Hi. I got one of the first EZ-Flash Redux flashcard for free, I have to test it for a website. It's ok, I know how to use it, I have A9LH and the Payload to launch the "Launcher.dat" on the root of my n3DS. It's working on my 2DS, but on my n3DS I just got a Black Screen after the intro screen. What is the difference between the A9LH on 2DS and n3DS ? Can I swap it to test ? Thanks! EDIT: Taken the old LUMA a9lh to my n3DS but the flashcart doesn't work either.
