Embodiment Construction

[0017] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0018] Step 100, the mobile phone is connected to the computer.

[0019] Typically, the phone is connected to the computer via a data cable.

[0020] Step 101, the mobile phone connects to the mobile phone firmware upgrade server through the PC application program.

[0021] Step 102, the PC application program reads the unique number of the mobile phone.

[0022] Among them, the unique number is the IMEI number, that is, the International Mobile Equipment Identity Number, which is an "electronic serial number" composed of 15 digits. It corresponds to each mobile phone one by one, and the code is unique in the world.

[0023] Step 103, the PC application program sends the unique number to the mobile phone firmware upgrade server.

[0024] Step 104, the mobile phone firmware upgrade se...

Abstract

The invention discloses a mobile phone firmware upgrade method, comprising the steps: S1, a mobile phone is connected with a computer and is communicated with a mobile phone firmware upgrade server by a PC application program; S2, the mobile phone firmware upgrade server sends encrypted mobile phone firmware to the PC application program; S3, the PC application program reads a secret key in the mobile phone to decrypt the encrypted mobile phone firmware; and S4, the PC application program upgrades the mobile phone firmware. The mobile phone firmware upgrade method enables the mobile phone firmware to be decrypted before upgrade because the mobile phone firmware is encrypted and the character sequence string generated by the unique IMEI number and upgrade requirement time is used as secret key. The mobile phone firmware can be upgraded safely and then the difficulty in cracking the mobile phone firmware is increased.

Description

technical field [0001] The invention relates to a firmware upgrading method, in particular to a mobile phone firmware upgrading method, which is suitable for mobile communication terminals such as mobile phones. Background technique [0002] In recent years, mobile phones have evolved from relatively simple voice phones to more complex multimedia communication devices. Today's cell phones typically feature text messaging, cameras, web browsers, conferencing capabilities, and other sophisticated functions. As mobile phones continue to add features, their firmware complexity also increases. [0003] Firmware is a type of software embedded in a hardware device. Usually it is in flash memory and can be updated by the user. Upgrading the firmware can generally make some enhancements to the functions of the mobile phone, fix some minor errors, make the mobile phone program run more smoothly, improve the quality of calls, and so on. [0004] Firmware upgrade refers to improving...
