Hold down the 'Volume down' key (The Bottom Rocker Button On the Left Side Of your phone) And the Camera Button And Press the Power on button. Your Phone Should Start up Into a Weird Screen With
DEMSBL BOOT Loader for MSXXXXXXX

Flash the bootfiles first Then Flash The Firmware Files.
That Will Solve Your Problem.

Connect Powered on Phone to Cable.
Remove Drivers Of Unknow USB And Install Drivers. You Can Find Drivers on NsPro folder.
