I have an iPhone 6 and have backed that phone up via iTunes. I just bought a used iphone 6 plus and I tried to restore that phone from the iPhone 6 back up but I get a "restore process failed message" when I turned on the iPhone 6 plus I started it as a new iPhone, set the plus as a new phone and then tried to restore from an my backed up iPhone 6. Is this what is causing my problem with restore from the iPhone 6?
