Yes, I tried both .fir files and none of them made any log or bin file...
I've made more test with the second autoexec.bin:
The camera starts, during the sensor cleaning the ML text shows for a very short time then disappears.
The camera works until I fully press the shutter button -> ERR80 (remove battery helps only)
If I press the menu button -> menu shows and ML text on the top of the menu (see the screenshots), the LCD freezes (menu, info, play, pict modes, func not responds) but the front and rear wheel, the WB, AF, ISO, half shutter buttons work.
If I press the play it shows the last picture and the ML texts and same happens when the menu button press. Same happens with Function, Picture Style, Info: once a display shows something then the LCD freezes.
If I change a mode (like Av to Tv) the camera freezes temporarily but after the metering timer finish then works again.
