Root Method Released for DROID RAZR HD Running Android 4.1.2, Other Devices Too

razr hd unlocked

Yesterday, Dan Rosenberg published the first Motorola bootloader unlock method in history. It was an epic moment for the rooting and development community on Android, as no one had been able to accomplish anything close to this for what seems like an eternity on a Motorola device since they started locking them down back in 2010. There was one problem though, the bootloader unlock worked on devices like the DROID RAZR HD, RAZR M, and Atrix HD as long as you were rooted before you updated to Android 4.1.2. For many of you, especially those with a RAZR HD or RAZR MAXX HD who received the most recent 4.1.2 update, you were out of luck. 

Well, Dan has returned again with another present – root for Android 4.1.2 and more. This method not only works on the RAZR HD, RAZR M and Atrix HD, but it should work on a variety of Motorola devices (until Moto patches it). So for those of you who were unable to unlock bootloaders yesterday, you now have the option to.

Keep in mind there is all sorts of risk involved, namely in relation to warranties. If you unlock the bootloader of your phone, your warranty is gone.

The instructions were posted up at DroidRzr.com, but we have included them below for you as well.


  1. Download this file to your PC.
  2. Extract the entire contents of the zip file.
  3. If you are using Windows, ensure you have installed the latest Motorola USB drivers available for your phone.
  4. Ensure USB Debugging mode is enabled on your device.
  5. If you are using Windows, navigate to the extracted directory and execute “run.bat”. If you are using Linux or OS X, navigate to the extracted directory in a terminal and execute “./run.sh”.

On a related note, Dan has announced that he is done trying to find exploits in Motorola devices as they have become increasingly difficult and time consuming. He urges you to consider your future purchasing decisions based upon the dev-friendliness of phones rather than waiting or expecting methods like his to be released by the community.

    does anyone have clear & easy steps for me to do this?
    Thanx in advance, joey

  • jim

    it did not work for me, i used another one . that one worked for me

    • deemo78

      Did not work for me either, what did you use Jim, may I ask? I have a Razr.

  • Nick

    Is there any way to “unroot?” I need to send my device in for warranty work and was wondering if this is possible Thanks

  • CptnRob

    Hello everyone, I have a Droid Razr original, refurbished under a best buy warranty. When I originally bought this phone over a year ago it was running on 2.3.6 and I used droidrazrroot. Worked fine and was able to unlock free mobile hot spot which is what I am trying to do now. So, I now have an original droid razr operating on android 4.1.2 and am unable to root it using this method. The root tools seem to install then I get this

    [*] Rooting phone…
    [+] This may take a few minutes…
    [-] Failure.
    [*] Cleaning up…
    [*] Exploit complete. Press enter to reboot and exit.

    Also, USB debugging is enabled and I just downloaded the most recent drivers for the phone.

    any help/advice would be greatly appreciated.


    • deemo78

      I have a Droid Razr too and I just rooted my phone and went in to enable free wi-fi
      with another link he had on the right side(good if you have unlimited data). So easy and it worked.

  • Andy

    Works like a charm on Asus tf300t 4.2.1

    Thanks 🙂

  • marlo.hude

    For some reason my phone is at 4.1.2. And my app store will not open no matter what I do…I have turned it off re booted it…..nothing idk if it has anything to do with it but I need helpzzzzz

  • Blake Moore

    What’s the point of having higher levels of access on your phone? What advantages/disadvantages does it bring to the user?

  • Completely fails at the “rooting” stage for a fresh factory RAZR MAXX. Tried numerous settings, no luck.

  • maxx hd

    How do I know if the root was successful?

  • userrazr m

    Everything installed have superuser but WiFi tether doesn’t work don’t know if its the app or if root didn’t root

  • leud

    ok root razr hd xt925 in brazil… success thankssss

  • 808BoOm

    will this work for my Motorola driod rzar maxx xt912

  • Nate513
  • That works on a XT925 device?

  • Khayo


  • airos4

    Just did it on my Razr M running 4.1.1 … worked like a charm where the motofail family didn’t. Motofail said that with the error I was getting, I should wipe data and try again – wasn’t willing to do that right now, but Motochopper worked great!

