Unsecure Bootloader Can Now be Flashed to Verizon’s Galaxy S3

And the news of the day goes to…XDA developers who managed to flash an unsecure bootloader to the Verizon Galaxy S3. Developer AdamOutler posted up a file for Mac and Linux that will root your GS3 and apply the unsecure bootloader, leaving your device open for you to do as you please. I cannot even express in words how big of an achievement this is for the community of Galaxy S3 owners that were beyond upset with Verizon’s choice to lock the bootloader of this device

*Warning (straight from Adam) – “Let me make this clear. If Samsung updates your device’s bootloaders, using this tool could potentially brick your device. Once you apply this, never accept a factory update without first flashing the Odin Packages in the Original Post of this thread. As a general rule, you want to be the last guy to apply any Samsung update. Run custom.”

Let me say what he said one more time, so that we are clear. After applying this unsecure bootloader, you will not want to accept an update from Samsung or Verizon again or you could brick your device. You’ll have to stay with custom ROMs for the foreseeable future, to be safe.

With that said, are you ready for freedom?

Instructions:

*Mac or Linux only.

1.  Download the file at the source link below and open it.
2.  Connect your device, select “Root with DebugFSRoot” and then “Do It.”
3.  Select “Flash Unsecure Aboot” and then “Do It.”
4.  Use Odin or CWM to flash kernels to your device.

*Windows users, you’ll have to be patient and wait for someone to create a similar tool.

Cheers Mike and Jason!

    Sorry for a rookie question but.. Does this mean I can get a working JB rom now?? What does this mean exactly? I am rooted, I thought that was good and people were already putting ROM on the gs3, what what can I do now? Thanks in advance.

    • http://twitter.com/martyjones100 Martyjones100

      My JB rom works just fine. You need to go to rootzwiki and start reading..

  • machete

    if i use this and Sammy pushes an update can i just accept their update and keep root?

    • PC_Tool

      FTA:

      “never accept a factory update”

      ” After applying this unsecure bootloader, you will not want to accept an
      update from Samsung or Verizon again or you could brick your device.”

      Don’t. Just don’t accept *any* pushed update from the time you flash the unsecured bootloader on.

      Period.

      Don’t do it.

      Sorry about the extra emphasis, but this cannot be restated enough.

    Just flashed this and even with K-Exec recovery, it boots up crazy quick, and that hideous Custom Padlock is gone.

  • jimmm22

    idk why this isnt working for me but when I open up the .jar file, for some weird reason, I don’t get the option that says “flash unsecure aboot.” I get the “root with debugfsroot” option but I’m already rooted. I dont know if I’m screwing this up somehow or what. someone please help me out!

    • Sutt

      Im on Mountain Lion and I cant ever get the device to show connected

    What about the Razr :( where is kexec bootloader

  • Davros

    Any problems running this over a previous root method?

  • cgalyon

    Fantastic! Though I actually already sold mine off in anticipation for the “Developer Edition”. :-/ Still, that’s a great bit of work. The dev community is always impressive.

    Anyone think developers will be able to unlock global roaming? That is an update I want from Verizon/Samsung.

  • xformulax

    Kellex, put a link to aboot.img for the windows users… if you’re rooted you just have to dd from /sdcard/aboot.img to /dev/block/mmcblk0p5

  • http://twitter.com/jheyneman James Heyneman

    I attempted to post a link to this article on Verizon’s facebook page and it was gone in 5 seconds, LOL.

      Doing this.Brb will report haha

      • michael arazan

        In vzw website community forums at their main site, it is against the rules to even say hacking, rooting, unlock bootloader, rom, or anything else about manipulating a verizon phone, and you can not post anything from rootwiki, xda, etc, even if it is just their forums about speculations, or they will delete what you have posted!
        VZW community forums pay people to also go and post against others who are having problems with their phone, are unsatisfied with the time delays of updates, and general concerns of anything. The VZW Community Forums are censored as bad as nazi germany over there, so I presumed they’d do the same with their facebook page.

    Is it true the program works just as well on Windows?

    • Tcali

      I wouldn’t count on it as the person who made this, AdamOutler, does not offer any support for Windows users.

