Pre-Update Checklist

  • Single Connection: Connect only one IODD device to your PC at a time.

  • Model Match: Ensure you have downloaded the exact firmware matching your IODD model. If you flash the wrong firmware, simply retry with the correct version.

  1. Download the latest firmware file from the Official Directoryarrow-up-right.

  2. Uncompress the ZIP file to a local folder. Do not run the updater directly inside the ZIP file.

  3. Run the EXE file as Administrator.

  4. If the message "Device is Detected" appears, click the Update button.

If the device is not detected:

  • Try a different USB port or cable.

  • Manual Recovery Mode: Hold [9] + [Enter] while connecting the IODD to your PC. Release the buttons once connected and run the updater again.

Finalizing the Update: Once the transfer is complete, click Exit. Reconnect the IODD and wait for 2–3 minutes for the internal processing to finish.

Do NOT disconnect the IODD while the LCD is blinking. This indicates the internal firmware is being written to flash memory. Interrupting this can leave the device unable to boot normally and may require a recovery/force-update procedure.
