So I'm rooted and have the Samsung drivers installed. I have flashed CM7, but am having major problems with it, so need to revert back to stock. Here's the problem...I need to use Odin, but for some reason my computer has stopped recognizing my phone when I plug it into USB. It says DEVICE NOT RECOGNIZED. I've tried uninstalling the Samsung USB drivers and reinstalling them. No dice. I'm kind of stuck now, since I when I boot into recovery, I see the normal options to wipe data, install zip, etc, but none of the buttons work to select an option. They just dim the screen and show the Rom Manager hat. Any suggestions? Am I totally screwed?