  • Tone

    Does it work for Droid 4 with 4.1.2 build?

    • wompshmack

      It didn’t work for me, but I’ll post here if I find something that does.

  • zmberven

    Has anyone had any luck with the OG RAZR/MAXX?

    • Lethalprophet

      Not I

      • zmberven

        Dukes! I figured it wouldn’t, but I was hopeful.

  • Morlok8k

    Motochopper rooted my Asus Transformer TF300T!

  • droiddan

    did not work,

  • This is exactly what i’ve been looking for. Thanks

  • PopeFrancis

    I thought he already stopped doing this stuff.. He said this before 😛

    Good work on this stuff Dan.. I’m sure many people thank you 🙂

  • DirtyDroidX


  • Tom Z

    Thank you so much… I’m now Rooted! Droid Razr HD Maxx…

  • Brandon Golway

    Damn, that was quick!

  • BJTemp

    YES!!! Been suffering for a month waiting for a root method. Plus, this was the easiest, quickest root ever! After downloading the files, rooted in 30 seconds. 30 SECONDS! Amazing! I can now tether to my heart’s content and Titanium Backup is once again one of my best friends! THANK YOU SOOOO MUCH DAN AND MAY THE FORCE BE WITH YOU. Your work will be sorely missed.

  • jojo4747

    Moto hates this guy by now

  • Michael Winner

    Amazing . Dan, where can I donate per the Root Bounty thread

    • Michael Winner

      Thank you so much, this works perfectly !!

  • Guest

    Works with Droid razr maxx hd no issues

  • schoat333

    No we just need a full working cm10.1 or AOKP build, and I’m happy.

  • EC8CH

    I’m kind of surprised by the lack of comments on these threads here at DL…

    Have the majority of readers here moved on from Moto?

    • duke69111

      I think you nailed it on the head. I thought the same thing.

    • Same here, I am pretty excited about this.

    • MichaelFranz

      ive been saying it a few times. I might actually pick up a Razr HD in exchange for my GS3 just because. And if i dont like it, then im stuck until July and August when I have 2 upgrades due 🙂

    • kixofmyg0t

      I for one don’t frequent the site as much. Most of the news just doesn’t apply to me because I have Moto devices. But this week has been exciting.

  • Im glad he decided to make this his last one, instead of just leaving the bootloader unlock and being like “you figure it out” Very happy with the turn of events from the last couple days.


    Still getting a root failure. Oh well. I guess I’ll have to wipe. Does anyone know of a way to backup without having root access?

  • Ryan

    Does other devices possibly include the og razr? And if so does that mean boot loader as well?

    • endurotech

      The OG RAZR is a flip phone

    • NorCalGuy

      Prob not boot loader because of is omap but I too am interested if it will root the RAZR

      • Lethalprophet

        I have the Razr, running official JB. This has not yet been able to root my device

    • jonny6pak

      “This method not only works on the RAZR HD, RAZR M and Atrix HD, but it should work on a variety of Motorola devices”

  • Mordecaidrake

    Probably a stupid question, but this will wipe my phone right?

    • I would imagine so, when you unlock a nexus it does a factory reset.

      • Mordecaidrake

        Correct, I’ve done it on my previous phone and N7, but just wanted to double check.

        • eck79

          Not correct, I unlocked last night and it did NOT affect the data of the phone. I have an N7 and agree that it wipes that device. Not so for this exploit, however.

          • Mordecaidrake

            Are you serious? This root/unlock method does not wipe the phone?!

          • eck79

            Definitely serious. I wouldn’t have done it late last night if it did. Run the script to unlock and boot right back into your phone just like you left it. Other than the boot image changing to the unlocked bootloader warning instead of the red/white M logo no data is touched.

      • Mark Mann

        rooting and unlocking are not synonymous…i rooted every phone i’ve ever had, and unless i changed roms, nothing happened to the phone…

    • Mike

      Wondering this too. My S3 didn’t require a factory reset…for root or bootloader unlock.

    • zmberven

      Rooting? No.

      • David Moylan

        so if i use this method to root, i lose nothing?

