You are right afterall.
I couldn't flash 3.0.0.4.378.7177 to my N56U in recovery mode.
Gotta roll back to 6117.
Also upgrading via the browser also doesn't work.
Weird.
I just flashed my router with this firmware. Everything seems so far so good at all, but there is always a constant problem with these recent firmwares. My xbox 360 always cannot to my 5Ghz wifi and says my password is wrong. However, it connects well to my 2.4Ghz wifi.
I wish they could...
