If you've been waiting for Android 4.1.2 to hit your GSM Galaxy Nexus (yakju), wait no more. Google has already begun the OTA process, but in case you haven't gotten yours yet, we've got the direct link for manual installation. Yay for you! Here's how to make it happen.

First and foremost, you'll need to meet a couple of prerequisites:

  • You must be using a yakju device. Not takju, yakjuux, yakjuxw, or any other variant. If you're not sure what build is on your phone, crack open /system/build.prop and see what it says.
  • You must be on build JRO03C.

So long as those qualifications are met, you should be all set. Grab the download and get ready to flash.

Like with all GNex manual installations, there are a few different ways to apply the OTA depending on your setup, including the "adb sideload" method that works even on full stock. Fortunately, there's an excellent thread over at XDA with detailed step-by-step instructions for each possible scenario. I recommend reading through the entire set of instructions before beginning - once you're ready, give it a whirl.

Enjoy.

    Or you could just open maps and go to Settings>About for takju/yakju.

    I just did a system update check and mine automatically started downloading. same build. ota must be pushing out now.

  • Daniel

    Just read this and noticed a message on my phone, Glalaxy Nexus, about a update to 4.1.2. As I type this the phone is updating OTA. Im in the UK on Virgin mobile (sim only).

    • mattrition

      This is disturbingly similar to my setup but I don't have the update yet :p

      And when I say disturbingly similar, I mean UK Gnex on Vodaphone SIM only.

      • mart6049

        Have you manually checked to see if its there?

        • mattrition

          Yes. If there is something that I learned last OTA-day, it's that the only thing that determines when your phone gets an update is probably a random ID in your phone's hardware possibly :)

          • mart6049

            Im sure it will be on its way soon :)

    No love for "Takju" version ? :( Is this happens every time that "Yakju" users get the update 1st ? If so i will flash "Yakju" ROM

    • http://www.androidpolice.com/ Artem Russakovskii

      Do you have the links to the other ones? We've only seen the urls for the N7, the XOOM, and the GN yakju so far.

      If you're talking about the full factory images, those require a wipe.

      • http://jeremyperez.com Jeremy

        If one is already OEM unlocked, you should be able to just flash bootloader, radio,(although I don't think they've changed from 4.1.1) and the system img files from the factory image archive to upgrade to 4.1.2. As long as userdata.img isn't flashed all data should stay intact.

      • http://twitter.com/epic_n00b $(‘#Anil’)

        zip file is now available on XDA for takju version, but where is my update ? I have purchased a Nexus device from Play store to get timely updates and not to update it using help from XDA. :(

        • http://www.androidpolice.com/ Artem Russakovskii

          Can you link it please? I can't see it.

  • wickets

    thanks for the heads up

  • Alex P.

    Lat time I flashed my takju cause they got ota before yakju, and now it can't find the OTA update. Yakjus update first. Come on!

      • Alex P.

        Good one. Anyways, i am gonna flash the full factory image cause i am selling my GN.
        Just wanted to make sure that they fixed the unlink notification/ringer sound problem in 4.1.2.

    • patapongirl

      LOL. Same here.

      I'm too lazy to go back to yakju so I will just wait.

  • boogie_monster

    Don't you mean "JZO54K" instead of "GZO54K"?

    anyways, I had a YAKJUZS device when I first got my GNEX so to have a pure Google phone I falshed it to YAKJU, but then again when TAKJU came out, since it was the phone Googlers were using and it was the one selling on Google Play I thought it will get the updates faster so I flashed TAKJU over it, now I think I should have stayed with YAKJU, lol.

    BTW can anyone confirm that on 4.1.2 screen rotation works on stock launcher? or at least tell us what has changed?

      Same remark here.
      @Artem Russakovskii : maybe you'll update the title to the correct version.

    • SuperAndroid

      Screen rotation is not available on Galaxy Nexus. The only difference between yakju and takju is Google Wallet (available in takju and not yakju).

      • boogie_monster

        Thanks for the info.

        Yes I know about the difference but back then I thought well since Takju was the device that Google gave away at the 2012 IO and is also the one available on the play store, it should also be the one that receives the updates first. I guess I just go ahead and flash the factory image that Google posted online. thanks again for the confirming that screen rotation.

  • Christopher Wilmeth

    It's so frustrating when I see news and the author expects me to know what a yakju or jakju or whatever is. There is nothing in the about section of our phones that says that explicitly and you guys just assume we're all rooted device experts. Gah. Tone it down for some of the average users please.

  • Mike

    I just received an OTA update for 4.1.2 on my nexus s (Wind Mobile Canada).

    • http://www.WonhoPhoto.com/ Frank Lee

      same here, for my Nexus S on T-Mobile USA

  • http://twitter.com/LV2355 Laurentiu

    Thanks!

  • palo

    Is rhis for the gsm galaxy nexus from Google play store also??? If so I still can't pull up the update ,but I don't havewi fi until later would that be a reason?

  • http://www.facebook.com/profile.php?id=202301834 Eloy Tavera

    Tried updated but was aborted, I forgot I had uninstalled the stock MMS app. I have been looking for the apk with little luck and have only found gapps for CM or AOKP. Does anyone know where I can find the stock Jelly Bean MMS apk?

  • https://steamcommunity.com/id/m-p-3 m-p{3}

    I guess yakjuux images will come soon..

  • http://www.facebook.com/idan.yael Idan Yael

    I am on the yakjuxw... no update for me. damn it!

  • https://twitter.com/#!/Cuca64 Nino_64

    OK here we go again; when us sprint n Verizon users are going to get the update ? :(

  • CK

    Hi Everybody. I just received the 4.1.2 update for my Galaxy Nexus (stock yakju, unrooted, locked, open line network). There is not a whole lot of difference. Only difference I see:
    - 1 finger scroll down and scroll up expansion for notifications. This is cool!
    - Some check boxes have now become toggle switches (big deal right?)
    I can confirm that the stock launcher DOES NOT have landscape swivel (i personally dont like it anyway).
    Project butter seems to have gotten a little more buttery.The 2nd app screen lag seems to be gone now.

    Thats it. Don't keep your expectations too high. Looks like most of the changes are under the hood.

    • CK

      Oh btw, I used the force OTA method. Apps>Google services framework>force stop>clear cache. Now go to Settings>About>Update. It took me about 5 tries before i got my update. Enjoy!
