Introduction

You’ll need replacement adhesive to reattach components when reassembling the device.

What you need

Step 1

              Heat the rear glass
  • Prepare an iOpener and apply it to the back cover 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.
  • 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.

  • Insert a third opening pick at the bottom left corner of your phone.
  • Slide the opening pick along the left edge of your phone to slice the adhesive.
  • Leave the opening pick in the top left corner to prevent the adhesive from resealing.

If possible, turn on your device and test your repair before installing new adhesive and resealing.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow these instructions in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.
