    • Switch off your phone.

    • Use an iOpener to loosen the adhesive beneath the rear glass. Apply the iOpener for at least two minutes. You might want to repeat this step several times during the back cover removal.

    • The adhesive of the Huawei P20 Pro is of moderate strength, however a hair dryer, heat gun, or hot plate may also be used if you aren't able to open the device with the iOpener. Be careful not to overheat the phone—the OLED display and internal battery are both susceptible to heat damage.

    • Lift the bottom edge with the suction cup, opening a slight gap between the rear glass and the frame.

    • Insert an opening pick in the gap and slide it to the bottom right corner. Leave it there to prevent the adhesive from resealing.

    • In case you have trouble to pry up the battery the adhesive may not be loose enough. You can apply some isopropyl alcohol under each corner of the battery and allow it to penetrate for about two minutes to help weaken the adhesive.

    • Before installing a new battery remove any remaining adhesive from the phone, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

    • 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 for 5-10 seconds.

    • You may need to reheat and reapply the iOpener several times to get the phone warm enough on all sides. Follow the iOpener instructions to avoid overheating.

    • If your display glass is cracked, keep further breakage contained and prevent bodily harm during your repair by taping over the glass.

    • Lay overlapping strips of clear packing tape over the display until the whole face is covered.

    • This will keep glass shards contained and provide structural integrity when prying and lifting the display.

    • Wear safety glasses to protect your eyes from any glass shaken free during the repair.

Conclusão

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.

The best way to secure the new screen is with adhesive glue. Apply the glue to the plastic frame, then carefully feed the display cable through its gap, align the screen and press it into place.

To reassemble your device, follow these instructions in reverse order.

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.

Most detailed guide I’ve personally seen. And I love the detailed gif like steps, which are positively the best way to explain something. Hands down. Love it. Only the important stuff without the fluff easily accessible for back and forth.

Can’t stress enough how much I want you to keep using this formula.

I need some help - I have the new LCD but it’s already in its housing. I am confused how to transfer all the existing parts (cameras, boards etc) onto the new frame! CL

Bonjour,

L’introduction du tuto stipule : “Ouvrir le Huawei P20 Pro endommagera les joints étanches de l'appareil. Si vous ne les remplacez pas, votre téléphone continuera à fonctionner normalement, mais ne sera plus étanche à l'eau. “

Comment remplacer ces joints ? Un produit en particulier ? Est-ce la colle qui fait office de joint étanche ?

Merci pour les infos,

Aurélien C - Responder

Courage, et merci pour ce tuto !
