Is the Desktop where the firmware file is? Did you also enable TFTP for Windows as per the link at the bottom of the guide? Did you wait to press enter on command prompt until step 11 was complete?

yes i have enabled tftp and desktop files also when power off the router for 10 sec then press the reset with paper clip my router only does 10 flashes and then i press enter at this point it has a orange solid light

Try downgrading the firmware and then factory reset, if it works then wait for the next update and see if it is better. If it doesn't help then I would recommend you contact the retailer you purchased from/make a ticket with Netgear and request a replacement http://support.netgear.com/
