No problems updating iphone 5 and the mini ipad however my other ipad has caused the pop up error message of -1 and I am unable to do anything!!!! I was offered restore but am also unable to do this. cannot move beyond the connect to itunes visual Sounds serious huh ???!!!
Problem sorted. Thanks
How did you solve it?
I have the same problem and I cannot restore it.
exactly same problem here..
I eneded up turning it off and leaving it for half an hour, turned it back on, the connect to itunes motif came up, as it had been when I shut it down, On connection it went successfully to restore mode and all was good and straightforward from there !!
Good luck...hope it works for you
