[0017] Figure 1 This is a schematic diagram of an over-the-air (OTA) image file of the method for upgrading firmware in recovery mode according to an embodiment of the present invention.

[0018] Partitions running on Double Data Rate (DDR) memory or not used during operation are classified as Category 1 partitions, while other partitions are classified as Category 2 partitions. When an OTA upgrade is triggered, the received header (arrow ①) indicates which partitions are Category 1 and their corresponding data. After receiving data from the Category 1 partitions (arrow ②), the Category 1 partitions are upgraded. After a successful upgrade, the image of the Category 1 partitions is deleted, and then data from the Category 2 partitions is received. After completion, the system reboots into normal recovery mode for the upgrade.

[0019] Figure 2 This is a flowchart illustrating the steps of a method for upgrading firmware in recovery mode according to an embodiment of the present invention, applied to an electronic device, specifically a mobile terminal device.
