Xiaomi.eu to global beta/stable switching issues

[kogan92]

Since I can't change region on xiaomi.eu weeklies and on 1st July there's no more betas for everyone. I decided to switch to the official ROMs. I tried any tools to do the switch, but when I connect the phone in fastboot mode to the PC with any tools (xiaomitool or miflash), It quits from fastboot mode and a "press any to shutdown" displays on the screen of my phone or I am able to start the flashing but then I get the message "error flashing" or "missmatched image or device".
What did I do wrong? Is it because of the rollback "ban"?
I'm on 9.6.13 beta
