Introduction

You’ll need replacement adhesive to reattach the rear glass when reassembling the device. Your device will function normally, but will most likely lose its IP (Ingress Protection) rating.

What you need

Step 1

              Heat the rear glass

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 display and internal battery are both susceptible to heat damage.

Step 2

              Insert an opening pick

Secure a suction handle to the bottom edge of the rear glass, as close to the edge as possible.
If the rear glass 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.
Lift the rear glass with the suction handle to create a small gap between the back cover and the frame.
If you’re having 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.
Slide the opening pick to the bottom right corner to slice the adhesive.
Leave the opening pick in place to prevent the adhesive from resealing.
