I just bought a 3ds recently and I immediately updated it to v2.1 . I tried the updating technique where you wait 3 minutes for the v2.0 and deleting dstwoupdateb.dat but it didn't work. I tried using my original silver ds to update it but when I put the dstwoupdate.dat it says wait 3 minutes and my screen turns white and when I wait 3 minutes and try using it on my 3ds, it doesn't work. Any ideas please?!
