Flashable Jelly Bean JRO03O Zip Now Available for Galaxy Nexus LTE

As most of our Galaxy Nexus LTE owners know, a test Jelly Bean build was found last night and released this morning for you all to enjoy. If you didn’t feel like factory imaging back to stock Android 4.0.4 (IMM76K), so that you could then update to IMM76Q and then eventually onto JRO03O (Android 4.1), you were much more patient than I. That patience has paid off, as a .zip that should take you onto JRO03O from any ROM has been released by @P3Droid. 

Download:  update_jro03o.zip [mirror]


*If you only want the new radios from this Jelly Bean build, you can find them here.

1.  Download the file from above onto your phone’s storage.
2.  Reboot into recovery and make a backup.
3.  You should probably wipe data and cache at this point.
4.  Then “install zip from sdcard” and find the file you just downloaded.
5.  Watch it install, reboot, and enjoy.

If you run into any issues, be sure to let us know in the comments. And again, be sure to make a backup first.

*The build is stock, but has been rooted.

  • misterperson

    Does my phone need to be rooted before I flash jro03o? I have IMM76K.

  • I need help with this.I followed directions to the t.and I still can’t find the file.please help..

  • I’m having trouble doin this.I put it on the SD card.still can’t find it.very frustrating.

  • MC1220

    can you install this from 4.0.4 unrooted ? also will I still receive the official OTA for jelly bean when it finally does come out after installing this?

  • Michael LoCastro

    It now looks like my software keys are completly gone … need some help please .

  • Can someone help me out? When I try to install from recovery mode, it says the installation was aborted.

  • Alan

    The post says the build is stock but rooted however when I installed it I lost root. I regained it by using the galaxy nexus toolkit. Just a heads up though…I did lose the use of my franco kernel and overclocking.

  • spickle

    you don’t have to wipe anything, once you install zip from SD card and reboot it serves as an update and you’re fine. i call it installing it dirty. (as long as you were already on 4.1 before going to 4.1.1)

    • I followed the directions.I still can’t find the file.

  • Devon Forgea

    Stupid question, but after I flashed this and rooted, the default messaging app notifications do not work.I use Handcent for the most part, but I want to try the new expanded notifications. I looked all over XDA to no avail. Any thoughts?

  • Tristan

    Well, i downloaded it and it worked it took twice to do it but im running jelly bean and its running real smooth can’t argue about it, i think it’s better than the gs3 no lag whatsoever an on top of the nova launcher launcher it’s. Gorgeous

  • Scottosaurus

    Used the mirror site and the download was very fast! Incredibly happy with the ROM so far!

  • I am not rooted anymore!! I wanna be rooted but I don’t wanna deleted anything. My plan was to use this till Verizon announced the official update, then I would update to 4.1.x ! I need help seriously !! Please help me ! I don’t know what to do ! Or will I just have to flash the stock jellybean bootloader and I will be all good, so I don’t have to go back to 4.0.4?

  • Counsel Dew

    Does this fix the mid-call muting issue? See http://code.google.com/p/android/issues/detail?id=24019

  • Nic

    Will I be able to update with the official Jelly Bean Rom when it is released from verizon even if I put this rom on my phone?

  • amtraq97

    Do i need to be unlocked for this?

  • Is it just me, or did battery life on the Verizon Galaxy Nexus absolutely tank when I went from 4.0.4 to 4.1.1. i’m lucky to get maybe 4 hours of battery life before I get warning messages.

    • Micah

      Do you happen to be using Swiftkey keyboard? I had the same battery issue when I went from 4.0.4 to 4.1.1, uninstalled Swiftkey and now i’m getting a full day of battery.

  • tk25

    Can anyone explain to me the difference between 4.1 and 4.1.1? I’ve tried searching the Internets but couldn’t find an answer. Thanks.

  • mz

    Does this come with the JB Bootloader? I’m still on a ICS Bootloader with the latest AOKP JB nightly.

  • Mark F

    does anyone know how i can get Google wallet back on after this ?

  • kfath1978

    i cant get the download to complete. i have tried several times too… also does this unroot? if so what is the work around?

  • spickle

    tried downloading it on my phone and got UI errors and i had to reboot. soo 55 mins left, yay… :

  • Besides the radios, is there any benefit to flashing this over AOKP 1? I love my baked-in notification toggles and battery percentage in the status bar. Also, will I not be able to use the stock wireless hot spot feature with the official VZW zip??

    • TK25

      Yes, this will disable your hotspot AND unroot your phone.

      • Mark F

        What agreement are you on ? I have family share

        • TK25

          Family plan: share the minutes, but I have unlimited data (grandfathered) and 500 texts.

