Please visit the LG support site. There should be some info or contact adress.
If this is a DOS-flasher you have used, just try again or on another computer.
I visited the LG Support site but I find nothing.
I put other CD drive in my PC and works fine.
So I think the problem is in my LG CD drive when I load the new drive.
I cant realize the drive was wroken because there were a probem loadind the firmware.
