You have officially simplified and distilled what I'm sure is actually a very complex process into something so simple a child could do it without bricking their console. You have my deepest thanks and applause for all of your hard work! Just finished successfully downgrading one new and one old 3ds for myself (admittedly the old one was just a guinea pig, in case of failure) so I can FINALLY get around to playing Neo X! I literally have over 200 hours into my copy of X, but I was wanting the challenge of Neo X and thanks to all of your hard work I finally can!
And for those curious, my favorite Pokemon for online battles is ALWAYS the shiny Imposter Ditto I spent around 20 hours hunting through friend safaris for. Throw a choice scarf on him, and he can devastate anyone if used properly (your opponent thinks they're setting up their own sweeper, but really they're setting up YOURS).
