I'm installing A9HL on a a new 3ds XL and I'm following this guide. On Section II it says to go to the website that is supposed to load arm11.bin but nothing happens. It also say I should be on 2.1.0 (I'm on 9.6). Assuming that's correct, I'm trying to downgrade by doing a ctrtransfer but Decrypt9 won't launch. It's showing up in the homebrew launcher but when I select it the screen does some funky stuff and it goes back to the homebrew launcher.
