How to get a successful downgrade on the 3DS

Format it before downgrading. Looks like that got me back to 9.2 without it getting an error.

Can’t put this in two categories, so I put it in the 3DS category.

How will I play Code Name S.T.E.A.M? It needs newer firmware.

NASA doesn’t work. Nothing gets installed. Thought it said you can install anything with version 9.2.

Probably need rxTools to see it. I’ll try one last time.
