Method and system for preventing mobile terminal from being updated to illegal firmware version

Abstract

The invention discloses a method and a system for preventing a mobile terminal from being updated to an illegal firmware version, relating to the field of firmware updating of the mobile terminal. The method comprises the following steps: carrying out version legality verification processing on the firmware version to be updated by an updating tool; transmitting handshaking authentication information to the mobile terminal according to a version legality verification result; carrying out handshaking verification processing on the updating tool by utilizing the handshaking authentication information of the mobile terminal; receiving the firmware version to be updated issued by the updating tool according to the handshaking verification result; carrying out the version legality verification processing on the received firmware version to be updated by the mobile terminal; and carrying out firmware version updating according to the version legality verification result. With the adoption of the method and the system, users are prevented from updating the mobile terminal to the legality firmware version which is unidentified in sources and can influence the mobile terminal to be used, so that normal working and use of the mobile terminal can be effectively guaranteed, and benefits of users and operators are also guaranteed.

Description

technical field [0001] The invention relates to the field of mobile terminal firmware upgrades, in particular to the technology for preventing illegal firmware upgrades. Background technique [0002] A mobile terminal, also known as a mobile communication terminal, refers to a portable mobile computer device, broadly speaking, including a mobile phone, a data card, a tablet computer, and the like. [0003] Firmware refers to the software responsible for the most basic and bottom-level work of a digital product. It is generally stored in the EEPROM or FLASH chip in the device, and can be upgraded by the user through a specific firmware upgrade tool. [0004] The firmware upgrade tool refers to auxiliary software used to upgrade the firmware version on the mobile terminal. [0005] Since the firmware version is closely related to the terminal hardware, the firmware of early mobile terminals can generally only be provided by the manufacturer. Manufacturers will go through det...
