Android 4.4.1 continues to wind its way through the air, hitting devices a few at a time. Being a smart young individual, you know you don't need to wait for the OTA to reach your device in the old fashioned way – you can skip the line. The OTA update file for the WiFi version of the new Nexus 7 (that's Flo) has been spotted and we've got it right here for you.

Disclaimer: Android Police isn't responsible for any harm to your device - proceed at your own risk.


To get this update installed correctly you need to have the Android SDK installed and working on your computer with ADB (via a microUSB cable). This is what allows you to issue commands to your device in order to push the OTA file. Those with custom recoveries have it a bit easier, though. You also have to be running the stock Nexus 7 ROM, version KRT16S.

If you have made any system file modifications, make sure you roll them back.

Before you get started: This update method should not erase anything on your device, but back up as best you can.

You'll use the adb sideload command after making sure your device is properly detected by ADB. You can check out our full sideload guide here – the process is identical except for the file name. If you have a custom recovery, it can be flashed from there. Just copy the file.


The update will likely kill root on previously rooted devices, but it's easy to get back:

  1. Flash TWRP from here (fastboot flash recovery FILENAME.img).
  2. Reboot into recovery (adb reboot recovery or hold Power+VolDn, then select Recovery).
  3. Flash the latest version of SuperSU.
  4. You should be rooted.

    Done. Thanks!

  • Marshall Villanueva

    I don't think that's the correct md5sum.

    • Andrew

      Yeah, I got ce344ae6d5d2f74f80c9009947c9cbe9 when I checked it.

    • RyanWhitwam

      Yep, fixed now.

  • Hipster Dashie

    Will the 4.4.1 OTA unroot my device? What would be the best way of keeping it, short of re-rooting it after the update?

    • Sorian

      When I want from KRT16O to KRT16S, it didn't mess with root (N7 2012).

    • brkshr

      It will unroot your device. Just like the article states, you should re-install a custom recovery and flash SuperSU.

      • Ano

        Instead of commando 'flash' one can choose 'boot' TWRP. Keeping stock recovery that way while temperary load and use TWRP.

        • fzammetti

          Yeah, definitely, I thought that flashing custom recovery permanently was an odd suggestion since there's a good chance that stops the next OTA from working. Temporary for sure... also, using Wug's toolkit isn't a bad idea... makes it all a bit easier and idiot-proof :)

        • brkshr

          Didn't know that. Thanks

      • Hipster Dashie

        Ah, that sucks.

        In that case, I suppose I'll just re-unlock my bootloader before updating, so I can re-root using Wug's toolkit without having to wipe. Thanks for the heads up. :)

        • brkshr

          There is a post above here (pasted below now) that said he turned on "survival mode" in SuperSU and it worked. I haven't tried it, but maybe it works. Might want to check the forums first.

          "FYI, I just installed it *WITH* survival mode enabled and the update was successful and I DID NOT lose root. Now, I did take an su update in SuperSU just before, and it's the latest version of SuperSU, so maybe that makes a difference, but for me, no problem. Stock ROM and recovery for me BTW."

  • RantGirlRants

    I'm just really really hoping it doesn't take as long as the initial Kitkat rollout did for the OTA.

    • Michael Pahl

      you don't see the download links above?

      • RantGirlRants

        I meant actually receiving the update via OTA rather than sideloading. Sigh.

        (I know you knew that. Why do I feed the trolls...)

        • Michael Pahl

          That's like complaining the guy in front of you is driving too slow, but the passing lane is wide open.

  • alex

    what does this version have over 4.4

  • Simon Belmont

    *Waits patiently for Nexus 7 (2012)* Just got the OTA to Android 4.4 a week ago on that.

    This time, I'll probably just sideload. Can anyone confirm if the lockscreen gains transparency in the navigation and notification bars like the Nexus 4 did?

    • Ryuuie

      I can confirm it does, yes.

      • Simon Belmont

        This is good news. It means Google is probably getting ready to put GEL into the Google Play Store.

        See, the lock screen needs a separate update from GEL to get the transparency to work. So now that it's uniform transparency between the lock screen and if GEL were there, there's no reason not to release it.

  • MacMan156

    Anyone know if it matters if you are in ART mode or davlik when you sideload?

    • reneMAC

      it does not matter.

  • fzammetti

    FYI, I just installed it *WITH* survival mode enabled and the update was successful and I DID NOT lose root. Now, I did take an su update in SuperSU just before, and it's the latest version of SuperSU, so maybe that makes a difference, but for me, no problem. Stock ROM and recovery for me BTW.

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

      Chainfire fixed it. We need to remove this from instructions.

    • Pat Simeon

      Did you upgrade through OTA or did you sideload it? I'm getting impatient so yeah, lol.

      • fzammetti

        Sideload (sideloaded the OTA file to be specific)

  • kh5

    Weird. I had to use stock recovery to flash this. In TWRP and CWM it always said that my device was a deb and this update was only for flo. (I have a flo, it's showing correctly in the bootloader, so I don't know what went wrong there.)

  • Adi-Karta Dasa

    Not working for me. Status 7 installation aborted.
    Any advices?
    Thanks in advance.

    • Tomen8r

      Receiving status 7 errors as well on Nexus 7 2013. Tried a bunch of tricks found online to no avail. Frustrating.

  • Aravind J Nampoothiry

    When flashing it says system/bin/thermals has unexpected contents.I am on elementals kernel and is over clocked a little.

  • anmolm97

    Can't I temporarily boot a custom recovery "fastboot boot recovery twrp.zip" on a locked bootloader and obtain root?

  • plastic101

    Any idea where one could find 4.4.1 for the 2012 N7 WIFI?

  • Daniel Melo

    i dont know what to do please help

    • Warren Marshall

      Flash stock system.img and stock boot.img
      Flash OTA
      Can be flashed with latest TWRP recovery

  • robett

    Hey Ryan I am a little confused. My nexus 7.2 tablet does not show the update for _4.4. Is there still a wait for the OTA update or is there some reason I am not receiving the update. Should I just manually download Or just do a factory reset. Thanks
