When closing the two parts of the case back, ensure that the levers are lined up/interlocked properly.

The two case pieces will press / snap back together but it can take a few minutes to get everything lined up, especially at that one area with the extra molded plastic.

With the case snapped back together you can proceed with putting the small screw back in and placing the yellow-barreled cable back into place.

Place the two plastic covers back on the assembly so that they are snapped and secure.
