How to restore to the backup Firmware?

Hey, I ran into a similar issue while working on costcofoodcourtmenu.com sometimes updates break things, and rolling back is the only fix. If your device doesn't have an auto-backup option, I'd suggest reaching out to support to get the 2.0.16.0 firmware file. That's what I did when I had to restore an older setup for my site. Once you have the file, you should be able to upload it manually. Hope that helps!
