You need CFW. And you can't downgrade from 11.0 without another already hacked 3ds. And you'd need a NEW 3ds anyways. o3ds doesn't work.i have old 3ds 11.0.0.33u firmware . how can i use this cheat? if i need new 3ds with lower fitm which do you recommend? and which Cfirmware guide should i use thanks
