Use an opening tool to separate the rear plate from the phone.

Firmly press the opening tool into the gap between the front glass and rear plate. This gap is located on all sides of the phone.

If the opening tool is not working, try using your fingernails on the side of the phone. Once a small area of the rear plate is released, continue to use the opening tool.

Run the opening tool around the entire phone separating the rear plate from the frame.
