What is this FASTBOOT method exactly? For those who don't like using Odin I have taken the time to put together a little script package that will install the 4.0.4 "leaked update" using the device's bootloader and "fastboot" from the Android SDK. You can normally achieve this by entering in commands to flash these but I have gone a step further and made a script to handle this for you. Also included in this package is the option to flash CWM recovery and Superuser access if you choice to do so.
Thanks to Korey Nicholson @ xda developers for providing this leak of the official 4.0.4 update.
