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

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.
Slide the opening pick to the bottom right corner.

Before installing fresh adhesive and reassembling, remove any remaining adhesive from the phone, and clean the glued areas with isopropyl alcohol and a lint-free cloth.
During reassembly, this is a good point to power on your phone and test all functions before sealing it up. Be sure to power your phone back down completely before you continue working.
Secure the new back cover with pre-cut adhesive or double-sided adhesive tape. After installing the rear glass, apply pressure for several minutes to help the adhesive form a good bond, such as by placing it under a stack of heavy books.
