How I Can Downgrade From U3 To U1 “Oreo To Nougat”
I want to downgrade my phone from Oreo to Nougat My phone is Samsung J730F.
But the dilema is that Samsung locked the boot-louder.
Can I go back by flashing the phone combination ROM then flash my phone with stock ROM to bypass this lock?
Note: FRP, google account protection is OFF and USB debugging is ON.
And I have rooted the phone and flash it with combination ROM. My question is what should I do after flashing it combination ROM? Should I flash stock ROM 4 files or replace only some files?
