So I'm about to downgrade my n3DS XL to 2.1.0, but there's something I wanna make sure is still there once it's done. Will the microSD FTP server option still be available once I've downgraded? I don't have a screwdriver atm to access the microSD so I've been using the FTP server, but 2.1.0 is only meant for o3DS so I thought it could remove the option.
