Open the MicroSD Card Reader door. It will assist when opening the case as there is a snap point directly beside this door.

Starting from the corner, slide your spudger down and in at a steep angle. You will hear a click as the snap loosens. Slid the spudger inside the case and turn 90° to the left or the right to release the snap.

Begin by slowly working your way around the case. If you come across a section that does not release as easy, leave it and go the opposite direction around the case. Eventually the pressure will release and the back case will pop off.
