Basic requirements

warning

IMPORTANT: Please read through the instructions at least once completely before actually following them to avoid any problems because you missed something!

  1. Make sure your computer has working 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:
  4. adb reboot bootloader

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

  • With the device powered off, hold Volume Down + Power.
  1. Once the device is in fastboot mode, verify your PC finds it by typing:
  2. fastboot devices

check

TIP: If you see no permissions fastboot while on Linux or macOS, try running fastboot as root.

  1. Flash recovery onto your device:
  2. fastboot flash recovery twrp-x.x.x-x-wt88047.img

check

TIP: The file may not be named identically to what stands in this command, so adjust accordingly.

  1. Now reboot into recovery to verify the installation:
  2. With the device powered off, hold Volume Up + Volume Down + Power.

Alternatively, you can use fastboot to boot directly into the freshly flashed or any other desired recovery:

fastboot boot twrp-x.x.x-x-wt88047.img

Installing LineageOS from recovery

  1. Download the LineageOS install package that you’d like to install or build the package yourself.
  2. Optionally, download additional application packages such as Google Apps (use the arm architecture).
  3. If you aren’t already in recovery, reboot into recovery:
  4. With the device powered off, hold Volume Up + Volume Down + Power.
  5. Go back to return to main menu, then tap Wipe.
  6. 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.
  7. Return to the previous menu and tap Advanced Wipe.
  8. Select the Cache and System partitions to be wiped and then Swipe to Wipe.
  9. Sideload the LineageOS .zip package:
  10. On the device, select “Advanced”, “ADB Sideload”, then swipe to begin sideload.
  11. On the host machine, sideload the package using: adb sideload filename.zip
  12. (Optionally): If you want to install any additional add-ons, adb sideload /path/to/zip those packages in sequence.

info_outline

NOTE: If you want Google Apps on your device, you must follow this step before the first boot into Android!

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