  1. Huawei P20 Pro Interconnect Cable with Charging Port Replacement, Rear Glass Replacement: step 1, image 1 of 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.

    • 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.

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

mar mar mar - Reply

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?
