Tutorial:
The Simpler Way to Change a Keyvault Via Flash360
By: Xbox360Xperts (Lskywalker332)

For those of you who like my previous tutorial on how to update via USB, I have updated the tutorial to use Flash360 rather than Xell to dump and write your NAND as some people were experiencing problems getting their USB drive to be recognized by Xellous.

If you have any questions you can IM me at AIM: xbox360xperts or Skype: xbox360xperts



This tutorial will give you a step by step on how to change the keyvault on your Xbox 360 using Flash360.


How to change the keyvault via USB using Flash360:

What’s needed:
•360 Flash Tool v0.91 ( [ Register or Signin to view external links. ] )
• Xbins Auto Launcher ( [ Register or Signin to view external links. ] )
•Flash360 (available at Xbins)

•Nand dump and CPU key from unbanned Xbox 360
or
•Decrypted keyvault from unbanned Xbox 360


Lets get started.
Extracting unbanned Keyvault from clean Nand. You MUST have the CPU key in order to extract and decrypt the keyvault from the Nand (if you already have a decrypted keyvault (kv_dec.bin) then you can skip down to step 18.

1. Open 360 Flash Tool and click the “Keys” menu.
[ Register or Signin to view external links. ]

2. The keys menu will open up and you should enter the CPU key that goes with the unbanned Xbox 360 nand file. (see picture below) Without the CPU key for you nand you CAN NOT decrypt/extract the keyvault. If you did not receive the CPU key from the person you bought it from you need to get it from them.

3. Click the “Open File” button.

4. Select the nand file that you purchased (for this example my file is named “nand_oirg.bin”) If you have the correct CPU key that corresponds with the nand file you opened the serial, DVD, OSIG and other menus will show the information of the Xbox 360 the nand was extracted from.

If the CPU key is missing, or is not the right key then flash tool will say “Bad Key/KV” (see the picture below)

5. If you’ve got the right CPU key and 360 flash tool is showing the correct information click on the “extract” button.

6. Check the box next to “key Vault” and click “OK”

7. You will be prompted to choose a directory to save the new files to. For this example I have used the directory “XBOX_360” on the root of my “C” drive.
[ Register or Signin to view external links. ]

You should now have 3 new files in the directory you pointed to names “kv_dec.bin”, “kv_enc.bin”, and “log.txt”

Next I will show you how to recover your NAND from your Xbox 360 console. If you already have this file saved locally on your computer you should COPY (not move) it to the same directory as the other files now and skip to step 18.
 

8. Download and launch xbins and download Flash360v1.0.zip. I have highlighted the path to find it.

9. Open the Flash360v1.0.zip file and extract the files to a new folder called “Flash360”.
[ Register or Signin to view external links. ]

10. Copy the Flash360 folder to a USB Flash drive and plug it into your JTAG’d Xbox 360.
[ Register or Signin to view external links. ]
 
11. On your Xbox Launch XeXMenu form the Games tab. If you do not already have XeXMenu installed then check out our tutorial section as there is a step-by-step to install it on your xbox.

12. You will be asked to sign in to a profile so just pick one. Once launched you’ll be faced with the XeXMenu main screen.
[ Register or Signin to view external links. ]

13. Hit the right bumber (RB) once and you will be able to browse for files on your xbox 360 storage devices. If you have a HDD plugged in then it will likely be the first to show up. Use the D-pad to switch to your USB Drive directory (the one containing the Flash360 folder).

14. Scroll to the Flash360 folder and press “A” to open the directory. Then scroll to “flash360.xex” and press “A” to launch the program.
[ Register or Signin to view external links. ]

15. You will be faced with a blue screen similar to below. Press “X” to backup your current NAND to the USB Drive.

16. Press the “A” button to save entire NAND to file.
[ Register or Signin to view external links. ]

17. The program will execute and start backing up your NAND.
[ Register or Signin to view external links. ]

Once the process has completed there will be a new file in the “Flash360” directory of your USB Thumb drive.


