Unplug the charger, power down the device, and remove the SD card before beginning.

Insert an opening pick into the seam between the rear case and the screen assembly.

Slide the opening pick around the perimeter, prying periodically, until the screen assembly begins to release.

Insert an opening tool into the gap you created, and continue to pry periodically around the entire perimeter until the screen assembly fully releases.

Be patient and don't pry too hard in any specific place. Excessive force may cause damage to the device.
