OnePlus 8 Rear Glass Replacement

Introduction

Use this guide to replace a broken rear glass panel on your OnePlus 8.

You'll need replacement adhesive in order to complete this repair.

Note: Retaining water resistance after the repair will depend on how precisely the adhesive is reapplied, but your device will lose its IP (Ingress Protection) rating. However, only the T-Mobile (IN2017) and Verizon (IN2019) models offer IP ratings.

What you need

Step 1 Heat the rear glass

Power off your phone and unplug any cables.
Heat an iOpener and apply it to the rear glass for two minutes.
You can also use a hair dryer, heat gun, or hot plate—but extreme heat can damage the display and internal battery, so proceed with care.

Apply a suction handle to the center of the bottom edge of the rear glass, as close to the edge as possible.
If your display is badly cracked, cover it with a layer of clear packing tape to help the suction cup adhere. Alternatively, you can pull using very strong tape instead of a suction cup. If all else fails, try supergluing the suction cup to the broken screen.
Pull up on the suction handle with strong, steady force to create a gap between the rear glass and frame.
Insert an opening pick into the gap.

After installing the rear glass, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond.
