ns2jb

A jailbreak for the Nintendo Switch 2, dubbed ns2jb, is said to run on system firmware 23.0.1 and to start through a vulnerability in SmileBASIC 4. The exploit is reportedly still tethered, meaning the console must reconnect to a computer after reboot, but it could enable homemade software, mods and save-game backups. Nintendo has not commented, and the company has historically moved quickly to patch such holes.

A jailbreak for the Nintendo Switch 2, named "ns2jb", has been released. It is described as a software-only exploit, meaning it does not require hardware modifications, but it is tethered, so the exploit must be reapplied after every reboot. The release is being discussed in gaming and homebrew communities, where jailbreaks typically open the door to unofficial software and piracy concerns.
