Motorola RAZR HD, RAZR M, and Atrix HD Bootloader Unlock Released (Updated)

motorola bootloader unlock

Yesterday, news broke that Dan Rosenberg (@djrbliss) had unlocked bootloaders for a handful of Motorola devices including the DROID RAZR HD, RAZR MAXX HD, RAZR M, and Atrix HD, all of which are powered by Qualcomm chipsets. Today, he has released that same unlock tool so that you can free your phone from Motorola and Verizon’s clutches.

We should point out that you cannot re-lock the phone after using this tool (at this point), and it does indeed void your warranty. Also, Motorola can more than likely patch this in a software update, so you may want to weigh your options here before long. It’s risky from a warranty and replacement standpoint to say the least. As always, proceed with caution.

You definitely need to be rooted ahead of time, prior to using this tool. For those with a RAZR HD running Android 4.1.2 (the newest update), root has not been gained yet so you are out of luck for now. I can’t imagine that this won’t ever be rooted, but again as of today, there is no root method.

Update:  Dan released a root method for Android 4.1.2 that can be found here.

As we mentioned yesterday, this method does not work on OMAP powered phones, including the original RAZR, Bionic, and DROID 4. Do not attempt to use this on any of those phones.

Below, we have the basic instructions and notes from Dan. 

A couple of warnings:

  1. You understand that using this tool will permanently, irreversibly void your device’s warranty.
  2. You understand that it may not be possible to “relock” your device’s bootloader after unlocking using this tool. A side effect of this is that if you lose your device and you are not using disk encryption, a malicious party who acquires your phone may be able to extract all personal data from the device regardless of any lock screen.
  3. You agree that I am in no way responsible for any damage to your device as a result of using this tool.


*It requires that your device has been rooted and that the “su” binary has been properly installed.

  1. Download this file to your computer.
  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 your device has been rooted and you have a working installation of “su”.
  5. Ensure USB Debugging mode is enabled on your device.
  6. 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”.

Note – If you are interested in reading exactly how Dan managed to find this exploit (all of the technical madness), he has written up an entire post about it over at Azimuth Security.

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

  • jdcraig1

    Android version 4.1.2
    Model XT912
    Build 9.8.20-72_VZW-16
    Rooted using razr blade

    I keep getting an error when I attempt to use this.

    [*]Unlocking Phone

    [-]Couldn’t find target

    The phone will reboot in bootloader mode then

    getvar:all FAILED (remote: Unsupported command)

    Am i missing something?

  • mikeym0p

    I have a Razr M rooted 4.0.2 w/ safestrap. I ran the script and it leaves my phone in AP Fastboot mode status locked, with the reason ‘reboot into bootloader’. If I continue the script it reboots the device, is anyone else hitting this roadblock?

  • BFRapv

    ok call me a DA if you want but i has atrix hd 4.1.1 have root access and safestrap on it as well but when i run the file it says

    pkg: data/local/temp/superuser.apk

    When booted into ap fastboot still shows locked, code status 0
    any respectable tips would be great if not, thanks anyway, will be donating friday.

  • Stache

    Will this wipe all data on the phone?

    • answerman


  • Mark Mann

    as it’s been awhile since i’ve had a phone with an unlockable bootloader(og droid) i have but one question, will this stop me from taking any ota’s that may get pushed after i unlock my bootloader(i.e. 4.2, klp)?

  • Now to find some kick ass roms for the Razr MAXX HD.

  • kane

    I’m going to make up a rumour here. Be sure to spread it around as fact: At Google IO all future phones will be unlocked an rooted on Key Lime Pie regardless of OEM

  • schoat333

    4.1.2 root and now unlocked bootloader. I’ll be honest, I recently got an iPhone, but this brought me back, and now my wife has an iPhone.

  • trophynuts

    how long before some DA doesn’t read all of the warnings and instructions and bricks his OG RAZR….and then blames Dan for it.

  • Before you do this on Fedora 18, you may need to do:

    sudo yum install libstdc++.i686
    sudo yum install ncurses-libs.i686
    sudo yum install zlib.i686

  • Nope

    If somehow i could’ve managed to create a list of 1000 things i wished to see on droid life today.. this would’ve been 1001. Never thought i’d see the day. MAXX HD 4.1.2… unlocked!

  • overclock

    I want to upgrade but can’t. And the Maxx HD goes for practically as much as retail on feebay. Oh well. Congrats to the dev and all those that get to unlock.

  • chucklehead322


  • Looks at wife’s HD Maxx….. Looks at my Nexus….. starts the backup procedure…….

  • Nathan Einsig

    I just unlocked my RAZR HD, which was rooted 4.1.2 OTA. Just to clarify, I had kept root with Voodoo when taking the 4.1.2 update. If you are on 4.1.2 w/o root you are SOL for now.

  • If the bootloader can’t be re-locked. I’m out. I am rooted and on 4.1.2. But I have had to send my phone to VZW WAY too many times to have a UNLOCKED bootloader show up. Signs of root is one thing. Unlocked bootloader is another.

    • kixofmyg0t

      Why did you have to send your phone back to Verizon?

      • Loads of issues due to manufacturing errors. I don’t like knowing this would screw me over as far as getting replacements if needed. If the bootloader can be RElocked. I’ll jump right on board. Right now too many ifs.

  • I have a Droid 4… why can’t we have it? ;-;

    I know why, but still, it’s depressing.

