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