Switch 2 jailbreak: beware of fake tools on GitHub

A fake "CFW activator" for the Switch 2 is climbing on GitHub. Yet no custom firmware exists: here is how to spot these traps.


A repository that ticks every box

Since the release of ns2jb, searches for "Switch 2 jailbreak" have exploded, and scams follow. A typical example: a repository called switch2-bootstrapper, opened on October 26, 2026, which already has more than 120 stars on GitHub but no forks at all: the sign of bought stars, not of a community. We deliberately do not link to it.

It presents itself as "the official" USB-C utility for activating custom firmware. Yet:

• the repository contains no code: only a README, a licence and an empty file;
• it asks you to copy a PowerShell command that downloads a script hosted elsewhere, "because GitHub's scanners block scripts";
• it calls antivirus alerts "false positives" in advance and claims to be "100% safe";
• it promises to "bypass signature checks" on every firmware, with an automatic NAND backup;
• it ends with a list of keywords for search engines.

A PowerShell command from a stranger means handing them the keys to your PC: stolen accounts, passwords or wallets, ransomware. We did not run this script, but every classic sign of a malware trap is there.


What really exists

• There is no CFW for the Switch 2, and no "one-click" tool.
• The only public jailbreak is ns2jb, by pepsipu, published on GitLab (not on GitHub) on October 21. It requires firmware 23.0.1, the game SmileBASIC 4 and a computer connected to the console, stays in userland and disappears on every reboot. How it works is detailed in our explanation of the exploit.
• Reworked copies of ns2jb are also going around: always prefer the original repository.

Good habits

Be wary of any repository without code, any command to paste into a terminal, password-protected archives and requests to turn off your antivirus. When in doubt, ask in the Switch & Wii U Questions/Help section before running anything.
