I'm not sure where you got your phone from but Intratech's thread here has all the carrier branded firmware you'll ever need and his official firmware thread is here. One of the two threads will have exactly what you're after.

Yes I know about this thread but all the firmwares in Intratech's threads are for ODIN and as I said in my post, I get no USB connectivity hence why I asked if someone had a link to CWM stock roms.
