Nintendo update closes vulnerability used in Switch 2 jailbreak
The existing jailbreak remains usable on consoles that have not installed firmware 23.5.0, while some game-level entry points reportedly remain.
Nintendo’s system update 23.5.0 has closed an operating system security flaw used by a Switch 2 jailbreak, according to dataminer OatmealDome. The change reportedly blocks users from moving beyond a game’s restricted environment, limiting support for custom software and modifications.
Developer Sammy "pepsipu" Hajhamid presented the software-only jailbreak in October. It enabled custom programs, save-file backups and game modifications. The existing method remains usable on consoles where the new firmware has not been installed.
Entry points involving SmileBASIC 4 and Civilization VII reportedly still exist, but they no longer provide the same access under firmware 23.5.0. OatmealDome said the update again largely blocks the copying and modification of data belonging to newer games.
Some possibilities may remain: OatmealDome suggested that certain forthcoming physical releases, and possibly individual game updates, could still allow game data to be extracted. Previously copied data also remains available, as the firmware change cannot remove it retroactively. It is unclear whether or when a replacement for the patched exploit will emerge.
