Using a Phillips #000 screwdriver, remove all 18 of the 4mm screws.

With the blue plastic opening tool, gently wedge the tool between the screen and the gray frame until you feel resistance.

Do not force the frame off because you can break off the teeth securing the frame to the screen.

Using your opening tool, push in the teeth towards the center of the device, and gently pull off the frame.

The gray frame will still be connected to the device by a pair of wires from the motherboard to the speaker.
