Abstract

The disclosure discloses an operating system upgrading method, device and terminal, belonging to the technical field of computers. The method includes: downloading a system upgrade package during the running of the first operating system; generating an updated boot program in the backup partition according to the system upgrade package, and generating an updated second operating system in the second partition; In the first restart process, the boot program in the boot partition is covered by the updated boot program in the backup partition; in the second restart process, the updated boot program is run from the boot partition, and the terminal runs the updated second boot program. operating system. This disclosure generates an updated boot program in the backup partition, and copies the updated boot program in the backup partition and overwrites the boot program in the boot partition during the terminal restart process. The problem of program upgrade realizes that the terminal upgrades the boot program when running the first operating system.

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...
