Need help with M3 New Firmware

So I downloaded the new firmware for the M3 DS Real...but, what do I do next?
I just put the folder in my micro sd?

Sorry, I really am new at these kind of things x)

 

you take the "system" folder and place it on the root of your sd card, just drag and drop, where your old "system" folder was, its simple as dragging and dropping in there, when it asks to replace old system folder with new, say yes.
and your done
enjoy

hope this helps

 

Omg thank you so much <3
