Remove the following screws securing the front panel assembly cable bracket to the logic board:

One 1.7 mm Phillips #000 screw

One 1.2 mm Phillips #000 screw

One 1.3 mm Phillips #000 screw

One more 1.7 mm Phillips #000 screw

This 1.7 mm screw tends to not be attracted to a magnetized screwdriver. Take care not to lose it when removing.

It is especially important to keep track of your screws in this step for reassembly. Accidentally using the 1.3 mm screw or one of the 1.7 mm screws in the bottom right hole will result in significant damage to the logic board causing the phone to no longer boot properly.

Be careful not to over-tighten the screws, and don't force them. If they don't fit easily when you are securing them, they may be the wrong size.
