GoKawiilResearcher releases software-only jailbreak for Nintendo Switch 2 firmware 23.0.1
A developer has published ns2jb, a tethered, software-only jailbreak for the Nintendo Switch 2 running the latest 23.0.1 firmware, via a public repository. The exploit reportedly allows arbitrary native code execution as a system module, enabling homebrew apps, save file backups, reverse engineering of games, and hardware access via MMIO. The developer used AI coding assistant Codex to help build the exploit and to mod Mario Kart World as a demonstration.
GoKawiil's interpretation of the reporting above, not reported fact.
This appears to be the first public jailbreak for the Switch 2, which could open the console to homebrew development and game modding before Nintendo patches the exploit. The use of an AI coding tool to assist in both the exploit development and a working game mod suggests AI-assisted tools may increasingly speed up console security research, though the developer notes the jailbreak itself still required about two weeks of dedicated effort.
