Huawei P20 Pro Interconnect Cable with Charging Port Replacement

Difficulty

Moderate

Steps

Time Required

45 minutes - 1 hour

Introduction

Use this guide to remove or replace the interconnect cable including the charging port in 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.

Tools

Step 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.

Step 2

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.

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.

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

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.

Step 3

Insert a second opening pick and slide it to the bottom left corner. Leave it there to prevent the adhesive from resealing.

Step 4

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.

Step 5

In case you're having trouble to cut the adhesive, reapply the iOpener for another minute to loosen it.
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.

Step 6

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.
Don't open the phone all the way yet. The proximity sensor flex cable is still connected to the motherboard.

Step 7

Carefully lift the rear glass until you can reach the connector of the proximity sensor flex cable next to the rear camera assembly.

Step 8

Use the flat end of a spudger to pry up and disconnect the proximity sensor flex cable.

Step 9

Remove the rear glass.
Before installing fresh adhesive and reassembly, remove any remaining adhesive from the phone, and clean the glued areas with isopropyl alcohol and a lint-free cloth.

Step 10

Remove the nine Phillips #00 screws (3.4 mm length).

Step 11

Insert an opening pick under the left side of the motherboard cover that includes the NFC.
Slide the opening pick towards the top left corner of the phone and twist it to pry the cover out of its plastic clamps.

Step 12

Repeat the previous process on the right side and twist the opening pick to pry up the motherboard cover.

Step 13

Remove the motherboard cover.

Porque cuando desconectas el nfc no vuelve a funcionar?

Hallo ich habe alles nach der Anleitung gemacht. Nun geht der Connector wieder, aber ich habe das Problem, das ich innerhalb von Gebäuden kein Netz mehr habe. Außerhalb von Gebäuden kein Problem. Was kann ich tun? Das Antennenkabel weißt auf den ersten Blick keine Beschädigungen auf…

hola, y.. ¿cuales tipos de pegamentos recomiendan para volver a pegar la tapa trasera? Use Poxiran( cemento de contacto) pero no se adhiere bien al plastico

Hi, you can use double sided adhesive tape like this one or even pre-cut adhesive for the rear case if you get one for your device on the internet. Poxi-ran could work too after removing old adhesive and if applied carefully only on those areas where there was adhesive.

dear friend hi. thanks for your perfect explanation but in my case, i wasn’t so able to fix my Huawei P20 charging socket and battery replacement that i had to do. The problem that i have is that the phone now is not charging. when i connect the cable to charge the phone the first 2 sec looks like is charging but after that is stopped. One more problem that i have is when the phone is into the charger and you turn it of is doing a restart by itself. The speaker is working and also the data transfer. Have you ever seen this kind o issue before?
