Install LineageOS on g2m

Basic requirements

1. Make sure your computer has working adb. Setup instructions can be found here.
2. Enable USB debugging on your device.

Rooting your device

1. Root your device by following this guide.

Installing a custom recovery using dd

1. Download a custom recovery - you can download TWRP.

2. Place the recovery image file on the root of /sdcard:
   • Using adb: adb push twrp-x.x.x-x-g2m.img /sdcard/twrp-g2m.img
   Tip: The file may not be named identically to what stands in this command, so adjust accordingly.
   • You can use any method you are comfortable with. adb is universal across all devices, and works both in Android and recovery mode, providing USB debugging is enabled.
3. Now, open an adb shell from a command prompt (on Windows) or terminal (on Linux or macOS) window. In that shell, type the following commands:

   su
   dd if=/sdcard/twrp-g2m.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
   

4. Manually reboot into recovery:
   • With the device powered off, hold Volume Down + Power. When the LG logo appears, release both buttons and then hold them again. Choose ‘Yes’ twice to confirm.

Installing LineageOS from recovery

1. Download the LineageOS install package that you’d like to install or build the package yourself.

   • Optionally, download 3rd party application packages such as Google Apps (use the arm architecture)
2. If you aren’t already in recovery, reboot into recovery:
   • With the device powered off, hold Volume Down + Power. When the LG logo appears, release both buttons and then hold them again. Choose ‘Yes’ twice to confirm.
3. (Optional, but recommended): Tap the Backup button to create a backup. Make sure the backup is created in the external sdcard or copy it onto your computer as the internal storage will be formatted.
4. Go back to return to main menu, then tap Wipe.
5. Now tap Format Data and continue with the formatting process. This will remove encryption as well as delete all files stored on the internal storage.

6. Return to the previous menu and tap Advanced Wipe.

7. Select the Cache and System partitions to be wiped and then Swipe to Wipe.

8. Place the LineageOS .zip package, as well as any other .zip packages on the root of /sdcard:
   • Using adb: adb push filename.zip /sdcard/
   • You can use any method you are comfortable with. adb is universal across all devices, and works both in Android and recovery mode, providing USB debugging is enabled.
9. Go back to return to main menu, then tap Install.
10. Navigate to /sdcard, and select the LineageOS .zip package.

11. Follow the on-screen prompts to install the package.

12. (Optional): Install any additional packages using the same method.

    Note: If you want any Google Apps on your device, you must follow this step before the first boot into Android!
13. (Optional): Root the device by installing the LineageOS su add-on (use the arm package) or using any other method you prefer.
14. Once installation has finished, return to the main menu, tap Reboot, and then System.
