Downgrade to previous versions of ThinOS
If you want to downgrade to ThinOS 8.6 or 9.0 or you want to downgrade from ThinOS 9.1.3112 to the previous ThinOS 9.1
versions, disable the secure boot option in the BIOS setup. Downgrading from ThinOS 9.1 to previous ThinOS versions using
Wyse Management Suite is not supported. You can downgrade from ThinOS 9.1.3112 to ThinOS 8.6, 9.0 or ThinOS 9.1 previous
versions by using the USB Imaging Tool and Merlin Images posted on the www.dell.com/support site.
NOTE: If you want to downgrade to ThinOS 9.0, you must clear TPM or PTT in the BIOS and then use the USB imaging
tool and Merlin images to downgrade.
NOTE: You cannot downgrade from ThinOS 9.1.3112 to ThinOS 8.6, 9.0 or 9.1 previous version using Wyse Management
Suite.
NOTE: You cannot downgrade to ThinOS 8.6_606 or previous versions, if you are running the systems with SSD devices.
NOTE: You must install the application packages after you downgrade from ThinOS 9.1 to ThinOS 8.6 using Merlin Image.
