Guys, I've just purchased a used Ultimo 4k and want to flash over the current software, I've done what I always do with the USB (on 2 previous VU \receivers) and cold booted, I get the update message onscreen but the device reads the USB then continues to boot into the Openvix Willowbuild software.

The unit is on my LAN with only a single USB plugged in, I've formatted the USB (4GB) and use the same USB as always.... Any ideas what I'm doing wrong?

Many Thanks
