I wonder which firmware update you've run and from where you've got it, because I can see
none here.

Probably you've tried to run the firmware update from

Torisan DRD-U424 OEM. The 1.32 firmware is RPC-2.
An utility is now available to reset the drive region code.

Check the current firmware of the drive to see which of the links/firmwares is the right one for your drive!
