Install LineageOS on wt88047

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
   

   If you don’t get any output or an error:

   • on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
   • on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable and port!
   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.
5. Flash recovery onto your device (replace <recovery_filename> with the actual filename!):

   fastboot flash recovery <recovery_filename>.img
   

6. Now reboot into recovery to verify the installation. Do not reboot into the existing OS, since it will overwrite the recovery you just installed!

   • With the device powered off, hold Volume Up + Volume Down + Power.

     Note: If you can’t power down the device, try long-pressing the key-combination (if any was used in the instructions above) until the device reboots and follow the instructions above

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. Build a LineageOS installation package.
   • (Optionally): If you want to install an application package add-on such as Google Apps (use the arm architecture), please read and follow the instructions on Google Apps page
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: Normally, adb will report Total xfer: 1.00x, but in some cases, even if the process succeeds the output will stop at 47% and report adb: failed to read command: Success. In some cases it will report adb: failed to read command: No error or adb: failed to read command: Undefined error: 0 which is also fine.

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’.
