Abstract: This application relates to a profile transfer method, and an apparatus. A first electronic device includes M profiles of eSIM modules, and determines at least one to-be-transferred profile in response to an operation command for a first transfer interface, where the first transfer interface is used to display transfer of the M profiles; the first electronic device sends a first message to a second electronic device, where the first message includes at least one piece of transfer information, and the transfer information includes at least one of the following: an identifier of a to-be-transferred profile, an address of a profile server corresponding to the to-be-transferred profile, or an identifier of the second electronic device; and the first electronic device displays, in the first transfer interface, that transfer preparation for the at least one to-be-transferred profile on the first electronic device is completed.

Abstract: A patch generator for generating a patch that expresses a series of updates to a source image that will transform the source image into a target image. The patch generator compares sections of the target image, in turn, with respective versions of the source image. The patch generator generates the series of updates for the patch in dependence on the comparisons between the sections of the target image and the respective versions of the source image. Comparing each section of the target image with versions of the source image that are expected to be stored by the device during the process of implementing the patch allows the possibility that the device could change the source image in its memory while it implements the patch.
