Morphine packs all data file inside ".text" section. Try to find this file data inside ".text" section after passing second decrypting loop and find original PE header, then create your custom PE header according to its.

Yes Vodu,
i just resolved in way that you have explained.

To find this "original" value, i track the sections table information in Olly using the VirtualAlloc/return bp.
Then with the original values i have fixed the right RawOffset/Rawsize VirtualOffset/VirtualSize.

Thanks a lot for your advice too.
