I am trying to restore iOS 6.1.4 on my iPhone 5 (US model A1428) due to some strange recent software glitches (the iPhone keeps reverting back to the home screen for no reason). Whenever I try to recover my iPhone, iTunes gives me an alert that says: "The iPhone could not be restored. This device is not eligible for the requested build." I am using the most recent update of iTunes 11.0.4. I have tried to recover the phone in both regular and DFU mode with absolutely no luck. Does anyone have a way to resolve this issue? Thank you!
