So now with all the hopes of CFW on my 3Ds without spending 60+€ on a flashcart I was looking for info and requirements where to only have the 3DS to downgrade and a DS flashcart to install the exploit. Well I'm a unlucky owner of a Ak2i, which the last working is 4.3... so even if I downgrade I cant use my flashcart to install the exploit. But then I started thinking in a different way to load the exploit, what if I send it over download play, I have a DSi so I could use that? I remember seeing this thread awhile back https://gbatemp.net/threads/ds-download-play-send-nds-file-with-planet-puzzle-league.306625/ and it is a great idea, but there's a catch, no homebrew is possible to be loaded on the client DS (in this case 3DS) unless it has flashme (there's no flashme for the 3DS). If it was possible to fakesign or inject or code to a ninty signed .nds and then place it on that game, there was a way to load the exploit without a flashcart (yes without!, I think that there's also a way to send demos using a PC) So any opinions, or this is completely impossible unless someone guesses the key.
