Updating xbox without xbox live
Not quite as easy or convenient as the PS3 updates but at least it’s possible.
You'd just need to connect the system online, go through making a Silver account (free), start up the game and then download any current updates.
In order to get these firmware updates for your Xbox, you normally would download them from Xbox Live.
Like all game consoles, there are occasional updates to add new features such as social networking tools like Facebook, Twitter, etc or the ability to play different types of files.
Or do I not need Xbox Live and simply need an internet connection? Doom, You should be able to patch the game without having to have a Gold subscription for Xbox Live."That file was never designed to replace the day one update," Microsoft exec Albert Penello explained via Neo GAF.
