After
restoring my Hitachi to the original FW-state I had a crazy thought of building an external DVD-drive to use with my other 360. My idea is to enclose the Hitachi drive in an external USB-casing so I can easily hook it ip to either my PC (USB) or my 360 (SATA). In case you're wondering how I would hook this up to my 360 without having to open it all the time read my earlier posting about the
SATA-extension I made.
However as you possibly know you can't just use the DVD-drive from one 360 in another 360 because each 360 drives firmware has it's own unique 16-bytes key embedded. So to get the Hitachi-drive running on another machine I had to do at least the following:
- Dump the unique 16-byte key from my other 360's Samung-drive;
- Flash the Hitachi with the obtained key from the Samsung.
Step 1 - Getting the key from the Samsung-drive
I used my earlier build bootable USB stick to boot my PC using DOS. I then used mtkflash to dump the FW of my Samsung-drive:
mtkflash r /m samsung.bin
After rebooting my PC to windows I used
Keydrive Xtractor 1.5 to grab the 16-byte key from the FW like this:
Please Note: DVD Key shown is fake dataStep 2 - Preparing the FW-bin from the Hitachi
After copying the DVD-Key to the clipboard I opened the original FW from my Hitachi (orig.bin) and pasted the DVD-Key from the clipboard to the DVD-Key field. I then saved the firmware as "hits.bin".
As you probably know by now the Hitachi-FW has to be encrypted before flashing. Using a tool made by Loser named
FirmCrypt I created a "ready to flash FW" using the following command:
firmcrypt e hits.bin hitse.bin
So there it is: the encrypted firmware hitse.bin ready to get flashed.
Step 3 - Flashing the Hitachi with the new key
After putting my Hitachi drive in ModeB using the
SlaxVM solution I flashed the sector containing the drives key from windows XP (i being the drive-letter):
flashsec47_win i hitse.bin 90004000 1000
Please note there's no need to flash the Master Checksum since the key is in an area of the FW not included in the checksum-calculation.
Step 4 - Attach the Hitachi to the new 360
After plugging in the power and the sata-cable (which leads to the motherboard of the new 360) and inserting COD2 it was time to fire up the new 360. And as expected: it works like a charm :)
So there it is: My Hitachi drive works in a 360 it wasn't "married" to before. At least this part won't stop me from building my external DVD-drive! Still not sure if I go through with it.
