Download: Verizon Moto X Kit Kat Update Build 140.45.5

moto x kit kat update verizon

The Verizon Moto X’s Android 4.4 “Kit Kat” update is rolling out as I type this to a number of devices. Motorola told us that the rollout was staged, but we were able to pull it immediately once it went live, along with many of you. In fact, we’ve already done a hands-on video with it and showed you how to get Google Wallet Tap & pay up and running. But if for some reason you weren’t a part of that initial push and are stuck waiting for the update to arrive, we have the file for you to sideload thanks to @P3droid.

You’ll have to be stock, unrooted in order to flash this file through the stock recovery. 


*Note – I have not personally flashed this file as my VZW Moto X received the update OTA. If you choose to do so, you do so at your own risk.

1.  Download the update file to your phone’s storage. [Download Link]

*Yes, the file is named 139.15.1 because that’s how Motorola update files work. They name them with the build number you are currently on. Once updated, you will be on build 140.45.5.

2.  Once downloaded to your phone, power it off.
3.  Boot to recovery by holding Power + Volume Down for a few seconds. Let go.
4.  Once the Fastboot screen loads, hit Volume Down to highlight “Recovery,” tap Volume Up to select it.
5.  A green Android should appear. Tap Power and Volume Up slightly to enter recovery.
6.  Choose “apply update from sdcard” by hitting Volume Down to highlight, Power to select.
7.  Find the file you downloaded to your internal storage.
8.  Highlight it using Volume Down, select it with Power.
9.  Watch your phone update.
10.  Reboot and enjoy!

    Download link is dead…

    The build date is November 12. That is a fast turn around for testing and deploying. I’m surprised actually. This isn’t a build that’s been sitting around for a few months. It’s barely over a week old.

  • skzion

    Um, who cares about the Moto X (excluding those who are paid to be fanbois)?

    Nexus 5 still awaits a review here. The delay has become comical.

  • Skittlez

    which build is this. cause people are saying, “oh not even all the nexus devices didn’t get KK yet.” but apparently they pulled the update and are putting out another build with bug fixes. is this the new build, or the original KK build

  • Christopher Ford

    I just did the ol’ Check for Updates thing and it started downloading the OTA!

  • Pat Leck

    Cool update. http://bit.ly/1aFaPfV

  • Nick Silver

    I am getting a “file not found” when clicking the download link.

  • Brien Gerber

    Anyone find a work around for the dialer that will search local businesses?

  • dylan84

    This has gotta be a record for update turnaround. Three weeks after KitKat is released and already out on a non-Nexus and non-GPE phone.

  • Chad

    Not liking the update at all. Phone feels a lot more sluggish. Especially the new slow screen off animation. Just because it’s a new update doesn’t mean it’s good or beneficial.

    • Jacwhite22

      I’m not getting that at all…..but I also did a factory reset (rsd lite) with mine.

  • Shane Redman

    Just waiting for @Kellex to change the title of the post to “……(Updated: Works for Droid family as well!)”

    …but I think i’ll just go to bed

  • C-Law

    Anyone know how long it might take for the entire vzw 4.4 firmware to show up on sbf.droid-developers.org?

  • DJ SPY

    Funny, my 2013 Nexus7 is still waiting for KitKat.

  • Tom Luley

    How about if you already have root? I dont mind losing root for awhile, but I want KitKat! I tried flashing it in custom recovery, no dice.

    • Jeremy Wray

      sbf back to stock or flash the stock recovery through adb

  • Sean Bello

    the world is ending

  • jamaall

    one can only hope that the droids will also get the update in the next week… especially since they are exactly the same with different screens and batteries.

  • Richard Giordano

    Will this work for the droids too?

    • Jeremy Wray

      eventually when moto releases the updates in a few weeks

  • Chuck Mangione

    Droid Maxx? I assume these phones are to different for this update?

    • Adam Truelove

      To different or not to different?

    • Jeremy Wray

      While very similar, they are different. But your update should be only a few weeks away, if even.

  • LiterofCola

    *patiently waits as I stroke my Droid Maxx*

    • easting

      slowbating will get you nothing.

      • michael arazan

        Be careful, a boy in Brazil died from doing it 42 times in a row, no joke.

  • Michael Contreras

    I should have gotten the Moto X unlocked :/

  • Just got the update !!!!!!

  • PhilD41

    As several have alluded to below… has anyone be able to re-root once updated to KitKat. 4.4 is awesome, but worthless if I loose root!

    • George Fayad

      Best bet is to hop on XDA or wait until something is made public here.

