Looking for a definative answer on decrypting/encrypting the firmware

[PS2MXBOX]

This is my goal...

Let's say I have a Hitachi drive in my xbox right now and a spare TS drive sitting on my desk. I would like to dump my Hitachi fw for safe keeping and to get the key out of it, then put that key into the xtreme flashed TS spare.  Now I can't get the Hitachi to dump as I have sis964 chipset, but thats not the point.  Let's pretend I dumped the Hitachi FW. Does It need decrypted before I can use KDX to get the key? Then do I save the key and put it in the xtreme_proper.bin and then does that need to be encrypted before flashing it to the TS drive I want to use in the end? Does any checksums need to be recalculated or anything?

Thanks, I tried searching but couldn't get a definative answer, and none of the TS hacking guides have anything about encrypting or anything along those lines.  Thanks all...

1) Yes hitachi firmware needs to be decrypted when using KDX
2) You need to use xtream_proper.bin to get the hitachi key in the right spot
3) No the TS has no encryption
4) No checksums in the key area.

Edit: Its pretty simple task, just dump your key from the hitachi firmware using KDX, get xtream_proper and use kdx to insert hitachi key and flash. Very simple

Oh can someone explain that the sytax is for firmcrypt as every time i enter d gdr.bin done.bin it starts yelling about < was unexpected at this time.  I can't get it to decrypt anything.  Thanks again

on a side note my old media pc w/ sis964 chipset running Media Center 2005 worked fine with the Hitachi drive, using crossed wires to force modeB.

Use seventhsons meathod
http://www.kev.nu/360/dvdshort.html#4
it will dump just your key ready to be put in xtream_proper with kdx

http://www.kev.nu/360/misc/memdump_win.zip
memdump_win e 91004F0 1 10 key.bin

Open key.bin in winhex or somthing and copy the key into KDX (copy hex values not text)

Okay but does this method of just the key lines of code need decrypted or not?  And what would a decrypted key look like as compared to an encyrpted one?

This meathod will dump the key decrypted and thats what you want when flashing it to a TS. When encrypted the key will be totaly different and will not work in the TS. The encryption is only needed when reflashing back to a hitachi. If you want to get a TS to work with the hitachi key it will need the decrypted key. Like seventhsons meathod gives you.

This is exaclly what I did.
memdump_win e 91004F0 1 10 key.bin
open that in winhex and copyed the hex values
opened xtream_proper.bin with KDX and pasted the hex values from key.bin into there and saved
then just flashed it to a TS and it worked perfectly

sounds good stonedsmurf...now if only i can find a sil chipsetted board somewhere. I'm a little hesitant to be grounding points out.

[stonersmurf]

one more thing the e in this syntex is the drive letter, so when you do it replace e with whatever your hitachi drive letter is in windows
memdump_win e 91004F0 1 10 key.bin

Im probably wrong but isnt there a simpler way? i used the crossed wire method to obtain my hitachi firmware, then KDX1.5 to obtain the key. Cant you then copy the key, open the Xtreme firmware, and paste the key in b4 saving and flashing?
