your device should already be running a build of CyanogenMod for the branch you wish to build for the extract-files.sh script to function properly.

Note:

It’s important that these proprietary files are extracted to the ~/android/system/vendor/lge directory by using the extract-files.sh script. Makefiles are generated at the same time to make sure the blobs are eventually copied to the device. Without these blobs, CyanogenMod may build without error, but you’ll be missing important functionality, such as graphics libraries that enable you to see anything!

Turn on caching to speed up build

You can speed up subsequent builds by adding 

export USE_CCACHE=1

to your ~/.bashrc file (what’s a .bashrc file?). Then, specify the amount of disk space to dedicate to ccache by typing this from the top of your Android tree: 

prebuilts/misc/linux-x86/ccache/ccache -M 50G

where 50G corresponds to 50GB of cache. This only needs to be run once and the setting will be remembered. Anywhere in the range of 25GB to 100GB will result in very noticeably increased build speeds (for instance, a typical 1hr build time can be reduced to 20min). If you’re only building for one device, 25GB-50GB is fine. If you plan to build for several devices that do not share the same kernel source, aim for 75GB-100GB. This space will be permanently occupied on your drive, so take this into consideration. See more information about ccache on Google’s android build environment initialization page.

Helpful Tip

If you are a very active developer, working on many other projects than just Android, you might prefer to keep your Android ccache independent (because it’s huge and can slow down the efficiency of ccache in your other projects). Beginning with CyanogenMod 12.1, you can specify environment variables for the location and size of CyanogenMod’s ccache. Some syntax examples: export ANDROID_CCACHE_DIR="$HOME/android/.ccache" and export ANDROID_CCACHE_SIZE="50G".

Start the build

Time to start building! So now type: 

$ croot
$ brunch d851

The build should begin.

Helpful Tip

If the build doesn’t start, try lunch and choose your device from the menu. If that doesn’t work, try breakfast and choose from the menu. The command make d851 should then work.

Helpful Tip

A second, bonus tip! If you get a command not found error for croot, brunch, or lunch, be sure you’ve done the source build/envsetup.sh command in this Terminal session from the ~/android/system directory.

Helpful Tip

A third tip! If the build to fails while downloading Gello, you’ll need to import a missing certificate into Maven’s truststore. Detailed instructions on how to do that can be found here

If the build breaks…

  • If you experience this not-enough-memory-related error…
ERROR: signapk.jar failed: return code 1make: *** [out/target/product/d851/cm_d851-ota-eng.root.zip] Error 1

…you may want to make the following change to ~/android/system/build/tools/releasetools/common.py:

Search for instances of -Xmx2048m (it should appear either under OPTIONS.java_args or near usage of signapk.jar), and replace it with -Xmx1024m or -Xmx512m.

Then start the build again (with brunch).

  • If you see a message about things suddenly being “killed” for no reason, your (virtual) machine may have run out of memory or storage space. Assign it more resources and try again.

Install the build

Assuming the build completed without error (it will be obvious when it finishes), type: 

$ cd $OUT

in the same terminal window that you did the build. Here you’ll find all the files that were created. The stuff that will go in /system is in a folder called system. The stuff that will become your ramdisk is in a folder called root. And your kernel is called… kernel.

But that’s all just background info. The two files we are interested in are (1) recovery.img, which contains CyanogenMod Recovery, and (2) cm-13.0-20161224-UNOFFICIAL-d851.zip, which is the CyanogenMod installation package.

Install CyanogenMod

Back to the $OUT directory on your computer– you should see a file that looks something like: 

cm-13.0-20161224-UNOFFICIAL-d851.zip

Note:

The above file name may vary depending on the version of CM you are building. Your build may not include a version number or may identify itself as a “KANG” rather than UNOFFICIAL version. Regardless, the file name will end in .zip and should be titled similarly to official builds.

Now you can flash the cm...zip file above as usual via recovery mode. Before doing so, now is a good time to make a backup of whatever installation is currently running on the device in case something goes wrong with the flash attempt. While CyanogenMod Recovery doesn’t have a backup feature, there are other custom recoveries available that do. You can also use something like Titanium Backup (root required) as an alternative.

Success! So….what’s next?

You’ve done it! Welcome to the elite club of self-builders. You’ve built your operating system from scratch, from the ground up. You are the master/mistress of your domain… and hopefully you’ve learned a bit on the way and had some fun too.

Now that you’ve succeeded in building CyanogenMod for your device, here are some suggestions on what to do next.

Also, be sure to take a glance at the Dev Center on this wiki for all kinds of more detailed information about developer topics ranging from collecting logs, understanding what’s in the source code directories, submitting your own contributions, porting CyanogenMod to new devices, and a lot more.

How to Install CyanogenMod on the LG G2 (Verizon) (vs980)

Note: DISCLAIMER

Modifying or replacing your device’s software may void your device’s warranty, lead to data loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk. No one affiliated with the CyanogenMod project is responsible for your actions. Good luck.

