Serial number on main board
hello i was wondering if you could help me, i sold a iPhone 6 about a week ago on ebay and now the buyer wants to return the phone saying it no longer powers on, I've checked the feedback and it shows he's brought a few main boards for the iPhone 6 before hand
how do i check the main board is the correct one for the phone if apple haven't included a serial number on the main board and the phone is completely dead?
thanks
