Recooking dumped ROM

[vogonj]

Hello,

before I flash my Diamond with a ROM by the chefs or maybe a ROM made by myself I want to backup the original ROM (T-Mobile GER) for warranty reasons. T-Mobile Germany isn't providing any ROM updates yet, so I have to build my own T-Mobile stock ROM.

I already dumped the ROM after making a hard-reset to bring everything back to factory defaults:
D:\ROMdump>pdocread -l
210.13M (0xd220000) DSK1:
| 3.12M (0x31f000) Part00
| 4.38M (0x460000) Part01
| 111.50M (0x6f80000) Part02
| 91.13M (0x5b20000) Part03
3.75G (0xf0000000) DSK7:

Now cooking a dumped ROM requires following files:
RUU_signed.nbh
Part01.raw
Part02.raw

My question is: What is the RUU_signed.nbh file I need in this case?
I guess it has to be the Provider Stock-SPL. If so, can I use the dumped SPLdumped.nb (after converting it to nbh)?
And will the ROM be all original then? Original in a way that I even don't have to Hard-SPL my device to flash it with that dumped and recooked ROM?

I found this little piece of information nowhere, so thank you for your help :)

Hello again,

as there is no stock ROM, stock SPL, stock whatsoever for my MDA Compact IV from T-Online Germany, I have to build my own stock ROM.
T-Mobile Germany has absolutely nothing in stock. And I don't expect anything within the next year:( I don't know why they don't care for their customers :confused:

That's why I need your help.

I already dumped the ROM and SPL and got these files:
Part01.raw
Part02.raw
Part03.raw
Part04.raw
SPLdumped.nb

Building a ROM from dump requires the following files:
RUU_signed.nbh
Part01.raw
Part02.raw

Question:
What has to be the content of the RUU_signed.nbh file? Is it the SPL?
If so, can I use the SPLdumped.nb from my dump (after converting to .nbh, of course)? Will the result be a stock ROM then?

Assume that the device is all original out of the box, nothing flashed so far.

Thanks for your help :)
