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.
if the back cover is not broken, i’d suggest NOT to use an opening pick as if the phone was not heated enough, you may crack the glass on the edges. better use the iPlastix, it is thinner and less stressful for the glass.
I have to agree that is is much easier to start opening from the side. Do read the rest of the guide though, to make sure you won’t hit something when opening it from the side.

Remove the rear glass.
Das mit den Klebstreifen funktioniert nicht. Ich habe die Tube E6000 in die Dichtungen eingeklebt und so das Smartphone wieder zusammengesetzt.

-
Remove the motherboard cover.

-
Use the flat end of a spudger to pry up and disconnect the battery flex cable.
Das Flachbandkabel kann einen Zentimeter zu lange sein. Ich musste ihn 2 mal falten, um beim Einbau die Steckerbuchse wieder zu treffen.
-
-
-
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.
-
-
-
Once the screen is warm to the touch, apply a suction cup to the upper edge of the phone.
-
Pull the suction cup upwards and insert an opening pick in the gap between the display glass and the plastic bezel. Start to cut the adhesive by sliding the opening pick to the top left corner.
There will be 2 gaps one under the screen glass(the one you should open) the secod notch down is where a fragile plastic frame is. Stay away from it and use the upper notch
-
-
-
Use a pair of tweezers to peel the display flex cable free from the frame.
-
Thread the display flex cable through the gap in the frame and remove the display.
after this part, even after heating the screen it didn’t come apart in one shot, i had my digitizer, led, and protective all apart and still no access to remove the display flex cable, tore a cable connecting to the screen and now my phone is trash. somehow you managed to bypass this part and magically go to the part where you can see the home button? not happy. “Remove Display” you make it seem so easy yet this is the part that destroyed my phone. Please include the step 33b that we need, thanks

-
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 !
Hello
I have a question.
We done everthing like it is explained. (Thank you for the amazing instruction!)
But now we want to instal the new lcd screen but there is no fixation for the home button (silver thing). And we can remove the old one. Any suggestions?
Hey, did you ever find a solution for this??
Alex -
The silver bit that looks like it's part of the chassis, does actually pop out. Make sure not to bend it!!

Impresionante tutorial. Lo he seguido tal y como se indicaba, y he podido sustituir perfectamente la pantalla y la batería. Un 10. Gracias
Hello,
I´ve just replace the battery and the phone doesn´t not turn on. The screen works and the phone is charging ( i can see the percentage in the screen)
any suggestion? Thanks,
Hey, did you find a solution for this?
My phone is half assembled to test before sealing, and the screen comes on and I can see it charging, including the percentages, however the power button appears to do nothing?
Alex -
Okay, not certain on this however I got it to work.
There appears to be an anti-tamper or open back sensor switch on the main board, located between the screen ribbon cable connection, and the the flash module, right next to the top of the battery. This is a metal clip looking thing, which I pressed down with a blue plastic spudger to make contact with the board, while holding the power button, the phone turned on.
I also had to do this again in order to turn the phone off.

Ich hatte keinen iOpener. Daher hab ich das P20 Pro für ein paar Minuten auf eine Wärmflasche gelegt. Die Klebeschicht konnte relativ schnell gelöst werden.
