Remove the 10 J00 screws holding the back case assembly to the camera body.

There is another sneaky screw under the right-side thumb grip. Use an opening pick or tweezers to get under the adhesive-secured grip to pull it slightly away from the body to access the screw. The adhesive should remain adhered to the grip, and it should go back in place without any marks.

The memory card slot cover will come off, separate from the back. This allows the mainboard to come out without catching anything.
