I want to be able to re-scan the QR code after I downgrade the firmware so I can go back to homebrew channel. I accidentally installed the Ninjahax the first time. Now it never asks to scan. When I select QR code it goes right to homebrew channel. But only on 10.3.0-28u (the firmware it was on when I originally installed it). I've tried pressing the key combo mentioned in the title at the main CubeNinja screen but nothing happens. No matter what firmware I'm on. I want to do this because after downgrading to 9.2.0-20u I still couldn't get my gateway to work. At that point I couldn't get into homebrew channel for troubleshooting so I had to update back to 10.3.0-28u. I'm going to try and downgrade from 10.2.0-28u to 4.5 and see if I can then do a normal upgrade to 9.2 (if I can find a cartridge that has that upgrade).
