Further, it can be determined whether the user data is the same, whether the manufacturer or the operator's customized application is the same, and if they are identical, no backup is required.

In this embodiment, using the switching unit to cut the version of the software operating system of the handheld terminal to the target switching version can be performed in the following manner: Entering the switching unit, selecting a software operating system version from the system data backup area, operating as a software The system target switches the version, extracts the data of the target switching version of the software operating system, and writes the data of the target switching version of the software operating system into the memory of the handheld terminal, and is used to run the target switching version of the software operating system.

In this embodiment, there are various ways to enter the switching unit. For example, when the handheld terminal fails to upgrade the software operating system, the handheld terminal actively enters the switching unit. The switching unit may also be entered according to the user's instruction, for example, the user is not satisfied. Actively enter the current software operating system Change the unit.

When the data of the software operating system includes the system data of the software operating system (the system data refers to the data necessary for the operation of the software operating system and some basic data) and the partition table information of the system data, the data of the target switching version of the software operating system is written. The storage area of the software operating system of the handheld terminal includes: the handheld terminal writes the system data of the software operating system target switching version to the specified memory space in the handheld terminal according to the partition table information. It can be seen that if the system data of the software operating system and its partition table information are saved, the process of switching the unit will be very simple. When the data of the software operating system includes the installation package of the software operating system, writing the data of the target operating version of the software operating system to the storage area of the software operating system of the handheld terminal includes: installing the installation package of the software operating system target switching version to In the storage area of the software operating system. Regardless of whether the data of the software operating system is the system data of the software operating system and the partition table information of the system data, or the installation package of the software operating system. Data is written or installed into the memory of the handheld terminal because the data is intended to allow the selected software operating system to operate.

If at step S102, at least one of the user data, the manufacturer's or the operator's customized data is backed up in the system data backup area. After entering the switching unit, the method further includes: storing at least one of user data, manufacturer, and operator customization data into the handheld terminal.
