I am not sure if it is new findings. I read from a local magazine that an online firmware update tool for LG drives can be downloaded from:
which supports writers from 4081B to the latest 5163D.
I did get it and tried it. All way through the installation and execution, the program messages were in English. It showed that my 4082B was supported. But then to a point of online checking, it returned a message in words that I couldn’t read, which I guess were in Korean. I am not sure if it was telling me that there was no new firmware available yet (since A208 already installed) or something else.
Anyway, it will be a useful piece of tool for us the LG drive owners if it works as stated.
