Ah that's a shame. If you do get access to a friens's one or a public one or something then do let me know. I'm impressed that you did it by hex though. It's a lot of work. What kinds of things did you change?
Smash stack is the exploit to get the homebrew channel right? I think that's what I used to get nintendon't on my wii u. Correct me if I'm wrong.
