Xbox 360 modders have discovered a new way to run homebrew apps and games on the console without needing to open it up. The new software-only exploit, known as BadUpdate, uses a USB key to bypass Microsoft’s Hypervisor protections and allows players to run unsigned code and games. Modern Vintage Gamer tested the exploit and found that it doesn’t require opening the console, but instead requires patience and time.
To use BadUpdate, users need a USB key, the exploit code, and a trial version of Rock Band Blitz to help enable the bypass. However, there are limitations: every executable needs to be manually patched, and the exploit isn’t always reliable or takes some time to pull off. The exploit also requires running every time the console boots up.
A step-by-step guide is available on YouTube and GitHub, allowing users to try the hack. While this exploit offers convenience, it also presents risks. Modders must proceed with caution when attempting to use BadUpdate.
