I'm running an Old 3DS on 10.3.0-28U and I messed things up big time. I went over to the usual homebrew site and got the ropbin for 10.3.0-28U BUUUUT I didn't know where to put it or how to install it. Because I'm a noob. Anyway, I updated my system, and now can't get back into the launcher via 2.5 ironhax to even remotely fix this. Are there any other ways to get back in? And if so, how do I install that stupid ropbin?
