Mmrinmoy, I don't know how it actually works. I guessed that because I turned my TV off a little after 1:30AM last night, and only turned it on this morning around 8-ish to find that message. But it was useless, I couldn't get it updated nor could I watch TV unless I cancelled the update.
So, it's gone (for now), and hoping it would come back soon.
What are the features you all looking forward to with this update? Apart from USB recording and Dolby through HDMI?
My wish is that they improve their EPG a little better; I can't search for the shows which I have set reminder for at one place. This is incredibly annoying if you want to cancel a reminder.
