I am facing difficulty in unlocking the bootloader of my device. The Mi Unlock tool says "couldn't Unlock, unknown error (-1)" during the final unlock process.

Do I have to wait a particular time before it can be unlocked. Please I need help

Using Global version 10 updated to 11

I also have to wait a week after request unlocking. Make sure you send request and the mi unlock tool is the lastest version from official website.

I cannot even start the procedure it keeps saying my sim card is not activated, and when I try to see the unlock status (part of the unlock procedure), it keeps sending me an error that it cannot send the sms, but i can send sms no pro blem and have more than enough data available, I cant go past this until my sim gets "activated"no idea what it means, I have been using this sim/number for years
