X1 box activation issue - error XRE-00251

I have an XG1v4-A box shipped by Comcast ~4 months ago that was never activated. It’s now showing error XRE-00251 and needs to be re-added to my account. The app and phone support only offer modem/router activation options with no TV box path. Need help getting this box re-provisioned.

No response from the forum. Still unsure on how to proceed. Was going to call Billing to determine if they can help with activation. If not, was going to call tech support. Appears to be a simple issue. Apparently did not activate within Xfinity window. Still have boxes.
