How to cable-unlock a 6101

[gh01]

Hi,
I have a 6101 that needs to be unlocked via cable (unfortunately I used the IMEI on the box instead of the actual IMEI of the phone to calculate unlock codes - sure, they SHOULD be the same...)
Anyway, I have a couple of cables here a CA-42 and a DKU-5. Both are supposedly F/MBUS, both are USB, but emulate a COM port.
Is there any software I can use to unlock the phone with either of these cables?

So far I have tried:
Nokia DCT4 Unlocker (Cyber) - reports success, but phone is still locked.
FBus by Maestro (0.25) - Most functions work (backlight, speaker test, test/local mode, etc), but the "Read" function does not fill the info correctly.

I have tried a few others without success. It seems that anything that expects an MBUS connection does not work at all.

Any suggestions would be greatly appreciated.

Thanks.
