Long story short;

I went to do a full reflash with a new DSP5 tune and it got into a "Retrying Previous Block" loop. I let it go about a dozen times then hit stop. Then no ECM response so keyed off. Got ECM response but getting a bootloader error after updating software. Old software says
"ECM in an unknown state"
Disconnecting
CAN-VPW Bridge deactivated
Disconnected
Data Transfer was interrupted
Done!
