Credit for this tut goes to leech.. And ********* approved!

Ok guys I tried to build my own image to see how easy it is and I was successful but I didn’t flash my 360 so please correct me if something is wrong here

(my only concern is that I obtained the smc.bin from Cygnos360 V2 SMC Collection.zip)

This was done on Vista 32-bit

Tools needed:

1) Auto Xbins : [ Register or Signin to view external links. ]
2) freeBOOT-0.031.zip from xbins : /XBOX 360/development/freeBOOT/
3) 9199.zip from xbins: /XBOX 360/development/freeBOOT/
4) Cygnos360 V2 SMC Collection.zip from xbins: /XBOX 360/development/Cygnos360/
5) libeay32.zip [ Register or Signin to view external links. ]
6) Your original nand image (**DOES NOT NEED TO BE 7371**)
7) Your CPU key

1. First things first open up freeBOOT-0.031.zip and extract it to your desktop

2. Open up the libeay32.zip and extract the libeay32.dll to the freeBOOT-0.031 folder:

3. Take your original nand dump and for the sake of the guide rename it to original.bin, after put that file original.bin into your freeboot-0.031 it should look like this:

4. Next you are going to go to your desktop, hold down shift and while holding shift down click open in command window here:

5. Now when your command window opens up it should look like this:

6. Now you are going to have to copy this line and paste it into the CMD window (just replace the CPUKEY line with your cpukey):

ibuild.exe x -d temp -p CPUKEY -b DD88AD0C9ED669E7B56794FB68563EFA original.bin and press enter.

This is what your window should look like the red is supposed to be your cpukey (I blocked out mine)

7. Now open up 9199.zip and put all the contents from the zip into the freeBOOT-0.031data folder

8. Now go to freeBOOT-0.031temp and take out these files from there and put them into the freeBOOT-0.031data folder

- crl.bin
- crl.bin.meta
- extended.bin
- extended.bin.meta
- kv.bin
- odd.bin
- odd.bin.meta
- secdata.bin
- secdata.bin.meta
- smc_config.bin

9. Now open up Cygnos360 V2 SMC Collection.zip and pick the file that’s associated for your console and extract it. After you extract it rename the file to smc.bin Now put the smc.bin file into the freeBOOT-0.031data folder

10. Now go to your CMD window and copy this line and paste it in and press enter:

ibuild.exe c freeBOOT -c CONSOLE -d data -p CPUKEY -b DD88AD0C9ED669E7B56794FB68563EFA binimage.bin binfuses.bin

- Replace CONSOLE with your console name one of these: xenon, zephyr, falcon, jasper, jasper256 or jasper512
- Once again replace CPUKEY with your cpukey

This is what it should look like (The red is my cpukey and as you can see my console is a falcon so I wrote falcon in there):

11. Your done now go to the freeboot-0.031bin folder and you should see image.bin, This is your newly built nand image now go and flash it the way you prefer.

**For flashing with XBR this should work (didnt test it): Take the image.bin that was created from the freeboot-0.031bin folder and rename it to updflash.bin Then put updflash.bin into a flash drive (USB Stick) Then run 360Flashtool from your 360 When in 360Flashtool press **Button A - Write updflash.bin to Nand** and thats it you should have a newly installed freeBOOT with 9199 kernal.

If You Get E79 Error try these solutions
1. PowerCycle - After flashing unplug the 360 for at least 1 minute
2. Make sure the date of the new freeBOOT image is the same as your original nand image


open your NAND in the hex editor you should see something like 2004-2007 or 2004-2005. Make the date in your final freeboot image matches the one from your 7371 dump. (edit the final freeboot image)

There is no need for a tutorial. kiddies can hex edit.

For example My 7371.bin is opened in HxD and at the top it says:

© 2004-2007 Microsoft Corporation. All rights reserved


and my image.bin says:

© 2004-2005 Microsoft Corporation. All rights reserved


i would change image.bin to say:

© 2004-2007 Microsoft Corporation. All rights reserved



Easy? yes! So easy, a caveman could do it!



For those with E79 errors and who have XBR3, try extracting your SMC from your xbr3 nand dump with 360_flash_tool and use the SMC_dec.bin (renamed to SMC.bin and dropped into your /data folder) when building your final freeboot image.


4. ** IF YOU GOT A E79 ERROR AND NAND PRO WONT DETECT YOUR FLASH "Could not detect a flash Controller" FOLLOW THIS GUIDE nand recovery mode


**If your avatars dont work after flashing freeBOOT from what I read (and what I assumed originally) you take the 9199 update and run it like any normal update. The xbox will recognize you have the 9199 update but that you are missing the avatar files so it will then just install the files needed for avatar support

Optional:

If you want xellous installed right before step 9 open up XeLLous_v1.0.zip XeLLous_v1.0 and extract xell-2f.bin and put that file into freeBOOT-0.031bin
(let it overwrite the old file) and then continue with step 10 and build your image.

I hope this helps clear the question for noobs such as me I just used some common sense to do this hope it helps enjoy freeboot and thanks to ikari for freeboot
