Important Information
- Flash protection reliability enhancements are added to reduce wear and extend flash life. Dell Technologies recommends that you upgrade to ThinOS 9.1.2101 to use these enhancements.
- If you are using ThinOS 9.0.1136, you cannot upgrade the ThinOS firmware or install application packages after September 2021. You must disable the time server on ThinOS, change the system time to Aug 2021, and then upgrade the ThinOS firmware or install the application package. Dell Technologies recommends that you upgrade to ThinOS 9.1.1131 or later versions at the earliest.
- Do not power off your thin client until the installation is complete.
- If you are downgrading ThinOS 9.1 to ThinOS 8.6, or ThinOS 9.0 you must use the Dell Wyse USB Imaging Tool to install the ThinOS 8.x or 9.x image. Before you downgrade, ensure that you disable the secure boot option, and also clear Trusted Platform Module (TPM) or Platform Trust Technology (PTT) in BIOS. Else, ThinOS 9.0 resets to factory settings after each reboot.
- Do not enable video call for Citrix unified communication optimization features on the Wyse 3040 Thin Client. Video call results in performance issues.
- You cannot boot into ThinOS 9.1 when you perform the following operations in BIOS setup: Disable onboard Network Interface Card (NIC), Trusted Platform Module (TPM), or Platform Trust Technology (PTT), or clear TPM or PTT, or reset BIOS to factory default.
- You cannot install ThinOS 9.0 application packages on ThinOS 9.1 due to certificate change.

Installation instructions
This image is intended for customers who want to upgrade from ThinOS v9.1 to ThinOS v9.1.2101.

Prerequisites

The Configuration Control | ThinOS window is displayed.
3. In the left pane, click Standard.
4. From the Standard menu, expand Firmware, and click OS Firmware Updates.
