thanks in advance for reading my first post

i ve just changed from SM the localization of my j6200 from ita to eu for enable shift time feature but i see that now in menu of transmission i can't launch a new research of channels, i can't launch a factory reset and i can't enter in the advanced settings of images menu because all these option are disabled.
anyone can help me or have any idea to have back these features? (first of all research for channels)
thank you all
