I have a GLD112 mixer, after I updated the firmware it immediately couldn’t turn on at all. Please help
Yup, has happened to me in the past and had to send the whole thing out for SSD replacement and reload. It’s a shame they don’t make it easier to reload the system without having to send it out. Might suggest opening a case with support and seeing if they can help you with any suggestions. My only suggestions would be just to try a number of times and maybe remove all accessories, dsnake connections, I/O card, remove power for a bit, etc and see if you can get it to boot with nothing attached/connected.
