So I followed this guide to downgrade from 11.0.0 to 2.1 in order to follow this guide and install FBI I couldn't get rxTools to work on 2.1, so I guess I have to be on 9.2. How do I update from 2.1 to 9.2? I've heard that 2.1 is unstable on N3DS, so I'm not gonna risk anything. Also my homebrew launcher doesn't work on 2.1. Thanks for the help.
