XB36Hazard remains useful for older RGH 1.2 / 2.0 builds and for repairing KV / building custom updates. XB36Hazard Xbox 360 Tools 7.0.0.3 is a powerful but legacy tool (last updated ~2015). For modern RGH 3.0 installs or 4GB Corona/eMMC support, use J-Runner with Extras instead. However, for specific tasks like $$ystemUpdate creation or key injection, this tool is still unmatched in simplicity.
