I have done 4 complete restores on my iphone4 but it still fails to complete or turn on.
Itunes and my OS are updated. I have pressed both buttons on the phone to get itunes to wipe the phone, the system starts but each time it fails. I have turned off the firewall on the computer. (iMac).
It is sounding like the battery has failed, is it worth replacing or could it be a few things that have failed?
thanks
iPhone 4, iOS 7.1.2
