If you want to uninstall this custom ROM and back to stock ROM, just flash the stock ROM to your device. Flashing stock ROM will also uninstall TWRP Recovery and it will back to stock Android Recovery.

Notes / Warning!

  1. Use at your own risk, I’m not responsible for bricking your device.
  2. Using the incorrect file may brick your device.
  3. If your target device has a custom firmware flash counter, Rooting will trigger it. If you’re lucky, Triangle Away has support for your device and can be used to reset the counter.
  4. If you have a KNOX-enabled device, flash custom rom and Rooting will trip the KNOX WARRANTY VOID status!
  5. If your device storage is encrypted, Rooting will wipe your data !
  6. If you have locked bootloaders, flashing one of these will probably brick your device – with the exception of Nexus devices, which will usually automatically “OEM unlock” and wipe your data !
  7. Make sure to backup your important data before root it.

    I have this installed on a A51 and the audio is always stuck at 100%. When I try to change my volume, it just says that it’s at 0. Any help would be appreciated.

    Is it possible to install Android 12 on Note 20 Ultra?
    I tried the instructions from this post, but it does not work.
    Android Logo stays infinitely, it does not boot.
