A method for updating code stored in a memory of a portable device, such as a mobile phone or PDA, includes providing a plurality of code modules each having at least a target image reference (TIR) tag that uniquely identifies operational subunits of the code module, and providing a target image of operational code in the memory of the target device. The target image includes subunits and appended TIR tags uniquely identifying the subunits. The method further includes locating the TIR tag in the target image corresponding to an updated subunit to be loaded in the image, and loading the updated subunit into the memory of the target device at the location determined. The TIR tags allow for only updated subunits to be loaded into the memory of the device, reducing time and processing required and further reducing susceptibility to errors.
