Stuck in v2.02 BL, USB on PC not recognizing...

[JDM_SOHC]

Ok so im downgrading my friends wm6 rom on his apache to the stock rom, and of course it crashed about 20 seconds into the downgrade on the BL screen... so i try hard rest, soft reset, MTTY, Exit Bootloader Tool, ect and for some reason my vista computer won't recognize his phone at all, but when I plug in my mogul it recognizes it right away... I put the "nk" file on a formatted memory card and reset his phone to try flashing via SD card, and still nothing... what step did i miss..?? in MTTY also, USB is not an option to be checked..??
