Since there can be glitches "during" firmware updates, they don't like you to update unless its really necessary... Sometimes fixes can fix a given problem but create others that were ok before.
But generally, things get better.
I like to have the latest before I set all my settings as a firmware update will wipe everything usually "but not always".
Barring your usb loosing connection or power etc, you should be ok.
I just bought the LN52A650A1F and mine has firmware version 2002.2 dated 5/28/08... when I go to their website, all I see is 2001.3?
Apparently I'm running a version later than has been released to the general public... "maybe I'm a beta tester?... LOL!
Can you tell me if it's safe to update my firmware. The site says to not update it if you do not have the random shut off problem. I don't have the shut off problem, but I do believe that I have the stuck 120hz auto motion plus problem. That is also mentioned in the new firmware description. The firmware on my LN52A650 is 1003.m from 4/9/2008. Could I do more harm by updating it?......Thanks
