So recently I pirated a 3ds with the system transfer thing, however I do want to keep my NNID on my source 3ds but i already restored nand, so if I wanna transfer back from the 3DS I just pirated, do I need to format the source 3ds? (the one without NNID), and If I do; do I just lose all my NAND info? (A.K.A. Boot9, and the ability to download games)
