My TV shows 999999 as well, this is normal for TV that wasn't updated before. Go to SW update and press info key on you remote to get current FW version ( bottom of the screen)
Having read some posts here and also on Samsung.com I?ve decided to update the firmware on our LN40A750.(This LCD TV has a build date of June 2007) One of my first thoughts was ?Is there a way to save the current firmware??. If not, then maybe I should not do the update?but, what the heck?
I downloaded the new firmware, copied and unzipped it (14 files) to a thumb drive. I then, following the instructions, plugged the thumb drive into the TV and started the update, but when the message came up ?Upgrade version 999999 to version 1012.2?? I stopped. Obviously the Version 999999 is incorrect, or is it? Should I have disregarded the ?999999? message and gone ahead with the update or not????
