Abstract
A system includes a processor configured to detect a vehicle key-off. The processor is also configured to delete from a primary memory (“internal memory”) of an electronic control unit an existing software version for which a new software version update exists in a secondary memory of the ECU. The processor is further configured to load the new software version from the secondary memory (“external memory”) into the primary memory and upon detection of a failure during the load, delete the new software version from the primary memory and reload the existing software version from the secondary memory.
