Einleitung

Use this guide to replace the loudspeaker on your Xiaomi Redmi Note 9 Pro.

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

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

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

    • If the 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 back cover and the frame.

    • In case you have trouble creating a gap, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

    • Insert an opening pick into the gap you created.

    • Slide the opening pick to the bottom right corner to slice the adhesive.

    • Leave the opening pick in place to prevent the adhesive from resealing.

    • Insert a second opening pick at the bottom edge of your phone.

    • Slide the opening pick to the bottom left corner to slice the adhesive.

    • Leave the opening picks in place to prevent the adhesive from resealing.

    • If the adhesive becomes hard to cut, it has most likely cooled down. Use your iOpener for one to two minutes to reheat it.

    • Insert a third opening pick at the bottom left corner of your phone.

    • Slide the opening pick along the left edge of your phone to slice the adhesive.

    • Leave the opening pick in the top left corner to prevent the adhesive from resealing.

    • Remove the rear glass.

    • Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

    • Secure the new rear glass with pre-cut adhesive or double-sided adhesive tape. After installing the rear glass, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.

    • Use a Phillips screwdriver to remove the eleven 3.9 mm-long screws securing the motherboard cover.

Abschluss

If possible, turn on your device and test your repair before installing new adhesive and resealing.

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 installing.

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

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