You can either do it manually or automatically. Go to your television’s Menu, then to support then to software updates, and finally to online. If your television can not get the right files or connect to the manufacturer’s (Samsung) servers, follow these steps to fix the problem:

  2. Extract the baseband content to a USB drive (view on Amazon) and connect the flash drive to your television
