Mobile terminal, method for uninstalling pre -installed application therein, and memory

A memory, storing a computer program that is executable to implement the following method steps:

• obtaining an authorization file for uninstalling the pre-installed application;
• determining whether the authorization file is valid;
• if the authorization file is valid, determining whether the pre-installed application is a user-level application;
• and
• if the pre-installed application is the user-level application, uninstalling the pre-installed application,
• wherein the authorization file comprises a configuration file and a signature file, and in obtaining the authorization file for uninstalling the pre-installed application, the computer program is executed to implement the steps of:
• obtaining configuration parameters of the mobile terminal;
• generating the configuration file based on the configuration parameters;
• obtaining abstract information of the configuration file;
• and
• encrypting the abstract information of the configuration file to obtain the signature file.

A mobile terminal, comprising a processor and a memory communicating with the processor, the memory storing a computer program, the processor configured to call the computer program in the memory to implement the following method steps:

• adding a user-level application directory in a storage space of the mobile terminal, and storing an installation package of the pre-installed application of the mobile terminal in the user-level application directory;
• obtaining an authorization file for uninstalling the pre-installed application, wherein the authorization file comprises a configuration file and a signature file;
• determining whether the authorization file is valid;
• if the authorization file is valid, determining whether the pre-installed application is a user-level application;
• and
• if the pre-installed application is the user-level application, uninstalling the pre-installed application,
• wherein in obtaining the authorization file for uninstalling the pre-installed application, the processor calls the computer program to implement the steps of:
• obtaining configuration parameters of the mobile terminal;
• generating the configuration file based on the configuration parameters;
• obtaining abstract information of the configuration file;
• and
• encrypting the abstract information of the configuration file to obtain the signature file.
