[0048] With the development of science and technology and the continuous improvement of people's living standards, the use of various mobile terminals such as mobile phones is becoming more and more popular, and mobile phones have become an indispensable communication tool in people's lives.

[0049] As we all know, almost all electronic products have a factory reset function, which is used to restore the electronic products to the factory state. The main purpose of this operation is to erase user usage records, user data, etc., and restore the system configuration to the factory default state.

[0050] In the manufacturing process of existing mobile terminals such as mobile phones, the mobile phone needs to be tested. After the test, the factory settings function needs to be restored to restore the electronic product to the factory state. The main purpose of this operation is to erase the user's usage records and user data during the test and restore the system configuration to the factory default state.

[0051] In order to achieve factory reset, the current common practice is to format the user partition to erase all data generated by the user, such as data and configurations generated by applications, system configuration data, etc. This process clears the user data and the system restarts to load the system default configuration because no user data is found, thus achieving the purpose of restoring the factory settings.

[0052] From the above process, we can see that this process involves formatting the user partition, which is usually time-consuming. As the storage capacity continues to increase, this process usually takes several minutes to more than ten minutes. For factory batch production, each mobile phone needs to spend several minutes to more than ten minutes to restore the factory settings in order to clear the production test records before leaving the factory, which is time-consuming and laborious.

[0053] In order to solve the above problems, an embodiment of the present invention provides a method for restoring factory settings of a mobile terminal. According to the method for restoring factory settings of a mobile terminal of this embodiment, it can automatically identify whether the current working mode of the mobile terminal is factory mode or ordinary user mode. When various usage tests of the mobile terminal before leaving the factory are set to factory mode by default; the automatic factory reset mode (hereinafter referred to as factory mode) is set. When the electronic product is in this mode, the memory space is used as a virtual user space. Therefore, all user data will be stored in the virtual user space. Once the system is shut down or powered off, the data in the virtual space will be cleared to achieve the purpose of restoring factory settings. The present invention can effectively solve the above problems and greatly improve production efficiency.

[0054] Exemplary Methods

[0055] First embodiment

[0056] like Figure 1 As shown in the embodiment of the present invention, a method for processing a mobile terminal to restore factory settings is provided, and the method for processing a mobile terminal to restore factory settings can be used in mobile devices such as mobile phones and tablet computers. In the embodiment of the present invention, the method comprises the following steps:

[0057] Step S100: pre-set the factory mode and common user mode flags on the mobile terminal, and save the flags in the memory of the mobile terminal;

[0058] In the embodiment of the present invention, the factory mode and the ordinary user mode need to be set in advance on the mobile terminal before specific implementation; wherein, the factory mode (also called the automatic factory reset mode in this embodiment) is set to use the memory space as a virtual user storage space, and all user data will be stored in the virtual user storage space; and the ordinary user mode is set to store user data in the memory. That is, in the embodiment of the present invention, the factory mode is set to use the memory space to store user data. The ordinary user mode uses the mobile terminal memory to store user data.

[0059] The present invention will set the factory mode and ordinary user mode flags on the mobile terminal in advance, and save the flags in the memory of the mobile terminal. In the embodiment of the present invention, when the working mode is set to the factory mode, the factory mode flag will be automatically displayed, which is convenient for the system to read and obtain the factory mode.

[0060] In a preferred embodiment, in order to facilitate various tests and debugging of the mobile terminal before leaving the factory, the mobile terminal is pre-set to the factory mode by default before leaving the factory, and the flag of the default mode is set to the factory mode flag.

[0061] In the embodiment of the present invention, when the mobile terminal is burning or downloading system software, when the mobile terminal is set to the factory mode, the flag bit is set to the factory mode.

[0062] In the embodiment of the present invention, the flags of the factory mode and the common user mode are set, and the flags are stored in the memory (Flash) of the electronic product.

[0063] 1.1. For example, when the electronic product mobile terminal is burning or downloading system software, or when you want to set it to factory mode, set the flag bit to factory mode;

[0064] 1.1. Before the electronic product mobile terminal leaves the factory, the flag is set to the normal user mode (reading and writing the Flash flag is simple and easy to operate, and the time consumption is almost negligible).

[0065] Step S200, reading mode flag information from the memory when the mobile terminal system is started;

[0066] In the embodiment of the present invention, when the mobile terminal system is started, the mode flag information is read from the memory.

[0067] For example, before leaving the factory, the system starts up and reads the mode flag information from the Flash memory during the boot loader stage;

[0068] Determine whether the currently read mode flag information is the factory mode or the ordinary user mode. When the factory mode flag information is identified, the current working mode is determined to be the factory mode. Otherwise, it is the ordinary user mode.

