Abstract

Disclosed are a firmware upgrade method and device. The method comprises: backing up a partition table of a system and a minimum starting item of the system in a preset backup region, modifying a partition address of the minimum starting item in the partition table of the backup region as a partition address of the minimum starting item in the backup region, and modifying a system index value as the backup region; and downloading a new partition table and a new minimum starting item, and in the case where the downloading of the new partition table and / or the downloading of the new minimum starting item has failed, when the device is restarted, finding the backup region according to the system index value, and according to the partition table and the minimum starting item backed up in the backup region, guiding the device to start in accordance with an old version, and performing recovery firmware upgrade again. By means of the technical solution of the present invention, in the case where the system firmware upgrade has failed, the system can still be normally started.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a firmware upgrading method and device. Background technique [0002] With the continuous development of communication technology, user terminal equipment (such as mobile phones, data cards, CPE, etc.) has become popular in people's daily life and has become an indispensable communication tool in modern life. Information sharing played an important role. In the actual application process, it is often necessary to upgrade it due to the failure of the manufacturer to modify the version or to add new applications. [0003] Many current products already have the device upgrade function, but during the upgrade process, if the user terminates abnormally or encounters abnormal conditions such as power failure, the version update will fail and the device will become abnormal. The current upgrade method has the following defects in terms of performance: 1. It does not contain an upgr...
