Thanks for having a go at dumping the firmware and sharing it with us.
I had a look at the dump with a hex editor, and unfortunately it contains just random data instead of the expected data which should be inside of a LiteOn firmware ...
I think this might be the same as Dell's PLDS DVDRWBD DS-6E2SH , here is a post with DiscInfo, A dump of the firmware(so you can compare the randomness if you would like) and a link to dell's firmware for the drive.
Here is a snippet from : viewtopic.php?f=12&t=49633&p=235520&hilit=6E2SH#p235520
, he also mentions another thread that might contain additional info.
There has been a thread ( viewtopic.php?f=32&t=47930
) about this Drive, but it was not explicitly stated as a request, and so nothing happend.
Here is a Firmware Dump, I made with C0deKing's Flash Utility for LiteOn 6.0.1:https://www.dropbox.com/s/6p3nargwr1x6u ... -6E2SH.bin
Here is the Link to Dell's Driver Download:ftp://ftp.dell.com/FOLDER23285M/1/SE2_CD11.zip
