Got to step 13 and could not remove the 1.3mm screw (yellow circle), even using a different Phillips head screwdriver than the one that came with the kit. So frustrating. Was able to remove the other screws leading up to this point without difficulty (used the saran wrap trick on the other screws to prevent stripping, but this 1.3mm screw just would not budge).

Ended up abandoning the screen replacement--luckily the phone works after putting it back together.
