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.

You can use the back casing as a screw tray for the battery, so keep it close.
