    • Prepare an iOpener and apply it to the rear glass for at least two minutes to loosen the adhesive underneath.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the screen and internal battery are both susceptible to heat damage.

    • Secure a suction handle to the right edge of the rear glass, as close to the edge as possible.

    • Lift the rear glass with the suction handle to create a small gap between the rear glass and the frame.

    • In case you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

    • Insert an opening pick into the gap you created.
