I am planning on installing luma on my 3ds. I have four questions... First, when I install should I disconnect from the internet until Homebrew is fully installed? Second, Does the freeshop work offline and if not should I insert it into an application like face raiders? Also is there anything else I should do in advance or after installing Homebrew to make sure I don't get banned? Finally, should I make a NNID? Thx in advance!
