Firmware Update - Analyzer Not Powering On

Recovering Analyzers that won't power on after firmware update

 

Use this guide if your Divesoft analyzer is unresponsive or stuck after a firmware update. Follow the steps below to diagnose and recover your device.

Possible Causes:

  • Incomplete firmware update
  • Wrong firmware version installed
  • Depleted battery

Step-by-step troubleshooting:

  • For firmware update, navigate to the Divesoft Center webpage and follow the instructions on how to enter bootloader mode on your Analyzer.
    • Write down your Analyzer HW version (shown on the startup screen), you will need it in next steps.
    • Enter the bootloader mode first - the method depends on your HW version:
      • HW 4.x and newer: press CAL+MENU+ON/OFF together. The display shows BOOTLOADER.
      • HW 2.5/3.x (incl. SOLO 3.1): press CAL+MENU+ON/OFF together, then release CAL and MENU but keep holding ON/OFF for the whole update.
      • HW 2.4 and older: insert the programming plug into the system connector (or short the pins in the 9V battery compartment), press and hold ON/OFF, then remove the plug and keep holding ON/OFF.
      • NOTE: On HW 2.x/3.x the display stays blank in all cases the analyzer firmware must not be running.
    • Proceed with the Connect button.
    • [HW 2.x/3.x only] Select appropriate FW by your Analyzer model and HW
      • If you see no FW available, that means the Analyzer has no new FW available. If you are troubleshooting an issue, contact our support with your Analyzer model, HW version, SN so they can provide you with appropriate FW package.
    • Update :)
      • [HW 2.x/3.x] keep holding the ON/OFF button during whole FW update/upload
  • In case of issues, retry the firmware update once more
    • Ensure battery is fully charged before update attempt
    • Use original USB cable and direct computer connection (no USB HUB)
    • Try a different computer or USB port

When to contact service: If your analyzer remains unresponsive after completing the recovery steps above, contact Divesoft support — professional reprogramming may be required.
