US 2026/0017045 A1 · OPERATING SYSTEM UPGRADE METHOD AND ELECTRONIC DEVICE

Abstract

This application discloses an operating system upgrade method and an electronic device in the field of computer technologies. The method involves loading a basic partition, a first static partition, and a dynamic partition to run a first version of the operating system. It obtains a first installation package for a second version, which is lower than the first version, containing first and second system data. The first system data is written into a second static partition and a user data partition. The device then reboots into repair mode, writing the second system data from the user data partition into the dynamic partition and formatting the user data partition. Finally, it reboots to load the basic partition, second static partition, and dynamic partition to run the second version of the operating system. This allows the electronic device to automatically roll back to a lower version without needing service outlet intervention.
