I checked your messages and looks like that you have tried to reflash, but you didnt give helpers any feedback except that it doesn't work. I would really much like to help you more, but I need information.

- What Os are you running and is it 32 or 64bit
- Do you have ANY nokia software installed on your computer?
- Do you have any other devices (exept mouse and keyboard) attached to your usb. Even usb hubs?

Please describe in detail that where it fails when you are trying to use CMD flash utility?
