All Barracuda Networks products, all firmware versions, serial numbers 25000 and above.
Please contact Barracuda Networks Technical Support for assistance - do not re-image a Barracuda Networks product without first consulting a Barracuda Networks Technical Support Engineer.
If warranted or desired, you can re-image a Barracuda Networks product (available on Barracuda Networks products with serial numbers at or above 25000). This will restore factory settings, including firmware version, and completely wipe out any configuration settings, logs, and other information present on the Barracuda. After a re-image, the Barracuda Networks product will be as it was when you first received it - with the default configuration, empty logs, and (likely) outdated firmware. If you wish to keep your settings, take a backup of your configuration beforehand, and restore it after the firmware has been update again. For help restoring a backup file, see Solution #00001924.
To perform a full system re-image, you will need local access to your Barracuda Networks product. Follow these steps to completely erase and reset your Barracuda:
