Wont boot after upgrade

I just completed the upgrade build from MK2s to MK2.5s.  When I turn on the machine to do the flash the firmware, I get this: 

I have let it sit for 20 minutes or so, but it doesn't go away.

Thoughts?  I am guessing one of the connectors is not fully seated on the Rambo, but I can't find it.  They all seem to be in right.  Which should I be focussing on?

thanks

RE: Wont boot after upgrade

I had the same issue. Until I realised that I had picked the wrong HEX file while upgrading the firmware. The one I picked was for the rambo 1.0a instead of the 1.3a that is in my printer. That was my problem. Have you checked you chose the right HEX file?
