Thanks for your reply. My Apple ID was invalid immediately when I tried to sync pictures from my old iPhone 4, which transferred an old , now invalid, email I had 10 years ago. I have spent over 15 hours on phone to different Apple support and it always comes down to a hard reset.. When I did this as instructed, iPhone became fully locked to owner unless I could sign in.. Next step is to prove ownership to get Apple to reset for me.
I have provided online Costco receipt with price and description of iPhone and model, my name and membership. Since receipt does not have serial number on it, I also provided picture of iPhone showing it’s serial numbers, and a picture of box with all serial numbers and bar codes. The answer is always the same, proof is insufficient since serial number not on online receipt. So I am left with a barely used iPhone brick.
