Samsung B6000 No USB Movie playback after firmware upgrade

[abhifusion]

I just upgraded the firmware of my 40" B6000 LED TV (002004 to 002005) and now it dont show movie option when i plug in the USB stick ... I rolled back to previous version too , but still it dont show the movie option !!

I was able to play mkv , avi etc movies through the USB before , how to get it back ?? Please help !!
I cant get into service menu , tired info+menu+mute buttons after switching off the TV but it again switcho n into normal mode ...

I'll never upgrade the firmware now

Why did you upgrade the firmware? Did you get the newer firmware off Samsung's link or was this a custom one?
