Use the ntrboot multi system method in 3ds.guide, it will guide you through it. The backup instructions are in there.Hi Jdbye thank you for the reply ! I do have another already hacked 3ds so I'll try to do the multiple system method, sorry for the newbie question but how exactly do I dump my own flashcart firmware and restore it later if it gets bricked ? Is there a program to this ? Or the ntrboothax installation process already has it ? And are they any video guides to do the multifamily ntrboothax method cause I only found the single console ntrboothax method. Thanks again Jdbye !
Don't use a video guide. Only use http://3ds.guide
Video guides get outdated almost instantly.
