I bought the ifixit screw driver set I’m using the 0.8 star pentalope bit and the screws won’t come out

Are you talking about the two screws at the bottom of the phone? If so then you need to use the P2 or P5 bit.

this is purely dependent on whether you have the correct size screw driver or if the threading has gone in the screws. if its a case that the threading has gone you’ll need to create tension in the screen before using a magnet or a pentelope screwdriver to pull the screws out of place.
