Introduction
Use this guide to replace a cracked rear glass of the Huawei P20 Pro.
Opening the Huawei P20 Pro will damage the waterproof sealing on the device. If you do not replace the adhesive seals, your phone will function normally but will lose its water-protection.
You’ll need replacement adhesive to reattach components when reassembling the device.
-
-
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.
-
-
-
Insert a second opening pick and slide it to the bottom left corner. Leave it there to prevent the adhesive from resealing.
-
-
-
Insert a third opening pick at the bottom left corner.
-
Slide the tip of the opening pick along the left edge of the phone to cut the adhesive.
-
Leave the opening pick in the top left corner of the phone to prevent the adhesive from resealing.
-
-
-
Insert a fourth opening pick at the top left corner of the phone.
-
Slide the opening pick along the upper edge of the phone to cut the adhesive beneath the rear glass and leave it in the top right corner.
-
-
-
Insert a fifth opening pick at the top right corner of the rear glass.
-
Slide the opening pick along the right edge of the phone to cut the remaining adhesive.
-
-
-
Carefully lift the rear glass until you can reach the connector of the proximity sensor flex cable next to the rear camera assembly.
-
To reassemble your device, follow these instructions in reverse order.
After installing the rear glass, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond, such as by placing it under a stack of heavy books.

Do you suggest any particular kind of adhesive? I always have trouble with these things. Sooner or later, if not immediately, any glass or screen I fit this way always lifts up. The adhesives that come with the parts always seem weak. I try B-7000 glue or/and double sided tape, but still it won’t sit tight.

Hi Smeargle, the options you already tried are also the ones I’d recommend. When applying new double-sided adhesive I’d also suggest slightly heating the glued area and applying some pressure for a few hours (stack of heavy books overnight might do).
Although I understand the steps, why did you not include steps to install the fresh rear glass?

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
