Insert the flat edge of a metal spudger in the seam between the adapter body and the plastic casing. Move the spudger into one of the corners.
Push down on the spudger to separate the casing from the adapter until you hear a click and the casing stays open on that side.
Do the same to the other side until the casing comes off.
When reassembling, first align the headphone jack in the back of the adapter body with the hole in the casing, then align the tabs on the floor of the casing with the holes in the bottom of the adapter body.
Remove three 5.0 mm T5 Security Torx screws along the edges of the controller housing.
Remove two 8.0 mm T5 Security Torx screws near the top-center of the adapter.
With your fingers, carefully lift the adapter housing from the button panel.
Be careful not to yank the wires connecting the two halves of the circuit board.
Pull back on the controller USB connector with your interview to separate the main adapter circuit board from the rubber mold in the button panel.
Remove the two 5.5 mm Phillips #00 screws connecting the smaller circuit board to the adapter housing. The smaller circuit board should come right off.
One of the screws is located beneath the connecting wires, so you may have to move the main circuit board around until you can see the screw.
