    • The back cover of the Redmi Note 9 is held in place by plastic clips and adhesive. It might require some force to release the plastic clips.

    • Prepare an iOpener and apply it to the back cover for at least two minutes to loosen the adhesive underneath.

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

    • If the screen 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 phone assembly with the suction handle to create a small gap between the assembly and the back cover.

    • 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 in a steep angle into the gap you created. This might require some force.

    • Slide the opening pick to the bottom right corner to slice the adhesive and release the plastic clips holding the back cover in place.

결론

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 the above steps in reverse order.

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

Repair didn’t go as planned? Try some basic troubleshooting, or ask our Answers community for help.

Yesterday I completed replacing the loudspeaker for my note 9 using the instructions in this guide.

Although I had to reheat the i opener a few times I found it very useful to use a thermometer to check on the build up of heat in the phone.

Once I got the back off it was just a matter of following the instructions step by step.

I think the instructions are excellent!

Thank you!

Hello all, I Just replaced the loudspeaker and It worked for a few times. It works intermittently. It seems that something it's not connected firmly, but I double checked all connections and they seem ok. What else can I check?

TIA
