I attemped to read my dme using JM garage flasher. I was not successful in getting the dme into boot mode. I re installed dme and found no communication and a no crank no start. Did i inadvertently wipe the processor? Any help would be great

Sent file. If you got.
How is you COM configuration.
Which cable you are running?
Any connection to ecu anymore?
If you don't have, send PN with VIN and all Informations of ECU you got (ecu label picture).
You also have to read ews to get ISN to get ecu paired. Or we will do immo off but this sucks a bit because of its automatic.
After pairing you can do Coding via WinKfp if needen. We also can do it remotly via TeamViewer.

Also write something about you knowledge and hardware you got.
Worst case need desolder or sent ecu and ews.
