All thanks to an Android Central’s Forum member, the Verizon Galaxy Nexus Android 4.0.4 is now available- unofficially. Apparently this member, upon being notified of the update, managed to not only get his hands on the file but also uploaded it. A change-log does not accompany the update, as of now. The update uploaded is exclusively for the Verizon Galaxy Nexus. If you choose to try it on your GSM Nexus, it could brick your device.
You will need:
- A Verizon Galaxy Nexus. This one’s a bit obvious. (This process will also work for GSM Nexus updates).
- The Android SDK installed.
- Fastboot. (Either Windows or Mac version).
- An unlocked bootloader.
- The unofficial update of the Android 4.0.4.
- The latest Clockworkmod recovery image.
(Follow the links to get whatever you don’t already have.)
Follow these instructions:
- Copy the OTA package above to the /sdcard folder on your device
- You will need to drop the ClockworkMod file in the folder that contains fastboot (on your computer) in the SDK folder. (This will be either /tools or /platform tools). Rename it to cwm.img. This will make things easier for you.
- To re-boot your Nexus to bootloader mode, hold both volume-up and volume-down buttons, and then press power.
- Plug your device into your PC and open a command prompt or terminal. Navigate to the folder that has both fastboot and the cwm.img inside it.
- Type this: fastboot-windows.exe boot cwm.img, at the command line. Alternatively, type fastboot.exe if that’s all you have.
- Use the ClockworkMod recovery menu to flash a zip file from the SD card. Next, select the OTA zip file you must have downloaded earlier.
- Let things happen on their own now.
Once you’ve followed the installation process correctly, you should be running Android 4.0.4 on your Galaxy Nexus. It takes a lot of steps, but once you begin to boot into ClockworkMod recovery contrary to flashing it to your phone first, it gets better. Let us know how it goes, or comment if you need any help.
