For those of you who want to install the latest Android 4.0.4 OTA IMM76I update from Google, the latest stock ROM, here’s how to do it. Also, this is an unroot method back to stock. It will erase all your personal settings and apps so, be sure to make a backup of your ROM, backup your apps using Titanium backup app, and also make sure to backup SMS text messages (if needed) using SMS Text Backup app.
*Note – This is ONLY for Galaxy Nexus GSM, not for Verizon/Sprint versions.
Step 1. Take the battery out and put it back in. Then hold down Volume Up, Volume Down, and Power button together until you enter the fastboot mode.
Step 2. Connect a micro-USB cable from your Galaxy Nexus to your computer.
Step 3. Under Device Manager, make sure you have something like “Samsung Android ADB Interface”. If you don’t, manually update the drivers. If you have trouble, watch the video as I walk you through this part in the vid. (Download drivers here) For Mac and Linux, you don’t need drivers, skip this step.
Step 4. Download GalaxyNexusUnroot404.zip and unzip to your Downloads folder.
Step 5. Open up a command prompt (or Terminal for Mac or Linux) and type:
fastboot flash bootloader bootloader-maguro-primela03.img
fastboot flash radio radio-maguro-i9250xxla02.img
fastboot -w update image-yakju-imm76i.zip
For Mac, replace fastboot with ./fastboot-mac.
For Linux, replace fastboot with ./fastboot-linux.
You can also do:
fastboot oem lock
to lock your bootloader if returning phone for warranty.
Step 6. Once done, your phone will reboot and you should be on stock Android 4.0.4. Congrats!
