はじめに

Use this guide to remove or replace the charging port and main flex cable assembly in the Huawei P20.

Opening the Huawei P20 will damage the splash and dust protection seals on the device. If you do not replace the adhesive seals, your phone will function normally but will lose its protection.

You’ll need replacement adhesive to reattach components when reassembling the device.

Secure a suction handle to the bottom of the back cover, as close to the edge as possible.
If the phone's rear glass is cracked, the suction handle may not stick. Try lifting it with strong tape, or superglue the suction handle in place and allow it to cure so you can proceed.
Lift the back cover with the suction handle to create a small gap between the cover and the frame.
Insert an opening pick into the gap.
If you have trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
