Assuming it's a European 3DS, the game "Cooking Mama: Bon Appetit!" has the 9.2.0-0 update directly on it, but you'd need a way to run homebrew after that, like Cubic Ninja since you'd have no internet browser. It might be easier to get a game like Luigi's Mansion 2 which would update you to 4.5.0-0E, and from there you could temporarily use the MSET hack to get going.
