Ok so I have an O3DS XL and it's on 10.2 I want to downgrade it to 9.2 I read how to do it and it seems simple enough, I have a Sky3ds (Blue Button) but now that it can't run new games with AP its pretty useless to me now. I heard however, that you can install .CIA files if you use CFW but what CFW do you recommend? Also what is FBI Injection?
