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

    • 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.

    • Once the screen is warm to touch, apply a suction cup to the bottom edge of the phone.

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

    • Insert an opening pick in the gap between the midframe and the screen.

    • In case you only want to replace the display glass but not the LCD and digitizer you need to be especially carful during the next step. There's a small cable at the bottom right end of the LCD which is very fragile. Only slide with the very tip of your opening pick (about 1-2 mm).

    • Slide the opening pick to the bottom right corner of the screen to slice its adhesive. Leave the opening pick in place to prevent the adhesive from resealing.

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.

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.