Installing a custom recovery on G2 (Verizon)

The G2 (Verizon) must use a bootloader bypass enabled by the loki tools.

Before you begin, ensure you have the G2 (Verizon) USB drivers (Windows only).

  1. Download IOroot and unpack.
  2. Enable Developer Options on the device
    • Go to Settings
    • Go to About Phone
    • Tap Build Number 5 times.
  3. Enable USB Debugging on the device
    • Go to Settings
    • Go to Development Settings
    • Check USB Debugging
  4. Connect the device to your computer
  5. Open a command line/shell in your unpacked ioroot directory (or the mac subdirectory if you are running OS X)
  6. Confirm that you have a working ADB connection to the device. IOroot comes with a bundled adb executable which can be used like this:
    • Linux: ./adblinux devices (if you get permission denied, check the permissions for the device in /dev/bus/usb)
    • Windows: adb devices
    • OS X: ./adbosx devices
    • You can also use your own adb installation, but then you need to modify the root script to use it instead of the bundled one.
  7. Make sure you get and accept the RSA prompt on your device. Check Remember.
  8. Run the root script:
    • Linux/OS X: ./ioroot.sh
    • Windows: ioroot.bat
  9. Follow the on-screen instructions
  10. When the device is rooted, install FreeGee. This method might just work on stock 4.2 Android. If FreeGee gives you a device not supported error, use the AutoRec installer.
  11. Open FreeGee and tap the button to install CWM (ClockworkMod recovery) or TWRP (TeamWin Recovery Project)
  12. To reboot into recovery: open FreeGee, tap the menu button in the top right corner and select Reboot Recovery

Installing CyanogenMod from recovery

  1. Make sure your computer has working adb.
  2. Download the CyanogenMod build package for your device that you’d like to install to your computer.
    Optional: Download 3rd party applications packages, like Google Apps which are necessary to download apps from Google Play.
  3. Place the CyanogenMod .zip package, as well as any optional .zip packages, on the root of /sdcard:
    • Using adb: adb push filename.zip /sdcard/
    Note: You can copy the .zip packages to your device using any method you are familiar with. The adb method is used here because it is universal across all devices and works in both Android and recovery mode. If you are in recovery mode, you may need to ensure /sdcard (sometimes called Internal Storage) is mounted by checking its status in the Mounts menu. If you have booted regularly, USB debugging must be enabled.
  4. If you are not already in recovery, boot to recovery mode now.
    • With the device powered down, hold Volume Down & Power. When the LG logo appears release the buttons and then press them again. Then, press the Power button three times!
  5. In Team Win Recovery Project, select menu choices by tapping on the appropriately labelled button.
  6. Optional (Recommended): Select the Backup button to create a backup.
  7. Select Wipe and then Factory Reset.
  8. Select Install.
  9. Navigate to /sdcard and select the CyanogenMod .zip package.
  10. Follow the on-screen notices to install the package.
  11. Optional: Install any additional packages you wish using the same method (if you are installing multiple packages, install CyanogenMod first and then install any subsequent packages on top of it).
  12. Once installation has finished, return to the main menu and select Reboot, then System. The device will now boot into CyanogenMod.

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

Initialize the CyanogenMod source repository

Enter the following to initialize the repository:

Note: Make sure the cm branch entered here is the one you wish to build and is supported on your device.
$ cd ~/android/system/
$ repo init -u https://github.com/CyanogenMod/android.git -b cm-13.0

Download the source code

To start the download of all the source code to your computer: 

$ repo sync

The CM manifests include a sensible default configuration for repo, which we strongly suggest you use (i.e. don’t add any options to sync). For reference, our default values are -j 4 and -c. The -j 4 part means that there will be four simultaneous threads/connections. If you experience problems syncing, you can lower this to -j 3 or -j 2. -c will ask repo to pull in only the current branch, instead of the entire CM history.

Prepare to wait a long time while the source code downloads.

Helpful Tip

The repo sync command is used to update the latest source code from CyanogenMod and Google. Remember it, as you can do it every few days to keep your code base fresh and up-to-date.

Get prebuilt apps (CM11 and below)

Next, 

$ cd ~/android/system/vendor/cm

then enter: 

$ ./get-prebuilts

You won’t see any confirmation- just another prompt. But this should cause some prebuilt apps to be loaded and installed into the source code. Once completed, this does not need to be done again.

