This scenario describes how the OMA DM v1.2 server would send a secure update for a Shell ROM package to the device. The following steps describe the process of updating a device by using a single ROM package. A file that contains a single update package has the .pkg extension.

  1. The OMA DM v1.2 server sends an SMS trigger to start a DM session.

  2. The device connects to the server.

  3. The server creates a Firmware update object, and then sends the Exec command to the device.

  4. The FwUpdate Configuration Service Provider accepts the command, and then calls the Download Agent to download the package.

  5. Once downloaded, the Download Agent directs the OS to install the package.

  6. When the installation is complete, the Download Agent obtains the installation results from the registry.

  7. The OMA DM client connects to the OMA DM server and then sends the installation result to the server over package #1 by using the generic alert element. For information about generic alerts, see OMA DM Generic Alert.

  8. The DM client notifies the Download Agent the DM session result. For specific result codes, see OTA Firmware Update Result Codes.