[0069] Among them, Boot Loader is a small program that runs before the operating system kernel runs. Through this small program, hardware devices can be initialized and a mapping of memory space can be established, so as to bring the system's hardware and software environment to a suitable state, so as to prepare the correct environment for the final call to the operating system kernel. Usually, Boot Loader is heavily dependent on hardware implementation, especially in the embedded world. Therefore, it is almost impossible to build a universal Boot Loader in the embedded world. Despite this, some general concepts of Boot Loader can still be summarized to guide the design and implementation of user-specific Boot Loader.

[0070] For example, when the mobile terminal system starts up, the boot loader stage reads the mode flag information from the Flash and passes it to the Android kernel. When the Android kernel initializes the file system, if the flag information is the factory mode flag, it determines that the current working mode is the factory mode.

[0071] Step S300: when the flag information is determined to be factory mode, the memory space is mapped as a virtual user storage space to store user data when the file system is initialized; when the flag information is determined to be ordinary user mode, the user partition on the memory is mapped as a user storage space to store user data when the file system is initialized;

[0072] In an embodiment of the present invention, when it is determined that the current flag information is factory mode, the memory space is mapped to the virtual user storage space when the file system is initialized to store user data. For example, when a mobile terminal needs to do various usage tests before leaving the factory, the embodiment of the present invention can be set to perform various usage tests in the factory mode. When it is determined that the flag information is factory mode, the memory space is mapped to the virtual user storage space when the file system is initialized, and all user data is stored in the virtual user storage space, so that the initial factory settings can be automatically restored after the usage test is completed.

[0073] Of course, the flag bit can also be used to determine the normal user mode. When the flag bit information is determined to be the normal user mode, the user partition on the memory is mapped as the user storage space when the file system is initialized; all user data running in the current mode is stored in the user storage space of the memory, so that the stored user data is retained even when the power is off.

[0074] The embodiment of the present invention can be set to normal user mode when it is judged that it is not factory mode. The use of a two-choice judgment method can save judgment steps. When the flag information is judged to be normal user mode, the user partition on the memory is mapped as user storage space when the file system is initialized to store user data.

[0075] Step S400: When the mobile terminal is in factory mode and the system detects shutdown or power failure, the data in the virtual user storage space is automatically cleared.

[0076] In the embodiment of the present invention, when the system detects that the mobile terminal is turned off or powered off in the factory mode, the step of automatically clearing the data in the virtual user storage space includes:

[0077] When the mobile terminal detects that the flag is the factory mode flag, it is considered that the current working mode of the mobile terminal is in the factory mode. When the flag of the mobile terminal in factory mode detects shutdown or power failure, the data in the virtual user storage space is automatically cleared.

[0078] Reference to specific application examples of the present invention Figure 2 As shown:

[0079] Android system boot process The Android system boot process of the mobile terminal:

[0080] Preloader Preloader - Enter - A small program that runs before the operating system kernel runs. Through this small program, you can initialize hardware devices and establish a memory space mapping map, so as to bring the system's hardware and software environment to a suitable state. In an embedded operating system, BootLoader runs before the operating system kernel runs. You can initialize hardware devices and establish a memory space mapping map, so as to bring the system's hardware and software environment to a suitable state, so as to prepare the correct environment for the final call to the operating system kernel. At this time, the working mode Readmode: factory mode factory mode, or normal mode normal mode-------kernel operating system kernel------File system (rootfs) init file (root) system initialization (rootfs--->Root File System When the system starts, Uinx needs to open up a special file system rootfs in the memory to help the real file system successfully mount.) For example, Mount RAM to user space installs ram to user space.

[0081] In the embodiment of the present invention, the system starts up and reads the mode flag information from the Flash at the boot loader stage and passes it to the Android kernel; when the Android kernel initializes the file system, if the flag information is factory mode, the memory space is mapped as the virtual user storage space; if it is in normal mode, the user partition on the Flash is mapped as the user storage space.

[0082] As can be seen from the above, the present invention sets an automatic factory reset mode (hereinafter referred to as factory mode). When the electronic product is in this mode, the memory space is used as a virtual user space. Therefore, all user data will be stored in the virtual user space. Once the system is shut down or powered off, the data in the virtual space will be cleared to achieve the purpose of restoring the factory settings.

[0083] The present invention provides an implementation of factory reset based on the Android system, which is suitable for the production and manufacturing process of electronic products. From the perspective of effect, the method is no different from the ordinary factory reset. From the perspective of time consumption, it only requires the system to be shut down or powered off, which greatly improves the efficiency compared to the ordinary factory reset which takes several minutes to more than ten minutes.
