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

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.

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.

-
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.
-

-
Lift and remove the back cover.

Now is a good time to test your phone before sealing it up. Power it on and check that it works. Power it back down before you continue reassembly.
-
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.

Place the back cover onto the frame and firmly squeeze around the perimeter to reengage all the clips.

Use a T3 Torx screwdriver to remove the two screws securing the battery connector cover.

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.
