Add me to the list of people with a console that will only play backups.
I know it's not the laser, I just replaced it with a brand spanking new one I had to remove the solder off of it myself. In my case I think it's the firmware being corrupt.
It was originally a Hitachi 46 running Ix1.5 I bricked it restoring it. So I spoofed a blank Sammy with the CFW from the hitachi46 (Don't have the original

) into a ix-151 stock blank bin from the jf library. It flashed without any errors, (kept getting random error counts in DosFlash32?) And wullah! I now have a console that will only play backups, I'm scared to take it online since it can't read my originals, and I fear if the bin is corrupted M$ may be able to detect it.
Any pro's got any ideas, on how we can fix our consoles?
