What is the newest firmware for 4081B lg burner?

I have a 2 year old burner that is giving me some problems lately- it is an LG 4081B DVD burner. I want to upgrade the firmware, but all the old links do not work. Someone said the firmware was 104A - but I already have that - is there something newer? Does someone have access to the new firmware for this? I tried the LG site but can’t seem to locate this drive…Thanks

I doubt your drive is retail LG.
Surely OEM, but which one?