Prepare the device-specific code

Helpful Tip – Errors during breakfast

Different maintainers setup their device inheritance rules differently. Some require a vendor directory to be populated before breakfast will even succeed. If you receive an error here about vendor makefiles, then jump down to the next section Extract proprietary blobs. The first portion of breakfast should have succeeded at pulling in the device tree and the extract blobs script should be available. After completing that section, you can rerun breakfast vs980

After the source downloads, ensure you are in the root of the source code (cd ~/android/system), then type: 

$ source build/envsetup.sh
$ breakfast vs980

This will download the device specific configuration and kernel source for your device. An alternative to using the breakfast command is to build your own local manifest. To do this, you will need to locate your device on CyanogenMod’s GitHub and list all of the repositories defined in cm.dependencies in your local manifest.

Helpful Tip

If you want to know more about what source build/envsetup.sh does or simply want to know more about the breakfast, brunch and lunch commands, you can head over to the Envsetup help page.

Helpful Tip

Instead of typing cd ~/android/system every time you want to return back to the root of the source code, here’s a short command that will do it for you: croot. To use this command, you must first run source build/envsetup.sh from ~/android/system.

Extract proprietary blobs

Now ensure that your G2 (Verizon) is connected to your computer via the USB cable and that you are in the ~/android/system/device/lge/vs980 directory (you can cd ~/android/system/device/lge/vs980 if necessary). Then run the extract-files.sh script: 

$ ./extract-files.sh

You should see the proprietary files (aka “blobs”) get pulled from the device and moved to the ~/android/system/vendor/lge directory. If you see errors about adb being unable to pull the files, adb may not be in the path of execution. If this is the case, see the adb page for suggestions for dealing with “command not found” errors.

Note:

Your device should already be running a build of CyanogenMod for the branch you wish to build for the extract-files.sh script to function properly.

Note:

It’s important that these proprietary files are extracted to the ~/android/system/vendor/lge directory by using the extract-files.sh script. Makefiles are generated at the same time to make sure the blobs are eventually copied to the device. Without these blobs, CyanogenMod may build without error, but you’ll be missing important functionality, such as graphics libraries that enable you to see anything!

Turn on caching to speed up build

You can speed up subsequent builds by adding 

export USE_CCACHE=1

to your ~/.bashrc file (what’s a .bashrc file?). Then, specify the amount of disk space to dedicate to ccache by typing this from the top of your Android tree: 

prebuilts/misc/linux-x86/ccache/ccache -M 50G

where 50G corresponds to 50GB of cache. This only needs to be run once and the setting will be remembered. Anywhere in the range of 25GB to 100GB will result in very noticeably increased build speeds (for instance, a typical 1hr build time can be reduced to 20min). If you’re only building for one device, 25GB-50GB is fine. If you plan to build for several devices that do not share the same kernel source, aim for 75GB-100GB. This space will be permanently occupied on your drive, so take this into consideration. See more information about ccache on Google’s android build environment initialization page.

Helpful Tip

If you are a very active developer, working on many other projects than just Android, you might prefer to keep your Android ccache independent (because it’s huge and can slow down the efficiency of ccache in your other projects). Beginning with CyanogenMod 12.1, you can specify environment variables for the location and size of CyanogenMod’s ccache. Some syntax examples: export ANDROID_CCACHE_DIR="$HOME/android/.ccache" and export ANDROID_CCACHE_SIZE="50G".

Start the build

Time to start building! So now type: 

$ croot
$ brunch vs980

The build should begin.

Helpful Tip

If the build doesn’t start, try lunch and choose your device from the menu. If that doesn’t work, try breakfast and choose from the menu. The command make vs980 should then work.

Helpful Tip

A second, bonus tip! If you get a command not found error for croot, brunch, or lunch, be sure you’ve done the source build/envsetup.sh command in this Terminal session from the ~/android/system directory.

Helpful Tip

A third tip! If the build to fails while downloading Gello, you’ll need to import a missing certificate into Maven’s truststore. Detailed instructions on how to do that can be found here

If the build breaks…

  • If you experience this not-enough-memory-related error…
ERROR: signapk.jar failed: return code 1make: *** [out/target/product/vs980/cm_vs980-ota-eng.root.zip] Error 1

…you may want to make the following change to ~/android/system/build/tools/releasetools/common.py:

Search for instances of -Xmx2048m (it should appear either under OPTIONS.java_args or near usage of signapk.jar), and replace it with -Xmx1024m or -Xmx512m.

Then start the build again (with brunch).

  • If you see a message about things suddenly being “killed” for no reason, your (virtual) machine may have run out of memory or storage space. Assign it more resources and try again.

Install the build

Assuming the build completed without error (it will be obvious when it finishes), type: 

$ cd $OUT

in the same terminal window that you did the build. Here you’ll find all the files that were created. The stuff that will go in /system is in a folder called system. The stuff that will become your ramdisk is in a folder called root. And your kernel is called… kernel.

But that’s all just background info. The two files we are interested in are (1) recovery.img, which contains CyanogenMod Recovery, and (2) cm-13.0-20161224-UNOFFICIAL-vs980.zip, which is the CyanogenMod installation package.

