Unfortunately, at this point there is little that we can do. The fix, if possible, would require direct connection to the hardware. With our camera bodies not powering up, we have no way to interact with the hardware. Thus, our cameras will have to be fixed at Canon. They will take the easiest method of repair, which is to replace the entire motherboard, rather than to try to do a direct firmware burn onto the appropriate chips. P.S. I worked with real-time software in the defense industry. All of our work was with weapon systems. As you might surmise, our testing had to be extremely thorough. System failures like this could cost the lives of our soldiers. Obviously, the commercial industry has a lower standard of performance risk.
