8320B to 8401B!

I successfully upgraded my LG 8320B drive to 8401B using the
firmware available at the Korean LG site. I don’t know if
the 8401B firmware has any advantage over the 8400B one, but
I’m sure it’s as good or better. I’ve done an hex comparison
and there are some differences between the 8400 and the 8401
hex files, but they have the same size. The features are the
same, no Mt. Rainier support :frowning:
I think it can be less picky but I doubt it.

I’ve seen in a thread some users saying that the 8401B was
created only for the Korean market, because originally the
8400B had a 8MB buffer, and LG changed it to 2MB. And to avoid
confusion, the 8401B is the 2MB version. It could be true, but
I doubt cuz why they would release a 8481B version too?
The 8480B writer is somewhat new and I never heard about a 8MB
version, I don’t see any purpose to create the 8481B model.
I also heard that they created those models (8401B and 8481B)
because there are lots of complains about picky firmware.
But this theory is fragile and can be easily defeated, because
the differences between the 8400 and 8401 firmwares are minimal
so I don’t think the 8401B is less picky than the 8400B.

Do you know anyone else who said the same thing in that specific thread? It was me who mentioned it in CDRLabs and other English-language and Korean-language forums.

Why did you think that was a “theory” and defeat what? You can look into the largest South Korean web forums related to LG CD writers and read all the threads and news posts yourself if your Korean is better than mine. If not, you can either trust me or distrust me.

Just quote me directly if you want to use the information I gave on public forums without distorting what I said.
