I just bought a 4.5 3ds xl and GW device. I have been watching and reading guides about the device, and I have a question about emunand. When I format the emunand in the gateway menu, the meunand is at fw 4.5, how do i update it to 7.1? I know I can't use 7.2 yet, but from what I understand 7.1 still works for shop and online, etc. Is there a way to install 7.1 from a 3ds rom? Does any one have any sugestions?
