hi, i am having aproblem right now trying to flash miui 12. first time i just formatted the phone in twrp. used adb push to push the zip on the phone. and flashed it. it was successful but after booting into the system it had a password for some reason and there was no setup screen. so i tried to reflash by formatting again and repeating the process. now i boot into system and it just goes into bootloop at the MI boot screen.
