One of my 5100 radios crapped out in the middle of a firmware upgrade. Past experience has told me to quit the express uploader and then restart the program from scratch before attempting the process again.

This time, however, it came up with "Communication error while trying to retrieve boot version". I take that this is not good. Radio does not boot up, but goes into Bootload mode just fine.

So far, I've tried tricking the Express Uploader into writing by reading another radio's boot version and then swapping immediately to the sick radio. When this happens it restarts from scratch and finds the same error.

Any chance anyone else has gotten past this issue?
