I was going to sell my Ipad Pro 12.9 to a neighbor today but had to restore it to 15.6. I forgot a BIG step. I forgot to remove my Beta Profile. It went through the whole process and now is stuck on the White Apple Screen. I do have Apple Care but the next available appt for my area is Tuesday. Just wondering if anyone had done this before... I have tried to do a soft reset, and plugging it into my computer but nothing happens. Any tips?
