: This means the firmware is designed to be installed via a USB flash drive (Plug & Play update).
: Copy only the .bin file directly onto the USB drive (not inside any folders). Update the TV : Unplug the TV from power. Insert the USB drive into the TV's USB port. Plug the TV back in.
: Use a drive with a capacity of 4GB or 8GB and format it to FAT32 .
