Hi everyone.
Actually, my Rom installed is 9.6 by Xiaomi.eu 8.5.3 Beta (weekly).
I would want to know if via TWRP , I can do this without data and root loss.
1) Boot in TWRP mode
2) Wipe Dalvik / ART Cache
3) Install 8.6.14
4) Wipe Dalvik / ART Cache
5) Reboot
6) Boot in TWRP mode
7) Wipe Dalvik...