Install CyanogenMod

Back to the $OUT directory on your computer– you should see a file that looks something like: 

cm-13.0-20161224-UNOFFICIAL-vs980.zip

Note:

The above file name may vary depending on the version of CM you are building. Your build may not include a version number or may identify itself as a “KANG” rather than UNOFFICIAL version. Regardless, the file name will end in .zip and should be titled similarly to official builds.

Now you can flash the cm...zip file above as usual via recovery mode. Before doing so, now is a good time to make a backup of whatever installation is currently running on the device in case something goes wrong with the flash attempt. While CyanogenMod Recovery doesn’t have a backup feature, there are other custom recoveries available that do. You can also use something like Titanium Backup (root required) as an alternative.

Success! So….what’s next?

You’ve done it! Welcome to the elite club of self-builders. You’ve built your operating system from scratch, from the ground up. You are the master/mistress of your domain… and hopefully you’ve learned a bit on the way and had some fun too.

Now that you’ve succeeded in building CyanogenMod for your device, here are some suggestions on what to do next.

Also, be sure to take a glance at the Dev Center on this wiki for all kinds of more detailed information about developer topics ranging from collecting logs, understanding what’s in the source code directories, submitting your own contributions, porting CyanogenMod to new devices, and a lot more.

Congrats again!

How to Install CyanogenMod on the Samsung Galaxy Note 2 LTE (t0lte)

Note: DISCLAIMER

Modifying or replacing your device’s software may void your device’s warranty, lead to data loss, hair loss, financial loss, privacy loss, security breaches, or other damage, and therefore must be done entirely at your own risk. No one affiliated with the CyanogenMod project is responsible for your actions. Good luck.

Installing a custom recovery

Samsung devices come with a unique boot mode called Download Mode which is very similar to Fastboot Mode on some devices with unlocked bootloaders. Heimdall is a cross-platform, open source tool for interfacing with Download Mode on Samsung devices. The preferred method of installing a custom recovery is through this boot mode. Rooting the stock firmware is neither recommended nor necessary.

  1. Download and install the Heimdall Suite
    • Windows: Extract the Heimdall suite and take note of the directory holding heimdall.exe. You can verify Heimdall is working by opening a command prompt in this directory and typing heimdall version. If you receive an error, be sure that you have the Microsoft Visual C++ 2012 Redistributable Package (x86/32bit) installed on your computer.
    • Linux: Pick the appropriate installation package based on your distribution. The -frontend packages are not required for this guide. After installation, heimdall should be available from the terminal; type heimdall version to verify installation succeeded.
    • Mac: Install the dmg package. After installation, heimdall should be available from the terminal; type heimdall version to verify installation succeeded.
    • Building from source: The source code for the Heimdall Suite is available on Github. For more details about how to compile the Heimdall Suite, please refer to the README file on Github under the relevant operating system directory. You can also refer to the Install and compile Heimdall instructions on this wiki.
  2. Download recovery — you can directly download a recovery image using the link below, or visit TWRP site to check for the latest version of recovery for your device (if your device can be found there). For general info about recoveries click here.
    Recovery: Download
    md5: 9ec2a04750c86d0f2dbcdd2264933036
  3. Power off the Galaxy Note 2 LTE and connect the USB adapter to the computer but not to the Galaxy Note 2 LTE, yet.
  4. Boot the Galaxy Note 2 LTE into download mode. Home & Volume Down & Power Accept the disclaimer on the device. Then, insert the USB cable into the device.
  5. Windows (only) driver installation – Skip this step if you are using Linux or Mac
    A more complete set of the following instructions can be found in the Zadig User Guide.
    1. Run zadig.exe from the Drivers folder of the Heimdall Suite.
    2. Choose Options » List All Devices from the menu.
    3. Select Samsung USB Composite Device or MSM8x60 or Gadget Serial or Device Name from the drop down menu. (If nothing relevant appears, try uninstalling any Samsung related Windows software, like Samsung Windows drivers and/or Kies).
    4. Click Replace Driver (having selecting “Install Driver” from the drop down list built into the button).
    5. If you are prompted with a warning that the installer is unable to verify the publisher of the driver, select Install this driver anyway. You may receive two more prompts about security. Select the options that allow you to carry on.
  6. At this point, familiarize yourself with the Flashing with heimdall notes below so that you are prepared for any strange behaviour if it occurs.
  7. On the computer, open a terminal (or Command Prompt on Windows) in the directory where the recovery image is located and type:
    heimdall flash --RECOVERY recovery.img --no-reboot
    Tip: The file may not be named identically to what’s in this command. If the file is wrapped in a zip or tar file, extract the file first, because heimdall isn’t going to do it for you.
  8. A blue transfer bar will appear on the device showing the recovery being transferred.
  9. Unplug the USB cable from your device.
    • NOTE: Be sure to reboot into recovery immediately after having installed the custom recovery. Otherwise the custom recovery will be overwritten and the device will reboot (appearing as though your custom recovery failed to install).
  10. Manually reboot the phone into recovery mode by performing the following. Home & Volume Up & Power
  11. The Galaxy Note 2 LTE now has a custom recovery installed. Continue to the next section.

