Install LineageOS on wt88047

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
    

Updating firmware

  1. To find your model number, “Open “Settings”, navigate to “Phone Info”, and take note of the model number below the “model” header:
    • Devices with model numbers 2014811, 2014812, 2014817 2014818, 2014819, and 2014821 should download the firmware labeled wt88047.
    • Devices with model numbers 2014813, and 2014112 should download the firmware labeled wt86047.
  2. Download the relevant firmware zip file from here.
  3. Sideload the firmware .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.

Installing LineageOS from recovery

  1. Build a LineageOS installation package.

    • 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, repeat the sideload steps above for 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’.
