15. Flash new firmware

The following steps describe how a new firmware image file can be flashed on a device.

Flashing a new image

It is strongly recommended to use a LAN connection when flashing new firmware. As the firewall configuration might change during the flashing process, and a wireless connection might be lost.


New device firmware can be flashed under System -> Backup / Flash Firmware by pressing the Flash image button.

man flash

This will open up a prompt for uploading the new image file.  After the image file has been uploaded, a new window will show the checksum and file size listed. It is recommended that the checksum and file size be compared with the original file to ensure data integrity.

man force

If the previous settings should be retained, check the Keep settings and retain the current configuration box. 

Only keep settings if configuration needs to be retained

Checking the Keep settings and retain the current configuration check-box will retain the current settings (Firewall, OPC UA, VXLAN, MQTT, etc...). If a clean install is desired this check-box should not be checked.

Next, check the Force upgrade checkbox to override the previous flashed image and click the Continue button to finalize the process.
