CyanogenMod Posts Update to Galaxy SIII Build Using New Unlocked Bootloader

The kexec development to get custom kernels onto the locked-down Galaxy SIII was nothing short of valiant, but since yesterday things have changed. An insecure bootloader can be flashed to the device now making things much easier. To reflect this change, the CyanogenMod team has released an alpha build of CM10 that has to be paired with the new bootloader.

This build has better 4G connection than had been reported in the earlier builds along with a few other bugfixes and changes. The link below has the downloads for both the CM10 file and the bootloader in case you missed it.

    Working very well. Long sms messages get split into two and netflix will not work at all. I could not find a way to get camera to save to sd card. Data and all critical things seem to be working perfectly.

  • Worth noting: Requires a GApps flash as well.

  • AAAAAAAND bootloop’d. Great.

    I’m running Synergy’s latest nightly. Does anyone know if I can use this to unlock and keep running Synergy, and if I have a problem can I restore a nandroid? Can this be relocked if necessary?

    Easy Peasy 1 step Unlock. Get it before it gets pulled from the Market: https://play.google.com/store/apps/details?id=com.mmmeff.ez.unlock

    • Mario Mendez

      Can you please upload the app

      • Esteban_Colberto

        Click on the link in my post. It takes you to the android market where you can download and install it yourself. It’s free and hasn’t been pulled as of this time.

        • Mario Mendez

          It wont let me download the app from the Google Play Store directly from my Droid X. I plan to get the Galaxy S3 and want to keep the G S3 Bootloader unlocker app in a safe place till I get the Galaxy S3. I downloaded the app from the official Rootzwiki topic and uploaded it on my Box.com account.

          • Esteban_Colberto

            Careful. If any OTA is released by Verizon, this tool will be useless until they come up with a new unlock method. If you wait too long to get an S3, it may already come “patched” and unable to root or unlock the bootloader. They managed to lock the original HTC Incredible after the gb update. It took forever for them to figure that one out, and it wasn’t pretty. This app could brick your phone otherwise.

            Has verizon ever patched an exploit to a bootloader ever? I’ve never heard of them doing so

          • Esteban_Colberto

            We’re just splitting hairs now. My point is, the root and unlock methods have to keep up with the OTA updates. The app will probably be updated as OTA’s are released, but sometimes, their tricks get patched. If they don’t, there could be issues. I mentioned the Incredible as an example of a phone that was rooted until the GB update. Then, you had to downgrade hboot just to get root again. HTC unlocked the bootloader and it was still a pain to get root (obviously not for devs). Here is a quote from the developer that posted the unlock method ”
            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.”

  • Running this now. Absolutely wonderful. Can confirm that phone number and MMS functionality remain after a reboot. I’ve never had problems with 3G as I am in a very good 4G area, so i can’t really test that.

      How’s the camera with pictures and recording video?

    • Alec Bush

      Are there any downsides to this, being an “Alpha” build?

    • Droosh

      I tested his 1st alpha. Can you comment:
      1. Does the dock audio work?
      2. Does netflix work? Does it work with Imoseyon’s LeanKernal V0.4 for AOSP non-kexec? (I heard this might fix it.)
      3. Is haptic feedback still wonky?
      4. Does GPS lock as fast as TouchWiz roms?
      5. Does it still run a bit hot?
      6. Camera and Video Camera?
      7. Any other bugs versus TouchWiz ROMs like Synergy?

    As a Razr owner, am completely jealous…..takes all of a few weeks to get the locked BL dealt with on the SIII. Have had my Razr for months. Guess I picked the wrong phone…..

    • mustbepbs

      To be fair, Moto has been at the locking game longer than Samsung 😉

      • Aardvark99

        So Samsung’s software development incompetence is, in this case, a plus?!

        • Actually I believe it is more of Samsung sucks at keeping internal software internal. Someone leaked an unsecured bootloader for the phone that is likely used for internal development purposes.

          • DroidBricker

            I don’t think Samsung leaked this by mistake. F-VZW!

          • Derek

            It certainly wouldn’t have been planned. This makes the developer version of the phone entirely pointless.

    • OMJ

      to be fair you knew the razr was going to be locked when you bought it

    • BlueLetter

      You say that like you had a choice between the RAZR and the Galaxy S3 months ago.

    • zepfloyd

      Keep in mind they are locked down VERY differently. There are many more encrypted partitions on Moto devices. the GSIII got lucky in that a leak occurred of an unsecure version of the bootloader. But even without it, only certain sectors of the partition were actually locked down, meaning at some point, with reverse engineering, it (probably) would have been compromised at some point, can’t say the same for Moto.

    • Droosh

      We were just lucky that a certain “African-Canadian Sock Monkey” leaked it. The encryption wasn’t broken or anything.

    • J Dub

      There’s a difference in a signed bootloader and an encrypted bootloader. Pretty sure Moto is rocking a signed and encrypted bootloader. From the sounds of things what us SG3 owners are rocking are more along the lines of a leaked unlocked aboot.img which is a different beast.
