Data flow: Updating firmware on
Samsung Knox
 devices

This data flow describes how data travels when you use
Samsung
 Enterprise Firmware Over the Air to control when firmware updates from
Samsung
 are installed on devices. For more information, see Controlling the software releases that are installed on devices in the Administration content.
Diagram showing the steps and components mentioned in the following data flow.
  1. An administrator adds a
    Samsung
     E-FOTA customer ID and license key to
    BlackBerry UEM
    .
  2. The
    BlackBerry UEM Core
     sends the license information to the
    BlackBerry Infrastructure
     over a TLS connection.
  3. The
    BlackBerry Infrastructure
     establishes a TLS connection with the
    Samsung
     E-FOTA servers and provides the customer ID and license key.
  4. The E-FOTA server verifies the information and returns license information through the
    BlackBerry Infrastructure
     to
    BlackBerry UEM Core
    .
  5. An administrator creates a device SR requirements profile and specifies a
    Samsung
     device model, language, and wireless service provider for a new
    Samsung
     device firmware rule.
  6. The
    BlackBerry UEM Core
     connects to the E-FOTA server via the
    BlackBerry Infrastructure
     over a TLS connection and sends the specified criteria to the E-FOTA server.
  7. The E-FOTA server verifies the criteria and returns firmware information through the
    BlackBerry Infrastructure
     to
    BlackBerry UEM Core
    .
  8. The administrator saves the new device SR requirements profile.
  9. The
    BlackBerry UEM Core
     connects to the E-FOTA server via the
    BlackBerry Infrastructure
     over a TLS connection and sends the profile to the
    Samsung
     Cloud.
  10. The administrator assigns the device SR requirements profile to one or more users.
  11. BlackBerry UEM
     sends the profile to the
    BlackBerry UEM Client
     on the user's
    Samsung
     device.
  12. The
    Samsung
     device registers with the E-FOTA server.
  13. If a firmware update is available that meets the parameters specified in the device SR requirements profile, the E-FOTA server sends the update to the device.
