iPad IOS matching
I have a gaggle of iPads, iPods and Macs of various ages, and I serve as my 88 year old father's IT department (as well as my 5 year old son's), so it helps greatly if our set ups are identical. I bought a few iPad 3s last year with iOS 5.1.1. I want to keep them on iOS 5.1.1 for a variety of reasons, but overall its for continuity- everything runs right, and I can mimic my father's steps to sort out issues over the phone or Skype, my son's iPad1 uses the same apps... My father and I live 3000 miles apart, I can't get to his hardware physically, I have to mimic his steps and instruct him. He gave up on the iPad 3 (wifi) I gave him, and gave it back to me. Someone had been fooling around with the settings, and among other things, upgraded to iOS 6.1.3. Maybe if I can get it back to 5.1.1 I could get him to use it again, or at least it would be more usable for me or my son.
I have read a lot of the discussions here about the inability to downgrade the iOS, so I expect no help there (although it would be great if I could).
I have reset the settings, but the iOS remains untouched. I haven't tried erasing, I think that would just get rid of my apps and data, but the iOS would still be 6.1.3 (and I would have to sort out the legacy apps).
Is there a way to clone my iPad3 to my Dad's iPad3, transferring my iOS 5.1.1 especially, and even better all the apps and settings?
If I backed up my iPad3, could I restore my iPad3 backup to my Dad's iPad3 including the iOS?
Is there any way I could restore it to the way it came out of the box, with iOS 5.1.1 ?
If I can't do any of that, is there a way I could buy an iPad 3 with 5.1.1- I would sell this one.
Thanks in advance for any help
