Use a Phillips #1 screwdriver to remove the following screws:

One 5.5mm Phillips screw holding the screen assembly.

Two 8.0mm Phillips screws holding the motherboard.

Two 6.0mm Phillips screws holding the game cartridge slot.

One of these screws also holds a black plastic bracket for the front camera, and the bracket is loose once the screw is removed. Set the bracket aside if it falls out.

Remember to replace the bracket during this step of reassembly if it was removed.

Three 6.0mm Phillips screws holding the auxiliary board.

Be careful not to damage the gray ribbon cable connecting the auxiliary board when removing these three screws.
