Backup Partition Strategy for Factory Reset Application Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The factory data reset function in electronic devices can inadvertently remove applications installed by the manufacturer, preventing them from being delivered to consumers.
Innovation Solution
An electronic device with a user interface, memory, and processor that includes a backup file for applications, allowing the device to move the backup file to a second partition not affected by the factory data reset, and then reinstall the applications from the backup file after the reset.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If factory data reset function is performed to initialize device state, then data and applications are cleared to factory defaults, but manufacturer-installed applications are inadvertently removed and cannot be delivered to consumers
Solution Approach 1:
The patent divides the storage space into multiple partitions: a first partition for user data and applications, and a second partition for backup files. The backup file is stored in the second partition which is separate from the first partition that gets formatted during factory data reset. This segmentation allows the backup to be preserved while the main data is cleared.
Solution Approach 2:
Before the factory data reset is executed, the system creates a backup file of the manufacturer-installed applications and stores it in the second partition. This preliminary backup action ensures that the applications can be restored after the reset, preventing their permanent loss.
2Ease of operation
If factory data reset function formats the first partition to clear data, then device is prepared for new user, but applications installed by manufacturer are removed
Solution Approach 1:
The patent extracts the backup file from the first partition and places it in the second partition before formatting the first partition. This extraction ensures that the backup file is not affected by the formatting operation, allowing it to be used for restoration later.
Solution Approach 2:
The second partition acts as an intermediary storage space that protects the backup file from being deleted during the factory data reset. It serves as a safe zone where the backup can be stored independently of the first partition's formatting operation.
3Quantity of substance
If backup file is stored in the same partition as applications, then storage space is utilized efficiently, but backup is deleted during factory data reset
Solution Approach 1:
The patent segments the storage into two distinct partitions: the first partition for active applications and user data, and the second partition for backup files. This segmentation ensures that the backup file remains in the second partition even when the first partition is formatted, preserving the backup's reliability.
Data Source
AI summary
In electronic devices according to various embodiments, after a partition in which one or more applications are installed is reset by a factory data reset function, the one or more applications installed in the partition can be installed on the basis of a backup file. When the factory data reset function is not requested by a user who has purchased an electronic device, for example, when an inspector of the electronic device requests the factory data reset function or the factory data reset function is requested on the basis of the SIM card that was first inserted into the electronic device, the restoration of the one or more applications using the backup file can be performed by the electronic device.
