AI Agent Assists Switch 2 Jailbreak as Developer Reports Two Weeks of Trial and Error
The jailbreak did not come from autonomous AI discovery; the developer's account describes two weeks of trial and error in which the model searched WebKit and Petit Com 4 before a file-management vulnerability provided the needed access.
Reporting from 1 source: GIGAZINE.
A jailbreak method called ns2jb for the Nintendo Switch 2 has been released, developed with the help of OpenAI Codex, OpenAI's coding AI, according to the developer Sammy Hajhamid. The tool works through software alone and supports system version 23.0.1. Hajhamid connected JetKVM devices to the original Switch and the Switch 2 so OpenAI Codex could see the screen and send controller input, and used a SwitchBot to press the power button after crashes.
The setup matters more than the result. Hajhamid attached a JetKVM to each console, an open-source device that captures HDMI video and sends USB input, so OpenAI Codex could read the screen and act on it. A SwitchBot positioned over the power button let the AI restart the Switch 2 when an experiment crashed. With those in place, the AI worked through WebKit first, where a known vulnerability gave some control but not the privileges the jailbreak needed. The search moved to Petit Com 4, the BASIC programming software for the original Switch that also runs on the Switch 2, where a flaw in numerical calculation allowed access to memory outside the intended range. That access stayed inside Petit Com 4 until Hajhamid identified a weakness in fs, the system handling file management, and used it to get past the check that verifies whether a program is legitimate. The released ns2jb supports version 23.0.1 and is described as enabling game modding, save data backups, and unofficial software.
