After trying to create a Knox container with an EMM policy, the error message "invalid licence key" is displayed.
This might be because your device does not have official firmware. A device with non-official firmware sends the Knox license activation request to an internal Knox license server instead of the external license server. Since the license key given to external customers is valid only on the external server, the license activation request fails.
NOTE – If you are using your device for testing purposes, for example, to verify that an app works in a Knox container before releasing the app to the public, you should get a test license rather than a production license.
Q: What is official firmware?
This is the firmware that is installed on a mobile device when it is shipped from the factory or sold by a mobile carrier. Official firmware can be updated OTA by the device vendor or carrier.
Non-official or custom firmware (also known as a custom binary or ROM) contains modified system files. These types of firmware might have been installed for testing purposes or to root a device. Note that if your device has these types of firmware, you might encounter problems installing a secure Knox container or activating a Knox license.
Q: How can I check if my device has official firmware?
- Get your device log.
- In the log file, search for ro.product_ship.
