Introduction

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

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.

    • 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 a delicate cable still connects it to your phone.
