Introduction

Use this guide to replace the charging board in your HMD Fusion phone.

The charging board includes the USB-C port and headphone jack. To replace either of the ports, you must replace the entire board.

If you're having issues charging your phone, connecting headphones via the 3.5 mm jack, or if either port is loose, it may be time to replace the charging board.

    • 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 from your phone and completely power it down.

    • Use a T3 Torx screwdriver to remove the sixteen 5.0 mm‑long screws securing the back cover.

    • Use your fingernails, or angled tweezers, to remove any stuck screws.

    • The screws are secured tightly in the back cover, so you might not be able to remove all of them. If you can't remove a few screws, don't worry! Move to the next step and follow the guide normally.

    • During the next four steps, the remaining back cover screws might fall out unexpectedly.

    • To avoid losing screws, you can place a tray, bowl, or Magnetic Project Mat under the phone while you work.

    • Continue sliding the pick around the perimeter of your phone until the back cover is fully unclipped.

    • The corners can be tricky to unclip and may take some force. If you're having trouble, try prying up with the pick.

    • Don't try to fully remove the cover yet, as it's still connected by a delicate cable.
