    • Before you begin, switch off your phone.

    • Apply a heated iOpener to the back of the phone to loosen the adhesive beneath the back cover. Apply the iOpener for at least two minutes.

    Hi guys fingerprint sensor on my Huawei p20 Pro stopped working but I didnt want to attempt screen removal as the chances of damaging the screen were high, but what if I could remove and replace the sensor without removing the screen at £6.00 a pop on ebay for a replacement sensor against a ton plus for a new screen, I opted to take a chance with the sensor, so I removed battery cover glass then all removable parts in the sensor area, once removed I could see a big enough gap to feed the sensor through, now the tricky part I smeared vaseline on the area of the sensor ribbon that fitted between frame and screen and carefully slid it between the frame and screen, now all that was left was to connect the sensor to the connector, there was no way that I could see to slide the ribbon under the frame to connect it so I laid it over that part of frame and connected it to the screen, before I replaced the sensor the phone wouldn't recognise it at all so I was relieved that it detected it now. Works perfectly.

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

    • If the phone's 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 back cover with the suction handle to create a small gap between the cover and the frame.

    • Insert an opening pick into the gap.

    • If you have trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.

    • Slide the opening pick to the bottom right corner.

    • Insert a second opening pick and slide it to the bottom left corner to cut the adhesive.

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

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

    • In the next few steps whilst cutting around the power button and rear camera make sure you only use the tip of the opening pick to avoid cutting the cable, smearing the lens or damaging the camera.

    • Start to slide the tip of the opening pick from the bottom left corner along the side of the phone to cut the adhesive.

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

    • Use a pair of tweezers to peel the black tape next to the rear camera off the motherboard cover.

    Do I have to conserve that tape?

    Belén Enriquez - Réponse

    Hi Belén,

    the tape is more of a protective film and doesn’t have a function which would affect the phone when not reapplied.

Conclusion

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

Secure the new battery with pre-cut adhesive or double-sided adhesive tape. In order to position it correctly, apply the new adhesive into the phone at the places where the old adhesive was located, not directly onto the battery. Press the new battery firmly into place.

To reassemble your device, follow these instructions in reverse order. Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).

For optimal performance, calibrate your newly installed battery: Charge it to 100%, and keep charging it for at least two more hours. Then, use it until it shuts off due to low battery. Finally, charge it uninterrupted to 100%

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

El mío no abre ni con soplete, he aplicado calor con secador del pelo, las cuñas se rompen, la ventosa se despega... no se mueve ni una micra. Al que inventó el USB C habría que colgarlo de los dedos de los pies y lo de las cacharros de cientos de euros cerrados como una caja de seguridad lo mismo.

Thank you so much!!!

Worked perfectly. Step 15 backwards is the biggest challenge.
