Hi, I purchased a used "New" 3DS (Non-XL the Black Friday Mario Edition) and it came with Luma3DS installed on it from the previous owner. I have no clue how to use this and would like to just get rid of it but cant find anything on how to for my particular situation. I don't have a system backup file, I'm currently running Version 11.3.0-36U, it looks like it was formatted through the 3ds menu before it was shipped out. and there is something called FBI installed on the home screen even after formatting it again. Also can I log into my Nintendo Network ID without risking getting banned or something? The seller did not mention this at all in the description and I'm really feeling annoyed right now.
