Never used it, no harm in trying and letting us know how you get on

Build Instructions (Updated for latest xeBuild v1):

For simplicity you need the following:

1) Your CPU Key
2) A copy of your nand (original or FreeBOOT) and SMC
3) Dashboard Data (Google for "xxxxx Dashboard data" where XXXXX is the version number e.g. 12611, 13599, 14699
4) xeBuild (xbins -> /XBOX 360/development/xeBuild/)

Getting ready
Download xeBuild and extract it to a folder - say C:\xeBuild

Open your dashboard data zip file and extract the contents to C:\xeBuild\<version_number> e.g. for 14699.zip, extract the contents to C:\xeBuild\14699. The folder should already exist in C:\xeBuild anyway.

Edit C:\xeBuild\1blkey.txt. On the first line is a dummy key - replace it with DD88AD0C9ED669E7B56794FB68563EFA

Edit C:\xeBuild\mydata\cpukey.txt. On the first line is a dummy key - replace it with the CPU key of the console.

Extracting KV and SMC_CONFIG.bin
Open up 360 Flash Tool v0.97 and click Settings->Options. Tick the box that says "Extract ibuild compatible files". Then open your nand and click extract on the bottom. Tick the box for 'config blocks' and 'Keyvault' and click OK. Choose a folder for these files. When extraction is done, go to that folder and there'll be a folder called freeBOOT, click into it, then into data and you will find two files - kv.bin and smc_config.bin. Copy these two files to C:\xeBuild\mydata.

Picking the right SMC (not for Xenon consoles)
This step is very important if your console is not a xenon - flashing the wrong SMC can end your JTAG If the nand file you used to extract the KV.bin and SMC_CONFIG.bin files in the previous step was taken from your previous dashboard updflash.bin, or was taken from a dump you took off your currently working JTAG, then use the same steps above but check the box labelled SMC. You'll find an SMC.bin in the same place you found KV/SMC_CONFIG.bin.

If you're using your original nand (not recommended unless you know your wiring scheme), then you will need to pick an SMC for the JTAG wiring in use. You can find SMC files for the AUD_CLAMP method of wiring (the preferred choice) in this file. Remember: Using the wrong SMC file can b0rk your JTAG, to play it super safe, take a dump of your nand using Flash360, and extract the SMC from that using 360 Flash Tool

Copy smc.bin to C:\xeBuild\mydata


Setup xebuild

Place an existing nand dump into the 'mydata' folder of xeBuild. This will allow xeBuild to determine various system variables. You need to rename the dump file to 'nanddump.bin' without the quotes.


Build freeBOOT
Open a command prompt, go to C:\xeBuild and type the following

xebuild -t <image type> -c <model> -d mydata -f <dashboard> updflash.bin

<image> is either glitch, jtag or retail
<model> is either xenon, falcon, zephyr, jaspersb, jasper256, jasper512 etc etc
<mydata> is where your per-console files are, cpukey.txt etc
<dashboard> is the name of the folder holding the dashboard files (e.g. 14699)

xeBuild will build freeBOOT as updflash.bin - copy it to USB, boot to Xellous and flash it.

Post-Install

Download the full system update - www.xbox.com/en-GB/system-update-usb
Check the version number in the filename matches your newly installed dashbaord version.
Extract to a USB stick (blank)
Insert USB stick into console
Power console on, accept the update, the console will apply and then reboot.
