Hi all, really need some help from more experienced people than myself. I put CFW onto my 3ds years ago, i recently started playting with it again and have updated Luma and the Luma updater to their latest versions, the trouble is i have no idea whats actually on this thing, it talks about a9lh and boot9strap? is there anyway to just delete the files off the SD and start from scratch with a clean install so i can actually keep a record of whats on it etc? i dont mind losing games or any save data. Im sorry if this has been asked and answered but i cant seem to find a guide that answers this. Basically i'd like to just start over again because the SD card is a mess and i cant tell whats running on it, thanks
