I think it blocks update notifications in emuNAND. sysNAND is another matter though.
Hm. I've had updates blocked in my router for so long that I must've forgotten how it worksGateway/emuNAND doesn't block update notifications.
Source: my emuNAND that gets update notifications.
If it's on sysNAND, you can enter Recovery Mode by holding down A+L+R+Up while turning on your console. If it's on emuNAND, you can't enter recovery mode (to my knowledge), so you'd just have to ignore it.Cool, so I guess my router is probably doing as it was told an blocking the 3DS from reaching Nintendo's update servers. Or I haven't left WiFi on for long enough to get one.
If I get an update nag screen, how do I get rid of it?
