Just do this, Hold down the "volume down" button and the "windows start menu" button, while holding these 2 down hit the power button up top. The phone will go to a multi colored page that says serial at the bottom
Now plug in your USB cable and it will switch to USB from serial. You can at this point flash a good ROM, whether it be stock or something else.
Ive thought I have bricked my phone many times but this always works to get a good ROM back on it and was kinda hard to find the button combination that worked (actually found it myself by accident).
Good luck
