- Before upgrading from ThinOS 9.x to later versions, ensure that your system is powered on, and the sleep mode is disabled on the system.

To use the Wake-on-LAN command, ensure that the Wake-on-LAN option is enabled in the BIOS.
- You cannot boot into ThinOS 2311 (9.4.4123) or later versions when you perform the following operations:
1. Disable the onboard Network Interface Card (NIC), Trusted Platform Module (TPM), or Platform Trust Technology (PTT).
2. Clear TPM or PTT.
3. Reset BIOS to factory default settings.
- The upgrade may fail if the event log fails to install. In such an event, you may reboot the device and upgrade again.
- After upgrading to ThinOS 2205 or later, all application packages earlier than 2205 are removed automatically and cannot be installed again. You must install the latest application packages.
