Problems solved by technology

[0003] Since most mobile phone manufacturers will not directly expose the ISP interface, usually to find these ISP points requires a detailed hardware circuit of the mobile phone motherboard, or test point by point on the mobile phone motherboard, which is not only time-consuming but also a lot of work. Greatly affects the user experience

Abstract

The present invention proposes a mobile phone unlocking method and system based on chip disassembly of the present invention. The system includes: a font chip disassembly subsystem, used to disassemble the font chip from the mobile phone; The mobile phone system file in the font chip is modified to remove or shield the unlocking password, and then the unlocked font chip is installed into the mobile phone by using the font chip removal subsystem. The present invention provides a set of chip-level unlocking schemes from dismantling to recovery. According to the model type of the mobile phone, the position of the card seat of the mobile phone motherboard and the position of the air gun are automatically set, and the temperature curve of the air gun is automatically set. Remove the font chip or restore the font chip; adopt high-speed reading and writing equipment and online file modification technology, and modify the data of the mobile phone chip according to the mobile phone model to achieve the purpose of unlocking.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a method and system for unlocking a mobile phone based on chip removal. Background technique [0002] In the process of mobile phone forensics and identification, unlocking is the first step in all work. The current unlocking method is to use ISP (In-System Programming, in-system programmable) technology to directly find test points on the main board of the mobile phone that can be connected to the CLK, CMD, DATA0 pins on the font chip or other available soldering points. , the flying wire is connected to the external programmer to complete the online modification of the system data so as to achieve the purpose of unlocking the mobile phone. [0003] Since most mobile phone manufacturers will not directly expose the ISP interface, usually to find these ISP points requires a detailed hardware circuit of the mobile phone motherboard, or test point by point on the mobile phon...
