Hello , Do you know what i would have to do to make this work on t mobiles gs3?

You would need a different TAR file than the one I provided to flash a device appropriate version of CWM. In theory, as soon as you have that this method should work pretty much the same.

Mind you, there may be another method of attaining root on the T-Mobile version, but I'm not an expert. Think of me as more of a Dev to Beginner translation service :p

EDIT: You don't actually need a different TAR file. This method is confirmed to work for the T-Mobile version without any modifications. It should in theory also work for the AT&T and Verizon versions, though that's unconfirmed at this point.

The same method would work, but like as you stated, a different tar file, specific to that device would be needed, then follow the simple procedure.

I'm fairly new to the Galaxy S3. Is the NAND unlocked by default? I wanted to modify the hosts file but I'm getting permission denied via ADB when I try to push them back.

EDIT: So after some studying I figured out that the default.prop setting is "ro.secure=0" (I wasn't aware this was ROM dependent since I've been on CM my whole life). I need to change to 1 to allow for adb remount to mount the system partition as writable.

@everyone else: If anyone has flashed cwm and done a backup can you send me or post the boot.img please.

Thanks.

I added insecure adbd to the boot image you sent and packed it into a tarball to see if it would unbrick some peoples phones who flashed the gsm boot image. Someone posted that it put the phone in a boot loop but I had a T-Mobile user message me saying it worked on his phone.

Just waiting for feedback.

Mark.

    First off, let me say that I did not develop this schtuff and all thanks should go to those that did. Special thanks to noobnl (his thread here), mskip and TeamEpic for all their work.

    A note about these instructions:
    They're long and may seem a little daunting to those that aren't experienced. Please don't let that deter you as they've been written to be as simple and easy to follow as is reasonably possible assuming you can work a Windows PC and extract a zip file.
    ==> If you encounter problems with these instructions, please check the FAQ in the post following this one. <==

    For video instructions (courtesy of qbking77) scroll to the bottom of this post.

    General Disclaimer:
    Use these tools and this guide at your own risk. Doing these things wrong/improperly/etc. has the ability to completely ruin your device and YOU assume all risk and responsibility if that happens.

    Also note that rooting WILL violate the manufacturers warranty on the device making it ineligible for warranty repair. If you have insurance on the device however, they MAY still replace it for the cost of your deductible.

    Non-ADB Root instructions (Windows Only):
    First, the non-dangerous, standard user stuff:

    1. Download and install the Samsung USB drivers from Samsung's website: http://downloadcenter.samsung.com/c...nt_L710_GSIII_Samsung_USB_Driver_v1_4_6_0.exe
    2. Turn on Debugging on your Phone
      • Open Settings
      • Select "Developer options" in the System section
      • Check the box for "USB Debugging"
      • Press "OK" to confirm.
    3. Plug you phone up to your computer using the USB cable and allow the drivers to install.
    4. Download CMW_SuperUser_v3.07.zip from the bottom of this post
      • I recommend making yourself a nice little GS3 folder in your downloads folder for all this stuff so it's easy to find
      • DO NOT UNZIP!!
    5. Copy CMW_SuperUser_v3.07.zip on to the Root of your GS3s INTERNAL storage (if you put it into a folder, you may have a hard time finding it later, but that's on you).
      • DO NOT UNZIP!!
    6. Unplug your phone
    7. Power off your phone

    Now, this is the part that can BRICK your phone so follow ALL instructions CAREFULLY!!

