There seems to be a lot of information thrown all around the place regarding the Jelly Bean update. But there are a lot of users who have not rooted, flashed or updated their phone outside of OTA cycle before and all of this is rather intimidating.

With Jelly Bean, there seems to be issues with different phones, radios, firmware and ROM's and it's just all a huge mess. While people who have done it before possibly have no problems, a lot of users have not. The threads that have shared ROM images have not been clear about how the update works, unless you have done it many times before.

Could someone please write a simple step-by-step guide how to update stock yakju 4.0.4 Galaxy Nexus to Android 4.1 Jelly Bean?

I am sure a lot of people would appreciate this, me included! Thanks!

EDIT: The post below is the recommended guide, thank Camazza for posting!

I'll try since I updated my yakju some hours ago. Here's what I did, but should work with every ROM.

1) Download and install the Galaxy Nexus Toolkit. It's awesome.
2) Download the ROM
2b) Put the ROM zip file on your phone wherever you like
3) Turn off your phone, press Volume UP + DOWN and then press power, you should then be in bootloader mode.
4) Connect your phone
5) If driver installation fails, open the Toolkit and choose option 1 (Install Drivers), then reconnect.
6) Open the Toolkit, choose whatever rom you have (I still have to find out if it really makes a difference for the options we're going to use)
7) Select Option 3 and confirm from Phone (WILL WIPE DATA) <-- NOT NECESSARY IF YOU ARE ALREADY UNLOCKED
8) When in bootloader mode again, choose option 9 and then Option 1
9) You should see CWM. Choose "install zip from sdcard"
10) Select the file you sent to the phone on step 2b
11) Wait.
12) Wipe data/factory reset
13) Reboot

YAY! You now have Android 4.1 Jellybean
This guide was written mainly for Stock users, as more advanced users probably already know how to flash a ROM.
Please correct any errors I may have made.

This is one of a way, but i encourage OP to read up on ADB and fastboot and try to do it the manual way.

I'd just like to call out OP on this thread for sort of shady use of [HOW-TO] thread-title tag.

You asked a question, you didn't provide a howto. Don't pretend you did :)

Not trying to be an asshole or anything, but if enough people are inaccurate in their use of tags, searching the forums later just becomes impossible and every thread needs to get repeated on a weekly basis.

Agreed. Familiarity with ADB is vital if you're going to root your device. Because if you can't access the bootloader or recovery, ADB is your only hope.

Sent from my Galaxy Nexus using xda premium
The Jellybean update gave me an opportunity to root the manual way.

I admit i used the toolkit to root, that was when i know nuts, frankly it's not hard, give it a few days, you will roughly know what to do.

But what was all this talk about radio firmwares and whatnot? You don't mention anything regarding them?

I left the tag, but edited it and referred to Camazza's post

Look, OP asked for a simple way. That's a simple way. People looking for an easy guide won't be running custom roms (as I wrote in the how-to).
I understand the importance of being able to use ADB (and I know my way around it), but that's not the aim of this guide.

Exactly, I don't want to meddle with custom ROM's and whatnot. I just want the latest version of Android from Google on my Nexus phone and so do majority of others I believe.

But this radio thing is still confusing to me, what are all the other threads talking about? I don't need to update some firmware separately to this?

It's all in there. You should have the latest LF1 radio when flashing this.

You don't have to flash the new radio. There is a new radio available, but it isn't necessary to flash it. If you do want to, you can either flash it with fastboot or there may be a CWM flashable .zip available.

Oh thank you so much! I'm a tech-guy myself and have developed for Android, but the whole rooting-flashing-updating business paired with the fear of bricking have kept me away from knowing anything more than Android app development.

This is really appreciated, I've done this before (when 4.0.4 was released), I just got very confused by the multiple threads and posts that talk about extra steps and radios.

Can I just use fastboot to boot into CWM and apply the linked Rom via "install zip from sdcard"?

I got it updated and can confirm than the posted step by step does indeed work, no problems so far. I was slightly worried while the device was booting up very slowly, but other than that everything seems perfect!
