T10D_wnos

Hi,

I was wondering if anyone can help me with this particular dilemma I'm currently having. I'm trying to install a new firmware update to my T10D, but the file the firmware has is T10D_wnos. the usb imaging tool does not recognize that type of file. 

I was wondering if anyone could tell me which software tool i can use to make this firmware available to use in a usb so I can push the update to my T10D.

any help is appreciated.
