Are you on the samsung or google stock rom? IF its a google stock rom (yakju or mysid) then you should have got an update push but if you are still on the samsung rom then there is no update from them.
Mark.

Check my guide for an unlock procedure...that includes backing your applications up.

Where can i see if is samsung or google rom?(thx for reply)

If i may, that's something even google can find the awnser.
To make a nandroid, you need cwm/twrp. To have any of those, it is understated that you need to be unlocked, and stated on first post of each custom recovery you will find that a custom recovery needs to be flashed by fastboot, or... by a custom recovery already installed.

Again, this is wrong. There is no need to unlock if he is running 4.0.2 to install CWM.
@OP:
If you are not running yakju or yakjuzs, there is no update available for you. You either have to switch to yakju (see here) or wait.
If you are running yakju or yakjuzs, and want to get the update without losing any data do this:
1) Follow the procedure here to get root access.
2) Install ROM Manager and use it to flash CWM. Use CWM to do an nandroid backup.
3) Unlock your bootloader
4) Use CWM to restore your nandroid backup
5) Follow the procedure here to update.

[Q] Android with the red exclamation appear after OTA

Hi guys, each time that I try to upgrade 4.04 by OTA, it stopped and appear the Android with the red exclamation on it.
I've used the 'WugFresh unlocked toolkit' to root/unlock Galaxy Nexus.
For install OTA 4.0.4 from Google, I need to lock the phone again?
If I back to default configs - using WugFresh again - the OTA, and after the root/unlock, work without problems?
Thanks.

That's the stock recovery you're seeing.
What images have you changed?
If you revert to the stock ones (radio/bootloader/etc) you should get the OTA.

You are seen that screen because you have something on your device that is not stock. (Unlocked and rooted makes no difference.)
To be 100% sure that an OTA update will install automatically, you need to have all of the following:
1) the radio that came with the ROM that you are using;
2) the stock recovery that came with the ROM that you are using;
3) the stock kernel that came with the ROM that you are using;
4) all of the original files in /system that came with the ROM that you are using.
Have a look at the thread here. It is for manual installation of an update, but the requirements still apply to an automatic update OTA.

So if I uninstalled apps to the system and do the lock/unroot, this will cause problems when I try to upgrade from version 4.0.2 to version 4.0.4?
I uninstalled Google Maps, Youtube and Earth.

You are not reading at all at what efrant says and you havent looked at the link i provided.. Until you do so you wont go farther
Galaxy Nexus AOKP m5 Franco kernel m3

Yes, I read, but maybe I did not quite understand ...
To recap: I used Wug's Toolkit and now I can no longer install the 4.0.4 update official Google OTA. So I would like to know how to undo it, install 4.0.4 and then apply the Wug toolkit again.
According to the links, I need to undo the changes before, but I can not undo the root by Wug's Toolkit, because he can not download a file, appear an error message that could not be found.
What I wonder is, how to get back to what it was prior to applying the 4.0.4 update and then do the root again? Is that possible?
Thanks.

Forget about toolkits, follow this guide please

There are two ways to get 4.0.4:
1) Flash a full 4.0.4 ROM, which is what the link msedek posted is.
2) Upgrade 4.0.2 to 4.04, which is the link I posted a couple of posts back.
In the first case, you easily end up with a clean install, but your data is erased (so back up before)
In the second case, you need to make sure that you undo any modifications you made to the /system partition, the kernel, the radio, and the recovery. Then you apply the update, and you will have an upgraded ROM with all your data and settings intact.

Actually, this is true. I was having the same issues. When i rooted, I deleted system apps I did not want. For weeks and weeks I kept receiving the popup message saying that the update to 4.0.4 was available. When attempting to upgrade, it would always fail on reboot.
Just two days ago, I received the upgrade notice again. I immediately went into Recovery mode, and attempted to manually install the update file from the system directory. When I did, I received an error right away saying the update could not find "TabletBooks.apk" (I deleted Google Play Books since I dont use it).
I reinstalled a clean image of 4.0.2 I made with ROM Manager weeks ago, then applied the update to 4.0.4 again, and it ran smoothly with no errors, since all System apps were installed with the clean image I saved.
Hope this helps...

If you are going to install a clean image anyway, it doesn't make much sense to install 4.0.2 and upgrade to 4.0.4. Just install the 4.0.4 image immediately...

Because you cant just download the full 4.0.4 image and install it via Recovery, can you? I thought you can only install the full image via ADB?

Well, I'm not sure where you got a stock 4.0.2 CWM-flashable file, but FYI, you can flash 4.0.4 the same way if you have a 4.0.4 CWM-flashable file (or just replace the 4.0.2 image with the 4.0.4 image in the same CWM-flashable file.

Thanks, that's good to know! I come from HTC phones (G1, Nexus One, etc), so Samsung and modding is kinda new to me.
I had a CWM-flashable 4.0.2 file because ROM Manager created the image for me when I first rooted and wanted a backup of a clean stock ROM. I wouldnt even know where to find a CWM-flashable 4.0.4 file on the web. I only know of the stock source files Google has posted. I read that those files can only be flashed with ADB on a PC.
Thanks again!

