Heat an iOpener and apply it to the same edge of the phone for two minutes.

Apply a suction cup to the back of the phone, as close to the center of the right edge as possible (where the adhesive is narrowest).

Pull on the suction cup with strong, steady force to create a gap between the back cover and the frame.

Insert the point of an opening pick into the gap.

Due to tight tolerances and strong adhesive, multiple attempts may be necessary to create a gap for the opening pick.

If you are having trouble creating a gap, the adhesive isn't weakened enough. Make sure you have heated the edge until just barely too hot to touch try this step again.

You can try applying a few drops of high concentration (over 90%) isopropyl alcohol into the seam to help loosen the adhesive.

Do not apply excessive force with the pick, or you will risk cracking the back cover glass.
