Introduction
Use this guide to remove or replace the charging port and main flex cable assembly in the Huawei P30 Pro.
Opening the Huawei P30 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.

Insert an opening pick into the gap.

Slide the opening pick to the bottom right corner.
