You must be talking to becandcall - no way firmware was getting updated on mine without the model being properly set and until EEROM was cleared the machine was locked up in the startup. Only way to do it is to clear EEROM, install either a good ISS or electronics unit that is loaded from a machine with the same model number and tell it that the opposite was installed so it backs up the temp unit's EEROM to the normal unit of the machine. Mine was done and all is well and the new owner is chugging along with it fine.
