It is interesting how experienced user can fix such a kind of bug as not working MIUI. Even I can read this messages on my phone bit there is blank desktop. For windows I know how to fix but first time in my life I can see the same bug.
I think it is good to put with this beta recommendation for cleaning cache and turning on USB debugging before update just with the link to download with red marks!!!
With this beta I have tried to install latest twrp and orangefox for OS1 but it goes to constant fastboot. After installing this beta as update it goes to blank screen and I can play music from tools buttons for wi-fi BT etc.
