I did literally everything according to instructions, still cant get past this "Unknown Error(-1)". This error happenes at 99% all the time
verification done, but unlock fails at 99.
old mi unlock tools not working also, shows same error.

Just this problem here, nothing else:

Noob question: For Bootloader to be unlocked through official mi unlock tool, do u need 2 different internet connection?

Because, i have only one sim and use it to get internet, and have laptop connected to it, so when i put my redmi Y2 to fastboot, theres no internet connection to laptop during unlocking process.
I took the sim out of my fastbooted y2, same unknown error(-1) occured at 99%,
Then i put that sim into my older phone (not y2), and had laptop connected to it, it stopped at 99% again, but showed different error "Your MI ID not associated with a phone number".

:confused:
So both errors happening at 99%, badly need some guidance from those who have unlocked bootloaders for their S2 or Y2 models using official MI Unlock Tool. Thank you
