I've just bought a secondhand montage
I've downloaded version 2 from the yamaha website. I formatted various USB2 and USB3 devices on the montage itself but cannot update the firmware.
When I go to update pressing cursor up and utility, it just gets stuck on "searching for the updater...NG" Press (INC/YES to retry)
The montage recognises the usb stick in the utilities memory
The file is 8N70OS_.PGM
I have downloaded it a few times on my iMac running High Sierra 10.13.4
I'm stuck in this endless loop. I am currently on OS 1.51.1
