Abstract

The invention discloses a differential upgrade method, a storage medium and a mobile terminal for a mobile terminal. The method includes: when the differential upgrade is performed, backing up the source data blocks of the system partition to the cache partition; When the power is restarted, the unbacked source data blocks in the system partition are backed up to the cache partition; when the backup is completed, the backup files that are not configured with a unique identifier in the cache partition are released, and the differential upgrade is continued. The present invention generates a unique identifier through the backup file of the unbacked source data block during the differential upgrade process, and re-verifies the source data block in the system partition when an abnormal power failure is restarted during the upgrade process, and releases the verification process when the backup is completed The backup file saved in the cache partition in , and the file uniquely identified by the configuration is reserved. In this way, the backup files saved during the verification process are deleted, reducing the occupation of the cache partition cache, and the backup files required for the differential upgrade are retained, ensuring the need to continue the upgrade after a power failure.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, and in particular to a differential upgrade method for a mobile terminal, a storage medium and a mobile terminal. Background technique [0002] Android mobile phones are upgraded through a differential upgrade (Block-ota) method. Block-ota is upgraded by making a difference to the source data blocks of the system partition of the mobile phone, and moving or filling new data blocks. Before starting to modify the data blocks, it is necessary to save the backup of the source data blocks on the system partition to the cache partition, so as to prevent the mobile phone from being accidentally powered off during the upgrade process (for example, when the battery is pulled out), resulting in only partial data blocks on the system partition. Inconsistencies in the upgrade, and the upgrade cannot be continued after the power is turned on again. [0003] However, in the existing dif...
