11.0.0-33U 2ds. Entrypoint is soundhax. Black screen on safehax success (all released vers of safehax, I've been at this one a while...). Used both waithax (including the updated fork) and fasthax (inc zoogle's safehax+fasthax) entry methods several times.
Could the decrypt9wip.bin (arm9.bin)...
Dunno about you, but YSmenu didn't fix it for me. Maybe it updated and I'm not using most up to date one. ... And yep, there be an update for it. Oh well.
Try using the arm7.bin from another source if your wifi is messed up with the one you used.
(HINT: Someone said Bomberman 2, the arm7 from that game miiight just work if you try it. )
I feel like school, back when I was actually in school, was more entertaining though, because of how much I get to interact with people, hang out with friends, and other stuff like that. All I get to talk to at work is my boring coworkers lol
