How to Install CyanogenMod on the LG G2 (AT&T) ("d800")

This guide will walk you through the process of taking the G2 (AT&T) from stock to having a custom recovery image and the ability to flash the latest version of CyanogenMod.

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 (AT&T)

The G2 (AT&T) must use a bootloader bypass enabled by the loki tools.

Before you begin, ensure you have the G2 (AT&T) 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: ./adb devices (if you get permission denied, check the permissions for the device in /dev/bus/usb)
   • Windows: adb devices
   • OS X: ./adb 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: ./root.sh
   • Windows: root.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. Download the CyanogenMod 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.

2. Boot to recovery mode, and connect the phone to your computer through USB.
   • 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!
3. In ClockworkMod Recovery, use the physical volume buttons to move up and down. On most devices, the power button is used to confirm a menu selection, but for some devices a physical home key acts as a selector. Some devices have touch enabled ClockworkMod Recovery, in which case you may be able to swipe to, or touch, menu selections.
4. Optional (Recommended): Select backup and restore to create a backup of your current ROM.
5. Select wipe data/factory reset.
6. You have two options for transferring and installing the installation packages. Both cases require adb to be working in recovery. The sideload method is more universal across devices, whereas the push and install method is more commonly used:
   • Sideload method: select install zip > install zip from sideload. Follow the on-screen notices to install the package. The installer does not necessarily display an "Install complete." message. You can tell the install is complete if there were no fatal error messages and you have regained control over the menu.
   • Push and install method: Open a command prompt (or Terminal on Mac and Linux) and navigate to the directory holding the package(s) you would like to install. On the device, navigate to the mounts and storage menu. If you see /storage/sdcard0 or /sdcard as a mountable volume, go ahead and mount it. If you do not see one of these partitions, then instead mount the /data partition. Take note of which volume you mounted. Now, push the package(s) to your device (also, see tip below):

   - If you mounted /storage/sdcard0, then: adb push update.zip /storage/sdcard0/

   - If you mounted /sdcard or /data, then: adb push update.zip /sdcard/

   where update.zip should be replaced with the package filename. Go back to the main menu and select install zip. Choose to install from the same directory where you pushed the package(s). If you are installing multiple packages, install CyanogenMod first and then install any subsequent packages on top of it.

7. Once installation has finished, return to the main menu and select reboot system now. The device will now boot into CyanogenMod.

Helpful Tip– SD card folders

CyanogenMod 10.1 and newer have multi-user support (introduced in Android 4.2). If your device has storage on the /data partition, then Android actually looks in /data/media/0/ for the first user's /sdcard/ storage. ClockworkMod recovery symlinks /sdcard/ to /data/media/ though. So, if you are pushing files to internal storage in recovery and want them to be visible in Android, you should push them to /sdcard/0/ or /data/media/0/. Here's the most frequent scenarios:

1. If you're coming from a ROM with Android 4.1 or older to CyanogenMod 10 or older: adb push update.zip /sdcard/
2. If you're coming from a ROM with Android 4.1 or older to CyanogenMod 10.1 or newer: adb shell "mkdir /sdcard/0/" followed by adb push update.zip /sdcard/0/
3. If you're coming from a ROM with Android 4.2 or newer to CyanogenMod 10.1 or newer: adb push update.zip /sdcard/0/
