Hi guys, I have one odd question.
Is it possible to downgrade android and OneUI version to android 11 oneui 3.1?
I'm on the latest version od Android with August security patch.

i thought with the '5' baseband, we couldnt go back, plus it wont boot into bootloader any longer even thou the option is still there in the recovery menu, just a full reboot.... id love to read up on where these steps are... from what i read, im hosed after being upgraded from 4 to 5? plz tell me im wrong, and there is light at the end of the tunnel... ID kill to go from U to U1
