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
   

   check

   Tip: If you see no permissions fastboot while on Linux or macOS, try running fastboot as root.
5. Flash recovery onto your device:

   fastboot flash recovery <recovery_filename>.img
   

   check

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

   Tip: Some devices have buggy USB support while in bootloader mode, if you see fastboot hanging with no output when using commands such as fastboot getvar .. , fastboot boot ..., fastboot flash ... you may want to try a different USB port (preferably a USB Type-A 2.0 one) or a USB hub.
6. Now reboot into recovery to verify the installation:
   • With the device powered off, hold Volume Up + Volume Down + Power.

Updating firmware

• If you are installing from LP (5.x) stock MIUI, nothing needs to be done.
• If you are installing from KK (4.4) stock MIUI, you will have to update the device’s 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. Download the LineageOS installation package that you would like to install or build the package yourself.
   • Optionally, download an application package add-on 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.
     check

     Tip: If the process succeeds the output will stop at 47% and report adb: failed to read command: Success.

7. (Optionally): If you want to install any add-ons, repeat the sideload steps above for those packages in sequence.

   Note: If you want the Google Apps add-on on your device, you must follow this step before booting into LineageOS for the first time!
8. Once you have installed everything successfully, run ‘adb reboot’.
