I think I found a new exploit guys.. it's free, if you do it wisely. I call it.. RefundHax.
Return or Sell and 3DS for a new one that's on FW 10.5 or lower. This would allow you to use MenuHax and BrowserHax.
So RefundHax --> 10.5 --> BrowserHax/MenuHax.
If you aren't able to do RefundHax, then NinjHax and OOTHax are your only options.
