So yesterday I was uploading a few new games into my sd card to install them through fbi, but one of the CIAs messed up my sd card and i had to reformat it. This of course deleted everything in the sd card. Now the question is, do I have to reinstall Homebrew? This has happened to me before, and there was a suggestion to follow 3ds hacks guide from a certain step, but I cannot remember where I had posted the question. So what should I do?
