Hi guys, my brother just woke up and his iPhone was in DFU (with the iTunes screen) and a support/restore link on top. The weird thing is, he installed iOS 10 a week ago flawlessly, he just woke up today and was greeted by that screen. Is there a way to fix this without restoring the phone? He plugged the phone, a progress bar filled on the phone but now iTunes is stuck on "Waiting for iPhone". Most odd bug I've ever seen. Thanks!
