hello again, a new problem has appeared in this madness that I have suffered since Saturday. The helix does not respond to the simultaneous pressing of buttons 6 and 12, which prevents me from entering update mode. It also does not react to other combinations. The firmware name, the red load line appears on the screen, but nothing else happens. Is there any way to totally reset the machine? I have installed old versions (2.91 and 2.92), from mac and PC ... and the result is the same. I have followed the steps of the technical service but I can't get anything ... Has something like this happened to anyone else? The device is new, it has not suffered shocks, electric shocks, humidity, smoke ... This is painfully strange!
