I am haven a issue with the wotanclient i have baught a credit to unbrand my att w580i.

and i read the guide but hit a unknown snag

so i preped the phone by taken out the sim and memory card and battery. like the guide told me.

ran wotanclient pressed start and asked me to plug in my phone via usb.

put back in the battery pluged in the usb, held down the "C" button {nothen}

(side note)
when pluging in the Se w580i window's wizard driver pops up looken for drivers for the unknown device. is this the issue? if so how do i fix it and if i fix it could i continue with my unbranding?
