How to build a retail image if you only have your RGH image.


PLEASE NOTE XEBUILD & DASHLAUNCH HAS BEEN UPDATED SINCE TUT WAS MADE. TREAT AS IF BOTH WERE UP TO DATE.

what you need for this is.

Your RGH image.
Your CPUKEY.
A clean SMC file. ( Clean SMC pack here)
And the right LDV.

NOTE


If your unsure of the LDV,then wire up the xbox to your router using a ethernet cable.and boot to xell,wait for it to fully load on screen,and put the ip addy into the ip box in j-runner,load your rgh image into source,and press the get cpukey button.it should load the correct LDV then..






First thing you need to do is read the RGH image from your nand.
Once you have read the nand,take note of the LDV.And the CB version.



The next thing you need to do is extract the required files needed from your RGH image.

So click on tools,then click extract files.





Now that you have extracted the files needed.

Go to the output folder in J-Runner.And you will see a folder named Extracts-(console serial number).
You want 3 files from this folder,KV_dec/fcrt_dec and smc_config..



Rename the KV_dec file to KV,and rename the fcrt_dec to fcrt.



Next you want to go to J-Runner\xeBuild\data folder.



Now you got the right folder open,you need to place the renamed files into this folder.the KV/fcrt and the smc_config files go in here.

You will also need to place the clean SMC file in here aswell.



Now you have all the files in the right place,you are ready to create your new retail nand.

So restart J-Runner.and enter your CPUKEY as it shows.

Make sure the retail is ticked.and select the dash version you want to build your image as.

Next click on advance,and go down to create an image without a nanddump.bin





To determine which LDV value is required to build your retail nand look here

You can download the X360 CPU Fuse Calculator from here (thanks to BL4K3Y)

Now you should get xeBuild options pop up.enter your LDV and press ok.



Now you should get another pop up.select your mobo type.and press ok.



Now just wait for J-Runner to do it's magic.



Once J-Runner has done it's stuff.press the Re-Init button and your image will load and you'll see it has the right LDV.and is ready to write to your xbox..





To determine which dash to use, please look at info below (with thanks to 15432)

Code:
Until yesterday, ALL RGH images used old CBB. So you can't use that info to recognize what dash you need.

So.. I recommend to dump your e-fuses using XeLL and check the second fuse
I have pretty good table with all possible values, but it's not in English. So I'll post the most common ideas:

Fuse 02 looks like F0[B]F[/B]0000000000000...
The most important thing there is last F's number. In my example, last F is placed in 3rd position. 

So the idea is you can determine the dash needed depends on that positon!

Phat: 
[I]pos <= 5[/I]       ---> 7371 and below
[I]5 < pos <= 7[/I]  ---> 8498 - 14699
[I]7 < pos <= 10[/I] ---> 14717 - 14719
[I]10 < pos[/I]         ---> 15772 and above

Slim:
[I]pos <= 2[/I]      ---> 14699 and below
[I]2 < pos <= 3[/I] ---> 14717 - 14719
[I]3 < pos[/I]         ---> 15772 and above



Tip

TIP


Here's my tip if your CB VERSION happens to fall on Dash 15574 or above,then build your image that is one version below the latest dash out..that way you can do the update,and get fresh retail dumps of the nand..

You should read my reply to the original thread. Same fail. RGH images can use old CB (13121), so you can't determine the dash version needed using CB! You must check fuseset #02

15772 never existed .. 15572 is what it should be :)