Oh, you were referring to a CWM backup. I understand now.
But regardless, you can still flash the Google images via CWM, they just have to be packaged up in a CWM-flashable zip.

Use this to convert to yakju. Make sure you do all the optional steps in part D, and you will receive every OTA update. yakju is the first build that receives OTA updates, so I'm not sure I understood your initial concern.

not unless you modify some of the system files. if you leave everthing stock, you will get the OTAs properly and not have any issues.

Not if you follow the steps, and do the optional steps in part D. No problems.

Notes on optional items and other issues:
4) WHEN you get the update notification, IF you want it to install automatically, you will need to ensure that that you are using the corresponding boot, radio and recovery images for the .tgz package you downloaded. Otherwise, the update will not install automatically, but it will install using a custom recovery like CWM. See this thread for details.

what does this mean then??

means thats if you want the update to install, you need to have the radio, boot.img and recovery from the stock version that you are on. if you dont, it will fail on install.

These are the exact reasons why I went to 4.0.4 as well.
I think that it's worth it and I haven't had any issues either. In fact, it also fixed my random signal drop problems on the Rogers network as well.

That's right, if you have a different kernel (contained in the boot.img), the next updates will not work. You need to flash the stock kernel. Like in the link I had posted earlier.
That's what happens when you try to take shortcuts by using toolkits -- you could have easily backed up your data yourself by running a nandroid script...

Scared to update to 4.2 JB Pls guide

Model Number: Galaxy nexus
Android Version: 4.1.2

this is rooted and unlocked.
Now i am getting messages - system update available Android 4.2 Jelly Bean
I m scared. Should i update?
Will it affect my clockwork mod recovery or root and unlock issues?
Pls guide.

Download one of the roms in Development section..pick the stock OTA or Factory images or any of the custom roms..that way u can stay rooted and unlocked while still getting JB 4.2 (or 4.2.1)

if you want to apply the ota you will have to flash stock recovery.. and after applying it you will lose root so you will have to root again. like the other user said its better to just flash one of the factory image from the dev section

I have always used stock rom and just rooted and unlocked.
I am not very tech saavy.
I tried updating just by clicking on system update but got red exclamation point on rboot.
is there no simpler step by step way?

You have a custom recovery, as you have mentioned in OP..Hence you cannot update via normal system update.
Just download a rooted rom, put in your sd card and flash via CWM.. Voila! JB 4.2!
Advantage = stay rooted with unlocked bootloader, keep your apps (if you didnt factory reset before flashing, i dirty flashed 4.2 over 4.1.2, so far so good.) , awesome community support for roms
Disadvantage = can't update normally.

Before flashing a new ROM I would update your recovery first.

[Q] Howto delete pending OTA update

I have a yakju GNex with stock 4.1 (unrooted). It has the 4.2.0 update on it - it has tried and failed to install this update several times.
I would like to delete this pending 4.2 update, so I'm wondering where I would find the relevant files.
I figure that, once I've deleted them it might automatically download and install 4.2.2 (and hopefully that will install properly), and if that doesn't work then I will try to manually flash 4.2.2. Either way, I'd like to start by deleting the pending update.
Thanks.

4.2.2 requires 4.2.1, which requires 4.2
you modified system files and thats why the OTAs fail to flash. i swear i'm beating a dead horse by saying that.

Thank you for clarifying about the OTA being dependent on each other. I take it that applies to the OTA, and not to the published Nexus images so I could still download 4.2.2 and flash it to the phone (bypassing 4.2).
I can see why you suspect that I have modified system files, but I have not. It has stock, unrooted, yakju 4.1 on it.
The only thing non-standard about it is that a Canadian GNex, with an unlocked bootloader, and flashed (via fastboot) to the standard Google firmware. But that is extremely common here, and the problem I'm having is not extremely common, so something must have got mucked up on the phone.
Regardless of how it happened, I would still like to delete the update files if it can be done w/o root.

Now I think that is wrong...
I 'reset' the phone - using the option in settings that erases user data.
It appears that this cleared the pending update, as a day later I was prompted with a new OTA install, but now it was for 4.2.2. I confirmed that I was still on 4.1.1 and it was offering me an OTA update to 4.2.2.

No, it did not. But I believe that the problem that prevented it from installing OK is the same problem which brought me here in the first place. I don't think it would have offered me the 4.2.2 if that update was not suitable for me.
In the end, I downloaded yakju 4.2.2 stock from the Android Nexus Images page, and then followed efrant's instructions in post#1 of this thread:
http://forum.xda-developers.com/showthread.php?t=1626895
I did each of the fastboot flashing steps, including the optional ones, to get the best chance of overwriting whatever was causing the problem. This worked and the phone is now running 4.2.2.
