Iphone 6 - boot loop and then when i try to repair i get error 9 and 4013
Phone is not jailbroken and i took it to apple store and they somehow managed to fix it. But now i turned my phone off and when i tried to turn it back on it boot looped.
Try the steps here. If they do not help I would take it back to the Apple Store.
If you see error 9, 4005, 4013, or 4014 when you restore your iOS device - Apple Support
