Help with C2D

Hi, hope someone can give me a hand with this... I got a ps3 with a broken drive, so I flashed it with rebug 4.21
I already extracted the EID_ROOT_KEY and NANDFLASH of my console, but cant get to work that last step to create de cex 2 dex file.

Can someone give me a hand with this? I would really apreciate it :joyous:

Thanks for everything
