Wifi will not connect and iCloud verification failed
Hi - i'm trying to reset my wife's iPhone ever since her phones been having random freezes and reboots over the last few weeks. She's on an iPhone 5 (Ver 8.3 {12F70}).
There's 2 main issues going on here:
1 - Wifi just won't connect. The Wifi button remains Grey and the spinner keeps going around in a loop but won't detect any hotspots. I force reset the phone and reset network settings - that helps connect to the wifi for about 5 minutes and then it's lost again. This was a real cause of concern as it resulted in the phone hanging and misbehaving a lot. So the next option was to reset, here's the second problem.
2 - iTunes is unable to restore the phone and returns a generic error message. I am also unable to erase content etc from the phone as i keep getting an annoying "iCloud Verification Error".
Im at the end of all options to explore, so any assistance would be appreciated.
Thank you.
iPhone 5, iOS 8.3
