Flip your device so that the long side without the buttons faces you.

Insert the Plastic Opening Tool between the silver back plate and the screen about one inch from the corner of the device on either side.

Using the Plastic Opening Tool, pry open the screen until it unsnaps from the back plate.

Work your way down the edge of the device, unsnapping all locations where the screen meets the silver back plate.

Go around the corners with the Plastic Opening Tool and unsnap additional snap-in locations as necessary.
