Dell ThinOS 2211, 2208, and 2205 Administrator’s Guide

Upgrading the ThinOS firmware

It is recommended to use the Wyse Management Suite version 3.7 or later to upgrade your ThinOS firmware to the latest 9.x version. You can also use the USB Imaging Tool version 3.4.0 or later to install the ThinOS Merlin image on your thin client.

The overall upgrade process using Wyse Management Suite includes the following tasks:

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.
Download the ThinOS operating system image. See Download the ThinOS firmware.
Upgrade BIOS on your device to the current version mentioned in the BIOS details table in this section.
Upgrade the ThinOS firmware from 9.x to later versions. See Upgrade ThinOS 9.x to later versions.
Deploy the application packages. See Upload and push ThinOS 9.x application packages.

The following firmware upgrade scenarios are supported for upgrading to the latest ThinOS version:

ThinOS 9.1.3129 or later versions > ThinOS YYMM

From ThinOS version 9.1.6108, the following changes are made in the installation process:

The pop-up window for new firmware or application package is prompted before downloading the file. After you click Install Now, the download is initiated.
Once a file is downloaded, it gets installed before the next file is downloaded. After the installation of the downloaded file is finished, the next download is initiated.
ThinOS image is downloaded and installed first. The client reboots after the image is installed. After the reboot, the download and installation of other packages are initiated.

From ThinOS 2303, Servicing mode has been added to the installation process. The following changes can be observed as part of this addition:

Updated the order from OS > BIOS > Application to BIOS > OS > Application. After BIOS update, ThinOS reboots and then continues to update the operating system. After operating system update, ThinOS reboots and then continues to update the application.
Removed the bottom-right download progress window. The operating system and BIOS downloads in the background and is installed in servicing mode. Applications are both downloaded and installed in servicing mode.
When ThinOS enters servicing mode, ThinOS automatically logs off when you are logged in. You cannot log in until the update process is finished.
If the update fails, ThinOS automatically exits servicing mode after a countdown. You can also click Exit to exit the mode manually. After exiting the servicing mode, you can log in to continue your work.
The applications that fail to update are displayed in the failed application list.
If you update an invalid application package, like trying to install an application released prior or as part of ThinOS 2205, the update fails. Reboot your device and the device does not download and install the invalid application package again.
If you do not connect power adapter to the ThinOS client, the update fails with a 60-seconds countdown error AC power is not connected.
- If you connect the power adapter in 60 seconds, ThinOS exits servicing mode and then enters servicing mode again to continue the update process.
- If you do not connect the power adapter in 60 seconds, ThinOS exits servicing mode after the countdown is complete. You must reboot and update again.
If the network disconnects during application package download, ThinOS waits for 45 seconds
- If network is recovered in 45 seconds, the current downloading application package is ignored and the next application package begins to install. After the other application packages are updated, the client automatically reboots and downloads the application package that was not downloaded in the beginning.
- If network is not recovered in 45 seconds, a message is displayed stating that the application package list has failed to install. You can connect network and reboot to update again.

If you change the WMS server or group in the Central Configuration window when there is a notification window with a new available firmware or application package upgrade, a pop-up window is displayed to notify that the upgrade will be terminated.

For detailed information about the upgrade process, see the latest Migration Guide at www.dell.com/support.

NOTE:If the package fails to update, or if the thin client does not work after upgrading to the new firmware, remove all packages and reboot the thin client. Reinstall the package after the reboot.

NOTE:To optimize security, application performance, and stability, a design change has been made in ThinOS 2205 when installing third-party applications, like Citrix Workspace App, VMware Horizon, and Microsoft AVD. Third-party applications released as part of ThinOS 2205 use a different shared library search path than older third-party package versions. Because of this optimization, third-party packages that are released before ThinOS 2205 are no longer supported with ThinOS 2205 or later versions. Install the latest version of the required third-party application after you upgrade to ThinOS 2205 or later versions.

NOTE:Third-party packages released before ThinOS 2205 can be downloaded but installation fails on the first attempt. After that, the packages cannot be downloaded anymore.
