Abstract
When performing full firmware update procedure on an electronic device, a full firmware update file is divided into multiple pieces of update data and then arranged into a first and a second sub update files, a header file associated with the sizes of each sub update file is created, and the header file and the two sub update files are merged into a full FOTA file before being uploaded to the electronic device. The electronic device extracts each sub update file based on the header file and stores the extracted first and second sub update file respectively into a first and a second storage units. After performing the firmware update steps associated with the first sub update file, the second sub update file stored in the second storage unit is copied to the first storage unit before performing the firmware update steps associated with the second sub update file.