    • Jeremy Wray

      4.4 was already rooted for the at&t update (assuming the test build becomes official) so once the other carriers get their updates the new root method will be released.

  • Timothy McGovern

    When will the LG G2 get 4.4?

    • grandautotheft5

      in 4-6 months

    • Adam Truelove

      Well first LG has to mess it all up, then Verizon has to approve it. So yeah, sometime mid next year.

    • Jeremy Wray

      Yours will get it once you root it, unlock the bootloader, and install some cyanogenmod on it (once cm11 becomes official that is)

    • Jacwhite22

      Mid 2014.

  • CyHawk60

    A Verizon phone get Kit Kat before my 2013 Nexus 7?!?! Dogs and cats living together!! We’re talking mass HYSTERIA!!!

    • Adam Truelove

      human sacrifice

    • I was just about to make the same complaint!

    • William_Morris

      40 years of darkness, earthquakes, volcanoes! The dead rising from the grave.

      • michael arazan

        Motorola and Google crossed the streams!

  • George Fayad

    This goes without saying, but for the uneducated:


    • Mike B

      And Ill also add…


      • George Fayad

        Plus one. Although, i didn’t bother un-rooting or anything and it installed fine. but i was using the old root method that doesn’t freeze the system.

        (MotoRoot 1.1 or some such app)

        • Mike B

          I read that this update wipes system so maybe that’s why it still worked but stock recovery is needed to flash.

          • Jeremy Wray

            You lose root no matter what because it wipes the whole system but originally Rooting the Moto X did not turn off signature check and remove the recovery. Technically on the newer ones all you would have to do is replace the stock recovery and boot image files.

      • YMMV: Mine needed to have Xposed removed and stock recovery to flash, no unroot (VZW Moto X Dev edition)

    • tyguy829

      has anyone tried re-rooting with rockmymoto after updating?

      • George Fayad

        I personally have not. I tried MotoRoot 1.1 purely because it was already installed on my phone. It didn’t work, but I didn’t expect it to since it was confirmed not to work with the latest “camera fix” update.

        I plan on visiting XDA in my free time and following the progress over there.

        Edit: also, Voodoo OTA RootKeeper obviously didn’t work, since i was trying to re-root my phone.
        Not a big deal for me. root gives me a functional reboot button, adBlock, and Root Explorer. These are all things i don’t necessarily need on a day-to-day basis.

        • Jeremy Wray

          4.4 was already rooted for the at&t update (assuming the test build becomes official) so once the other carriers get their updates the new root method will be released.

        • tyguy829

          i need root for tethering. have you found another solution?

      • Jack3D

        I can’t even update to the OTA with rockmymoto.

        Even after wiping dalvik and flashing stock recovery, it says “Update Failed”.

        {Sad face}

        • tyguy829

          oh damn so we’re going to have to rsd lite first? That’s good to know. Also, i was talking about trying to root with rockmymoto after updating

          • Jack3D

            Understood, I just wanted to comment on my experience. However, I am going to try it by removing root first…if I can.

          • jeff manning

            I would flash recovery manually instead of RSDLite. All you have to do is flash recovery and the system.img and you won’t wipe your data. If running Windows 8 or later you will have to use mfastboot instead of regular fastboot. You can find it on xda

          • Jack3D

            I’m getting PIV errors when trying to flash the system.img I have. Where did you get your mfastboot file and system.img?

          • jeff manning
        • I had to fastboot flash system.IMG and recovery.IMG

          • derbo904

            I fastboot system and recovery and installed with no issues.

          • Jack3D

            How did you do this and where did you get the system.img.

            I’m getting PIV block validation for system failed. Invalid PIV image. Not sure where to go next.

          • derbo904

            google mfastboot. There is a different fastboot that allows you to copy the system.img over.

          • Jack3D

            I did try it, but still get the PIV issue. I think my system.img is not good. Can you point me to the one you used?

          • derbo904


            download the verizon 57 one and unrar.

          • Jack3D

            Well, I was able to flash verizon 57, but still unable to install OTA. Think I’ll just have to factory wipe and try again later.

            Thank for the help.

          • derbo904

            That is weird. I flashed just the system and recovery and was able to run it. Good Luck!

          • Jack3D

            I ended up having to RSDLite back to stock to get it.

            I don’t know how that went bad…oh well. Thank god for Helium backup!

        4.4 was already rooted for the at&t update (assuming the test build becomes official) so once the other carriers get their updates the new root method will be released. fingers crossed
