Great forum and great hack, bought this set this week and glad to find it had 1119 firmware so happily have root on this to play around with

I wanted to prevent automatic firmware updates and read the following article.

Just wondering if this is necessary as there was an option in the menus to switch autonmatic updates off.
I've switched it off here but just wonder if this is sufficient?
Thanks in advance
