Following the announcement of Android 4.3, the new Nexus 7, and the Chromecast, Google just started pushing the Android 4.3 open source code to AOSP (Android Open Source Project) under the tag android-4.3_r2.1. The push began several minutes ago and is expected to complete within a few hours. Additionally, factory images are already available for the Nexus 4, 7, 10, and the Galaxy Nexus.

Update 11:04am: According to JBQ, the push is complete: "All the files have been replicated to the git servers. If something's not working at this point, it's a bug."


JBQ, our favorite release master, took the creative route to announce the AOSP push - have a read:

Google Airlines welcomes you on the ground in Android International Open Source Airport Project. The local time is exactly 4:30 pm. We will be taxiing for a few minutes to our gate JSS15J while ground support guides us to the public git server.

We hope that you had a pleasant flight and we welcome you to Jelly Bean, or that you have a conflict-free rebase while connecting to your final version.

Your source files will be delivered down the https://android.googlesource.com stairs, in hall jb-mr2-dev, on carousel android-4.3_r2.1. Oversize kernel source files will follow a few minutes later at the counter.

Customs forms are available at https://developers.google.com/android/nexus/drivers and need to be filled before starting a device build, even if this is not your first trip to Jelly Bean. 

If you forgot to pack something in your luggage, pre-packed luggage is available at https://developers.google.com/android/nexus/images that contains everything you might need.

Should you have any questions, our agents are standing by at the android-building Google Group. Complaints and suggestions can be filed at http://b.android.com. Volunteers can head to the android-contrib Google Group, and job applicants to http://google.com/jobs

Even if you've visited Jelly Bean before, you will notice that our graphics public transportation is now smoother and more energy-efficient. The city is also safer for everyone, with an entire block dedicated to children. Location Hill was renovated, and the repaving of Bluetooth Avenue continued all the way to BTLE Street and AVRCP 1.3 Park. Our filesystem garbage collection service can now handle active households that generate a lot of trash.

On behalf of all of Google Airlines and of our Android ground crew, captain Conley and cabin chief JBQ wish you a pleasant experience with Android 4.3 and we hope to see you again soon.

Jean-Baptiste M. "JBQ" Queru
Technical Lead, Android Open Source Project, Google.

Having such timely access to both AOSP source and the factory images is very refreshing and shows that at least this part of Google is now running like a well-oiled machine. Access to AOSP code means custom ROM development can begin immediately, and you should see the first 4.3 builds of your favorite ROMs show up soon.

Update: CyanogenMod 10.2 confirmation announcement.

Update #2: Paranoid Android announcement.

Update #3: For those a bit confused on why we have JWR66V for current Nexus devices and JSS15J for the new Nexus 7, JBQ explains:

JWR66V is 4.3_r1 - that's the one that goes on existing devices.

JSR78D is 4.3_r2

JSS15J is 4.3_r2.1 - that's the latest one, on the new Nexus 7.

The JW builds were split early, to shield existing devices from the risk of destabilizations introduced by last-minute changes for the new devices.

    I wish we could reliably force OTAs (nexus 4).... but I understand why they roll it out.

    • Simon Belmont

      Me too! Waiting here with my Galaxy Nexus and Nexus 7 at the ready.

      I may just do a clean sweep on both and flash the factory images via ADB and fastboot. Command line, whee!

      • Steve Williamson

        Doesn't normally clearing some apps cache does this.. Which I could remember which tho lol

        • Havoc70

          Google Framework services is the only one i remember and its not helping, already tried it numerous times

          • anon

            I tried clearing the data for Google Services Framework at least 20 times and nothing's happened. Maybe they closed that loophole?

          • Steve Williamson

            I get the impression they have limited it location wise as well. dont think anyone in uk has had a ota for n4 yet... unless someone can prove me wrong

        • Simon Belmont

          I've tried clearing the Google Services Framework before on other devices. It might work, but it also caused weird issues with me having to log into my Google account again.

          I didn't really like that. I'd either wait for the OTA (which you surely have by now) or flash the factory image via ADB and fastboot (which, really, is easier than it sounds).

  • TylerChappell

    Woohoo! Ill be able to put a little bit of life back into my dad's old Verizon GNex.

    • Leo209

      Verizon Gnex? Sorry, that phone probably won't get the 4.3 update for months. That phone gets its updates from Verizon not directly from Google like the unlocked version does.

      • Mike

        The binaries are already released for it, all he needs is source and he is good to go. No need to worry about Verizon in this instance.

        • TylerChappell

          Exactly, Idk wtf leo was moronically thinking. Of course I am going to flash it myself, what a freaking nitwit.

          • Alan Shearer

            I think he forgot or did not know with the binaries you can create your own rom and flash it. Not really that hard.

  • http://www.buttie.pl/ buttie

    Wow, that was quick. Images, binaries and sources at the same time to almost all devices. Nice move Google.

  • zanoniguilherme

    The sad part for me: Basically everything that is new in this version is already on CyanogenMod 10.1.2 :/

    • skitchbeatz

      there are reportedly under the hood performance improvements.. so there's that.

      • zanoniguilherme

        Yeah... meh. CM is much faster than the stock ROM, so, there were under the hood improvements on CyanogenMod too. But, let's see!

        • Simon Belmont

          Android 4.3 is supposed to reduce the hits on the GPU by almost half, so that should be a significant boost in smoothness. As a bonus that helps battery efficiency.

          They talked about the GPU and graphics smoothness in a workshop at Google I/O 2013. I'm guessing those improvements, at least in part, are what is in Android 4.3.

          • zanoniguilherme

            Oh, that's interesting! Will be even MORE amazing when the people of CM starts working on it :)

          • Simon Belmont

            Exactly! My B&N Nook Color and HP TouchPad await.

            If anything, it will be a boon to older devices like the ones I just mentioned. Gotta love improvements under the hood!

          • Björn Lundén

            Right, I had forgotten about that presentation.

            This is the presentation if other people are interested:


        • HoboJerky

          It's not much faster... I've used both recently on the same device. They are the same in terms of speed. CM of course has those extra goodies that we love.

  • oktnxbai

    Where's my OTA?! :D

  • mlj11

    Can I just say... I'd fly Google Airlines any day of the week.

    • Kormakur Danielsson

      It would be, by far the best airline, fastest flights, every seat is club class. Only problem is: your flight might get delayed from may to july.

  • Andy

    super excited :D

  • Simon Belmont

    Haha! I loved JBQ's airport/airline description of Android 4.3.

    It sounds like they did work on the smoothness (advancement of Project Butter), and battery efficiency. Go, Google!

  • Sfera Dev

    We are working on it also! #StayParanoid


  • rkb

    When OTA will be released?

    • pfmiller


  • Andrew H. Eliason

    Is there any chance that someone might work a 4.3 for upgrade for Samsung Galaxy tab 2.7.0? Or is that simply not possible? If it is, what is the best way to keep informed? Thanx.

      Try keeping an eye on RootzWiki or XDA.

  • mechapathy

    Not sure if you guys at AP saw it yet, but the full, official changelog has been posted. http://developer.android.com/about/versions/jelly-bean.html

      Thanks, just what I was looking for!

  • Adil Qamar

    I want it to be rolled out already! OG NEXUS 7
