Good news, ROM enthusiasts: the Android Open Kang Project has released the much-anticipated first build of 4.2. Bad news: it's a completely new ROM, built from the ground up. That means that it won't be quite as feature-packed as you remembered, and device support is limited to the more popular Nexus models, at least for now. You'll also need to install a recovery that's compatible with 4.2 ROMs (the latest ClockworkMod and TWRP should do the trick) and do a full data wipe of your previous ROM. Warm up Titanium Backup.


For the MR1 release, only the Galaxy Nexus (Verizon and GSM flavors), Nexus 4 and Nexus 7 builds are available. On the bright side, most of the customization functions have already been brought over to the new builds, including customizable Navigation Bar targets and the like. The AOKP team even managed to cram a few new features in there, including unlimited lockscreen widgets, statusbar transparency, and fully customizable 4.2 statusbar toggles. The only real issue with the ROM so far is spotty support for the new multi-user function.

Downloads for the MR1 release and Gapps can be found at the link below. The next release, which should come in 2-3 weeks, will (hopefully) add support for the more prolific Galaxy phones.

    Second paragraph, I think you mean Nexus 7 not 10 :)

    • Jeremiah Rice

      Yup. Thank you for this wonderful naming scheme, Google.

    • Ed Baker

      I double checked that as well.. Darn! It's for the nexus 7(grouper), not for the nexus 10(manta)

  • http://twitter.com/snowfire88 Ravi

    Second paragraph, last line. I think you meant "New" multi-user function. It's "mew" right now. :)

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

      I liked "mew" better.

      • PhoenixPath

        No. They need to fix it right meow.

  • Scott

    I switched from AOKP to CM10 a while ago but thought I might jump back to AOKP now, since CM10.1 doesn't have a customizable Nav Bar yet. However, CM10.1 does have Notification widgets (in addition to Google's Quick Settings). Am I the only one who really prefers the widgets over Quick Settings? If this AOKP ROM had those I'd jump in a heartbeat. Most of what I want from a custom ROM is customizable Nav bar, custom notification widgets/toggles, and CPU controls.

    • http://twitter.com/romanbb Roman

      We'll be bringing ours from 4.1 back later, I believe

      • PhoenixPath

        Thank you, roman!

        We likes our toggles.

      • subaash

        It will be a pretty nice if AOKP has the expanded desktop function like the CM10 because it will an ease to play games or browse in a click..

        • kool_dude

          AOKP has it, I think it's called NavBar toggle under Power menu settings. It's been there since November IIRC.

      • Scott

        Perfect, if AOKP adds it first I think you win. Still running CM10.1 but I'll be keeping my eyes out for this addition - also - @kool_dude:disqus had a great point about the settings button being hidden in Quick Settings - another improvement that I really would like back from 4.1.

    • kool_dude

      I too prefer the notification widgets, but now the Settings button has disappeared & so I can't find a way to avoid Quick Settings :(. Anyone knows how to bring that button back ?

      • Scott

        Agreed, I hate having to open Quick Settings to access the Settings button. I want that back as well.

  • TechGuy21

    only 2 rom that doesnt tablet UI on my nexus 7. PA and jelly beer. cant try this since there no tablet UI.

    • Sean Baek

      Not in the MR1 build. However Stevenspear has a Jan 3 build with tab ui baked in. It's still in alpha, but functional. This build looks like they started over, so tab ui may take a little time to be put back in.

    #Hate Wiping data. :(

    • McLean Riley

      I'm sure devs who spend countless hours developing these roms care that you don't like to full wipe. In fact, you should complain more because they do. [/sarcasm]

      • http://twitter.com/misterE33 Mr E

        It's a fair complaint. I'm not saying the onus is on the rom devs, but if the wipe/flash process was less painful, more people would try out roms, and less people would try dirty flashing which can produce odd behavior and clog up forums.

        • http://twitter.com/rockstar_323 Kris

          How is it painful at all? I can wipe, flash, and restore (Titanium Backup is your friend) in like 15-20 min. Nowhere near as long as dirty flash, boot up with issues, complain on a forum, and re-flash the suggested way.

      • http://geniousatplay.blogspot.com/ Bikram Agarwal

        Do you understand the difference between "opinion" and "complain"? Look 'em up.

        I didn't say to "Boo-hoo..... make a non-wipe ROM". I just mentioned that I hate wiping data. If I have to, I will wipe data. Doesn't mean I have to love it. And if there's a version which doesn't need wipe (hypothetically), I'd rather use that. I think most people would rather use that.

        I'm a dev myself. Not ROMs but small apps. So, you don't have to remind me how devs spend hours on something.

    • Bariman43

      If you don't like wiping data you shouldn't have gotten in ROMs. If you want you can skip wiping data if you want your phone to be more unstable than a North Korean rocket launch.

      • Mike Harris

        That's like saying if you don't like waking up early, you shouldn't bother getting a job. C'mon now.

        • Bariman43

          Nice strawman. You always need to wipe data. Always. It's a fact of using ROMs. If you don't you'll risk making your phone woefully unstable.

          • kool_dude

            Just because you need to do something doesn't mean you have to like it.

          • Andy

            You don't always need to wipe data... I've had ParanoidAndroid for months, updating for the past few months until now without wiping data. I've had a problem *once* and all I needed to do was change one setting. Now, when PA built on 4.2 comes out, I'm going to make a backup and try to run without wiping data. Most likely I'll have to wipe, and I'm fine with that, but it's not always necessary.

          • http://twitter.com/rockstar_323 Kris

            You're right it isn't always necessary. Sometimes you can just wipe caches and format system and flash no problem. The real issue is the people who dirty flash and want help when there is a problem. If people have problems after a clean install devs can troubleshoot and fix the bug. If you dirty flash and have issues you don't know if it's a problem with the ROM you just flashed or something left over from not wiping.

    • Cherokee4Life

      I love it, its like a new phone each time! is that weird?

  • seeymore

    battery life sucks in aokp compared to cm 10.1

  • northstar

    I've been using the test builds for a month. Stable as hell on GSM GN. I use Franco kernel and battery life is 4 hours screen time heavy use.

  • Larizard

    got it running, let's see how battery life is...

  • http://www.facebook.com/profile.php?id=100000007203733 Anthony Nedumgottil

    Is there a way to change the system sounds? I miss the old stock sounds (i.e. pressing a nav button)

    • Tee

      Replacing the sound files with new ones will do.

  • Patrik

    Jelly Bean 4.2? No thanks

  • Bariman43

    Looks like the only features I used in AOKP 4.1 are right here in AOKP 4.2. Sweet, updating now.

  • PhoenixPath

    Been using Steve Spear's PUB build from Dec. 25th since...Dec 25th. Not really seeing anything in the list above that would necessitate a move from this highly optimized "preview" build.

    He made a new one for grouper yesterday. If he makes another for Toro I'll definitely consider it. Why fix something that isn't broken, eh?

  • Bariman43

    So far I'm noticing the Settings app goes a lot slower, Notification wallpapers don't actually work, and Nova Launcher likes to have a fit every one in a while. Besides that, for a first build it's pretty damn stable. Looking forward to the next one.

  • mrpendulum

    Does it still have the functionality where devs will defend a team member talking to users in a manner that only a self-important egotistical prat is capable of? Haven't touched this ROM with a 100ft pole after that incident, with no plans to ever again.

  • http://www.facebook.com/karim.kalschoven Karim Kalschoven

    Hahaha this morning i desided to do a full while on my GN installing a nightly.....and now they go official?....ironic!!!!
