You could also do this if you have your original.bin from your hitachi:
1) Dump firmware as you stated.
2) Use samtool with your dumped fw and Xtreme 5.2(A-D) of your choice:
samtool orig.bin xtrem52A.bin
This will copy the entire $4000-5FFF range over.
If you get prompted to copy the version from the original to the hacked firmware, it doesnt matter, you will overwrite them in the next step anyways.
3) Then, with xtreme52A.bin and your original hitachi firmware, use samtool again:
samtool original.bin xtreme52A.bin
This should copy the key from the hitachi and put it at the last key location of your orig.bin (overwriting the key). Then it will prompt you to copy the version strings like the tutorial. Double check with a hex editor.
Then flash the Xtreme firmware.
