The thing is, we can block Nintendo server access with Tubehax DNS server, which makes me wonder, would we be able to redirect the 3ds via a DNS server to a custom server wich sends out "fake" new firmware, containing the old 9.2 one. Im not into hardware near coding nor networking and do not know if the updates are specialy decrypted. I mean, the concept is straight forward, so I wonder if its possible and if not, what is the thing preventing it.
