Out of nowhere this morning, 5s heats up, starts getting sluggish and unresponsive. I power it down for a restart. What would normally be a 30 second restart has turned into a 3 hour ordeal. The 5s has been on the Apple logo ever since, and since I don't have physical access to my MBP I am trying to update it to 9.3.1 via a computer lab Mac (which gave error code 2006...) I do NOT want to restore the phone. I have over 7 GB worth of pictures that I do not want to lose. What options do I have? And it's not even jailbroken!!!