          • Mark F

            I can still get hotspot. Then again I’m not on unlimited.

          • Mark F

            I can still get hotspot. Then again I’m not on unlimited.

          • Mark F

            I can still get hotspot. Then again I’m not on unlimited.

  • xXAaronSXx

    Been using Bugless Beast Nightlies and honestly have no interest in switching. Especially if I have to wipe. CM10 may get me to switch eventually, but I’m lovin’ this rom.

  • JoeTi

    FYI, this made me lose root. All I had to do was flash the su binanry only file through recovery and I was back in business. File at: http://androidsu.com/superuser/

  • JoshGroff

    I almost cared, but then I remembered AOKP has a JB ROM out.

  • Teddy O

    The upgrade went very well for me (Coming from Vicious V1). My nexus runs alot smoother with this version. I was able to get root back by installing
    Superuser-3.1.3-arm-signed.zip after installing the update. It can be found athttp://androidsu.com/superuser…

  • TK25

    Suck! It takes away root access after install. I’m going back to Vicious.

  • mudleyblind

    Yeah there’s traffic, which is my least concern, but WTF does it say in the decoding text box? I never understand that Sh*t!

  • mudleyblind

    This is good but what about gapps?

  • jim

    i gave up a few days ago and rooted,should have done it sooner

  • Rooted ZIP w/Trinity Kernel located here: http://goo.im/devs/ThunderStick/Toro

  • Marshall Taylor

    I flashed and lost root. Is there a method for getting it back?

    • http://androidsu.com/superuser/

      Might be a few seconds late but download the SU binary file under ARM devices…boot into recovery, flash the binaries, reboot and then update the binaries using SuperSU and you’ll be golden.

  • I had to remove my torrent link because it was confirmed that my file will cause root to be lost. I’m waiting for the rooted ZIP file to be available and I will create a new torrent to share.

  • Atvse

    So my bootloader is unlocked but I’m not rooted. Do i just copy and paste this into my phone and then recovery mode. Then done? Or do I need to be rooted?

    • You don’t need to be rooted. After you apply the ZIP in ClockworkMod (or other) recovery, you will need to wipe data and cache so make sure you’ve run a backup first.

  • Me Myself and Somebody Else

    Does anyone know if there are release notes? I’ve got JRO03C (Bugless Beast) and I’d like to know if it’s worth the effort to downgrade so I can update. Any big difference between C and O releases?

    • There won’t be any release notes. I’m on BB myself and I’m sticking with it until Pete updates BB. I haven’t flashed the new radios yet but that’s the only thing I would update if I were you.

      If you need the files, you can download the torrent here: http://kat.ph/vzw-gnex-jro03o-update-t6617305.html

      • bh

        I flashed radios today on newest BB – extra smooth !!

  • Peter Stover

    Does this come with chrome as the stock browser?

  • This update loses root. Can anyone else confirm?

    • All OTA updates will cause you to lose root unless you have saved your root via RootKeeper.

  • Torrent created. Enjoy! 🙂 http://kat.ph/vzw-gnex-jro03o-update-t6617305.html

    Edit: This is the Rooted ZIP file and the Radio ZIP file.

  • JoshGroff

    Nice, after I get a cheap one that someone bricked and get it up and running, I see this article. Can this day get any better?

  • kfath1978

    I think Verizon will push this out before the download completes!! S l o w !!!!

    • jim

      go bucks

      • Mike Menard


        • jim


  • johnc7995

    Been downloading this for 45 minutes, can someone mirror this to a faster site please?

  • fritzo

    just checked my stock GNEX, im still on IMM76K. So i can’t use this update unless im on IMM76Q? any idea when the OTA update might be pushed?

    • Since IMM76Q and JRO03O are test builds, it could be awhile.

  • Maansova

    Is this only for rooted users?

  • Q

    No mirror?

  • Hmm.. To make the full jump from AOKP JB, or flash just new radios, or Let my phone enjoy itself for a few days without tinkering?

  • Buckoman

    This is going to sound stupid, and I know I know this, but does the phone have to be rooted, or does it not considering this is a signed zip?

    Can’t I just do this from Android system recovery ?

    • Phone does not have to be rooted, but you do have to use a third party recovery like Clockworkmod and you should wipe data/cache, so make sure you have a backup.

      • Buckoman

        To install a custom recovery, I’m guessing the bootloader has to be unlocked though, yes?

  • wickets

    LOL, 2 days for a download!! Yikes

  • Tyler

    So … anyone find a mirror? 20hrs doesn’t work for me.

    • sru571

      seriously, this needs to be torrented

      • gorkon

        Amen to that…..torrents or more mirrors….

