Go to the Groups & Configs page, and select a group.
From the Edit Policies drop-down menu, click ThinOS.
The Select ThinOS Configuration Mode window is displayed.

Go to Firmware Upgrade, and click Configure this item.
Clear the Disable Live Upgrade and Verify Signature options.
From the Platform Type drop-down list, select the platform.
From the Firmware to auto-deploy drop-down list, select the firmware added to the repository.
Click Save & Publish.
The firmware is deployed to the thin client. The conversion process takes 15-20 s, and the thin client restarts automatically.
