Introduction

Use this guide to remove the rear glass of the Sony Xperia Z4.

Sony Xperia Z4 Rear Cover Adhesive

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 back cover, as close to the edge as possible.
Lift the back cover with the suction handle to create a small gap between the cover 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 left corner.

Step 3

Insert a second opening pick and slide it to the bottom right corner to cut the adhesive.
Leave the opening picks in place to prevent the adhesive from resealing.

Step 4

Insert a third opening pick at the bottom left corner.
In the next few steps whilst cutting around the rear camera make sure you only use the tip of the opening pick to avoid smearing the lens or damaging the camera.
Start to slide the tip of the opening pick from the bottom left corner along the side of the phone to cut the adhesive.
Leave the opening pick in its place at the top left corner to prevent the adhesive from resealing.

Step 5

If the adhesive becomes hard to cut it most likely cooled down. Use your iOpener to reheat it.
Insert a fourth opening pick under the top left corner of the back cover.
Slide the opening pick along the top edge of the phone to cut the adhesive.
Leave the opening pick in the top right corner to prevent the adhesive from resealing.

Step 6

Insert a fifth opening pick at the top right corner of the phone.
Slide the opening pick along the right side to cut the remaining adhesive.

Step 7

Lift and remove the back cover.
After installing the back cover, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond, such as by placing it under a stack of heavy books.
