Problems solved by technology

If the userdata partition is encrypted and the system upgrade package is located in the encrypted userdata partition, the encrypted userdata partition cannot be mounted, so the system upgrade package located in the encrypted userdata partition cannot be run. At this point the system upgrade will fail

Embodiment Construction

[0019] In order to make the objectives, technical solutions, and beneficial effects of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0020] The term "and / or" in this text is only an association relationship that describes the associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: A alone exists, A and B exist at the same time, exist alone B these three situations. In addition, the character " / " in this text generally indicates that the associated objects before and after are in an "or" relationship.

[0021] In the embodiment of the present invention, the term "terminal" may be a mobile phone terminal, a personal computer (PC for short) terminal, a tablet ter...

Abstract

The embodiment of the invention relates to the field of the computer technology, in particular to a system upgrading method and device. The system upgrading method and device is used for upgrading a system when equipment which stores a system upgrade package is encrypted. In the embodiment of the invention, in a process of entering a recovery mode, when physical equipment which stores the system upgrade package is determined to be under an encryption state, logical equipment corresponding to the physical equipment is created, the identifier of the equipment which stores the system upgrade package in a recovery partition table is changed into the identifier of the logical equipment from the identifier of the physical equipment, and therefore, the logical equipment is mounted when the recovery mode is successfully begun so as to avoid the problem in the prior art that the encrypted physical equipment needs to be directly mounted. In addition, since the logical equipment is not encrypted, the logical equipment can be successfully mounted, and then, the logical equipment can be used for calling an encryption interface to access the system upgrade package stored on the physical equipment.

Description

Technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular to a system upgrade method and device. Background technique [0002] With the continuous development of communication technology, terminals such as computers and smart phones have become more and more popular. The built-in system in the terminal is usually an open source system. Due to the constantly changing usage requirements, the built-in system in the same terminal often needs to be continuously upgraded. For example, the firmware operating system of a smartphone is Android 4.4 when it is shipped, and it will be upgraded to Android 5.0 or later. [0003] There are many forms of system upgrade, the most common is Over-the-Air Technology (OTA) upgrade. But in order to increase the security of Android terminal devices, the device encryption function has been introduced since Android4.4. For example, the user data (userdata) partition on the Android termi...
