Install LineageOS on flox

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
   

   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!

4. Now type the following command to unlock the bootloader:

   fastboot oem unlock
   

   info_outline

   Note: At this point the device may display on-screen prompts which will require interaction to continue the process of unlocking the bootloader. Please take whatever actions the device asks you to to proceed.
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 Lineage Recovery. Simply download the latest recovery file, named something like lineage-18.1-20230128-recovery-flox.img.
   warning

   Important: Other recoveries may not work for installation or updates. We strongly recommend to use the one linked above!
2. Connect your device to your PC via USB if it isn’t already.
3. If your device isn’t already in fastboot mode, 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
   

   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. Temporarily boot recovery on your device (replace <recovery_filename> with the actual filename!):

   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.
   info_outline

   Note: The repartition script package in question isn’t signed with LineageOS’s official key, and therefore when it is sideloaded, Lineage Recovery will present a screen that says Signature verification failed, this is expected, please click Continue.
4. Now run adb shell from your Terminal/PowerShell, and run the following commands within it:
   • modify
   warning

   Warning: This step may take up to 5 minutes, please ensure your USB connection/power source isn’t interrupted during this time.
5. The device will reboot whatever your previous recovery was, please select an option labelled like “Reboot to bootloader” or “Reboot”, then “Bootloader”.
6. Format your data partition:

   fastboot -w
   

7. 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.
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): 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 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.
     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.

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

   info_outline

   Note: Add-ons aren’t signed with LineageOS’s official key, and therefore when they are sideloaded, Lineage Recovery will present a screen that says Signature verification failed, this is expected, please click Continue.
   info_outline

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