Connect the phone via a USB cable and browse to the Web page of the phone by going to AFTER going to Start - - > Run - - > ncpa.cpl - - > Right click on the “Wireless phone network connection” - - -> Properties - - -> TCP/IP - - - > Use the following IP address - - -> Entered with a mask of - - -> Clicked on OK and then OK again. (The IP address of the computer should be any IP address in the 192.168.1.[1-254] range EXCEPT and any other IP address already being used in the network.)

3. Click on "phone upgrade" and entered admin/Cisco as the username/password. (note that the password has a capital "C")

4. Browse to the TAR file firmware version saved on the computer and upload the firmware on the phone.
