Huawei Mate 20 Pro Daughterboard Cover Replacement
Use this guide to remove or replace the daughterboard cover in your Huawei Mate 20 Pro.
Opening the Huawei Mate 20 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.

Before you begin, switch off your phone.

Apply a heated iOpener to the back of the phone to loosen the adhesive beneath the back cover. Apply the iOpener for at least two minutes.

If the adhesive becomes hard to cut, it has most likely cooled down. Use your iOpener to reheat it.

Insert a fourth opening pick under the top left corner of the back cover.
-
Slide the opening pick along the top edge of the phone to cut the adhesive.
-
Leave the opening pick in the top right corner to prevent the adhesive from resealing.

Hi there.... My huawei mate 20 pro was water damaged!!! After a while its LCD was displaying green lines and in no time it went blank, but surprisingly the phone works and still receives notifications and incoming calls. I could even answer calls in a blank screen by pretending to swipe as if its on. My question before i buy a replacement screen . Is the LCD really damaged or its the logic board ? This might help me decide on how to proceed with it.
