[rebeyeah]

after upgrade to 9.10.17 -android 10 and miui11- i have some bluetooth issues, and my recovery can't read internal storage, now i have to flash with otg memory.
can downgrade to 9.9.26, based on android 9 and miui10, or is possible to brick the phone?
i have a mi9se 128 global.

Here TWRP witch can read your storage: http://files.mi-room.ru/files/twrp/grus/3.3.1-1018-DX/recovery.img

Bluetooth issues as i understand can be solved by clean flash. Or not Just read the 9.10.17 thread.
