I've done the downgrade of my old 3ds xl to 4.2 to use rxtools 2.6. But my rental games were having it's save data corrupted.
Then i decided to formart 3ds and start again from scratch to downgrade 3ds but now to 9.2 and install rxtools.
I've already installed menuhax and now i was attempting to access sysupdater to begin the downgrade, but when i click on sysupdater into the menuhax, all i got is a black screen. I don't know why but i wonder if it's the fact sysnand and emunand are separated. I'm lost.
