I backed up my 7+ before I did anything with my X. When I restore my X, everything works except my Messages app. It force closes every time I try to open it. I've been on the phone with AppleCare 3 times for a total of 7.5 hours. I've tried 3 different backups through iTunes & 2 via iCloud. All them with the same result. Anyone have any suggestions or fixes? I really don't want to setup as new and input 445 contacts and all of my apps plus lose all of the text threads.
