If you has TWRP 1227, you must flash the original ROM with MiFlash, and them flash TWRP 1102 or 1217 ( fastboot) nada install 10.2.1.0 ROM againHello! I had troubles with this new ROM. So, now I can't back to the older ROM because my TWRP is DEAD!
My finger print stoped to work! The automatic rotation stoped to, and my aproximity sensor doesn't work!
