I used the same driver for all of these screws. Had to apply a lot of pressure before trying to unscrew it and it was fine.

This was SO hard for me to do with the spudger. I couldn’t get a gap to insert it because my phone was so cracked (even though I used tape on the front) to get a solid seal with the suction cup. I ended up taking a VERY thin knife and inserting it straight down to make the initial break that allowed me to insert the spudger.
