Upgrade Thin OS to 9.4.4123

Hi,

I am trying to upgrade Wyse 3040 to Thin OS 9.4.4123 but after the file has been downloaded and the installation process started, it ends up with a message saying installation failed. No more details.

I am using WMS 4.1.1 111.

Package used:

Thin OS 9.4.30.87

Citrix Workspace 23.8.0.39.1

Zoom Citrix 5.15.2.23760.2

I did create a group to clean up the Wyse, to uninstall Citrix, Zoom, but I cannot select the file to uninstall in the list.

Any help would be appreciated.

Thank you.

PS: I saw this package (ThinOS 2311 (9.4.4123) disk cleanup utility) on the website, but it says ask Dell support to get info about it. I guess this would solve my issues but how to use it?

We had a similar issue and the fix were to write the Wyse 3040 over with a Merlin image from a USB boot.

All files to create the Merlin image USB boot are available from the Dell Support website.

The Merlin image creates a new factory preset for your 3040 and the newer version will be compatible with WMS initiated ThinOS upgrades.
