sb5101, good certs/mac, but CVC Validation Failure?

[unknown]

Ok just got home and yea my modems are sb5101 so sb5100 is not the problem.

There is a problem my friend. If you are using a sb5101 nonvol on a sb5100, it will not work for its not compatible . but if you are using a sb5100 and extract each individual cert and load it to sb5101 it will 100% will work if the conversion was done right. So you need another sb5101 modem for that
sb5101 provision nonvol.
