you might want to do the second two for game updates, then move on to the first one to be completely offline. you can check the min firmware for the latest updates here:
https://ps4database.io/ you can download updates from that site as well, but they're not fake signed. if you're getting the game by other means <wink, wink> other than dumping the games with the app dumper, you might want to find the update fake signed as well, 'cause a legit update won't work with a fake signed game. I've dumped all of my games and only street fighter v has the latest update higher than 5.05. the update folder for it, at least on my system, contains two update pkgs, so updates may not overwrite each other. I'm not sure on that one. both updates are the same size though (over 9GBs apiece), so I don't really know.
