If the DVR recognizes there is a USB device (USB hard drives may not work), it will indicate a "Upgrade Software" button that you can use. I tried several times and often got "Upgrade Failed", so I eventually decided to unzip the image and place it on the same drive while switching to a smaller 32GB flash drive.
