AC313u firmware won't update

[ChrisN812]

I have a AT&T branded AC313u which i believe has corrupt firmware and am trying to flash updated code which fails to install.

I see the device in the device manager as 'Sierra Wireless CNS Port (COM19)' 

Trying to fflash the latest code from the site: AC313U_BZ42729_03.05.10.02_Configure_v3

Can someone please help?

OS Windows 7

Hello ChrisN812

If the firmware corrupted you may need to contact AT&T to see if they can help with the AC313u as they so the support for this device.