  • If rooted on 4.1.2 can the bootloader hack be used?

  • endurotech

    Looks like the update for 4.1.2 came 3 weeks ago. If I were to use an upgrade on my Verizon account for a RAZR MAXX HD would it come with 4.1.2 or not?

    • kixofmyg0t

      It shouldn’t. But the first thing it’ll want to do is update.

  • luzlingrofl

    The Moto OMAP devices use a bootloader bypass method called Kexec. It’s basically the same thing as having as having an unlocked bootloader so its not so bad for us non Snapdragon devices

    • endurotech

      Except custom radios can’t be flashed and we can’t flash SBFs to downgrade

  • positivehxcgo

    All of us OG Droid Razr users sit here in envy… Grats and thanks Dan!! Always working hard for the community

  • MichaelFranz

    Poll…Would you trade your 16GB GS3 for a Razr HD or Maxx?

    • PopeFrancis

      I’d trade one for a locked HD 😉

      • MichaelFranz

        i want a Maxx HD i have a guy willing to trade for a HD. Very tempted.

    • Detonation


      • MichaelFranz

        Reasoning? See my note above, im not thinking by OEm software standards, this is completely from a Dev Community prospective, if it picks up to the likes of the GS3, or a nexus

    • Hell no. I have the 32GB; 16GB is still a Hell no 😉

      • MichaelFranz

        Well I have 32GB SD card i would keep. my only reaosn behind it is that the moto hardware, radios, and battery are overall better. And with this being unlocked, if the dev community picks up these probably would be the better phones to have I think.

    • Fan

      I just did last week!

  • slider112

    This is a good day! Bravo!

  • So is being rooted the only requirement? Can I do it on the latest OTA update?

  • Question: Why would I actually want to root my phone? I am not trying to be a jerk, I genuinely just don’t understand the actual advantage. If the “advantage” is installing custom ROMs, that just doesn’t seem to be enough for me to both with this.

    • schoat333

      This isn’t about rooting your phone, this is about Unlocking the bootloader. This opens up a much larger world then just ROM’s. Google it for more details.

    • justincase_2008

      I root to use Titanium Backup and Root explorer and thats about it. So if android had a nice file explorer and back up system for app data i wouldnt use root at all.

  • Picture change!

  • Trueblue711

    Anyone else dying at the “result in injury to users” claim on Motorola’s warning? Hah!

    • Big_EZ

      You could make changes that could cause the battery to drain very fast to the point where it becomes unstable and explodes, so no. They have to cover their @ss, most likely nothing will happen but it’s possible.

      • Trueblue711

        Then why don’t the developer editions, or any other phone with an unlocked bootloader, come with such a ridiculous warning?

        You could also overclock any Intel processor and cause it to burn itself up, amongst other things, but there’s no such ridiculous warning. It’s a Motorola scare tactic.

        • kixofmyg0t

          They do. They also don’t come with a warranty.

  • poolgod10

    can this be done to the Droid X?

    • No.

    • T4rd

      Do you see the Droid X listed among the three phones specified?

    *Cue Ren and Stimpy episode


    • Brandon Golway

      Good ol’ Stinty Wizzleteets!

  • kixofmyg0t

    RAZR MAXX HD reporting in. Still on 4.1.1. Unlocked.

  • Alexander Garcia

    I’m sadly at 4.1.2 on my HD Maxx = SAD… FACE…

    • kixofmyg0t

      Are you rooted?

  • now for the roms

  • P3Droid

    1) Don’t bother Dan with questions, he is not a help desk.
    2) Break it you fix it.
    3) Once unlocked that is permanent, but this can be fixed by Moto in any future update.

    • schoat333

      Just to make sure I’m understanding number 3 correctly. The exploit used to obtain unlock status can be fixed by Motorola. If you unlock, is there any way for them to re-lock you with an update?

      • p3droid

        no unlocking is permanent.

        • MichaelFranz

          P3droid – is there a way to revert back to 4.1.1 if a device has been upgraded to 4.1.2? My understanding is no, but i know you are a-for-mentioned expert 🙂

          • p3droid

            not unless you are rooted.

  • Question is, will I find a rom for the device now?

    • You don’t instantly get ROMs when a device is unlocked.. give em time.

      • I mostly was more interested in knowing if we’d even see roms/teams building for the devices. They’ve been out for some time so interest may have waned.

  • George Fayad

    This is great and all….but……can i get back to 4.0.4 from 4.1.2 yet?

    • If you unlock you can.

      • George Fayad

        But you need root to unlock…and to root you have to go back to 4.0.4….did i miss something here?

        • Yeah, you weren’t supposed to take the 4.1.2 OTA as warned on DroidRzr and other forums 😉 You gotta wait for a root exploit if one ever comes for it.

          • George Fayad

            I didn’t take it on purpose. I was rooted on the 4.1.2 OTA and messing with my build.prop file. Walked away because I got called to a job, came back and loaded what i thought was the original build.prop but it was my modified one that i wasn’t finished with. Missing a boat load of lines, wrong values etc. My own fault for hacking while distracted. Ended up not being able to go back to 4.0.4 so had to SBF to the 4.1.2 image and i’ve been waiting ever since.

  • Derek Traini

    I got a RAZR HD with 4.1.2 rooted and Safestrap available, am I ok to proceed?

    • Yes you are.

      • Derek Traini

        Thank you very much.

      • Lucas Gorski

        So having root is the key here, regardless of which build you’re on. Is that right?
