Oh, I don't want to go into Nintendo's servers...I just want the 3DS to send them false information they'll believe as true...Like when Obiwan Kenobi told the stormtroopers that those weren't the droids they were looking for, I'd like for my 3ds to tell Nintendo's servers "this is the latest firmware, move along, nothing to see there"...disquising my 9.93DS as a 10.3 one...
That has already been done, but only for people who have kernel access. We may find a way to do this on 9.3+ but right now it seems unlikely.
