"Additional verification" loop on iPhone 4 (iOS 7.1.2, I think)
I am having the same problem described in this posting:
Additional verification required but no f… - Apple Community
Basically, my iPhone is stuck in an infinite loop where it keeps requesting "additional verification", sending me several verification codes at a time, instructing me to enter them but giving me no place whatsoever to do so (and no keyboard to do it with), returning to the home screen, asking me to agree to terms and conditions, then repeating the whole sequence again.
I do not know how to get out of this loop. It keeps turning on my phone every few minutes to tell me it needs this verification again, and it is draining my battery rapidly to do so.
I have shut down and restarted the phone repeatedly. I do not dare reset the phone because I do not know the last time, if ever, it was successfully backed up, and do not know how to verify this.
I have a feeling the whole process is not compatible with iOS 7.x, but I can't make it stop.
Do I need to define an iCloud account at all? What do I lose by deleting it entirely?
I'm at my wits' end so if someone knows a solution, I'm all ears (so to speak).
