Where can i get the Xbox 360 firmware update if I don have Xbox Live?
The easiest way to download firmware / auto updates is to temporarily relocate your 360 next to the router / PC or a friend’s house. You don’t need gold, just plug and play. I do this for my nieces, they bring over their games and I quickly load them up one by one in search of firmware and software updates. There’s even a lot of DLC that can be played offline such as Borderlands and Marvel Alliance. Seriously, if you have the PC to create a CD or USB save, you may as well skip that timely step and plug in direct.
