Additional Information:

NOTE: This upgrade tool will only flash the dongle once. (The softpaq tool can be executed without any changes or damage to the USB-C to RJ45 Adapter. If there is uncertainty that the USB-C to RJ45 Adapter has been flashed, just rerun the Upgrade Tool again.) Please mark the USB-C to RJ45 Adapter to keep track of upgraded adapters.

NOTE: This tool is not SCCM Compliant and will fail and will not complete the process.

Part of the Process when executing the Upgrade Tool is resetting the USB-C to RJ45 Adapter which happens when the adapter is unplugged, upgrading another USB-C to RJ45 Adapter, and then repeating the process.

This would cause the Upgrade Tool to fail and the network connection to drop, causing the deployment to also fail if the SCCM TS is used to deploy this process.
