Hi,
I had the same thing...
Remember when you upload to check if the firmware starts with the required magic number, this can be done using a Hex editor cut all the data up until the hex value of:

27 05 19 56

and thats it it should work ;)

BTW, which image are you trying to upload? I managed to use the ECB-9750 (9500) it boots up fine but only gives limited support Razz
I would love to start an organized disc. about this model Smile
