I suffered a partial downgrade using freakyhax, which only works once and then you need to redo it, which I am not in the fucking mood to do, so yeah, does oot3dhax work on all of these? And how do I know which file to use? Yes I have powersaves :3. I got it early on when using my 3ds, I am super glad I got it. I bought my New 3DS a few days back, it arrived today, on v10.7, brand new!
