How can we reset a used iPad Mini without the original Apple ID?
Three weeks ago my grandpa bought an iPad Mini from an ad on Craigslist, and the original owner did not deactivate "find my iPad" or reset it to factory settings and remove her Apple ID first. He has tried contacting her for assistance but has not received any response in all this time. We've followed directions for how to do a manual reset of the iPad, but it always states that it's locked to the original Apple ID and requires a password.
Is there anyway he can unlock the iPad from that original Apple ID and use his own? The iPad does operate fine, but without his own Apple ID he cannot download apps or sync it with his other devices.
