IndivisionECS v2 Amiga600 not working

Yes. The flashing tool on the rescue disk, does not work on my 600-setup.

Sorry... Need to add this...

The flashing tool works 100 percent on my 500. If i *brick" the IndivisionECS V2 on my 600, then I have to transfer it to my 500 and flash it on that, and then put it back in my 600.
