I just got it going. I did not realize a .7z file was a zip! Thank you for the help!If you have the listed build software that can be upgraded, download it and unzip. If you leave all the contents in the folder and drag that over to a USB drive the system won't recognize it. I had the same issue. I dragged the items inside the folder to the USB drive directly and it worked. I then followed the linked service bulletin steps, fairly straight forward. If you don't have the listed software, none of this matters, you'll have to figure out if your software even has an update available.
