Introduction

In order to replace the rear glass you need to transfer the finger print reader from your old rear glass to the new one. In case your replacement part has a new fingerprint reader installed this is not necessary.

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

What you need

Step 1

Before you begin, switch off your phone.
Apply a heated iOpener to the back of the phone to loosen the adhesive beneath the back cover. Apply the iOpener for at least two minutes.

Step 2

Secure a suction handle to the bottom of the rear glass, as close to the edge as possible.
If the phone’s 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 glass and the frame.
Insert an opening pick into the gap.
If you have trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
Slide the opening pick to the bottom right corner.
