Try a 000 Phillips screwdriver on the Two 3.2 mm and the One 2.5 mm screw. They were too shallow for my 00 Phillips, which ended up rounding the slots in all three. I had to notch them all with a Dremel cutting wheel so I could unscrew them with a small slotted screwdriver.

I was unable to unscrew the 3.9 mm Phillips screw with a 00 screwdriver. It ended up rounding out the head, and I had to use a micro screw extractor to get it out. I had to notch the screw with a Dremel cutting wheel so I could screw it back in with a small slotted screwdriver during reassembly. If I could go back in time, I’d try a 000 Phillips instead.

We had to move to the new assembly:

tiny rubber part to the left of the speaker contacts (pinned by the plastic speaker housing)

speaker (aka earpiece - step 10)

plastic speaker housing (aka earpiece casing - step 11)

tiny front facing camera

left rear camera (the middle rear camera stayed on the logic board).

other than that, the guide, combined with careful observation, was help us successfully replace the broken screen.
