I working whole night with Recovery, Fastboot, Flash.
I was on Xiaomi.eu 12.0.1 global Android 11, Redmi note 9 Pro (Joyeuse).
After this update MIUI and Android, using this phone is tragic (Clean Flash).
Gestures lags, battery, stability, remote desktop - worse than 06.2020 and Miui 11.01 EEU.
Cant install this rom - failed mount /system-root & /vendor
For a while i lost hope to get out from stock rom back to .eu rom, because twrp gonna die.
For now i install Pixel Plus.
.Flash via fastboot stock rom
.flash OrangeFox Recovery (only this recovery can encrypt new bootloader) via ADB & put to memory .zip, and flash via recovery, after install via adb
.format data type [yes] - reboot to RECOVERY if miui gonna boot - ****ed up
.format cashe dalvik etc. - reboot to recovery
.now everything is encyrpt - you can install custom rom.
But this rom no work - sad, because it was my first choice
Sorry for my english
