Thanks jcespi2005 for taking the time to help!!!
Everytime I think I understand it, it turns out I don't... :-s
I managed to dump Part00.raw, Part01.raw, Part02.raw and Part03.raw from my device.
Just to be sure, from what I understand, is that the ROM is inside the package called "RUU_Signed.nbh". But the ROM is also inside the .raw files.
And I need to extract the .raw files to get the .nbh file. Right?
So I am confused... because when I use the "Raphael_ROM_Kitchen_v0.62", I need sombody elses "RUU_Signed.nbh" file in order to extract the ROM from my own device.
