I've taken over a DVR for a friend of mine, they are having issues with it crashing daily trying to do an "Upgrade please do not turn off"
Basically, the DVR locks up during this and doesn't respond to any input, the only fix is to turn the power off and on, the DVR then returns to normal operation.
I've had a look on the QVIS website for the Quattro DVR, they have a fair few DVR firmware available for the range. https://support.qvisglobal.com/hc/en-us/articles/360000142632-Quattro-Quattro-Pro-4X-4X5-Q4-Firmwares
I can't make much sense out of it, I don't want to apply one of these randomly and have it brick the DVR completely.
Some more details about this particular DVR.

Does anyone know what Firmware this DVR needs? or how to find out?
