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. Simply search for your device on that page and download the latest recovery file, named something like twrp-x.x.x-x-g2m.img.
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’s 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 down, hold Volume Down & Power. When the LG logo appears release the buttons and then hold them down 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
2. 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.
3. If you aren’t already in recovery, reboot into recovery:
   • With the device powered down, hold Volume Down & Power. When the LG logo appears release the buttons and then hold them down again. Choose ‘Yes’ twice to confirm.
4. (Optional, but recommended): Select the Backup button to create a backup.
5. Select Wipe and then Advanced Wipe.
6. Select Cache, System and Data partitions to be wiped and then Swipe to Wipe.
7. Go back to return to main menu, then select Install.
8. Navigate to /sdcard, and select the LineageOS .zip package.
9. Follow the on-screen prompts to install the package.
10. (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 reboot!
11. (Optional): Root the device by installing the LineageOS su add-on (use the arm package) or using any other method you prefer.
12. Once installation has finished, return to the main menu, select Reboot, and then System.
