Long story short....I sold my iPhone 6s+ yesterday. I erased all content and sold. She gets it home and cannot activate it. Likely story is the darn "Find my iPhone". I log into my iCloud and turn it off. I also remove the device from my Apple account like I read online. She still cannot set up the phone. It's asking for the original Apple ID and PW. Basically I have to go get the phone from her and log into it again??? This is insane.....like I have to set up the phone again under my name and do something??? Apple is of ZERO assistance.....can anyone help me with what might be wrong? P.S. The phone is an unlocked phone from Apple. It was under the Upgrade Plan and paid off (even tho that is not the problem here).
