I just got a 3DS with firmware 4.5. As far as I know, for the past few weeks up until 2.4 was released I would not be able to format my emuNAND because I couldn't download firmware 8.1 and Gateway didn't have the latest FW working yet. I assume on 2.4 I can format my emuNAND and update from the internet?
However I'm having a problem. After installing the blue card exploit I tried using firmware 2.3b. On 2.3b I am unable to boot into gateway mode and the diagnostic fails for all tests. I tried using the 2.1 and 2.2 launchers and they both recognize the card and allow me to play roms. I have tried with the 2.4 launcher.dat and I get the same error of "card not recognized." I read that I might need to update the card itself by holding L and R while I boot into the Gateway menu. When I tried this it prompts me to update the card but I'm not sure whether this would break anything. I'm just trying to be cautious, could anyone tell me if this would be safe to do? Thank you.
