简介

转到步骤 1

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.

步骤 1 Rear Glass Replacement

Huawei P20 Pro Screen Replacement, Rear Glass Replacement: 步骤 1 中的图像 1，1

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.

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.

Bonjour à toute l'équipe, déjà un grand merci pour votre travail, j'adore vraiment l'état d'esprit.

J'en suis à l'étape 1 et comme ma vitre arrière est cassé, la ventouse n'adhère pas.

Donc plan B, comme suggéré malheureusement ma cyanolite ne semble pas adhérer sur le verre, j'essaie avec une bonne colle à chaussure car Trés solide et je laisse sécher la nuit en légère pression, j'espère avoir un minimum de prise afin de glisser les médiators mais le verre est bien brisé et j'ai un peu peur que ça parte en morceaux, croisons les doigts 🤞

Je vous dirais pour la suite 😉

Salut à l'équipe, vous faites un travail formidable, merci beaucoup

步骤 2

Huawei P20 Pro Screen Replacement: 步骤 2 中的图像 3，3

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

编辑

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.

Stefano Restuccia - 2019年9月24日回复

It is better to put a peak on the side because the side opens first than the bottom of the phone.

이정일 - 2020年6月15日回复

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.

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.
Try your best not to deform the battery during the following removal process. Soft-shell lithium-ion batteries can leak dangerous chemicals, catch fire, or even explode if damaged. Do not use excessive force or pry at the battery with metal tools.
Insert the flat end of a spudger at the top left corner of the battery and start to pry it up.
Work your way down the left side of the battery and loosen the adhesive with the spudger.

Do not reinstall a damaged or deformed battery, as doing so is a potential safety hazard. Replace it with a new battery.
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.

Bonjour, le "ôter la batterie " m'a fait rigoler, trois fois chauffer le Iopener pour ramollir la colle et malgré tout, la batterie était tellement bien accrochée qu'elle est maintenant déformé, plier et même percée donc bonne à jeter, j'avais pas prévu de la remplacer mais j'y suis contraint 😑

Merci encore pour ce tutoriel génial 👍

Use the flat end of a spudger to pry up and disconnect the display flex cable at the bottom left of the motherboard.

编辑

步骤 27

Prepare an iOpener and apply it to the display for at least two minutes to loosen the adhesive beneath.
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.

编辑

Bonjour l'équipe, je ne comprends pas pourquoi, l'Iopener n'est pas plus large, ses dimensions ne correspondent à aucun téléphone moderne et la tenue en température est faible, en plus il ne supporte pas les chauffe à répétition.

Peut-être pourriez vous suggèrer le décapeur thermique et nous donner des indications sur les températures à atteindre et les températures maximale...

Simple suggestions😉

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.
Make sure you get in the right gap between the display and the plastic bezel. Do not pry between the bezel and the midframe.

编辑

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

C encore moi, j'ai fini par pouvoir insérer un médiator après de nombreuses reprises à 25 centimetres de mon décapeur thermique réglé au minimum après 10 minutes de chauffe et en insérant au préalable sur 3 MM un cuter très petit, si ça peut vous servir 😉

J'ai juste fait la place d'insérer mon 1er médiator et le reste à été tout seul, colle bien ramolli

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

Wie komme ich den Homebutton wieder fest.

Nach der Reparatur hängt dieser leicht nach vorne raus. Brauche ich einen speziellen Kleber oder geht auch klassischer Sekundenkleber von UHU?

Sleepy Lex - 2025年1月3日回复

结论

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.

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,

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??

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 - 2023年5月22日

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.

Alex - 2023年5月22日

Bravo à vous et merci. Sans ce tuto je n'aurai pas osé.

Ça m'aura coûté moins de 100€ et moins de 4h.

J'ai 0,4mm d'épaisseur de plus qu'avant mais tout fonctionne parfaitement 👍

Merci merci
