Short information about different ROM versions:

• Global MIUI Rom starts from 8, 8.3 or 8.3.1
• Developer ROM version start from the year it has been released.

In case your Mi account is old enough, you may try to unlock even on a Stable ROM version, but this happens very rarely. In case you aren’t able to get unlock permission, then you are required to flash Weekly Developer ROM.

There are exceptions for a couple of devices: Mi4c and Mi Note Pro device comes with unlocked bootloader. You’ll need to flash China Developer ROM version, got bootloader locked again, and then request permission to unlock bootloader. Waiting time in this case is around 4-8 days, and all that time Mi Unlock will be showing “Current account is different from the account info on the device” message.
