I found this via Google.
Flash to boost - or repair - Page 2 - xda-developers
xda-developers - View Single Post - Qualcomm CDMA Technologies MSM Windows driver
it was in response to your missing driver.
i cant help with the process, i dont have this device and am not familiar with what is explained to do.
hope you understand it.
Are you using the original Samsung USB cable? If you aren't that could be part of the problem. Those drivers should be compatible with windows 7. Do you have another computer you can try out? Try switching USB ports on your computer. Make sure that when you connect your phone to your computer the phone isn't connecting as an installer. You want it to be on mass storage.
