Install LineageOS on d803

Basic requirements

  1. Make sure your computer has 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 Lineage Recovery. Simply download the latest recovery file, named something like lineage-16.0-20190914-recovery-d803.img.

  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. Then answer YES to erase all user data & restore default settings (If you have TWRP installed it will not delete anything).

Installing LineageOS from recovery

  1. Download the LineageOS installation package that you would like to install or build the package yourself.

    • Optionally, download additional application packages such as Google Apps (use the arm64 architecture).
  2. If you are not 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. Then answer YES to erase all user data & restore default settings (If you have TWRP installed it will not delete anything).
  3. Now tap Factory Reset, then Wipe data / factory reset and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage, as well as format your cache partition (if you have one).
  4. Now tap Wipe System and continue with the formatting process.
  5. Return to the main menu.
  6. Sideload the LineageOS .zip package:
    • On the device, select “Apply Update”, then “Apply from ADB” 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 filename.zip those packages in sequence.

  8. (Optional): Root your device by installing LineageOS’ AddonSU, (use the arm64 package) or by using any other method you prefer.
  9. Once you have installed everything successfully, run ‘adb reboot’.
