Install/Flash Android 4.0.4 ICS (IMM30B) On Verizon Galaxy Nexus [How-To Tutorial]

Google’s Nexus series of “Android experience” smartphones are always first in line when it comes to getting the latest updates to the Android OS. The latest Nexus device – the Samsung Galaxy Nexus – is currently on Android 4.0.2 and, today, we’ve received news of a leaked build of Android 4.0.4 for the Verizon Galaxy Nexus.

According to the source, there are plenty of small changes that make up for an overall better user-experience: it is “noticeably faster”, has new radios that increases signal strength and makes switching between 3G/4G faster, has faster boot up time, has fixed Android OS battery bug, has increased volume and more. You can read the unofficial changelog here.

We’ve got a step-by-step guide on how to flash the leaked build on your device right now. Check it out after the jump.

Galaxy-Nexus

Before you start following the guide, please note that this is a leaked, unofficial ROM. We actually suggest you wait for Verizon to release this themselves just to be on the safer side of things. Besides this, you must be on a rooted Galaxy Nexus on Android 4.0.2 (ICL53F) with ClockworkMod installed for this guide to work.

DISCLAIMER: Redmond Pie will not be held responsible if you lose data or your device gets damaged in the following of this guide. Proceed at your own risk.

Step 1: Download Android 4.0.4 ICS (IMM30B) [MediaFire] for Verizon Galaxy Nexus (This DOES NOT work on other Galaxy Nexus phones). Rename this to update.zip to transfer it directly under /sdcard on your Galaxy Nexus.

Step 2: Shut down your Galaxy Nexus. Power it back on while holding down the power button and the volume up and down button simultaneously until you boot into ClockworkMod Recovery.

Step 3: Take a NANDROID backup.

Step 4: Navigate to install zip from sdcard > apply /sdcard/update.zip

Step 5: Once the ROM has been flashed, select reboot system now.