Note: Flashing with heimdall

  • In Windows 7 UAC (User Account Control) may need switching off. Once Heimdall is finished it can be re-enabled.
  • Protocol initialization can fail if the device is connected via a USB hub – connect the USB cable directly to the PC
  • It may be necessary to run the heimdall flash command as root in Linux or Mac OS X: sudo heimdall flash [...]. Typical symptoms of this are:
    • a blue bar doesn’t show up after the process has finished
    • Failed to confirm end of file transfer sequence!
  • It may be necessary to capitalize the name of the partition on some devices. Try --KERNEL instead of --kernel and/or --recovery instead of --RECOVERY.
  • If on Linux 64bit you get “unable to execute ./heimdall: No such file or directory”, try the 32bit version and make sure to run it with sudo: reference.
  • On Mac OS X you may see this message: “ERROR: Claiming interface failed!”. If so, you need to disable the default USB drivers with the following commands:
    sudo kextunload -b com.apple.driver.AppleUSBCDC;
    sudo kextunload -b com.apple.driver.AppleUSBCDCACMControl;
    sudo kextunload -b com.apple.driver.AppleUSBCDCACMData;
    If you have installed Samsung Kies, you may further need to unload those USB drivers with the following commands:
    sudo kextunload -b com.devguru.driver.SamsungComposite;
    sudo kextunload -b com.devguru.driver.SamsungACMData
    sudo kextunload -b com.devguru.driver.SamsungACMControl
  • Using Heimdall version 1.4.0 (the latest version available for download on the Glass Echidna website) you may see this message or one similar to it:
    Error: Failed to confirm end of PIT file transfer!
    If you experience this error, follow the instructions for compiling Heimdall from source to get the latest version on GitHub with the issue patched.

Helpful Tip

  • The stock ROM may overwrite your custom recovery on boot. To prevent this, boot immediately into recovery after leaving Download Mode instead of letting the ROM boot up normally. If your recovery is overwritten, simply redo the steps you followed above and catch it before it boots next time.
  • Note for upgrades from gingerbread to jellybean remember the recovery is changed. This means once you install do NOT restore to old-gingerbread-stock ROM from cwm-recovery.
  • To upgrade from stock/CM7/CM9/CM10.1.2/CM10.1.3 to CM10.2, you must first boot into recovery and wipe data, cache, and dalvik cache (factory reset). Due to the new partition layout in CM10.2, failing to perform these steps will result in a bootloop. See here for details; more about repartitioning here. If you missed this step before installing, boot to recovery and factory reset, then reinstall CM10.2.
  • Some users have reported connection errors if the device is connected to a USB hub. If you experience such errors it is recommended that you try connecting your device to a USB port on the motherboard.
  • Antivirus software may prevent Heimdall from connecting properly. Disable your antivirus before proceeding.
  • When Heimdall fails to connect, the Download mode may get stuck, making all further attempts fail too. To retry, you may need to restart the Download mode: turn off the phone by holding Power for 5-10 seconds (or by pulling out the battery), then boot into Download mode and run Heimdall again.
  • If Heimdall fails to connect (errors related to initializing the protocol, or transferring data):
    if you just installed the driver, try rebooting your computer and trying again.
    if you still have troubles after reboot, in Zadig try installing the libusbK driver rather than the WinUSB driver.

Installing CyanogenMod from recovery

  1. Make sure your computer has working adb.
  2. Download the CyanogenMod build package for your device that you’d like to install to your computer.
    Optional: Download 3rd party applications packages, like Google Apps which are necessary to download apps from Google Play.
  3. Place the CyanogenMod .zip package, as well as any optional .zip packages, on the root of /sdcard:
    • Using adb: adb push filename.zip /sdcard/
    Note: You can copy the .zip packages to your device using any method you are familiar with. The adb method is used here because it is universal across all devices and works in both Android and recovery mode. If you are in recovery mode, you may need to ensure /sdcard (sometimes called Internal Storage) is mounted by checking its status in the Mounts menu. If you have booted regularly, USB debugging must be enabled.
  4. If you are not already in recovery, boot to recovery mode now.
    • Home & Volume Up & Power
  5. In Team Win Recovery Project, select menu choices by tapping on the appropriately labelled button.
  6. Optional (Recommended): Select the Backup button to create a backup.
  7. Select Wipe and then Factory Reset.
  8. Select Install.
  9. Navigate to /sdcard and select the CyanogenMod .zip package.
  10. Follow the on-screen notices to install the package.
  11. Optional: Install any additional packages you wish using the same method (if you are installing multiple packages, install CyanogenMod first and then install any subsequent packages on top of it).
  12. Once installation has finished, return to the main menu and select Reboot, then System. The device will now boot into CyanogenMod.

