The Android 4.0.4 OTA update started rolling out to the GSM Galaxy Nexus yesterday (where's the love, Verizon?), but many users are still without the update. Fortunately, the official update is now available for download directly from Google. Getting it installed, on the other hand, is a bit of a task. We've done most of the legwork for you here, so follow the below instructions and you'll be running 4.0.4 in no time.
Let's get started.
This update is for 4.0.2 to 4.0.4 only. If you're running any other version, don't flash this.
