I recently re-imaged my S4016 firewall with 3.2.0 and tried to load the config, this then prompted me saying I don't have X amount of patches installed yet. It's requesting patches that I can't install because they are now "obsolete" . I noticed their is a force command to install in when SSH'd to the device. Will this work? or will I have to re-image again just to get back to 3.1.0P01?
Versions 3.2.0 and 3.1.0P01 are not real versions of the firewall software. Did you mean 8.2.0 and 8.1.0P01? Can you paste the text you get when you try to restore this configuration?
I see you posted this question on /r/networking also. Since you gave the correct versions there I can tell you what to do here.
You have a configuration file at version 8.3.0 with some patches on it.
