Juan Femenia

Hi dear friend. My name is Juan, I'm from Argentina. Sorry for my poor english. I'm writing you because of your topic "How To Downgrade webOS TV Firmware Tutorial". I need help please, cause my TV model is "49UF6400-SA" and I follow all the steps but not having any solution. Maybe it's because my model is not present in "local" or "online" folders. For that reason, I searched an updated version of LgDTVUpDater and I found this link: http://forum.ixbt.com/topic.cgi?id=62:22149#1 with the next download: http://nashdisk.ru/2d411c/ There's an updated version of those folders and maybe the folder "UF640" is the one for my TV model. But I don't know how to update all the program to use it. Please please please, can you help me? The actual firmware installed on my TV is 03.10.60 Thanks in advance!
