Hmm, it looks like it doesn't like your loader.
Just check if your loader is actually 660,620 bytes and MD5 1e7c8fbadbab7127b8982bbcd344f646
A petty point, but I updated the edl.exe and you can download a version that is 131,584 bytes (just uploaded).
It really should have said:
Code:
Sending lumiloader.bin 100% Ok
Waiting for Firehose... No response, poking...
Could not write device
But that's just esthetics, it's not the problem.
Try:
Code:
C:\>edl.exe /llumiloader.bin /v
