store sold phones should arrive relocked - but will not be signed with oem key obviously (yellow state). I wonder if the screen reacts to that but with the wrong ref.code. To know I’d need to see fastboot params or just a screenshot (hide serials, example photo).

(curious: if you continue on the option to proceed, are any functions disabled?)