How To Build CyanogenMod For Samsung Galaxy Note 2 LTE (t0lte)

Introduction

These instructions will hopefully assist you to start with a stock Galaxy Note 2 LTE, unlock the bootloader (if necessary), and then download the required tools as well as the very latest source code for CyanogenMod (based on Google’s Android operating system). Using these, you can build both CyanogenMod and CyanogenMod Recovery image from source code, and then install them both to your device.

It is difficult to say how much experience is necessary to follow these instructions. While this guide is certainly not for the very very very uninitiated, these steps shouldn’t require a PhD in software development either. Some readers will have no difficulty and breeze through the steps easily. Others may struggle over the most basic operation. Because people’s experiences, backgrounds, and intuitions differ, it may be a good idea to read through just to ascertain whether you feel comfortable or are getting over your head.

Remember, you assume all risk of trying this, but you will reap the rewards! It’s pretty satisfying to boot into a fresh operating system you baked at home :) And once you’re an Android-building ninja, there will be no more need to wait for “nightly” builds from anyone. You will have at your fingertips the skills to build a full operating system from code to a running device, whenever you want. Where you go from there– maybe you’ll add a feature, fix a bug, add a translation, or use what you’ve learned to build a new app or port to a new device– or maybe you’ll never build again– it’s all really up to you.

What you’ll need

  • A Galaxy Note 2 LTE
  • A relatively recent computer (Linux, OS X, or Windows) with a reasonable amount of RAM and about 100 GB of free storage (more if you enable ccache or build for multiple devices). The less RAM you have, the longer the build will take (aim for 8 GB or more). Using SSDs results in considerably faster build times than traditional hard drives.
  • A USB cable compatible with the Galaxy Note 2 LTE (typically micro USB, but older devices may use mini USB or have a proprietary cable)
  • A decent internet connection & reliable electricity :)
  • Some familiarity with basic Android operation and terminology. It would help if you’ve installed custom roms on other devices and are familiar with recovery. It may also be useful to know some basic command line concepts such as cd for “change directory”, the concept of directory hierarchies, that in Linux they are separated by /, etc.

If you are not accustomed to using Linux– this is an excellent chance to learn. It’s free– just download and run a virtual machine (VM) such as Virtualbox, then install a Linux distribution such as Ubuntu (AOSP vets Ubuntu as well). Any recent 64-bit version should work great, but the latest is recommended.

Note:

You want to use a 64-bit version of Linux. A 32-bit Linux environment will only work if you are building CyanogenMod 6 and older. For CyanogenMod 10.1, if you encounter issues with 64bit host binaries, you can set BUILD_HOST_32bit=1 in your environment. This is generally not needed, though, especially with CyanogenMod 10.2 and newer.

Using a VM allows Linux to run as a guest inside your host computer– a computer in a computer, if you will. If you hate Linux for whatever reason, you can always just uninstall and delete the whole thing. (There are plenty of places to find instructions for setting up Virtualbox with Ubuntu, so I’ll leave it to you to do that.)

So let’s begin!

Build CyanogenMod and CyanogenMod Recovery

Prepare the Build Environment

Note:

You only need to do these steps the first time you build. If you previously prepared your build environment and have downloaded the CyanogenMod source code for another device, skip to Prepare the device-specific code.

Install the SDK

If you have not previously installed adb and fastboot, install the Android SDK. “SDK” stands for Software Developer Kit, and it includes useful tools that you can use to flash software, look at the system logs in real time, grab screenshots, and more– all from your computer.

Helpful Tip

While the SDK contains lots of different things– the two tools you are most interested in for building Android are adb and fastboot, located in the /platform-tools directory.

Install the Build Packages

Several “build packages” are needed to build CyanogenMod. You can install these using the package manager of your choice.

Helpful Tip

A package manager in Linux is a system used to install or remove software (usually originating from the Internet) on your computer. With Ubuntu, you can use the Ubuntu Software Center. Even better, you may also use the apt-get install command directly in the Terminal. (Learn more about the apt packaging tool system from Wikipedia.)

