I did exactly as you said, but still have my Amplifi 75 (2.60) in recovery mode on boot with 4 flashing lights. I tried Apple Pi-Baker, Etcher, DMDE on Mac and DMDE for Win64, then updated firmware via Mac or PC many times and got the same result. I could get the bluetooth link and start update procedure via Line 6 Remote App but it freezes again and again. Any ideas?

It looks like this is not a bootable image :(