        • Tyler

          I agree that would have been a lot quicker but my hour long download is done.

    • Tyler

      Found what i think is the update file from p3droid tweet.
      here is link: http://t.co/vKnqq0Dz

  • jmac

    Any word if/when the navigation bar will go back to the bottom of the phone?

  • rmp20

    Can anybody confirm if Bluetooth dialing is working properly on this build? I’m on BB (and ran some others before) and Bluetooth dialing was completely broken and useless. It constantly picked the wrong names and misheard everything.

  • Maui

    does this include the new bootloader?

  • TowelieMeBanana

    I’m stock and want JB asap. Should I do this? Can I? Would I need to wipe? Thanks much.

    • for sure if you want jb asap why not

    • desiman26

      If you’re rooted, you can just flash the zip above in CWM.

    • Yes you have to wipe and start from scratch. Google Play will keep a record of all your downloaded programs and gmail will keep all your contacts, so you can reconstruct your info I always video my home screens and folders with their contents before wiping, so I can reconstruct what I’ve created in the prior version.

  • TowelieMeBanana

    I’m stock and want JB. Should i do this? Can I do it without wiping?

    • Josh Flowers

      rooted stock? or just stock?
      as for wiping–step 2) “you should probably wipe data and cache at this point.”

      • TowelieMeBanana

        Unrooted stock.

        • Josh Flowers

          this post is specifically for a rooted user with a custom Recovery (ie ClockWorkMod or TeamWinRecoveryProject installed, via the file can be flashed & data can be wiped).
          in order to root, search for “Wugs Tool Kit” & it’s a fairly easy process. start to finish is about 15 minutes, once drivers are installed (with on screen-computer instructions the entire time)

  • im no noob with falshing i been rooted for some time but im confused what makes this so special of a rom we have had jb roms out for a few months now? thanks

    • This one is blessed by Verizon Wireless (most likely contains performance fixes and enhancements, custom to the device) and contains new radios. Though the radios can be downloaded and installed seperately.

      • ha i appreciate the explanation the only problem is im not expert but verizon “approved” updates have not had the greatest track record leading me to feel that maybe best to just hang on to my sorcery 2.1 rom which i cant find a thing wrong with

    • Josh Flowers

      ROMs out there have been created from the GSM GNex’s JB build from Google I/O
      (with corresponding kernels)–this is the first (supposed) Verizon JB with software that should interact correctly with all portions of the phone because of a Samsung Kernel
      (please correct/add if wrong)

      • Most community ROM’s out now have been built from the AOSP source from Google. Only very-early stage JB ROM’s were built from the GSM Google I/O build.

  • Mark F

    Same here

  • jcorf

    Does this version have unified search?

  • jim

    if this isnt the final update build,why do it?

    • duke69111

      Because so far, its the latest and greatest and we have to fill our curiosity.

      Oh and Why Not. 🙂

    • EC8CH


      This… is…. NEXUS!

  • Stephen Gaskins Jr.

    10 hours left on my download. I guess I am not the only one who wants this….

  • Hmm, very interesting.

    Phone Search seems to be completely operational in JRO03O, not dumbed down at all from IMM76Q. I was able to search through my Contacts using Google Search after it synced with my Google account.

    I haven’t loaded up any music on my device yet, so I haven’t had the opportunity to see if it actually searches. But going into Options in Google Search, I do see options to search various internal sources such as Google Videos and Google Music.

    • Confirmed. Unified Search is fully functional in JRO03O.

  • md5?

    • And what is the file size?

      I have not flashed it yet, but that is what I got when I downloaded it.

  • JayTee

    That download link location isn’t very good. I’m sure there’s way too much traffic on it. Do you have a mirror site anywhere for it? It’s downloading slower then a 2400 bps modem. Thx!

  • Tim Swann

    Love how the download for this is taking SOOOOOOOO long. Can we crash this server too? lol

  • DanWazz

    Any word on if the radios make any difference and worth the flash?

    • CoCoCalypso


    • summit1986

      Havent noticed any difference for better or worse… Flashed just the radios over AOKP JB Build 1

      • KreeTerry

        I did the same, i noticed it takes a little longer to get a connection on boot but the 3g to 4g hand off seems to be a little smoother. and idle battery drain on 4g is a lot better. Havent noticed any changes in speed over the old radios though.

    • I just know that it’s the first VZW radio update since JB was released. The previous radios (04/05) were intended for ICS.

      Personally for me,

      I find the device overall snappier for some reason. Most likely placebo effect though.

    • Booyah

      Flashed them this morning. I’m at work and have always got great 4G here. No different with new radios. I can tell you that they aren’t any worse. True test will be at home where I get one bar.

