Firepower Management Center from the Cisco Smart Software Manager. Choose System > Licenses > Smart
Licenses and click the deregister icon.

Obtaining the Restore ISO and Update Files
Cisco provides ISO images for restoring appliances to their original factory settings. Before you restore an
appliance, obtain the correct ISO image from the Support Site.
The ISO image you should use to restore an appliance depends on when Cisco introduced support for that
appliance model. Unless the ISO image was released with a minor version to accommodate a new appliance
model, ISO images are usually associated with major versions of the system software (for example, 5.2 or 5.3).
To avoid installing an incompatible version of the system, Cisco recommends that you always use the most recent
ISO image available for your appliance.
Firepower devices use an internal flash drive to boot the appliance so you can run the restore utility.
Cisco also recommends that you always run the latest version of the system software supported by your appliance.
After you restore an appliance to the latest supported major version, you should update its system software,
intrusion rules, and Vulnerability Database (VDB). For more information, see the release notes for the update you
want to apply, as well as the Firepower Management Center Configuration Guide.
For your convenience, you can install system software and intrusion rule updates as part of the restore process.
For example, you could restore a device to Version 6.0, and also update the device to Version 6.0.0.1 as part of
that process. Keep in mind that only Management Centers require rule updates.
To obtain the restore ISO and other update files:
1.
Using the user name and password for your support account, log into the Support Site
(https://sso.cisco.com/autho/forms/CDClogin.html).
2.
Browse to the software download section (https://software.cisco.com/download/navigator.html).
