Redmi Note 9 Pro Screen Replacement

필요한 것

  1. Redmi Note 9 Pro Screen Replacement, Heat the rear glass: 1 단계, 이미지 1/1
    • 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.

    • 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.

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 these instructions in reverse order.

The best way to secure the new screen is to apply a sheet of custom-cut double-sided tape to the back of the screen.

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

Man sollte vor dem zusammen bauen dringend drauf achten, dass auch Verbindungen die man nicht gelöst hat, wie z.b. Kabelverbindung zum unteren Lautsprecher, wirklich richtig sitzen, sonst darf man nach dem zu kleben feststellen dass der untere Lautsprecher nicht funktioniert 🤣😅😉😡😡😃😃

Welche Art von Klebstoff wird da verwendet, um das neue Display einzukleben? Und es gibt Screens, bei denen zusätzlich ein Glas mit dabei ist, was sind da die Unterschiede und wie werden die montiert?
