Since I recently installed a9lh+luma on my old 3ds, I'd like to do a system transfer to my n3ds so I can hack that. The n3ds is on f.w. 11.0 so I would have to do the system transfer method to downgrade. Is there any preparations I should do as far as saves, nnid, and games go? I do have several downloaded games on the target 3ds and would like to not lose the saves+games. I also forgot to ask if Legends of Exidia is still a possible exploit. Also I would like to know if I could just insert an empty nnidsave.bin and that would clear the current nnid on my hacked system.
