UH12NS30 firmware 1.03 or later?

I have an old LG UH12NS30 in one machine, which is rip-locked.
I would like to use Mediacodespeededit to unlock it.

However, I noticed that my drive is currently at firmware 1.03 . The latest update from LG for this drive is 1.02 . Is there a way to extract the current firmware from my drive ?
I would like to try to avoid regressing firmware version while doing the speed lock.

Alternately, I’m also open to considering newer firmware for another LG drive if it is compatible with my drive.
