Thanks Tema, if I understand properly I have to make my tv believe my laptop is the lg update server with some software and some DNS trick. Unfortunatly I am on a Mac so not sure it will work.. seems rather complex as well most likely going to wait for the official update too bad we can't simply update from a Usb key. but thanks anyway

Procedure to update via USB is:
1) Make in USB disk, folder named LG_DTV
2) Copy firmware *.epk in LG_DTV
3) Connect USB disk to TV


For LG store.

Make sure you take all agreements with LG and check if there an error in the address of the DNS server. Verify that no error in the country to use the TV.

In a pinch, call service support.

Thanks vkomitov will try to update through usd. when I get home! and I will report back (FYI I did check the dns settings for the wireless connection in the network section of the tv setup menu it is fine, I did accept all the agreement "from the about menu" and try different country with no luck...)
