Embodiment Construction

[0055] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0056] In the related art, since the terminal needs to read the boot program when running the first operating system, the boot program cannot be upgraded when the second operating system is upgraded. The operating system upgrade method provided by the embodiments of the present disclosure provides the following technical solutions: during the process of running the first operating system, download the system upgrade package; generate an updated boot program in the backup partition according to the system upgrade package, and the second Generate an updated second operating system in the partition; during the first reboot, overwrite the bootloader in the boot partition with the updated bootloader in the backup partition; during the se...

Abstract

The invention discloses an operation system upgrading method and device and a terminal, and belongs to the technical field of computers. The method includes the steps of downloading a system upgradingpacket in the process of running a first operation system, generating an updated guide system in a backup partition according to the system upgrading packet, generating an updated second operation system in a second partition, covering a guide program in a guide partition with the updated guide program in the backup partition in a first rebooting process, running the updated guide program in theguide partition in a second rebooting process, and guiding the terminal to make the updated second operation system run. By generating the updated guide system in the backup partition, copying the updated guide program in the backup partition in a terminal rebooting process and covering the guide program in the guide partition with the updated guide program, the problem that a guide program can not be upgraded when two operation systems are adopted in a terminal is solved, and the guide program is upgraded when the first operation system runs in the terminal.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to an operating system upgrade method, device and terminal. Background technique [0002] A terminal using an Android operating system has a bottom boot partition, and the boot partition stores a bootloader. When the terminal starts up, it first runs the boot program, and guides the terminal to run the operating system from the operating system partition. [0003] In the related art, two identical operating systems may be stored in the terminal, namely a first operating system and a second operating system. At this time, the method for upgrading the operating system is: download the system upgrade package while the terminal is running the first operating system; generate an updated second operating system according to the system upgrade package; restart the terminal, and run the boot program from the boot partition to guide the terminal to run An updated second oper...