      • ndog21

        I also have only 1 bar at home with the new radios I get 3 bars

    • Cam

      Zero change here. Checked signal before and after (only flashed the radios).

    • Jake

      I used to lose signal every 30 – 60 minutes, even here at the office, where I have a solid four-bar signal strength. I’d go from four bars to suddenly no signal. I flashed the new radios (I’m running Bugless Beast) around 11:30 AM today and haven’t had a single loss of signal in the 5.5 hours since then. Around noon I did a speed test and got 26.09Mbps down and 12.96Mbps up. My LTE was fast before, but not that fast. My latest test are averaging 18-19Mbps down and 12-13Mbps up, which is still fast.

      • hey jake im on same rom Bugless beast and i have same signal problem. how do i get the radios?

    • It somewhat improve a little, but that’s depending of where you are, and will need more testing here…

    • famester

      Mines overall faster speed tests went up too. But everything loads quicker for me.

    • Jimmy Hogoboom

      Ever since Verizon turned on 4g in my town, I’ve had the worst time with my GNex. Every 10-20 minutes it would completely drop the cell signal, and then spend another minute or so turning back on and connecting again.

      Since flashing these new radios, it hasn’t dropped once. Not one single time. It’s been absolutely beautiful.

    • JoeTi

      It seems there is less battery drain in 3G with both 3G and 4G radios on. About 2 to 3 percent less per hour in my case. It’s small but could make a big difference after 5-6 hours.

  • Any word on the new radios? Improvements?

    • MichaelFranz

      it will vary, some people yes, some no, others dont see any. I saw a slight signal boost at my desk here at work on LTE. my speed scores were up 2-3MB/s and my signal strentgh was boosted just slightly. again thats only at work havent check it anywhere else really.

      • Thanks. I’m fine with BB, but if I can flash new radios over it w/o wiping data, might as well give it a shot to improve LTE.

        • MichaelFranz

          yea you can flahs them without wiping data. The link over at Rootz has the 4.0.4 ones as well in case they dont work out for you

  • strows


  • Wait so I need root to do this? I’ve been out of the game for a while

    • Tim Swann

      no, but you have to have an unlocked bootloader. You can boot a temp CWM recovery, perform the backup and then flash this.

  • Stephen Gaskins Jr.

    Might be a dumb question, but are the new radios included in the .zip?

    • Tim Swann

      most likely not, but there is a flashable zip with them anyway so the extra step shouldn’t be an issue

      • moelsen8

        i would’ve guessed the opposite. but i guess we’ll never know until the download finished, 3 hours and change from now. haha.

        • Tim Swann


    • Yes, they should be.

  • potacho

    Is there any way to update without wiping data? There was a way to do it for 4.0.4 and I’d rather not have to wipe.

  • bean

    why do we need to wipe data and cache?

    • Black Roger

      Just do it!

      • summit1986

        Easy there, Heisenberg

      • SKAVENG3R

        What up black? Let me ask you something off topic… when in backup what does wipe battery cashe do??


    • Tim Swann

      it’s always safe to wipe before flashing anything. If you don’t want to wipe, wait for the official update, or find a way to get on IMM76Q and then proceed by using the update.zip

    • Cause its always a good idea

    • You should always wipe data and cache when jumping ROM’s.

      • potacho

        What if you’re not on a ROM?

        • disqus_IHpm8UzFns

          Then your phone is def not working now! Jk. You just mean to ask what if you’re not on a custom ROM. Any software on your phone would be the stock ROM. Think of a ROM as another word for custom software packages. If you’re still stock you need to unlock boot loader, root, flash a custom recovery , and flash this. Although it sounds like a lot, just Google gnex toolkit , and you should be good from there.

    • desiman26

      It’ll make things go better and smoother. If you don’t wipe it, you may still have the files from the old os. When mixing the old os with the new custom os, good things just don’t happen.

  • rk

    Could someone clear up a confusion for me? Has IMM76Q been released as OTA update from VZW? Thanks.

    • moelsen8

      i’ve also been wondering if this was ever actually pushed out to the masses or not

      • Tim Swann

        see above

      • T Hall

        I don’t think it was ever pushed out to the masses. I have it just because that is the way my phone came.

      • KleenDroid

        If it had been pushed out to the masses the masses would have it.

    • No, it has not.

      • michael arazan

        My brother just got a refurbished Gnex from vzw from his old one getting wet, his does not have the Q update either

      • heechlim

        I got a replacement not 3 days ago with the Q update

    • Tim Swann

      Has not been released officially. It’s been coming pre-loaded on replacement devices though.
