Downgrade to version 9.8.1 beta(Android 10 to 9)

[Iscarlat]

Hey guys, does someone know How I can go back to version 9.8.1 beta, Now I'm using 9.8.22 with Android 10 and every time I try to install the version 9.8.1 It stays in infinite bootloop, even wiping I can't use 9.8.1 anymore

Hi, to reuse the 9.8.1 version, you must reflash the latest official xiaomi rom with mi flash : http://c.mi.com/oc/miuidownload/detail?guide=2 without relocking the bootloader

Then reinstall twrp : https://forum.xda-developers.com/Mi-9/development/recovery-unofficial-twrp-xiaomi-mi-9-t3905825

In twrp format data, then reboot into recovery mode

You can now flash the 9.8.1 version then reboot your phone into system mode and enjoy

infinite bootloop was at "unlocked" screen, or the "mi" logo moving?

0. Make a backup to PC of all needed data from phone.
1. Flash TWRP from 9.8.1 thread, it should be something like 3.3.1.34 version
2. Format data in TWRP in Wipe menu (you will lose ALL data on your phone). You need exactly to Format data (gray button at the bottom), not just wipe.
3. Copy 9.8.1 zip to the phone and install it
