I'm just buy the new 55F6300 in Viet Nam. I would like to change region to EU or Italy UK in order to activate DVC-C tuner, however in the Region, I have only some Asia, American contry and these regions only activate DVB-T tuner. So I need to change the firmware to UK or not? and how to change the firmware? (I tried to use USB update with firmware from UK but not successful) .
I used IR to extended Service menu. Could you please advice ?
