ASUS RT-N66U B1 stuck on firmware 3.0.0.4.220

Hi, there,

Just got ASUS RT-N66U B1, which has firmware 3.0.0.4.220 on it. Actually even the sticker on the box indicates firmware 3.0.0.4.220.

Tried updating the firmware and got this message although here I can find newer firmware versions: http://support.asus.com/Download.asp...-N66U+(VER.B1:


Downloaded both version 3.0.0.4.246 and version 3.0.0.4.260 of ASUS RT-N66U B1 firmwares (source: http://support.asus.com/Download.asp...T-N66U+(VER.B1)) and tried installing them manually and got this result:




Could someone please explain me why my router ASUS RT-N66U B1 is stuck on firmware 3.0.0.4.220 ? Maybe there's another way to "push" the newest firmware on it ?

I had no issues whatsoever with my previous asus router (RT-N56U) in respect of firmware updates through asus router utility.
