Combox Power LED flashes green, Status LED solid orange. Will not take upgrade.
After clearing the Combox internal memory, the Power LED will flash green and the Status LED will be solid orange.
If you have plugged a thumb drive into the Combox that has only ONE .bdl file saved to it, and the Combox does not
start a firmware upgrade after plugging in the thumb drive into the HOST port, it either means the thumb drive is not compatible,
or the .bdl file was not saved to your computer properly. Make sure you extract the folder, not just the .bdl file, or it can be corrupted.
