Hi all I’m new to the forum
Is there a way to downgrade thin os 9.0.4024 to 9.0.3030? Via WMS.
I don’t want to downgrade to thin os 8 via usb then upgrade to 9 again, as the devices are at a remote location.
Currently on thin os 9.0.4024 audio through the display port cable doesn’t work.
It works on 9.0.3030.
I tried to deploy the firmware to the device via WMS but the error I get is
Failed to install packages Error (failed to install root version 9.0.3030 package base version is not matched.
I have contacted dell who don’t have a solution.
Any suggestions welcome
Thanks
No the only way to downgrade is to use a merlin image and do it via USb install. That is one thing I do not like about WMS portal, cant downgrade, even though it gives you the option to do it, every time I done it, it failed as well
Thanks
