Switch 2 software-only jailbreak reportedly discovered
A reported tethered exploit may run native code and homebrew on Switch 2, but it still depends on a delisted title and has not been confirmed by Nintendo.
Nintendo’s Switch 2 has reportedly been opened up by a software-only, tethered jailbreak that can run native code, although the claim remains independent research rather than an official Nintendo announcement.1
The exploit, called ns2jb, was reportedly created by security researcher and modder Sammy “pepsipu” Hajhamid with help from OpenAI’s Codex. According to the report, it works on Switch 2 firmware 23.0.1 and requires access to SmileBASIC 4, a programming title that Nintendo appears to have removed from the eShop.1
What the reported jailbreak can do
The creator says ns2jb can run homebrew, support reverse engineering and game modding, back up save files and access much of the Switch 2’s peripheral hardware through memory-mapped I/O. The claimed demonstration involved modifying Mario Kart World with extra characters, including Cinnamoroll, Peter Griffin and Hatsune Miku.1
Those are substantial claims, but they should be read as claims, not as a confirmed public jailbreak release. Nintendo has not announced that it recognises the exploit, and the available reporting does not establish whether the method is reliable, broadly usable or safe for ordinary players. The Verge and Notebookcheck were cited as additional reporting behind Nintendo Life’s coverage.1
The tethered nature of the method is the important limitation. If the console is switched off, the jailbreak reportedly has to be applied again, so it is not the persistent, one-time modification that many homebrew enthusiasts would hope for. Access to the now-delisted SmileBASIC 4 is another obvious barrier.1
Why SmileBASIC 4 matters
The reported route echoes the 3DS era, when SmileBASIC was also involved in homebrew research. Removing the Switch 2 version may reduce the immediate route for new users, but delisting a piece of software does not by itself prove that the underlying vulnerability has been closed. It may instead make legitimate access harder for owners who already bought the title.
For Nintendo, the next steps will likely involve deciding whether the exploit affects a narrow firmware configuration or exposes a broader weakness in the console’s software security. Until the researcher publishes reproducible details and Nintendo responds, the sensible conclusion is that Switch 2 homebrew has reached an intriguing early milestone — not that a dependable consumer jailbreak is now available.
Our opinion
This is interesting news for preservation and homebrew communities, but the caveats matter more than the headline. A tethered exploit dependent on a delisted title is fragile, and readers should not treat a report of native-code execution as an invitation to download unknown tools or modify a console they rely on. The story is worth watching; it is not yet a reason to call the Switch 2 fully jailbroken.
