Thank you, mate, for your response, but take a look again at my problem. The MI Account is removed, but after connecting to WIFI, the phone ask me again for MI Account. It's temporery! And when I try to prevent relocking through "MI Prevent Relock", the set hangs on logo and I have to flash it to revive it. I tried downgrading to EMUI 8 - again the same problem. Hangs on "MI" logo. So Im asking, what should I do to remove MI Account for good!
