Method 2: Install via LineageOS Recovery

Step 1: Installing LineageOS Recovery Temporarily:

    1. First of all, you need to unlock the bootloader on your device
    2. Download and install the ADB and fastboot binaries on your computer.
    3. You can now install the LineageOS recovery on your phone.
    4. To install the recovery, you need to boot your device into the bootloader.
    5. Run the command window by pressing the Shift key + Right mouse click adb command window
    6. Enter the command given below to boot your device into bootloader:
      adb reboot bootloader
      • You can boot into fastboot mode via a key combination:
      • With the device powered off, hold Volume Down + Power. Keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.
    7. Once the device is in fastboot mode, verify your PC finds it by typing:
      fastboot devices
    8. Now temporarily flash the recovery image by typing the command given below:
      fastboot flash boot <recovery_filename>.img


      NOTE:
       Outdated fastboot releases dropped legacy A/B support, so it might attempt to flash to boot__a / boot__b rather than boot_a / boot_b if you try to flash boot. In this case, you must update fastboot to a release newer than or equal to 31.0.2. Alternatively, you can manually specify which slot to flash to based on what slot fastboot failed to flash to. For example, if fastboot fails to flash to boot__a, you must flash to boot_a.
    9. With the device powered off, hold Volume Up + Power. Keep holding both buttons until the logo appears on the screen, then release.

Step 1: Installing LineageOS from recovery:

  1. Download the latest LineageOS build and additional gapps addon and move it to the Unihertz Jelly 2 internal storage.
  2. Reboot your device into recovery by the combination key:
    • With the device powered off, hold Volume Up + Power. Keep holding both buttons until the logo appears on the screen, then release.
  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 screen on your recovery and 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
  5. (Optionally): If you want to install any add-ons, click Advanced, then Reboot to Recovery, then when your device reboots, click Apply Update, then Apply from ADB, then adb sideload filename.zip those packages in sequence.
  6. Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.
  7. That’s it! If you want to root, you can root using magisk.
