I downloaded the firmware off this:

Is this the most recent firmware? And how do I install it?
Edit:
(Okay disregard the installation part, just did it.)
I'm a total noob. Do flashcarts work for the 3DS?
I have an M3 Simply flashcart with R4 Wood firmware on it. What would happen exactly if I use it with my 3DS? Few people keep telling me stuff like "It'll brick it" or something.
