The iPhone was already updated to the latest iOS before leaving the store. IPhone 7+ with 256 gigs. Has anyone seen a situation when updating the iPhone 7+ from a restore and it almost completes it's update with everything working. Then you go into purchased apps and start downloading the ones that failed to update only to have the phone screen go black with a rotating wait symbol then with a black screen like that for about 4-5 seconds then flashes the passcode pad up for a half second with a short tone. This sequence never stops. I took it into iTunes without any success on recovery. It still takes me to this described rotation. Anyone????
