SD-M1712 still locked after J004 AND X004?

Did I do something wrong? Using DISC Info 1.5.5 on my Toshiba SD-M1712 it says:

Drive region status: Lock Detected
Region setting status Not Set
User changes left: n/a
Manufactor resets left: n/a
Current region set: n/a

I used both firmwares J004 then X004. However I’ve been able to unlock 2 other dvd drives, a dvdrom and burner. For these drives (Toshiba SD-M1612 revB & Pacific Digital Mach-8 U-30213 aka NEC ND-2500A) it reads:

Drive region status: No Lock Detected

Have you played a DVD in the drive? You should play a DVD to set the drive’s region before applying a patched firmware.

I don’t know if that’ll work but I guess I’ll try reverting back to the original 1004 firmware, playing a pressed dvd, then reflashing it back to the “unlocked” firmware. Now the search for the original firmware and flasher…
