Embodiment Construction

[0020] In order to make the object, technical solution and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] In the embodiment of the present invention, when the mobile terminal is started, the Bootloader will guide the 512-byte MBR partition of the EMMC. MBR is used as the initial boot partition for the mobile terminal to start. If there is no such partition or this partition is damaged, the mobile terminal will not be able to boot . Therefore, in the embodiment of the present invention, the MBR partition is solidified in the SIM card of the user's own mobile terminal, and the MBR data is not stored in the EMMC. In addition, the MBR data is also synchronized to the server. Once the MBR ...

Abstract

The invention is suitable for the field of mobile terminals and provides mobile terminal startup method and system, and a mobile terminal. The method includes following steps: when the mobile terminal receives a startup instruction, detecting whether information reading of a terminal SIM (subscriber identity module) card is normal or not; if not, not responding to the startup instruction; if yes, verifying MBR (master boot record) data in the terminal SIM card; if verification succeeds, normally starting up the mobile terminal; and if the verification fails, not responding to the startup instruction. Startup verification and prevention from refurbishment to protect data are realized by binding the mobile terminal with the SIM card through storing the terminal MBR data in the SIM card.

Description

technical field [0001] The invention belongs to the field of mobile terminals, and in particular relates to a method and system for starting a mobile terminal and the mobile terminal. Background technique [0002] In the prior art, after the mobile phone is lost, the power-on password can be used to prevent theft, but the mobile phone can continue to be used normally after being flashed, so that the original mobile phone user data is easily lost. In addition, mobile phone passwords are easy to crack, and some users are even reluctant to set passwords for convenience. In this way, it is difficult to retrieve the lost mobile phone and the data stored in the mobile phone, and its security is poor. Just can continue to use normally, thereby make those criminals profitable. To sum up, the prior art cannot prevent the illegal flashing function, which makes mobile phone user data easy to lose, and its security is poor. Contents of the invention [0003] The purpose of the prese...
