Introduction
Use this guide to replace a defective or cracked OLED screen and digitizer in the Huawei P20 Pro.
Note: This guide instructs you to replace only the display while leaving the original frame and motherboard in place. However, some replacement screens for this phone come pre-installed in a new frame (a.k.a. chassis), which requires a very different procedure—transplanting all your phone's internals. Make sure you have the correct part before starting this guide.
Opening the Huawei P20 Pro will damage the waterproof seals on the device. If you do not replace the adhesive seals, your phone will function normally but will lose its water protection.
Do not reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new battery.
Before disassembling your phone, discharge the battery below 25%. If your battery is swollen, do not heat your phone. Swollen batteries can be very dangerous, so wear eye protection and exercise with caution, or take it to a professional if you're not sure how to proceed.
You’ll need adhesive glue to reattach components when reassembling the device.
What you need
-
-
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.
-
-
-
Press a suction cup onto the rear glass close to the bottom edge of the phone.
-
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.
-
-
-
-
Use the flat end of a spudger to pry up and disconnect the battery flex cable.
-
-
-
Remove the five Phillips #00 screws (3.4 mm length).
-
-
-
Use an iOpener to loosen the adhesive beneath the battery. Apply the iOpener on the display for at least two minutes.
-
In the following step, only apply the spudger in the areas marked in red, which is where the battery adhesive is located.
-
Avoid the orange area where the display flex cable is running.
-
-
-
Use the flat end of a spudger to pry up and disconnect the display flex cable at the bottom left of the motherboard.
-
-
-
Prepare an iOpener and apply it to the display for at least two minutes to loosen the adhesive beneath.
-
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.
-
-
-
Use an opening pick to open the black flap of the home button ZIF connector.
-
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.

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.
*Throws happiness at screen* Here you go man
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,
ma compagne a cassé son p20 pro.On annoncait 340 € à réparer.Je trouvais ca beaucoup, mais avec la pièce à 220 €, et 1 à 3h de travail, ca s’explique…+ le cout des outils …Il se trouve à 300 € en 2e main ou fin de série….Mais si on est bricoleur, ca peut etre drole. Courage, et merci pour ce tuto !
