Hmm, not trying to judge, or anything, but why choose the dishonest path about solving this situation? Why not just handle it like a man, sell your updated 3DS, and buy another one with lower firmware? I don't think it's right to destroy a perfectly good product, just to dishonestly save a few bucks. If money is really an issue for you, OP, have the person who accidentally updated your 3DS to pay up the difference.
