Abstract

Disclosed are a mobile terminal firmware version upgrade method and system. The method comprises: an upgrade tool conducting version validity check processing on a firmware version to be upgraded, and according to the version validity check result, sending handshake authentication information to a mobile terminal; the mobile terminal conducting handshake check processing on the upgrade tool using the handshake authentication information, and receiving the firmware version to be upgraded sent by the upgrade tool when the handshake check succeeds; and the mobile terminal conducting version validity check processing on the received firmware version to be upgraded, and conducting firmware version upgrade when the version validity check result is that the version is a valid firmware version.

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...
