Hello Tim,
I would recommend making sure that the phone has been factory reset and then trying to provision the phone again. Pay careful attention that when you enter the MAC address in the Hardware ID section that you only enter the alphanumeric characters, and that you omit the colons.
If you are still experiencing an issues, you will need to gather the logs from the phone and reach out to Customer Care.
