Homebrew How to use SysUpdater on O3DSXL 11.8 ?

[TSP184]

I want to mod SSB4, so I read some guides to mod it (https://aminoapps.com/c/smash/page/...-modding-guide/l6fG_IDEd1orM3D452wnPk8a78QD1N, for example), and when I went in github to downoad SaltySD, it was only for 11.7 firmware. When I searched ways to downgrade my 3ds to 11.7, and used the SysUpdater way, but, while reading the "README" in 7zip, they warned the user to not run it in sysNAND Gateway mode, but I don't even know how to prevent it.

Can someone please help me with this problem ?

Don't downgrade, it's not even possible anymore. Use ModMoon instead.

Thanks, but what's that ?
