Default Steps to Downgrade to 4.0.1? GSM

While most people are loving the 4.0.2 update, I'm very disappointed. My battery life has gotten significantly worse, with the exact same usage patterns. No new apps or widgets installed.

I have unlocked my bootloader successfully. I've read through this thread http://forum.xda-developers.com/show....php?t=1419170 but it feels like they're not talking about the stock images here http://code.google.com/android/nexus/images.html , and are rather talking about the incremental updates.

I have the file that I want (ITL41F) downloaded. Can anyone post some step by step for me to install it and change my build.prop so that I stop getting that update notification?

Download the factory image.

Extract it

Open the script and run each fastboot command manually. Omit the -w flag on the last one unless you explicitly want to wipe.

Thank you. Can anyone show me how to change the build prop properly so that I can stop getting the update message?

build.prop is in the system partition, which as an unrooted user, you will not have the necessary permissions in order to alter it.

ps.
Code:
fastboot flash bootloader bootloader-maguro-...
fastboot reboot-bootloader
fastboot flash radio radio-maguro-...
fastboot reboot-bootloader
fastboot -w update image-yakju...
HTC Desire → HTC Desire S → Samsung Galaxy Nexus → Samsung Galaxy S3 → LG Nexus 5

Thank you, I'm going to root to do it. After I do so, can you tell me how to edit the build prop appropriately?

Maybe I'm missing something here.. but if you're not happy with 4.0.2 and you're willing to go through the trouble of going back to 4.0.1, why not just flash 4.0.3?

Are you REALLY going to just stay on 4.0.1 for the rest of your time with the phone and never update?

It's my understanding that 4.0.3 is AOSP and is compiled into some custom ROMs....I want to stay as stock as possible...once 4.0.3 official is rolling out, I'll let it upgrade. Can you help me put the proper things I need in the build.prop to stop getting the update?

There are many ROMs out there that "stay as stock as possible" with a few tweaks because it is a necessity.

So I used root explorer to replace the build.prop in the system directory with the one from that custom ROM linked to above...shouldn't that have done it? I am still getting the update message.

Once you have flashed back to ITL41F, you need to edit the line in the build.prop file that starts with ro.build.fingerprint. Change it to this:

ro.build.fingerprint=google/yakju/maguro:4.0.2/ICL53F/235179:user/release-keys