  • http://TransientTangent.com/ Blake Mitchell

    I did it but it feels too simple. Anyone have a test that I can use to make sure it worked?

    • Doan

      If you can flash a custom kernel, it worked.

  • Nicholas Conner

    For the record, unsecure is not a word. You’re looking for insecure.

    • Tcali

      Bootloader is not a word according to Google Chrome’s built-in dictionary & yet here we are…

      • Nicholas Conner

        Bootloader falls under ‘jargon’, or terminology which is specific to a profession, group of people, or activity. The members of the group all understand and agree upon the meaning of the terminology.

    • Bsody

      What does an unlocked bootloader have to be insecure about?

    • Doan

      English is a versatile language. Prefixes and suffixes are interchangeable on many words. There is neither an internationally, nor nationally, accepted list of English words. If a word is used enough, then it is a word.

      • Nicholas Conner

        I agree with you there, but it is commonly agreed that proper negated form of secure is insecure, not unsecure. If you perform a series of searches comparing phrases like “insecure bootloader” / “unsecure bootloader”, “insecure system” / “unsecure system”, you will typically find that the ‘insecure’ version has at least twice as many hits. I will admit that people seem hesitant to use insecure in conjunction with inanimate objects (such as ‘device’ or phone’), but by and large insecure is the preferred version.

        • TheDrunkenClam

          I can see why this conversation is down at the bottom.

  • http://twitter.com/Payaso_113 Payaso

    Yeah im lost, someone do this for me.

  • Nathan Corachea

    does this mean, whenever you reboot, it wont have to double reboot like it does if you have a custom rom?

  • J Dub

    I am hurrying up and downloading these files before a big take down letter gets sent out. Sending to all of my file backup sites.

    • Kellic

      Won’t matter. Trying to take down a torrent is like trying to take piss out of the ocean. It ain’t going to happen.

  • zepfloyd

    For those sitting on the fence, I would buy the phone now before Verizon dicks everyone over with a new and improved bootloader on new devices.

    Yet ANOTHER epic moment in Android development today. #cantstopwontstop

  • http://www.facebook.com/people/Bobby-Mei/789119685 Bobby Mei

    Any chance of this working on PC? And is it reversible?

    • chris125

      I’m curious to this as well

    • moelsen8

      doesn’t this imply that:
      “Once you apply this, never accept a factory update without first flashing the Odin Packages in the Original Post of this thread”

      • nayton7

        dont accept an OTA until you have flashed the odin packages in the original post.

        • moelsen8

          right, so it’s reversible is what i’m saying

    • J Dub

      That’s where the whole ODIN package thing comes in. Meaning reversible with an ODIN back to stock. From now on there’s no reason to need a factory update. Devs will be keeping us funky fresh way before Verizon.

    • Tcali

      Yeah; I just REposted a solution further along in the comments section.

    • http://www.facebook.com/jimmy.leang Jimmy Leang

      You can always sideload Linux.. Just saying. :D

      • Doan

        or just emulate, and save time and effort.

    • https://plus.google.com/110773438514346746273/ tjhrulz

      Just go grab ubuntu 12.10 burn it to a cd or flash drive and boot into it but dont install it. Grab the files and the follow the steps above.

  • Michael_NM

    Hey VZW! Kiss our XDAsses!

  • Tcali

    I am leaving my phone in airplane mode until a new kernel comes out, just in case Verizon catches wind of this & forces Samsung to release a patch.

    • Bionic

      Dafuq?

      • Tcali

        While the bootloader is now unlocked; There are not any ROMs with kernels that can take advantage of this feature. Plus, AdamOutler mentions the following:
        “Let me make this clear. If Samsung updates your device’s bootloaders, using this tool could potentially brick your device. Once you apply this, never accept a factory update without first flashing the Odin Packages in the Original Post of this thread. As a general rule, you want to be the last guy to apply any Samsung update. Run custom. “

        • http://www.facebook.com/profile.php?id=548497404 Hans Dirk Kwazneski

          If you do this, you’d have to be an absolute moron to accept any OFFICIAL updates from Verizon…

          • Tcali

            I thought Verizon can release silent OTAs now?

