Ok i am stuck @ "couldnt verify device" error. I asked for unlocking permission. I am running eu rom with nougat on my mi 4c (first one, the one with huge battery drain, almost unusable) . After sms approval, downloading mi unlock app, rebooting phone in fastboot ( after oem unlock enabled such as developer usb in developer mode) i cannot go further than 50% as you see in the screenshot. I tried loggin in with both telephone number and mail, tried locating phone with micloud, nothing.
