Liberty Firmware Update Troubleshooting

Fixing incomplete firmware updates

Problem description:
The firmware update process freezes or gets stuck at the 'Head load completed' stage in Divesoft Center, preventing the update from completing.

Possible causes:

  • Partial firmware corruption.
  • Unstable USB or Bluetooth link.
  • Outdated firmware package (always download the latest version from the official Divesoft website before updating).

Step-by-step troubleshooting:

Before starting: Allow at least 3–5 minutes for the update to progress past 'Head load completed' before assuming it is frozen.

  1. If the update fails over Bluetooth before reaching 100%, retry the update. If it fails again immediately, restart the Liberty device and then retry.
  2. If the update repeatedly fails over Bluetooth, switch to a USB connection and attempt the update via Divesoft Center.
  3. Restart your computer, the Liberty head unit, and all handsets before retrying the update.
  4. If the issue persists, note all steps attempted and contact Divesoft Support for further assistance.
