Important information:

- If you get to a point where you don’t want to go any further, or things don’t work, you can always flash the stock rom (extract the .tar.md5 from the zip) using Odin in your bootloader. Get that here:http://forum.xda-dev…d.php?t=1755386

- Do not attempt this hack if you’ve disabled apps. Re-enable them first or use the stock ruu from above before attempting this. (You’ll save yourself a bunch of time)

First off, you’ll need some files. This basically flashes a custom system.img.ext4 which has your su binary. You then boot up and flash cwm or twrp


1. USB Drivers: http://tinyw.in/Fdoz
2. Odin: http://samsung-updates.com/Odin307.zip
3. One Rooted system.img tarball:

4. One recovery image:

Ok, lets get started….

1. Boot into Odin mode on the phone. Do this by powering off and then holding vol down, home and power to power on. Then press vol up to accept the disclaimer. Plug into your computer.

2. Fire up Odin (Heimdeil may work in linux, haven’t tested) choose the PDA section and browse to wherever you downloaded rooted.system.img.tar then click flash. This takes awhile, be patient. Took me around 8 minutes to flash this.

3. It will auto reboot. It should boot up and thing should act mostly normal except that you’ll be able to adb in and use su to take root

If you don’t want a custom recovery, you may stop here. You are rooted.

Continuing on to get a custom recovery on your device…

4. You’ll need adb installed and working for this. If you don’t know how, this isn’t the thread for that. Open a command prompt and follow these commands:

<cd to the directory with the files you downloaded earlier>
(if you downloaded twrp8.img, use that instead of recovery.img in the commands)

adb push recovery.img /sdcard/
adb shell
su
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p18
reboot recovery

5. Profit

EXTRA CREDIT: Hate the VZW boot logo and audio as much as I do? Flash this in CWM:http://www.mediafire…m6urrypvx2c156p
Its a stock Samsung Boot animation (pulled from Blazer ROM)

enjoy :)

Many others for bits an pieces for this whole thing

FAQ:

Q: It’s not working!!! Keeps failing!!!
A: Try again. Turn the phone off (battery pull) and boot into download mode again

Q: Odin doesn’t seem to be doing anything!
A: Be patient, it can take awhile sometimes. I’ve also noticed if you try to flash something, and leave the phone plugged in and try to flash something else it won’t work. Unplug, then replug, then try flashing again

Q: Does this trip the flash counter?
A: No

Q: Can we flash custom kernels?
A: Not properly at this time. If we flash to our boot partition, we’ll end up with this:http://i.imgur.com/Ci0gY.png We can still recover from this by booting into odin mode and flashing the stock boot.img, found here: http://goo.im/devs/i…tock.kernel.tar

    I am a newbie at this but was curious, can you receive software updates from vzw with the GS rooted?

  • peapod

    The link for the CWM recovery doesn’t seem to be working. Where else can I get it?

  • ivan

    Will this let me use this phone on a different phone network

    • DroidModderX

      No

  • Jess

    Recovery links are not working, any other place to get?

    • jess

      after reading a bit found this for anyone else looking for link

      1. After following above process, download “Rom Manager” from the Play Store

      2. Open Rom Manager

      3. Select “Flash ClockworkMod Recovery”

      4. Select “Samsung Galaxy S3 (Verizon)” down at the bottom and let it flash

      5. Once completed you can reboot to CWM by selecting “Reboot into Recovery” from Rom Manager

      • DroidModderX

        Also you can install ez-recovery from the play store which allows you to switch between recoveries.

  • Jess

    I cant get any of the image links to work now?

    • DroidModderX

      Use ez-recovery app

  • Jschneider

    The recovery image links only leads to a list of file downloads, none of which are .img files. I get a whole bunch of .pit files

  • FrankieJ1978

    hey there..there is no rooted.system.img.tar file..i only system.img.ext4 and it’s not letting me choose that file to download when I fire up Odin..any suggestions?

    • DroidModderX

      Try the newer debugfs root method instead

      • FrankieJ1978

        can you explain a little further into detail? Where can I read about this method? Thanks!

        • DroidModderX

          I’m sorry, check the side menu under “walkthroughs” third link down

  • Matt

    the command window is telling me that “adb” is not a recognized command. What am I doing wrong

    • DroidModderX

      You need to install the sdk

    I’ve had the Odin flashing for almost 1/2 hr and still not finished. I’m getting worried. Is there any way to check to see if anything is going on?
