OnePlus 9 5G Daughterboard Replacement

简介

Use this guide to replace the daughterboard in your OnePlus 9 5G.

You'll need replacement adhesive for the rear glass in order to complete this repair.

Note: Retaining water resistance after the repair depends on how clean the mating surfaces are and how accurately the adhesive is reapplied. Your device will lose its factory-given IP (Ingress Protection) rating, however, only the T-Mobile versions of the OnePlus 9 5G offer an IP rating.

  3. OnePlus 9 5G Daughterboard Replacement, Loosen the rear glass: 步骤 3 中的图像 1，1

    • Completely power off your phone before you begin.

    • Prepare an iOpener and apply it to the rear glass for at least three 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.

    • Apply a suction handle to the rear glass, as close to the bottom edge as possible.

    • If your rear glass is badly cracked, covering it with a layer of clear packing tape may allow the suction handle to adhere. Alternatively, very strong tape may be used instead of the suction handle. If all else fails, you can superglue the suction handle to the broken rear glass.

    • Pull up on the suction handle with strong, steady force to create a gap between the glass and the frame.

    • If you have trouble creating a gap, apply more heat to further soften the adhesive.

    • Insert an opening pick into the gap.

结论

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 you install it.

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

During reassembly, apply new adhesive where it's necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

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