The ZTE Terminal Software Update Framework is a software tool developed by the Chinese telecommunications company ZTE. It is designed to simplify and secure the process of updating system software on ZTE devices, such as routers, dongles, smartphones, and other terminal equipment. The framework includes several components and executables, such as ZTE_Sales_Update_Framework.exe , adb.exe , UsbDeviceManager.exe , and CMUpdater.exe . The latter, CMUpdater.exe , is a digitally signed program that runs in the background to check for updates on Windows-based devices.
