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 one here.

  2. Place the recovery image file on the root of /sdcard:
    • Using adb: adb push <recovery_filename>.img /sdcard/<recovery_filename>.img
    • 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/<recovery_filename>.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. Build a LineageOS install package.

    • Optionally, download additional 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. Now tap Wipe.
  4. 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.

  5. Return to the previous menu and tap Advanced Wipe, then select the Cache and System partitions to be wiped and then Swipe to Wipe.

  6. Sideload the LineageOS .zip package:
    • On the device, select “Advanced”, “ADB Sideload”, then swipe to begin sideload.
    • On the host machine, sideload the package using: adb sideload filename.zip
  7. (Optionally): If you want to install any additional add-ons, adb sideload /path/to/zip those packages in sequence.

  8. (Optional): Root the device by installing the LineageOS’s AddonSU, (use the arm package) or using any other method you prefer.
  9. Once all installations are finished, run ‘adb reboot’.
