I was thinking on updating my 2DS, to get some context from Nintendo eShop, but if i do that, my Flashcart won't work anymore, so i want to know if there was a legit way to factory-reset the console, perhaps format system memory ( i don't care what happens with the Miis or the faces ), because i don't have (not even a way to) a backup firmware ( no gateway, no link, no nothing), so, is there a way to Factory-Reset my 2DS back to 6.0.0-11/12 in a legit way? Thanks, Peace!