        • zmberven

          Nope. Rooting simply opens access previously inaccessible parts of the file system/phone…think of it as putting in your passcode… nothing actually changes, just your access.

          Now, unlocking the bootloader/custom roms, those are a different story.

          • David Moylan

            thanks for the info…it worked like a charm 🙂

  • Nish Junankar

    Does this mean google wallet should work with the RAZR HD after an unlocked bootloader/rom comes out?

    • Mordecaidrake


      • Mark Mann

        how would we go about loading up google wallet once the boot loader is unlocked and we are rooted?

    • Joe

      I didn’t think the razt hd had nfc. I could be mistake

      • evltwn

        Yes it has NFC.

    • Google blocks rooted phones from using wallet, but there are some tricks to bypass that stupidity

      • tyguy829

        no it doesn’t…it just doesn’t offer support for them. i.e. if you screw it up, not their fault

      • George L

        Google DOES NOT block rooted phones from using wallet. [ooks over at his rooted Nexus 4 and Nexus 7, both of which have Google Wallet installed and working perfectly fine]

        What you will see though, at the top when you open the app, is a message saying “Unsupported device.” Which has a link that states the following (when clicked on and taken to your browser):

        “Unsupported Device Policy

        Some users may disable important security mechanisms in order to gain system level ‘root’ access to their device. We strongly discourage doing so if you plan to use Google Wallet. We are unable to support devices with unauthorized operating systems as the security layers of the device may be limited.”

        Basically, when it comes to security with Google Wallet on a rooted device… you’re on your own. Google won’t be held responsible. Nothing more, nothing less.

        EDIT: The CARRIERS, however, DO BLOCK SOME PHONES FROM USING WALLET. Looking at you Verizon. In which case, rooting/unlocking your bootloader (and device) IS required in order to bypass that stupidity. But that’s completely different from saying Google is doing the blocking. It isn’t.

      • duke69111

        Google does not block it, it just simply puts a statement at the top of the app that the device is an Unsupported device. If your lucky you can download it from the market, otherwise just get the apk off of xda. It should work on the Razr HD.

        • kixofmyg0t

          It won’t. The install fails.

          • George L

            Look around on XDA. For some phones there are workarounds required to install Google Wallet. The various Samsung Galaxy S3s have this issue.

  • George Fayad

    ” He urges you to consider your future purchasing decisions based upon the dev-friendliness of phones rather than waiting or expecting methods like his to be released by the community.”

    +1 to this. I have a RAZR HD because it was given to me through work, but I’ve always suggested that power users should buy based off openness, and quality, rather than brand loyalty and sales.

    • True to some degree, but I take it a little different. Some devs like a challenge like this, to try and get ROMs to work under such a situation that the bootloader can’t be unlocked. The RAZR line are good phones, and we, as power users, only take up roughly 5-10% of the total market on Android. The rest of the consumers won’t bother doing research on the phones and just buy whatever the stores tell them.

      I stick to Motorola for a couple reasons. Their phones feel very good in my hands, even the Droid RAZR did. Most of the other OEM’s don’t, and since I’ve never really liked Samsung, I don’t consider them when buying a device, and still won’t. HTC just has ugly phones IMO, but hey, that’s the thing about Android devices, we have a choice in what we can buy. So, if one likes Motorola, they should buy Motorola if they want. Same with HTC and Samsung, LG, Sony, and many others.

      At least Motorola has one good thing about many of their phones. They’re about damn near impossible to brick due to the factory images they have and the restore tool.

      Mk, that’s my .02.

      • DavidB

        I doubt it is anywhere even CLOSE to 5%. Likely much less than 1% of all Android phones get rooted I bet.

        • All of mine are guesses. I never say its a true statistic or anything.

  • p3droid

    Not a bad way to go out, bootloader and root. I hope he has a good retirement.

    • ArrowCool

      He totally just pulled a Costanza


      • Sean Carey


      • George L

        I’ve done that numerous times. As a fellow George I felt I had to. (I also am a fan of randomly busting out his “worlds are colliding” speech, especially when it’s happening to me.)


    • MichaelFranz

      Seriously….this is one of those people who deserves it, but you also hope he comes out of retirement. Applause to Dan all around
