The method includes identifying a missing block of a plurality of blocks to be updated in the first memory, the missing block corresponding to a block being updated when the interruption occurred, copying a backup block into a backup buffer, simulating an application of the FOTA update in a second memory, the simulation including, for each block of the plurality of blocks to be updated, performing a reversible operation on the contents of the backup buffer and an updated block, and updating the backup buffer with the operation result, replacing the missing block with the updated backup buffer, and resuming the FOTA update.

Abstract: Methods, apparatuses, and computer program products for generating an update package based on a comparison between a base data image and a new data image, the update package including a set of instructions used for, in a remote client device, creating the new data image from the base data image, and for creating the new data image from the base data image based on the instructions included in the update package are provided.
