It's recommend that the devices running the latest firmware should not be downgraded to an earlier firmware version.
The new firmware is compatible with old configuration parameters, but not vice versa.

Log in the system via the web user interface, then go to
Settings > Upgrade > Upgrade Firmware
and enter the firmware file.

Hope this will help.

Kind regards,
