I hate the way they word that crap too..we can brick your hardware if you use any software that we dont like. This ok with you? Well if not you wont be able to play new games...
Screw you nintendo. Made me want to throw my damn 3ds out the window. Make some games that are worth buying...
although i ended up accidentally changing my nand with no way of going back bc i didn't know you needed a gamecube controller to restore it (i have a wii minus/1.1, which doesn't have gamecube controller support)
and if i find the sd card i have my NAND backed up on, i can not only restore the NAND if i solder the right part in, but i can also put my NAND on dolphin, then i can play dolphin online, like PMEX Remix or MKWii Riibalanced
