connect the phone to your pc, it is of MOST importance, that the phone is recognized as an ADB-device in your device manager
If it is not, the adb-drivers are missing. There are TWO possibilities to get those drivers:
1. Download PdaNet, install it and hope that the drivers are included for your system. Or:
2. Try these drivers.
Once your phone is recognized as an ADB-Device, you are ready to go.
Download Super One Click V2.2 and run it
Leave all the default settings and click on “Root”

Sure, why not
