After upgrading an OS7030 from original fimrware to 4.30k to get CLI on analog trunks system no longer boots - mem light flickers whilst loading but run light stays solid.

I've hooked up a serial connection, likely relevant sections of console output are:

The distributor's support site I have access to doesn't have any notes on what to do after a failed upgrade, can anyone help ???

Just sent you a PM hopefully that will help.

theres a way to default the 7030 to default on rocom website but unable to download it will try later if you need it

Thanks guys, system running again.

Problem arose from making such a major change of versions in one go.

Is that you Adrian? From P4L?
