  1. Switch off your phone.
    • Switch off your phone.

    • Heat an iOpener to loosen the adhesive beneath the rear glass. Apply the iOpener for at least two minutes. You might want to repeat this step several times during the rear glass removal.

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

  2. Apply a suction cup to the back of the phone, as close as possible to the center of the bottom edge. If the back cover is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed. Pull on the suction cup to create a gap between the rear glass and the frame.
