NetBotz 5.4 firmware
Cause:
Prior versions of NetBotz 750/755 firmware allowed you to upgrade from any version to the most current. This is changed for 5.4. You will receive an error of "Firmware update failed because of invalid signature (40)" if attempting to upgrade from 5.3.4 or prior.
Resolution:
The NetBotz 5.4 update requires that the NetBotz appliance be at version 5.3.5 to work. If you're seeing the above error, make sure you update to 5.3.5 prior to upgrading to 5.4
Please check release notes for upgrade information as well as any future version requirements.
