Terminology

What you need to know

Basic requirements

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

Installing a custom recovery using fastboot

  1. Download a custom recovery - you can download TWRP. Simply download the latest recovery file, named something like twrp-x.x.x-x-wt88047.img.

  2. Connect your device to your PC via USB.
  3. On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
    adb reboot bootloader
    

    You can also boot into fastboot mode via a key combination:

    • With the device powered off, hold Volume Down + Power.
  4. Once the device is in fastboot mode, verify your PC finds it by typing:
    fastboot devices
    
  5. Flash recovery onto your device:
    fastboot flash recovery <recovery_filename>.img
    
  6. Now reboot into recovery to verify the installation:
    • With the device powered off, hold Volume Up + Volume Down + Power.

    Alternatively, on some devices and recoveries you can use fastboot to boot directly into the freshly flashed or any other desired recovery:

    fastboot boot <recovery_filename>.img
    

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 arm architecture).
  2. If you are not in recovery, reboot into recovery:
    • With the device powered off, hold Volume Up + Volume Down + Power.
  3. Now tap Wipe.
  4. Now tap Format Data and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage.

  5. Return to the previous menu and tap Advanced Wipe, then select the Cache and System partitions 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 filename.zip those packages in sequence.

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