I updated my firmware on a pioneer a03 now it wont work at all. It says its good in device manager but it wont read or write to cds or dvds anymore. Tried reinstalling it, tried running the firmware again, it says already updated. If I try to access it with windows it freezes and I have to shut it down with task manager. If I try to burn with prazzi it says Disc Read Error-Command:51 Sense: 04 ASC: 08 ASCQ: 01 Cant find an older version of firmware to install and am not sure if you can even do that. Please help if you have any ideas.
