Oh man, that sucks. Well, unfortunately, that's the danger of flashing in Windows--a very hostile environment in terms of communicating with drives.
Normally, I would recommend a MtkFlash (there are ways to obtain unscrambled firmwares) recovery, but there's a problem here: your drive's unique calibration data is stored in the firmware itself. So I don't know if this would be a good course of action to take.
My recommendation is to contact LiteOn tech support, tell them that the drive misflashed, and they will most likely have you send the drive in for a replacement.
It also sounds like your drive was only half-flashed, so if you can't get a replacement, there may still be another way around this, since the calibration data is stored near the beginning of the firmware and not at the end... but I would recommend pursuing the replacement-for-misflash first.
