[Solved] Downgrade Galaxy Nexus from jb to ICS-->You did it? help me please :)

It sounds like i am a idiot, but I am facing a lot of problems on jelly bean (official).
Is it possible to downgrade my official jb software to ICS 4.0.4 official without having to root it?
Sorry for my noobness, I am new to this device
Thanks for your time

that guide doesnt require root or cwm... just an unlocked bootloader.

I don't have that too... And I want to revert back to ICS
Is it possible??
Sent from my Galaxy Nexus using xda app-developers app

without an unlocked bootloader... no not really. even if you used ODIN, it would unlock the bootloader then relock it.
is it really so hard to type: fastboot oem unlock ?

its either manual or ODIN.
i will always prefer manual since its not that hard.
either method will wipe your device too btw.

I see, does it matter which command prompt? Is stock windows vista or Ubuntu good for it?
Sent from my Galaxy Nexus using xda app-developers app

the guide is generically setup for windows. for ubuntu, you just need to use ./fastboot-linux instead

already a couple threads on this.

Yes but that was the hard way the way I done it is easy

All u do for 1 I used is download files and do instructions no need to unlock boot loader or any think like that
Sent from my Galaxy Nexus using xda app-developers app

using a unsupported tool like Odin could get you in trouble and with no chance for official support from Google nor Samsung. I suggest you use fastboot.

Also with factory images provided by google you just need to set up adb & fastboot and execute the .bat script.
its easier than using odin like bk201doesnotexist said.

Help going from yakjuxw to takju in the UK

there is so many same or almost same threads...
From YUAKJUXW or other build to YAKJU or TO Takju is really easy!
You need to move important files from nexus to PC and then to download fastboot and then to unlock bootloader which will wipe all data and then download factory image and then extract from factory image package (.tar) the -img files and .bat file or all files to fastboot folder and plug Nexux to PC via USB and run flash-all.bat file!
on Linux you have to use the .sh file
on windows .bat or .cmd

Thank you for your advice but I wouldn't feel confident or have to knowledge how to do it. I am hoping to find someone in my area who does this and knows what they are doing.

OK! It's easy to do and I had before Yakjuxw but it took too much time to get updates for it so that's why I'm using Takju on my nexus.
The links that I gave you just follow those guides and you will have takju on your nexus...
there is not easier way to do that..
In YouTube is at least some good tutorials how to flash yakju to yakjuxw and you can do the same with takju files..

Stock 4.1.2

Need a download link for #galaxynexus maguro jb 4.1.2 GSM stock rooted rom ,anyone?
Sent from my Galaxy Nexus using xda app-developers app

Come on people search the forums and internet more please!
Google Factory Images for Nexus Devices
Download 4.1.2 (JZO54K) for either takju or yakju
flash required 'img's in fastboot
flash a custom recovery
search for a cwm.zip that gives you root
rejoice.
I'll tell you how to do it but I'm not going to hold your hand. This stuff is far too easy... You've been here long enough. Search next time!

Download the Galaxy Nexus Toolkit. You can use it to download the stock img and flash via fastboot.

Stock Galaxy Nexus from Fido

My girlfriend has a stock nexus from Fido. She's fine with it being completely stock so long as everything works. That was the case up until about a week ago when she started having random reboots every day. She's now fed up and is open to the idea of me flashing a different firmware on her device. I explained to her how the updates work with her device.
So from what I've read, I think the best option would be to flash Googles official stock (most current) firmware that would be found on the devices from the play store. I've taken a quick look through some of the stickies and there is a lot of information which is great, but it can also be a little confusing. What would the exact process be to flash a different firmware image to this phone if she has a locked bootloader, no root access, and running 4.2.1 from Fido?
Any help is much appreciated

Easiest way for you would be to use a toolkit. You can either use mskip's or wug's toolkit. There is an option that does all the steps for you in one click ( wipe, unlock, root, flash ROM...)
Just make sure you install SDK for Android first. Check YouTube videos if you're not sure on how to do it. Once you're all setup, you'll be able to flash anything you want.
