Hi, I don't know if people are still posting answers or solutions, but I'll try anyway. About three days ago, I installed this version on my Xbox 360, which was running version 17489, because I wanted to install the Bad Update exploit on my console. After installing the update, everything went well except the console stopped producing any audio at all. There's no audio in games, in the main menu, nowhere. I don't know if anyone can help me. My console is an Xbox 360 Slim. I've tried everything: I've checked the settings, changed the cable, and even checked if the TV was having sound issues, but nothing has solved the problem. If anyone can help, I would greatly appreciate it.
