When i hook up my iphone via USB, itunes automatically does a sync and backup but recently i've gotten the notification that itunes cannot backup my iphone because a session cannot be started. Also, my ios 7 beta 1 just expired so currently, i cannot get in to my phone- long story short, is there any way to fix this back up problem without having to change anything on my phone? Also I've read that it helps if you uncheck 'sync over wi-fi' on itunes; i did this and it didnt help.
Added (1). I want to backup so that i can downgrade back to ios 6.4.1.do i still need to get a registered UDID?
