Why must the device be connected to the Internet during Activation/ Deactivation?

The device must be connected to the Internet during Activation and Deactivation because it needs to communicate with the G&R license server. During the Activation process Glink sends the Glink Device Identification to the license server and gets a license file for this device id back from the server. During the Deactivation process Glink sends the Glink Device Identification to the license server and request a release of the license registered for this device id.

​

For the communication with the G&R license server, Glink uses secure and encrypted https-protocol and the G&R license server certifcate is validated by the device. This means that the device must have full access to the Internet to allow the certificate issuer (Thawte/Digicert) to be validated.

​

The Glink Device id is calculated from the Android device id, so you must keep in mind that the Android device id changes if/when you factory reset/rebuild the device. That means that you must deactivate your current license BEFORE you do a reset/rebuild to be able to release your license and that you must reactivate to download a new license file after a reset/rebuild of your device. If you forget to deactivate your license before you reset the device and reactivate, you will end up consuming two licenses for your device. If all your licenses are in use, your reactivation will fail. In this case you must contact your provider of Glink and request a license release. This will also be the case if you have a hardware failure and are not able to deactivate the license from Glink.
