- battery drain, even when the phone is idle
- a permanent notification that the device is being charged through USB, even when not connected
- when the device is connected, it won't charge, unless a reboot
Now I wanted to try to rollback to an older release or try Ubuntu Touch, but I have not been successful.
- ubports installer does find my Volla Phone, but hangs when installing (is does not do any installing)
- fastboot does not recognize any device
- adb can access the device in normal mode, but not in recovery mode (device unauthorized)
Some help would be great:
- Does anyone have experienced troubles after the Android 12 update?
- Perhaps a way to fix the for-mentioned problems?
- Any ideas how to solve the unauthorized device for adb in recovery mode?
