Alright, so everything went really smooth. GodMode9 is installed. Luma3DS V8.0 is installed. FBI and LumaUpdater are all installed but the problem is hat I have pretty much lost all of my previous data, although it is still on the SD card (the data was not important at all, there wasn't much either) but now my Homebrew launcher isn't working from the sounds app, it says "Cannot play file". So now that I have installed CFW, I just wanted to ask that is there a need for Homebrew now and how can I install one, just like I did before? Thank you.
EDIT: I figured it out. Installed Homebrew launcher through FBI. Thanks.
