    • Secure a suction handle to the bottom of the back cover, as close to the edge as possible.

    • Lift the back cover with the suction handle to create a small gap between the cover and the frame.

    • Insert an opening pick into the gap.

    • If you have trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
