[Your camera may brick so DO IT AT YOUR OWN RISK!]

Your camera may brick so DO IT AT YOUR OWN RISK!

You have to follow these steps in order to try the Audionut ML build and the dual iso module:

You'll Need This Files:

7D firmware v1.2.3 http://pel.hu/down/eos7d123.exe (Thanks to Pelican)
EOScard software http://pel.hu/down/EOScard.exe (Thanks to Pelican!)
EOS Utility 2.8.1 https://dl.dropboxusercontent.com/u/43043701/EOS.zip
patch.bsdiff https://ml-devel.googlegroups.com/attach/1608f00c71abc464/patch.bsdiff?part=6
bsdiff.exe and bspatch.exe http://download.pokorra.de/coding/bsdiff_win_exe.zip

Enabling Bootflag:

Unzip the bsdiff_win_exe.zip file in any folder. In my case i extracted to a folder in my desktop C:\Users\Miguel\Desktop\Magiclantern\
Double-Click eos7d123.exe and unzip it in the same folder. It should extract the 7d000123.fir file in the folder.
Place the downloaded file patch.bsdiff  in the same folder
Open "cmd" by pressing WindowsKey+R and typing cmd
In the cmd screen change the directory by typing cd "folder where you put the files", in my case it was cd C:\Users\Miguel\Desktop\Magiclantern\
Type bspatch.exe 7d000123.fir firmware.fir patch.bsdiff and press enter
It should generate a file called firmware.fir that we are going to use with EOS Utility.
Copy the firmware.fir file to an empty CF card and put the card in your camera.

Extract EOS.zip in some other folder. In my case i extracted to C:\Users\Miguel\Desktop\Magiclantern\EOS Utility\
For me it worked well but is possible that this EOS Utility wont work because of some missing driver or registry key, so make sure you have installed any Canon EOS DIGITAL Solution Disk before.
Connect the camera to the pc via usb cable.
Go to the folder that you've extracted EOS.zip and double-click EOS Utility.exe *
Click Camera Settings/Remote Shooting option. Make sure your camera dial is in M mode and Liveview turn off.
In the middle of the window click the icon that looks like a cross and a tool, between the Lightning/Flash icon and the Star icon.
Click Firmware Ver. 2.0.3 at the bottom of the list.
Click OK and Select the firmware.fir file from the first folder. Click OK Again.
Wait until is done. **Be very Careful**

Installing ML:

Now put the CF card in your computer. Delete the firmware.fir and the other files.
Open EOScard.exe, click EOS_DEVELOP, BOOTDISK, right-click the ML icon, select Ports in progress and click 7d 2.0.3 alpha2.
Wait until is downloaded and click Save in the upper right corner.

DONE!

This build already contains the Dual Iso Module, It is not enabled by default and you can enable it for testing but some people are having issues with the module so do it at your own risk.

* If the Camera Settings/Remote Shooting option is greyed out follow this steps:
Go to Device Manager by pressing WindowsKey+R and typing devmgmt.msc
Expand the Portable Devices tree and Disable all of them except Canon EOS 7d by right-click - Disable.

Feel free to ask anything, i'll try to answer as soon as possible. Excuse my english
