Use this guide to remove the back panel to access the components inside.
Remove the battery by placing your thumb on the buttom flap and sliding the release button away from the side the lens is on. (The screwdriver is simply used as a reference point, no screws need to be removed)
Charge the battery for 60-90 minutes if your battery is dead.
Unscrew the 3mm long cover screws at the corners of the camera using a #00 Philips Screwdriver.
Unscrew the 2mm long screws securing the sides of the camera which holds the back panel. Use the same screwdriver.
Detach the ribbons using your thumb, sliding them out of their slots.
