select modem USB diag
plug in phone, let it install drivers
reboot
connect phone, and launch the qpst config tool
go to ports
add new port ( you should see a device port listed)
goto active phone
then connect to your device
click start clients
go to software download (BE VERY CAREFUL!!! don't mess with software download, restore, factory)
