I don't use Windows, so you may need to set up a VM running something like Ubuntu to sucessfully do the update.
The images from the google update are a 'Sparse EXT4" volume. You need to use utility called simg2img which can be found within ext4_utils.zip (attached to the following)http://forum.xda-dev...d.php?t=1081239
Download the sources, and compile them by using 'make'
Then extract the system.img from the Google Update to the folder where the simg2img binary has been compiled, and type:
#./simg2img system.img sys.img
This will create a sys.img file (around 640MB), copy this new file (aswell as the boot.img file extracted from the update) into dsixda/original_update
and run the kitchen
As a quick note, Don't run simg2img on boot.img, it's not needed!
