Upgrading the ThinOS firmware
It is recommended to use the Wyse Management Suite version 3.1 or later to upgrade your ThinOS firmware to 9.1. You can also
use the USB Imaging Tool version 3.4.0 to install the ThinOS 9.1 Merlin image on your thin client. If you are using ThinOS v8.5
or earlier versions, you must first upgrade your device to ThinOS v8.6 before installing ThinOS 9.1. ThinOS 9.1 displays a change
group notification message on the device after you change the group in Wyse Management Suite. A new firmware or package
message is also displayed when you deploy a new firmware or package using Wyse Management Suite.
NOTE: All device settings are erased after you upgrade from ThinOS 8.6 to 9.1 except the Wyse Management Suite server
settings, wireless connections, wireless certificates, and proxy settings. You must back up your device settings before you
start the upgrade process. Once upgraded to ThinOS 9.1, you can downgrade to ThinOS 8.6 only by using the Merlin image.
When you upgrade from ThinOS 9.0 to 9.1, the thin client downloads all the application packages that are applicable to 9.1. But
after upgrade to 9.1, all the application packages are removed and you must reinstall the application packages. Dell Technologies
recommends that you upgrade from ThinOS 9.0 to 9.1 without the installation of any application packages.
NOTE: If you add multiple application packages along with the operating system image in the same Wyse Management
Suite group, the upgrade may fail due to the low disk space. In this scenario, you must reset to factory default settings for
upgrading the ThinOS client again.
The overall upgrade process using Wyse Management Suite includes the following tasks:
1. Register your thin client to Wyse Management Suite.
● Register ThinOS devices using Central Configuration. See Register ThinOS devices using Wyse Device Agent.
● Register ThinOS devices using DHCP option tags. See Register devices by using DHCP option tags.
2. Download the ThinOS 9.1 operating system image. See Download the ThinOS firmware.
3. Upload the ThinOS 9.1 firmware to the Wyse Management Suite repository. See Add ThinOS firmware to repository.
4. Upgrade the ThinOS firmware from 8.6 to 9.x. See Upgrade ThinOS 8.6 to ThinOS 9.x.
5. Upgrade the ThinOS firmware from 9.x to later versions. See Upgrade ThinOS 9.x to later versions.
NOTE: You must first upgrade to 9.1 base image, and then install other application packages.
6. Deploy the application packages. See Upload and push ThinOS 9.1 application packages.
For detailed information about the upgrade process, see the Dell Wyse ThinOS 9.1 Migration Guide at www.dell.com/support.
NOTE:
You cannot boot into ThinOS 9.1 when you perform any of the following operations in BIOS setup:
● Disable the on-board Network Interface Card (NIC), Trusted Platform Module (TPM), or Platform Trust Technology
(PTT).
● Clear TPM or PTT.
● Reset BIOS to factory default settings
