So remember the #miunlock scare about our way older miui devices no longer being unlockable? (mido/redmi note 4)
Not sure how real it is... I managed to unlock it: https://infosec.exchange/@sounddrill/116080525851768716
This phone has had the same #miui account for years though, not sure if that is a factor
I hope this helps somebody!
More info: I used this tool which queries official mi unlock servers
and not the #EDL exploit

the last time this account did an unlock was in 2023(took 2 weeks that time) so this unlock took no delay