For both 32-bit & 64-bit systems, you’ll need: 

bc bison build-essential curl flex git gnupg gperf libesd0-dev liblz4-tool libncurses5-dev libsdl1.2-dev libwxgtk2.8-dev libxml2 libxml2-utils lzop maven openjdk-7-jdk pngcrush schedtool squashfs-tools xsltproc zip zlib1g-dev

In addition to the above, for 64-bit systems, get these: 

g++-multilib gcc-multilib lib32ncurses5-dev lib32readline-gplv2-dev lib32z1-dev

For Ubuntu 15.10 (wily) and newer, substitute:

  • lib32readline-gplv2-dev → lib32readline6-dev

For Ubuntu 16.04 (xenial) and newer, substitute (additionally see java notes below):

  • libwxgtk2.8-dev → libwxgtk3.0-dev
  • openjdk-7-jdk → openjdk-8-jdk

Java versions: Different versions of CyanogenMod require different versions of the JDK (Java Development Kit):

  • CyanogenMod 7 – 9: Sun/Oracle Java SE 1.6
  • CyanogenMod 10.1: Sun/Oracle Java SE 1.6 or 1.7
  • CyanogenMod 10.2 – 11.0: Sun/Oracle Java SE 1.6 or 1.7 (OpenJDK 1.7 works fine, but the build system will display a warning)
  • CyanogenMod 12.0 – 13.0: OpenJDK 1.7 (see note about OpenJDK 1.8 below)
  • CyanogenMod 14.1: OpenJDK 1.8

Ubuntu 16.04 (Xenial Xerus) or newer and OpenJDK: Since OpenJDK 1.7 was removed from the official Ubuntu repositories, you have a couple options:

  1. Obtain OpenJDK 1.7 from the openjdk-r PPA
  2. Enable experimental OpenJDK 1.8 support in CyanogenMod 13.0 (not available in earlier version). To enable OpenJDK 1.8 support, add this line to your $HOME/.bashrc file: export EXPERIMENTAL_USE_JAVA8=true.

Also see http://source.android.com/source/initializing.html which lists needed packages.

Create the directories

You will need to set up some directories in your build environment.

To create them: 

$ mkdir -p ~/bin
$ mkdir -p ~/android/system

Install the repo command

Enter the following to download the “repo” binary and make it executable (runnable): 

$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
$ chmod a+x ~/bin/repo

Put the ~/bin directory in your path of execution

In recent versions of Ubuntu, ~/bin should already be in your PATH. You can check this by opening ~/.profile with a text editor and verifying the following code exists (add it if it is missing): 

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

Initialize the CyanogenMod source repository

Enter the following to initialize the repository:

Note: Make sure the cm branch entered here is the one you wish to build and is supported on your device.
$ cd ~/android/system/
$ repo init -u https://github.com/CyanogenMod/android.git -b cm-13.0

Download the source code

To start the download of all the source code to your computer: 

$ repo sync

The CM manifests include a sensible default configuration for repo, which we strongly suggest you use (i.e. don’t add any options to sync). For reference, our default values are -j 4 and -c. The -j 4 part means that there will be four simultaneous threads/connections. If you experience problems syncing, you can lower this to -j 3 or -j 2. -c will ask repo to pull in only the current branch, instead of the entire CM history.

Prepare to wait a long time while the source code downloads.

Helpful Tip

The repo sync command is used to update the latest source code from CyanogenMod and Google. Remember it, as you can do it every few days to keep your code base fresh and up-to-date.

Get prebuilt apps (CM11 and below)

Next, 

$ cd ~/android/system/vendor/cm

then enter: 

$ ./get-prebuilts

You won’t see any confirmation- just another prompt. But this should cause some prebuilt apps to be loaded and installed into the source code. Once completed, this does not need to be done again.

Prepare the device-specific code

Helpful Tip – Errors during breakfast

Different maintainers setup their device inheritance rules differently. Some require a vendor directory to be populated before breakfast will even succeed. If you receive an error here about vendor makefiles, then jump down to the next section Extract proprietary blobs. The first portion of breakfast should have succeeded at pulling in the device tree and the extract blobs script should be available. After completing that section, you can rerun breakfast t0lte

After the source downloads, ensure you are in the root of the source code (cd ~/android/system), then type: 

$ source build/envsetup.sh
$ breakfast t0lte

This will download the device specific configuration and kernel source for your device. An alternative to using the breakfast command is to build your own local manifest. To do this, you will need to locate your device on CyanogenMod’s GitHub and list all of the repositories defined in cm.dependencies in your local manifest.

Helpful Tip

If you want to know more about what source build/envsetup.sh does or simply want to know more about the breakfast, brunch and lunch commands, you can head over to the Envsetup help page.

Helpful Tip

Instead of typing cd ~/android/system every time you want to return back to the root of the source code, here’s a short command that will do it for you: croot. To use this command, you must first run source build/envsetup.sh from ~/android/system.

Extract proprietary blobs

Now ensure that your Galaxy Note 2 LTE is connected to your computer via the USB cable and that you are in the ~/android/system/device/samsung/t0lte directory (you can cd ~/android/system/device/samsung/t0lte if necessary). Then run the extract-files.sh script: 

$ ./extract-files.sh

You should see the proprietary files (aka “blobs”) get pulled from the device and moved to the ~/android/system/vendor/samsung directory. If you see errors about adb being unable to pull the files, adb may not be in the path of execution. If this is the case, see the adb page for suggestions for dealing with “command not found” errors.

