Error 21 at trying to recovery
Hi. I have iphone and i have problem. When i plug him into charger, he just show Apple Logo and then restart after 3-5 secs. I try to plug him into recovery mode (button + plug cable) he shows itunes and itunes on computer recognize him. I'm just clicked restore iphone and it say's error 21. Phone have Front Glass Cracked, but screen was working good, and mobile was working good too. Can be this problem battery ? Because when i plug into computer itunes recognizing device.
Is this a good question?
