OnePlus 8 Daughterboard Replacement

Introduction

Use this guide to replace the daughterboard in your OnePlus 8.

You'll need replacement adhesive for the rear glass 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

  1. OnePlus 8 Daughterboard Replacement, Heat the rear glass: step 1, image 1 of 1

    • 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.
