    • Once the screen is warm to the touch, apply a suction cup near the top edge of the phone right under the earpiece speaker.

    • If the phone's screen is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.

    • Pull up the suction cup, and insert the tip of an opening pick under the display where the earpiece speaker is located.

    • Slide the opening pick to the top left corner of the phone to cut the adhesive.

    • If cutting becomes too difficult, reheat and reapply the iOpener.

    • Slide the opening pick from the top right corner down the right edge of the phone and cut the adhesive with it.

    • While cutting, make sure the pick slides under the display panel and not just between the display and the front glass.

    • Slide the opening pick around the bottom right corner.

    • Carefully thread the display cable at the top and the fingerprint sensor cable on the bottom through their gaps in the midframe.

    • Remove the LCD and digitizer.

    • Remove any remaining adhesive from the midframe, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

    • In case your new LCD and digitizer doesn't include the fingerprint sensor, you will need to continue with the fingerprint sensor guide to transfer it to the new LCD and digitizer.

    • Carefully pry off the fingerprint sensor by lifting it with the edge of an opening pick.

    • Remove the fingerprint sensor with a pair of tweezers.

    • There's a small rubber gasket around the fingerprint sensor which you might need to transfer to your replacement sensor.

Conclusión

The best way to secure the new screen is with a sheet of custom-cut double-sided tape. Apply the tape to the back of the screen, then carefully feed the display cable through the frame. Align the screen and press it into place.

To reassemble your device, follow these instructions in reverse order and reapply adhesive where it’s necessary.

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

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