  1. Have tried both the method but does not work for me. In the first method, it stops at 50%, saying can’t verify the device, or sometimes Error 501 or the phone is not connected
    In the second method, saying that the device is not connected to mi account. Please help I really need to unlock bootloader for my Redmi 3s

  2. Followed the procedure using both (ie logging in using email/phone number). it keeps giving the same error message. Any help would be greatly appreciated. Thanks.

  3. I got the unlock permission from miui site. But when I try to add my account and device in the mi unlock status, it says “couldn’t verify, wait a min or two and try again”. I’ve waited and tried it almost 10 times, but it still shows the same message. Please help.
