Interesting you should ask, if you are having problems with burning then try it, but here's my story. I just bought a new LG 32x burner about a month ago and upgraded the firmware, since then I haven't been able to burn a disc, and before the upgraded firmware I could. If it isn't broken don't fix it, in your case the firmware isn't really adding anything significant, so I would suggest you leave it as it is. I am happy I got my burner replaced since it was under warranty by the store, now I have a good burner again. I think the flash wasn't official either for me so that may have attributed to the drive's failure. Since your firmware is official you may be better off, but like I said, do you really need it?
