A very noob-like question I’m about to ask so sorry, but I just wanna be extra safe. Does putting your 3DS in sleep mode while on CFW no matter what app you’re in (a normal game, application, Homebrew app, FBI) do anything to your 3DS and are you at the risk of something bad, such as a ban? I know, a stupid question but I’ve always wondered this since being on CFW.
Quick tip: If you do anything that a non-CFW user can't do, it could have consequences. Just follow those lines without sacrifincing what you want (e.g. custom themes, free games...) and both your console and you will probably be ok.
