DCT4 change firmware version number!?

Hello guys
it's been long time I m searching for any hints/tips on how to edit a DCT 4 flash file.
I need to change the firmware version number that is displayed when dialing *#0000# without upgrading to another version.. which means, I need to put an MCU version that nokia didn't release :razz:

The mcu and ppm I'm using can be downloaded here;
numediaweb.free.fr/1100/rh18_03.440
numediaweb.free.fr/1100/rh18_03.44ic

I need to turn the phone into;
V 3.430
12-09-2002
RH-18

hope any help from you guys.

PS; I have Hex workshop, but can't figure out which adress to modify.
don't know if the firmware version resides on the MCU or PPM!?