          • http://www.facebook.com/profile.php?id=548497404 Hans Dirk Kwazneski

            Nope, you have to accept… that would be pretty bad of them to do haha

    • J Dub

      Eh…just flash one of the built-from-factory-image ROM’s out there. Most of them have already removed the OTA update function.

    • Droosh

      Chill dude. If Verizon were to do that anytime soon, you could always just Odin back to the old stock.

      • Tcali

        Not according to AdamOutler; It CAN turn my phone into a nice little paperweight. I do not know about you, but I will not chance it. I mean, after all, we are dealing with Verizon here!

        • Droosh

          Hmmm. Not how I read his posts. I’m sure you are fine unless you install the unsecured bootloader without installing a custom ROM – but why would you do this?

          Accepting a Verizon update without having flashed the unsecured bootloader is fine and won’t brick your phone obviously. If you accept or are pushed an update from Verizon and at some point in the future want to flash THIS version of aboot.img, then simply use oden to revert back to the current version of stock to remove whatever Verizon had changed.

          No worries.

    • Tcali

      Wait…
      Why did I get downvoted?!?
      This makes me sad…

  • sporty

    RAZR PLEASE!!! This will show those suckers we don’t appreciate locked devices!

    • Tcali

      It is not that easy. Motorola locks their bootloader up tight, albeit I am unfamiliar with the Droid Razr’s/Maxx’s current bootloader situation…

      • Big_EZ

        The Kexec work around is almost ready, it won’t be unlocked but we’ll be able to flash kernels.

        • Tcali

          Cool!

  • Scott Willenborg

    DAMMIT!!! I was just about to unlock my S3 bootloader myself.*

    • nightscout13

      Shoot, will he be getting that crazy bounty??

      • Tcali

        Maybe most of it, but not all! There was a lot of people involved in this, from getting service manuals to getting the secureboot 3.0 specification overview. It was truly a team effort!

        • Droosh

          I don’t think it was a team effort. I think despite all the good work by the team, we have the unsecured bootloader thanks to the leak by the anonymous “African-Canadian Sock Monkey.” (And Adam who posted it on his behalf.)

          Maybe the bounty got big enough that someone at Samsung or Verizon decided to risk their job and steal the unsecured bootloader and post it through Adam?

    so what are the best roms for the vzw sgs3?

    • Nick

      SynergyRom is great, which is what I’m currently running. Great battery life, custom toggles, 4-in-one reboot menu etc. Check out the thread over at XDA.

      • Droosh

        Running this too. CM10 (for the GS3 NOT the G-Nex) still has lots of bugs in my experience. I haven’t tried Imoseyon’s LeanKernal for the GS3 AOSP, but I hear that it fixes many of them, so you may want to give it a shot.

      Making android better since the Nexus One (and before). I love our Android devs and every month brings more and more to the scene.

  • FortitudineVincimus

    There was never any doubt this was going to happen. And happen on XDA.

    At least, not to me.

    However, I don’t plan to use it. I will stick with just good old root.

    • http://twitter.com/jdhas jdhas

      Oh, there was doubt. But there was also hope.

      What an amazing thing for the Android community in general, and the d2vzw community in particular.

          • Tcali

            That was with military grade encryption; this was locked well, but had been signed.

        • Droosh

          Why not. Nobody has ever broken the encryption. We are lucky that someone leaked this.

          • Tcali

            Secboot 3.0 is new; Nobody has broken it because it had not come to market yet :)
            BTW… I wouldn’t use encryption…

          • Droosh

            I think you should double check. I thought the the signiture was encrypted with 256 AES.

      • Chronon7364

        Noob question: is it possible for Verizon (or Samsung) to put out an OTA update that would block or stop this from being possible? Or in other words, should this flash/root method be done ASAP before the backdoor closes?

        • Kellic

          Yes. Wouldn’t recommend any updates from Verizon until its been verified not to dick with the boot loader.

        • J Dub

          I say yes and no. The ODIN files are out there to take you back to pre-OTA if they release an OTA. IMHO they are pretty much SOL. You can just ODIN back to the release firmware then apply the aboot.img and you are unsecured.
