The way it works is that you need a proprietary app (in the past it was on PC and you had to connect the phone over USB, now it’s an app on the phone) where you log in with the Xiaomi Account that is also logged in on your phone. Then you “request” a bootloader unlock and after a week or so you can do the same thing again and it unlocks the bootloader. My guess would be that it uses encryption on the phone in some way and the server sends the decryption key. I also just thought that the process is so tedious that someone should have come up with a way to circumvent it already but maybe no one wanted to invest the time since it was possible that way. Either way, I don’t have experience with this kind of thing, so I’m not really the person to figure it out.
Does it require a code to unlock? You could brute force the code
