Starting at a bottom corner, use the spudger to separate the rear case from the front display.

Move the spudger towards the top on both sides. The plastic opening tool is easier to use for this step.

Be careful when detaching the top. Free each side, stopping short of the center of the cover. Apply backward pressure on both corners with a finger applying pressure on the center, and slide the whole back cover toward the bottom of the device. Note: forcing the cover can result in cracked plastic.
