I got it working for xbox 360, holy shit took me like 2 hours. Ok so first delete the cache on your hard drive then restart your xbox. Go to the online mode straight from the loading screen, once you've created a character, join a game lobby that someone is currently playing in and you'll be able to join it and play free mode or something. If no one on their friends list got gta 5 working online then they can add me my gt is XeXBoolean
