Hello, I?ve moved to Florida, in the United States from Spain and I brought two UE40ES5500. I tried in Service Mode and with the ruSamsung pressing Factory and 3Speed, in this way I can change the Region, but I have whole Europe, Middle East, part of Africa and Asia, Australia, New Zealand... But in America I only can see Center America countries, I can?t find any channel in DTV (there are a lot, I checked with a local LG tv), and even there are some Apps, like VUDU that doesn?t work.
Can you help me to change the Region?
Thank you