18. If you do not know your CPU Key for your xbox retrieve it now by booting the xbox with the eject button. Make sure to leave theDVD tray open while the xbox starts up which will cause the xbox to boot into Xell/Xellous. When the process is complete you will be presented with a screen similar to below. Your CPU key will be in the red box (the picture below has it ereased)

19. Reopen 360 Flash Tool and click the “Keys” menu.

20. Enter the CPU key that corresponds with your Xbox (the one we just got from Xell/Xellous)
[ Register or Signin to view external links. ]

21. Reopen 360 Flash Tool and click “open File.”
[ Register or Signin to view external links. ]

22. Plug in your USB Flash drive and browse to the folder “Flash360”. Within that folder there is a file called “flashdmp.bin” that we just created. Select the file and click open. (note for this example the file is named “my_xbr_nand.bin.”) If you entered the CPU key correctly you should see the DVD key and serial number of your banned console.

23. Click the “Import” button.

26. Click the “OK” button.
[ Register or Signin to view external links. ]

27. You will be prompted to save the new file. Browse to the same directory we have been using and save the file. For this I saved my file as “my_xbr_nand_unbanned.bin.”
[ Register or Signin to view external links. ]

28. You will be dumped back to the main screen of 360 Flash Tool and everything will look as it did before importing the keyvault file. Click the “Open” file and select the file that we just saved in the previous step. If everything was done correctly then you should get a screen that shows all of the information from the unbanned console, but saved to the nand file for your console.

We are now ready to update your xbox 360 console with the new unbanned nand file.
 
29. Make a copy of the newly patched nand file we just created and rename the new file “updflash.bin”
[ Register or Signin to view external links. ]

30. Copy the “updflash.bin” file to a USB drive in the directory “Flash360”. Once completed plug your USB drive into your xbox 360 and power up.
Note: is it VERY important that you make sure your updated NAND file is correct for the Xbox. If it is not you will update your console and not be able to boot. The only way to recover from a bad update is to flash the Xbox via LPT or USB adapter.

31. On your Xbox Launch XeXMenu form the Games tab. If you do not already have XeXMenu installed then check out our tutorial section as there is a step-by-step to install it on your Xbox.

32. You will be asked to sign in to a profile so just pick one. Once launched you’ll be faced with the XeXMenu main screen.

33. Hit the right bumper (RB) once and you will be able to browse for files on your Xbox 360 storage devices. If you have a HDD plugged in then it will likely be the first to show up. Use the D-pad to switch to your USB Drive directory (the one containing the Flash360 folder).

 
34. Scroll to the Flash360 folder and press “A” to open the directory. Then scroll to “flash360.xex” and press “A” to launch the program.

35. You will be faced with a blue screen similar to below with (2) options.
[ Register or Signin to view external links. ]

36. Press “A” to continue to the write menu.
[ Register or Signin to view external links. ]

By pressing button “A” you will write your new NAND leaving your current keyvault and config files in tact on the Xbox NAND. This option would be used if you are updating XBR, Freeboot, etc and want to leave console specific information intact (not change the kv)

By pressing button “B” you will overwrite the entire NAND on your Xbox with the new file that is on your USB thumb drive. This would be for if you were trying to change your keyvault to unban your console.

37.For this example I will be changing the keyvault on the NAND so I press the “B” button. Because the keyvault on the update does not match the keyvault on your Xbox you will be faced with a warning similar to below. This is normal because we are changing the keyvault.

38. If everything is correct and you are absolutely certain that you are using the correct NAND we created press the “Start” button to start the flashing process. The program will give you status while it flashes and once complete will say press any button to continue and then press the back button to shutdown.

39. Restart the Xbox and enjoy your updated NAND. If you did everything correctly your system will now boot up and you will have a fresh keyvault installed.

Note: If you get an e79 error there is a very good chance that the file you thought was the nand for your console was not correct or you installed the nand you bought to your console instead of your own nand. In either case you will need to reflash your console via LPT/USB.

Say Thanks if you use this.....
