Force firmware update via CC on sb5101

Hi,

I am wondering if anyone knows how to force a firmware update from CC onto a sb5101 running hax rev39. I have unchecked disable firmware updates. I can see it trying to pull the update but it doesnt, I have added some of the log on that at end of the post. Now I have tried to extract the certs from downloaded configs but windows doesnt seems to want to open it, I tried changing the extensions between the various cert formats, no go.

If I can get the modem to accept the upgrade and pull the new certs from it, then flash hax back to it and inject the new certs, it should hopefully solve my problem. Anyone have any ideas?

Thanks.
