Claim 7:
8. A motor vehicle comprising a device, the device comprising: a controller, and a processor device, wherein the device is configured to perform operations comprising:
receiving, at the processor device, a program code packet via a first data connection from a device-external data source;
building, at the processor device, a checksum value in response to the program code packet;
receiving, at the controller, a reference checksum value from a device-external update server device via a second data connection that is different from the first data connection, and the checksum value built by the processor device;
determining, by the controller, whether the program code packet is installed on the processor device;
initiating, by the controller, an installation procedure for installing the program code packet on the processor device upon determining, by the controller, that the checksum value and the reference checksum value are identical and the program code packet is not installed on the processor device; and
performing, by the controller, a reset of the processor device from outside the processor device after a specified period of time by interrupting an energy supply providing electrical energy to the processor device.
