About the security baseline: firmware with a higher security baseline can stop a device going back to older firmware. A device already on a higher baseline than V2.4 may refuse this file, and after installing it you may not be able to downgrade to firmware with a lower baseline.

Other files for much of the same hardware, from any vendor.
