I think it works like this, on my first try before 11.1 it took over 40+ installs. But 2nd time, it did around the same thing, until i noticed after it corrupted, and it forces you to choose a new mii. When i went to install like past 40+time the 2nd time, i left the game corrupted, did not choose a mii, when i installed for a final time, it worked. i think if you left it corrupted and reinstalling, it will work.I see, then I guess you need to still trying since the installer is a little bit unstable.
Also a minor problem.
When i boot my homebrew menu, with steelhax, it just goes to the root of the sd card, I had to select boot.3dsx to go to the actual homebrewmenu, anyone have this issue?
