A kind of non-smart mobile phone and the method for upgrading its system program

Abstract

The invention provides a non-intelligent mobile phone and a method of upgrading the system program thereof. The mobile phone comprises an SD card storing a system upgrading program of the mobile phone, and a clock-module marker register. The method comprises the following steps: detecting whether a specific combination key of the mobile phone is pressed via a guiding program when the start-up of the mobile phone is detected; writing a flag bit of a backup mode into the clock-module marker register and operating the system program when the specific combination key is pressed; determining whether a flag bit of a download mode is in the present clock-module marker register when the specific combination key is not pressed; operating the system program if the download mode flag bit is not in the present clock-module marker register; and reading the upgrade program in the SD card and saving, and writing a flag bit of a recovery mode into the clock-module marker register and starting the mobile phone, if the download mode flag bit is in the present clock-module marker register. The method for upgrading the system program can upgrade the system programs of non-intelligent mobile phones.

Description

technical field [0001] The invention belongs to the field of mobile communication, in particular to a non-smart mobile phone and a method for upgrading its system program. Background technique [0002] With the development of handheld mobile terminals, users have more and more requirements for mobile terminal functions, which are more and more complex, which makes the demand for mobile terminal system software upgrades also increase. Users often expect to obtain newer and richer applications, but the complexity of the application program will also increase the probability of defects in the system program of the mobile terminal. For example, if the current system program cannot support certain application programs, the application program cannot run, and the functions corresponding to the application program cannot be used. Usually, only upgrading the system program can solve these problems. [0003] In the prior art, upgrading the system program usually needs to be connecte...

AI Technical Summary

Problems solved by technology

The inventor of the present invention found in the process of researching and experimenting on the prior art: due to the need for equipment such as computers and data lines, the requirements for hardware equipment are relatively high, and secondly, specific application software and drivers need to be installed, and there may be drivers The problem of program incompatibility, and the operation is cumbersome, which is not convenient for users to operate

And in the prior art, there is a scheme for upgrading the system program of the smart phone through the SD card, but the inventor finds that the upgrade method of the smart phone using the SD card cannot be used for non-smart phones (also known as feature phones (Feature Phone). )) system program to upgrade
