I have an O3DS, running firmware 9.9.0-26U. I want to downgrade it to 9.2 and be able to install CIAs onto it. So far, I think I understand how to downgrade it with the instructions at https://gbatemp.net/threads/simple-guide-to-downgrading-your-3ds.407888/ but I don't have Homebrew Launcher. How do I get this installed on my O3DS? What else do I need to do to downgrade and install CIAs? I'm terribly confused by all the different methods and tutorials on the forum - everything has changed a lot since the flashcard only days. Thanks.
