Basic requirements

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

Unlocking the bootloader

  1. Connect the device to your PC via USB.
  2. 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 until the bootloader appears, then release the buttons.
  3. Once the device is in fastboot mode, verify your PC finds it by typing:
    fastboot devices
    
  4. Now type the following command to unlock the bootloader:

    fastboot oem unlock
    
  5. If the device doesn’t automatically reboot, reboot it. It should now be unlocked.
  6. Since the device resets completely, you will need to re-enable USB debugging to continue.

Installing a custom recovery using fastboot

  1. Download a custom recovery - you can download Lineage Recovery. Simply download the latest recovery file, named something like lineage-18.1-20211202-recovery-flox.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 until the bootloader appears, then release the buttons.
  4. Once the device is in fastboot mode, verify your PC finds it by typing:
    fastboot devices
    
  5. Temorarily boot recovery on your device:
    fastboot boot <recovery_filename>.img
    

EFS/Persist Backup

  1. If you are not in recovery, reboot into recovery:
    • With the device powered off, hold Volume Down + Power until the bootloader appears, then release the buttons. Use the volume buttons to scroll to “RECOVERY” and press Power to select.
  2. Now, use the volume buttons to select “Advanced”, and then “Enable ADB”.
  3. Now open Terminal (Linux/macOS), or PowerShell (Windows), run adb shell, and then run the following commands within it:
    • dd if=/dev/block/mmcblk0p2 of=/sdcard/modemst1.img
    • dd if=/dev/block/mmcblk0p3 of=/sdcard/modemst2.img
    • dd if=/dev/block/mmcblk0p4 of=/sdcard/persist.img
    • exit
  4. Now from that same Terminal/PowerShell, run:
    • adb pull /sdcard/modemst1.img
    • adb pull /sdcard/modemst2.img
    • adb pull /sdcard/persist.img

Repartition

  1. Download the flashable repartition script from here.
  2. On your device’s screen, choose “Apply Update”, then “From ADB”.
  3. From your Terminal/PowerShell, run adb sideload /path/to/flo-deb_clamor_repartition.zip, filling /path/to/ in with the path you downloaded the repartition zip to.
  4. Now run adb shell from your Terminal/PowerShell, and run the following commands within it:
    • modify
  5. The device will reboot whatever your previous recovery was, please select “Reboot to bootloader” if it’s the stock recovery or “Reboot”, then “Bootloader” if it was TWRP.
  6. Format your data partition:
    fastboot -w
    
  7. Flash recovery onto your device:
    fastboot flash recovery <recovery_filename>.img
    
  8. Now reboot into recovery to verify the installation:
    • With the device powered off, hold Volume Down + Power until the bootloader appears, then release the buttons. Use the volume buttons to scroll to “RECOVERY” and press Power to select.
  9. Click,”Factory Reset”, then “Format system partition”, then when prompted, select “Yes”.

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 Down + Power until the bootloader appears, then release the buttons. Use the volume buttons to scroll to “RECOVERY” and press Power to select.
  3. Now tap Factory Reset, then Format data / factory reset and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage, as well as format your cache partition (if you have one).
  4. Return to the main menu.
  5. Sideload the LineageOS .zip package:
    • On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
    • On the host machine, sideload the package using: adb sideload filename.zip.
  6. (Optionally): If you want to install any add-ons, repeat the sideload steps above for those packages in sequence.

  7. Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.
