@Raven Queen Nintendo released a new update for the 3DS a day or two ago that breaks all current softmod methods. If your system has already been modded, you're fine but if you haven't yet, you'd need to use a flashcart that has ntrboot on it (or can be flashed with ntrboot), another already hacked 3DS, or physical hardware modding to your system in order to mod it
Oh, I've done some research and since I already own a hacked 3DS and a physical copy of Sticker Star, I can hack another 3ds with stickerhax
Otherwise yeah easiest way would be to order a flashcart
