Hello. I have my dad's Bricked Vibrant here. I have been searching all over for this problem but I could not find it so I am asking here.

When I turn the phone on, it goes to the download mode where if turn off your phone while in download mode and it shows a phone and a PC whether the phone is connected to a usb or not. I was trying to do an odin but the phone will not connect to the PC. Any ideas? any help is very appreciated!