Note:

Your device should already be running a build of CyanogenMod for the branch you wish to build for the extract-files.sh script to function properly.

Note:

It’s important that these proprietary files are extracted to the ~/android/system/vendor/samsung directory by using the extract-files.sh script. Makefiles are generated at the same time to make sure the blobs are eventually copied to the device. Without these blobs, CyanogenMod may build without error, but you’ll be missing important functionality, such as graphics libraries that enable you to see anything!

Turn on caching to speed up build

You can speed up subsequent builds by adding 

export USE_CCACHE=1

to your ~/.bashrc file (what’s a .bashrc file?). Then, specify the amount of disk space to dedicate to ccache by typing this from the top of your Android tree: 

prebuilts/misc/linux-x86/ccache/ccache -M 50G

where 50G corresponds to 50GB of cache. This only needs to be run once and the setting will be remembered. Anywhere in the range of 25GB to 100GB will result in very noticeably increased build speeds (for instance, a typical 1hr build time can be reduced to 20min). If you’re only building for one device, 25GB-50GB is fine. If you plan to build for several devices that do not share the same kernel source, aim for 75GB-100GB. This space will be permanently occupied on your drive, so take this into consideration. See more information about ccache on Google’s android build environment initialization page.

Helpful Tip

If you are a very active developer, working on many other projects than just Android, you might prefer to keep your Android ccache independent (because it’s huge and can slow down the efficiency of ccache in your other projects). Beginning with CyanogenMod 12.1, you can specify environment variables for the location and size of CyanogenMod’s ccache. Some syntax examples: export ANDROID_CCACHE_DIR="$HOME/android/.ccache" and export ANDROID_CCACHE_SIZE="50G".

Start the build

Time to start building! So now type: 

$ croot
$ brunch t0lte

The build should begin.

Helpful Tip

If the build doesn’t start, try lunch and choose your device from the menu. If that doesn’t work, try breakfast and choose from the menu. The command make t0lte should then work.

Helpful Tip

A second, bonus tip! If you get a command not found error for croot, brunch, or lunch, be sure you’ve done the source build/envsetup.sh command in this Terminal session from the ~/android/system directory.

Helpful Tip

A third tip! If the build to fails while downloading Gello, you’ll need to import a missing certificate into Maven’s truststore. Detailed instructions on how to do that can be found here

If the build breaks…

  • If you experience this not-enough-memory-related error…
ERROR: signapk.jar failed: return code 1make: *** [out/target/product/t0lte/cm_t0lte-ota-eng.root.zip] Error 1

…you may want to make the following change to ~/android/system/build/tools/releasetools/common.py:

Search for instances of -Xmx2048m (it should appear either under OPTIONS.java_args or near usage of signapk.jar), and replace it with -Xmx1024m or -Xmx512m.

Then start the build again (with brunch).

  • If you see a message about things suddenly being “killed” for no reason, your (virtual) machine may have run out of memory or storage space. Assign it more resources and try again.

Install the build

Assuming the build completed without error (it will be obvious when it finishes), type: 

$ cd $OUT

in the same terminal window that you did the build. Here you’ll find all the files that were created. The stuff that will go in /system is in a folder called system. The stuff that will become your ramdisk is in a folder called root. And your kernel is called… kernel.

But that’s all just background info. The two files we are interested in are (1) recovery.img, which contains CyanogenMod Recovery, and (2) cm-13.0-20161224-UNOFFICIAL-t0lte.zip, which is the CyanogenMod installation package.

Install CyanogenMod

Back to the $OUT directory on your computer– you should see a file that looks something like: 

cm-13.0-20161224-UNOFFICIAL-t0lte.zip

Note:

The above file name may vary depending on the version of CM you are building. Your build may not include a version number or may identify itself as a “KANG” rather than UNOFFICIAL version. Regardless, the file name will end in .zip and should be titled similarly to official builds.

Now you can flash the cm...zip file above as usual via recovery mode. Before doing so, now is a good time to make a backup of whatever installation is currently running on the device in case something goes wrong with the flash attempt. While CyanogenMod Recovery doesn’t have a backup feature, there are other custom recoveries available that do. You can also use something like Titanium Backup (root required) as an alternative.

Success! So….what’s next?

You’ve done it! Welcome to the elite club of self-builders. You’ve built your operating system from scratch, from the ground up. You are the master/mistress of your domain… and hopefully you’ve learned a bit on the way and had some fun too.

Now that you’ve succeeded in building CyanogenMod for your device, here are some suggestions on what to do next.

Also, be sure to take a glance at the Dev Center on this wiki for all kinds of more detailed information about developer topics ranging from collecting logs, understanding what’s in the source code directories, submitting your own contributions, porting CyanogenMod to new devices, and a lot more.

Congrats again!