    1. Download Odin3-v3.04 from the bottom of this post
    2. Extract Odin3-v3.04 into it's own folder somewhere where you can easily find it.
    3. Download clockworkmod.tar from the bottom of this post to somewhere you can easily find it.
    4. Reboot your phone into download mode
      • Hold down Volume Down, Home and then the Power button until the Warning!! message is displayed
      • Press Volume Up to continue.
    5. Your phone should now be in download mode, displaying a green Android and say Downloading. If it is not, power off your phone by holding down the power button and then try to get into Download mode again. Do NOT progress until you have done so.
    6. Go into the folder you extracted Odin3 into and run Odin3 v3.04.exe (you may have to Right-Clik => Run as Administrator)
    7. Connect your phone to your computer via USB. Drivers may install again; if this happens, allow them to finish before progressing.
    8. In Odin, the COM box all the way to the left should turn blue and it should say Added!! in the Message area.
    9. Click on PDA and in the Open window that pops up navigate to and open the clockworkmod.TAR file you downloaded earlier
    10. Verify that Auto Reboot and F. Reset Time are checked
    11. Click Start. Once the process is completed you device should automatically reboot and there will be a green PASS! box in the upper left of the window. You can then close Odin.
    12. Power off your device and boot into Recovery mode
      • To boot into Recovery mode: Hold down Volume Up, Home and then the Power button until the device begins to power on then release all 3.
      • You'll know you're in recover mode when it says "CWM-based Recovery" at the top of the screen
    13. Install CMW_SuperUser_v3.07.zip that you copied onto your internal memory
      • Navigating ClockWorkMod Recovery: Use the Volume Up and Down rocker to change the highlighted option and the Home button to select an option. The Back softkey works, but will not be lit and will take you back one screen.
      Installing a zip:
      • Select "Install zip from sdcard" (Yes, I know it's on the internal storage.)
      • Select "Choose zip from sdcard"
      • Select the zip you want to install; in this case CWM_SuperUser_v3.0.7.zip
      • Select "Yes" to begin installing
    14. Once the process has completed use the Back arrow to get back to the main recovery screen (Remember: it works, but it's not lit) and select "reboot system now." Once your device boots up you should now be 'Rooted,' but there's still a few more things to be done
    15. Install BusyBox. There are actually several ways to do this, but the BusyBox app in the Google Play Market is quick and easy.
      • Install BusyBox (this is a link to the online verison of the Google Play store. You can actually follow this link and install it from there and it will get pushed to your phone. Alternatively, just search for BusyBox in the Google Play store and it should be the first app in the search results from author Stephen (Stericson))
      • Open BusyBox Free from your App Drawer
      • Allow it Root access when it prompts you
      • Tap the red "X" to close the dialog window that pops up
      • Allow BusyBox to scan you phone
      • Tap "Install" to install BusyBox and make the necessary file changes.
    16. Update your Binaries.
      • Open the Superuser App from the App Drawer
      • Get into settings (the wrench icon in the upper right of the screen)
      • Select Su binary under the General section towards the bottom of the list
      • Select Update
    17. Your device is now rooted and all set.

    Thanks again to qbking77 for the instructions video!

    P.S. If you are a developer or I have used some of your material and/or you feel you should be credited, please let me know and I will update this post.

    Frequently Asked Questions

    This FAQ is in the works as more questions roll in so I'll do my best to keep it updated.

    Q: Odin failed! What do I do!?
    A: Try plugging your USB cable into a different USB port on your computer and/or try a different USB cable (Odin's picky about the cable). The drivers may install again; if so, wait for them to finish. After that, verify that the device shows as Added in Odin again and click start again. If that still fails, try unchecking F. Reset Time box and removing any MicroSD card you have in the device, plug the device into (yet another) USB port and try again.

    Q: Will these instructions work for other US (LTE) versions of the GS3?
    A: I have not personally tested this method on any other versions of the GS3 but uoY_redruM and carrrnuttt (and others) have confirmed that this method works for the T-Mobile version as well. It should in theory also work for the AT&T and Verizon versions, though that's unconfirmed at this point.

    Q: Ok, so I've got Root. What now?
    A: That's entirely up to you. Root allows a near endless amount of customizatoin, but some of the most commonly sought after benefits of Root are these:
    • Root Only applications. These allow you to simply do more with your phone or tweak the way it functions. Some that I personally recommend are:
      • Titanium Backup and its Pro Key => For making backups of your apps, app data and system data and uninstalling or freezing Bloatware.
      • Quick Boot => For booting drectily to recovery or Download Mode (listed as Bootloader in the App)
    • Removing Bloatware => I recommend Titanium Backup for this
    • Loading custom ROMs. There aren't many floating around just yet, but I expect that'll change soon as the ball gets rolling.
