Acer 48xCDRW/16xDVD Need Firmware

I flashed my Acer 48x24x48/16xDVD drive (Liteon OEM) with the latest KH0P firmware without backing up the old firmware! I have looked all over The Firmware Page and found nothing. I am going to return the drive to the store, does anyone has this drive give me a hand?

Thanks in advance!

Yeah, I got your email and replied.
