The screws holding the lightning port in are not unscrewing
I am replacing my lightning charger port in my IPhone 7 and the screws on the inside holding it in on the port to the wall are not moving. I have use both the phillips head(ph000) and the standoff bit that were included in the Ifixit kit for replacing the lightning port, but both won’t grip. Is there anything I should know that would help or I am doing wrong? Thank you
