Found that a later fw, mine is 20170510, says that is supports QR scanning, so maybe this is the issue.
However, I try to add the dav file to the root of a SanDisk Extreme 64GB XC I I Class 3 Micro SD and it doesn't seem to do anything - no voice to say it's upgrading or not, so not sure if the card is incompatible, or the unit is just busted. Does it need to be formatted in EXT? Has anyone upgrade firmware before on this device, and what happens when the unit is rebooted?
