Error 606 to update firmw

[hmosquera]

Hello, i m from Argentina, and i have a Samsung UN46D6400
CODE MODEL: UN46D6400UGCDF
NUMBER OF VERSION: CN01
NUMBER OF VERSION: UN46D6400UGXZB

My firm version is 001010, and my problem is when i try to run netflix app, The app requieres me firmware update, but when i try to do so (via wifi) , an error 606 window appears.
Also, i tried to download the firm via oficial website to argentina, but there is no firm available.
Can i use the latest US firm downloading it from the oficial US website? Do i have to take any precaution?
Thks for advance.
