Problem with D250 Pro after the upgrade

[AlexS]

Sorry to hear about your trouble after the Pro upgrade. I can't help unfortunately as my upgraded 250 has behaved apart from one time where an 'over voltage' was reported after a brief stop in sound. This may be true, but I think it is more likely to be caused by heat as the amp now gets warmer than before the upgrade.

Was it faulty immediately, even before the 10.1 upgrade? Good thing you managed to read the error codes, it really sounds like the amp will have to go back to France. Hope Devialet reacts promptly on this one. Good luck!

Yes, it was faulty immediately, even before I inserted the memory card with my config file.
An interesting thing is that I can make the problem temporarily go away, if I disconnect the unit from the mains, and then power it back again (or, for that matter, the long power button press, which turns off the menu, also does the trick). Then after a while, the problem is back.
If it has to go back to France, it will. Thank you for the compassion (I need it)
