Nintendo's latest Switch 2 system update, version 23.5.0, has reportedly shut down ns2jb, the console's first software-only jailbreak. Dataminer OatmealDome confirms the OS exploit the jailbreak relied on is now patched, preventing game dumping and modding. The only potential exception involves some upcoming cartridge games and updates.
While exploits within individual titles like SmileBASIC 4 and Civilization VII remain functional, users can no longer break out of those apps into the broader system. Consequently, homebrew is limited to existing capabilities. Nintendo's official patch notes cover accessibility options, eShop gifting for family groups, and a new text-to-speech language, deliberately omitting the jailbreak fix.
This marks the first Switch 2 firmware since 23.0.1, the version originally targeted by security researcher Sammy "pepsipu" Hajhamid when he released the exploit on October 22. That exploit leveraged an integer overflow bug in SmileBASIC 4, a Switch 1 programming app running on Switch 2 via backward compatibility. Nintendo removed the app from the eShop shortly after release.
Despite the patch, exploits allowed early Switch 2 exclusives to boot on iPhone and PC, and the Zelda: Ocarina of Time remake received a native PC port. For now, users wishing to retain ns2jb functionality must remain on firmware 23.0.1.
