Bro I want to install a custom ROM on my device do I need to unlock my bootloader? I didn't see any tut to do that how do I proceed. Precisely I want to install the pixen os.
This is for the 9 Pro but it's the same process (you will want to check both the 9 and 9 Pro forums because the 9 Pro is more active and devs will often just drop their thread there for both devices).
Without magisk, if you unlock bootloader from oos 12 , L1 will keeped and it will not change to L3 even you downgrade to oos 11
