FOOLPROOF INSTRUCTIONS UPDATED
You will need fbbuild 0.1, Freeboot 0.032 (you only need this for ibuild.exe), 12611.zip (this contains the new dashboard files), Dashlaunch 2.04 (You only need this if you already use an old version to autoboot to your dash)
1. Copy flash360 to a usb stick and run on your JTAG if you already have flash360 on your xbox hard drive then run it from there,
2. Make a dump of your NAND (I did not do the full dump).
3. If you don't alread have your CPU key then do the following - Power off the console, plug in either a component or composite video lead, then power on via the Eject button. Note down your CPU Key.
4. Extract fbBuild 0.1 to a folder on your PC, and place your flashdmp.bin from step 2 in the same folder.
5. Find ibuild.exe from freeboot 0.032 and copy that to the fbbuild 0.1 folder in step 4. Create a folder called temp in the fbbuild folder.
6. Hold down shift and right click on the ibuild 0.1 folder, select "open command prompt here". At the command prompt type ibuild.exe x -d temp\ -p CPU_KEY -b DD88AD0C9ED669E7B56794FB68563EFA flashdmp.bin (replace CPU_Key with that you got in step 3)
7. Extract the contents of the 12611 Dashboard to the data folder in the fbbuild folder.
8. Also copy crl.bin, crl.bin.meta, extended.bin, extended.bin, kv.bin, odd.bin, odd.bin.meta, secdata.bin, secdata.bin.meta, smc.bin, smc_config.bin from the temp folder created in step 6 to the data directory. If you are missing some of those files, you should be able to find them in the Donor NAND's archive.
9. At the command prompt type fbBuild.exe -c MOTHERBOARD -d data -b DD88AD0C9ED669E7B56794FB68563EFA -p CPU_KEY updflash.bin. (replace CPU_Key with that you got in step 3),( replace motherboard with either XENON, ZEPHYR, FALCON, JASPER, JASPER256 or JASPER512). This will create a file called updflash.bin
10. Copy updflash.bin either to a USB stick. Or copy it to the flash360 folder on your xbox hard drive.
11. Now flash the NAND with flash360. I chose to keep my existing kv file.
12. When finished and you click a button the xbox will shut down. Now unplug the power and leave for a couple of minutes.
13. Reconnect. the first boot will go to a black screen for about a minute so dont worry.
14. Set up the xbox to your settings.
At this point you will not have Avatars or full Kinect Functionality.
15. Now download the dashboard 12611 system update and copy to the root of a USB stick.
16. Power down the xbox and plug in the usb stick in the back. Switch on and say yes to the update.
NOW THE DASHLAUNCH UPDATE (only need if you are already using dashlaunch)
17. From the Dashlaunch zip you will find a folder called installer. FTP this to the xbox and run and it will update your old dashlaunch to work with the new dash.
Hope this helps people.
