I bought an iPad on eBay recently. It seems to be functioning in the little that I've used it. I actually got it a couple weeks ago and did some initializing at the beginning. Not sure how far I got. But today when I tried to use it I can't get past the "Choose Backup" screen. It just keeps processing but not doing anything. I'm signed into iCloud fine I think, and my wifi is also fine. Is there anything I can do? I can even reset if that's necessary since I haven't actually done anything in the iPad yet. But not even sure how to do that.
