You will need to have the phone unlocked have clockwork recovery installed and the latest version of the su.zip to flash via clockwork. Here is an su that should work in 4.0.4: http://android.strifejester.com/common_files/SuperUser.zip

You can get the latest CWM at clockworkmod.com if the 4.0.4 update replaced your recovery.
