Step 2

Insert a plastic opening tool in the small crevasse between the screen and the back panel.
Pry the screen away from the back panel.
Repeat this on each edge of the device.
We found it helpful to leave multiple plastic opening tools wedged in the crevasse to prevent it from closing.
This requires heavy force. The back of the device is attached with an adhesive. If the back panel is too hard to remove, use the iOpener.

Step 3

After using the plastic opening tools, pry the device open with your hands.
Remove the back panel from the screen.
