D710a Operating Panel Firmware Update

Ryan - K9NBG

I just got a Kenwood D710a that had firmware 2.10 installed, figured I would go ahead and update it since the MCP software was complaining.
Firmware updated fine, did a full reset, but when i try to update the panel I get an error 'Could not detect the operating panel'
I've tried to reset the VFO and full memory, reboot computer, different com speeds, each time I can't update the panel firmware. Anyone else seen that or have any ideas?
