Do you see a message on the TV after you power on while repeat pressing the menu button that says "USB Upgade, Do not power off"
If you do not see this then the USB flash.bin is not working.
You need to use a fat32 USB less than 32Gb.
Use the .bin file from inside the .zip folder to rename as flash.bin.
