I have special device, that have no screen at all. Only 3 buttons: volumes and power. So the problem that I've used hard reset option and after that on all my computers I got error:
error: device unauthorized. Please check the confirmation dialog on your device.
The problem, that I can't check that dialog - no screen or input methods. I've tried to connect from recovery mode, but from it the same.
What can I do in that situation?
