When I first installed this unit in my 2010 MBP last year I did the firmware update to EXTOCB6Q. As I recall I had to download the the Samsung file, rename from .iso file to a .dmg file and burn the image on a cd-rom. The firmware updated with no issues. Now, I see firmware is available to go to the EXTODB6Q version. Is this update recommended? I assume it would be functionally the same process, download, rename to .dmg, burn, reboot from optical drive?
