I'm having an awful experience trying to update. Without going into too much detail, my main question is if there is anyway to make sure my iPad can be successfully updated (i.e. I don't get the "Device isn't eligible for requested build." error) without waiting for it to back my iPad up? For some reason, it takes 45 minutes to back up less than 15 GBs of used space (really? Time Machine when connected to my computer directly takes that long to back up 100+ GBs if I recall correctly) so I have to wait for that long, THEN see if it worked correctly. Also, I keep reading that some people who have a jailbroken iPhone are receiving this error. While I do have a jailbroken iPhone, my iPad is not jailbroken, so I'm not sure why IT would be receiving this error? And for future reasons, what should I do to make sure my iPhone updates successfully?
