I need to SBF back to stock after messing up while trying to install a ROM. I had a bootstrap recovery file, but now I can't access it. I've decided to just SBF back to stock. I downloaded RSD Lite and the full SBF file. However, RSD Lite does not recognize my phone. I have already installed the drivers, but it still doesn't recognize it. I can't get the phone to boot either, it just hangs at the M logo. When I plug it in to the computer though, I can get to the bootloader screen, and it says OK to Program. So, am I totally screwed? Or is there a way I can SBF back?
