I have a new iPhone 6 and have tired to restore it from the back up of my previous phone. when I do this it either says 'unknown error (-54)' and will not restore from back up or it begins to restore and the says the iPhone has been disconnected during the sync - which it hasn't.
This continues to happen and is refusing to sync!! I have tired to change to properties of iTunes to not read only anymore and also tried to sync as an administer - as the forums suggested but nothing seems to work.
also tried other USB ports
Does anyone have any other suggestions?
iPhone 6, iOS 9.2.1, null
