I've set up a few 3ds's with rxtools and emunand updated to the latest firmware the last few days. They all work great, can play the latest games flawlessly. I've just been leaving the system nand untouched on whatever firmware it already had (4.5,5.1,ect) since its only used for launching the ds profile exploit. am I missing something? I always see people mention "well 9.2 sysnand is still fully exploitable so should update to that". whats the benefit of the sysnand being on 9.2 over 4.5 when its not used for anything other than launching emunand?
