Provided are a device and method for upgrading a data terminal. The device includes a dialing component, a protocol component, a DHCP Dynamic Host Configuration Protocol (DHCP) server component, a router component, an Internet Protocol (IP) processing component, an upgrading component and a web server component, wherein the dialling component implements a dialling flow; and the upgrading component acquires a private IP address from the DHCP server component, sends a request message of detecting whether there is a new version to a version server through the router component and the protocol component, and if there is the new version, downloads the new version from the version server and writes the new version into a flash of a data terminal, and then the data terminal is automatically restarted to finish upgrading. According to the technical solution, an upgrading process of the data terminal under a win8 operating system, a web server access process and a network access process of a Personal Computer (PC) are independently implemented, relevance between the upgrading process of the data terminal and an operating system of the PC is reduced, Microsoft win8 logo authentication can be passed, and a driver-free function may further be realized. |
