HMD Skyline Charging Board Replacement

Introduction

Follow this guide to replace the charging board in your HMD Skyline smartphone.

The USB-C charging port and storage expansion/SIM tray are attached to the charging board. If the USB‑C port breaks, you have problems charging your phone, or the SIM tray isn't inserting correctly, you'll need to replace the entire charging board.

What you need

  1. HMD Skyline Charging Board Replacement, Prepare your phone for disassembly: step 1, image 1 of 1

    • Let your phone's battery drain below 25% before starting this repair. A charged lithium‑ion battery may catch fire if damaged.

    • Unplug all cables and completely power off your phone.

    • Firmly press a SIM eject tool, bit, or straightened paper clip into the SIM tray hole on the bottom edge of your phone until the tray ejects.

    • Remove the SIM card tray.

    • A thin rubber gasket around the SIM tray provides water and dust protection. If this gasket is damaged or missing, replace the gasket or the entire SIM tray to protect your phone's internal components.

    • A screw‑driven camshaft in the bottom left corner pushes the back cover away from the phone, creating a gap to begin separating the cover.

    • With the back cover facing up, use a T3 Torx screwdriver to turn the screw in the bottom edge counterclockwise until the back cover pops up.

    • Before separating the back cover, note the following:

    • There's a seam just under the back cover panel. Don't insert your tool here.

    • Insert your tool completely under the back cover, so it's between the frame and the underside of the back cover.

    • Insert an opening pick under the bottom left corner of the back cover and slide it along the bottom edge to release the clips and separate the adhesive.

    • You should feel and hear the back cover clips release. If you don't, insert the pick deeper and try again.

    • Make sure you remove all liners from the underside.

    • Use the flat end of a spudger to press the small cable above the wireless charging coil into place over its alignment posts.

    • Make sure the tweezer arm is as close to the head of the connector as possible.

    • Repeat the process to disconnect the other coaxial connector.

    • During reassembly:

    • Use the markings on the board to make sure the cables get connected to the correct socket—B for black and W for white.

    • Hold the metal neck of the antenna connector with a pair of tweezers and align the head over its socket on the board.

    • Use the flat end of a spudger to press straight down on the connector head—it should snap into place. If you're having trouble, reposition the head and try again. Don't try to force the connector into place, or you risk damaging the charging board.
