● There are chances that after the upgrade the device displays a black screen. You may reboot the device to boot it up
correctly.
● When you upgrade from previous version of ThinOS 9.x to 9.1.3112, the thin client downloads all the application packages
that are applicable to 9.1.3112. After you upgrade to 9.1.3112, all the application packages are removed and you must reinstall
the application packages. Dell Technologies recommends you to upgrade from previous version of ThinOS 9.x to 9.1.3112
without installing the application packages. 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 low disk space. In this scenario, you must reset to
factory default settings for upgrading the ThinOS client again.
● If the thin client is registered in Wyse Management Suite group 1 and you set Wyse Management Suite group 2 token in
group 1 policy, then the group 2 token is applied on GUI but the thin client will still be in group 1. You must reboot the thin
client to change the thin client to Wyse Management Suite group 2.
NOTE: Dell Technologies recommends that you set a new 9.1 application package or a 9.1 OS firmware package in
Group 1, so that thin client installs the package, and automatically reboots, and changes to Group 2.
● When you set a new firmware or an application package in Wyse Management Suite group 2 and then change the device
from group 1 to group 2 before upgrading, the following two notifications are displayed:
○ Wyse Management Suite server or group is changed. System is going to reboot to load full configuration.
Press cancel in 60 seconds to prevent reboot.
○ A new firmware or application is available, do you want to upgrade now or defer to the next reboot? The
changes will automatically be applied in 120 seconds.
If you do not select an option, the thin client reboots after 60 seconds. After reboot the new application or firmware is
installed and the thin client reboots again.
●
If the Live Update option is disabled, the thin client cannot download and install any firmware or package until the next
reboot. However, the firmware or packages are downloaded in the following scenarios even when the Live Update option is
disabled:
○ When you register the thin client to Wyse Management Suite manually.
○ When you power on the thin client from a power off state.
○ When you change the Wyse Management Suite group.
● When a new firmware or an application notification is displayed on your thin client, clicking Next Reboot will:
○ Displays a notification if you have changed the Wyse Management Suite group and if the files are downloaded from the
new group.
○ Displays a notification if the new firmware or application is downloaded in the same group.
○ Installs the firmware or package after a reboot.
● ThinOS 9.1 does not apply OS firmware application package and BIOS firmware in child Select group.
● ThinOS 9.0.1136 firmware cannot be upgraded, or new application packages cannot be installed on ThinOS 9.0.1136 after
September 2021. You can disable time server on ThinOS, change the system time to August 2021, then upgrade the
operating system firmware or install the application packages. Dell Technologies recommends you to upgrade to ThinOS
9.1.1131 or later version when the issue is fixed. For more information about how to upgrade from ThinOS 9 to a later version
using Wyse Management Suite, see the Dell Wyse ThinOS Version 9.1 Migration Guide at www.dell.com/support.
Upgrade to ThinOS 9.1.3112 from ThinOS 8.6 using Wyse
Management Suite
If you are running ThinOS 8.6 version, you must first install the ThinOS 8.6_807 image with the latest BIOS version, and then
upgrade to ThinOS 9.1.3112.
The device reboots after the ThinOS image is downloaded. Once the upgrade completes, the device is automatically registered
to Wyse Management Suite. For information about how to update the settings, see the Dell Wyse ThinOS Version 9.1 Migration
Guide at www.dell.com/support. Dell Technologies recommends you to back up your device settings before you initiate the
upgrade process.
NOTE:
