I have seen some past threads on DAC V1 firmware issues, but nothing covered how long it takes.
I have used the power on whilst holding buttons 1&3 process to force an update from the onboard copy, but it’s been at it a while now and I wondered how long it should take?
Other threads have suggested that it will automatically reboot once finished.
Ok, so I’ve had to power it all down anyway now.
We’ve just had a big Thunderstorm settle in on top of us, so everything off and unplugged for safety.
It was sitting at this screen for 2 hrs with no change before I took the decision to shut everything down and unplug it all.
OK, something definitely went wrong then.
I’ll see what I can do after tomorrow’s restart of the system.
Presumably it should allow me to try it again🤔
Experienced the same thing quite a few times, just give it some time after you switch it off completely, probably like 3-4 mins. Afterwards just hold again buttons 1 & 3, it will reboot and be back to normal once again. There is nothing wrong with it.
When I switched on this morning the firmware update started automatically.
It only took a couple of minutes and then restarted. Came back up straight away and all running fine now.
Thank you @realdpg for putting my mind at rest overnight
