  1. i was wondering if there is an unroot for the galaxy s3 for sprint because i rooted my phone but its asking me for an update fix but since i have the phone rooted i keep dismissing the msg…please help

  2. Everything works great for me until step 18. After Odin when I reboot via volume up, home, and power at the same time I boot into Android System Recovery and not Clock Work. Can anyone help with what I might be doing wrong?

    1. Mahesh Makvana

      Either the ClockworkMod Recovery isn’t successfully installed on your phone or you didn’t press the key combination correctly.
      Turn OFF your phone, remove the battery, re-insert it and then boot into the recovery mode.

  3. I got a message when flashing the super user zip. It said e: signature verification failed. Can someone please help

    1. Mahesh Makvana

      In the Step-19, after choosing “install zip from sdcard”, choose “toggle signature verification” to OFF.

      It will solve the problem.

  4. I got to step 16, but my phone never resets. Odin says it completed and succeeded, but my phone doesn’t do anything. I saw on youtube there’s supposed to be a blue bar going across my phone’s screen, but that doesn’t happen either. Any ideas? Thanks

    1. Mahesh Makvana

      Did you checkmark the option labeled “Auto Reboot” in Odin? If you didn’t, then restart your phone manually. It should solve your problem.

      Thanks !

      1. I have tried it with auto reboot checked and unchecked. it does restart when its checked, but afterwords I still can’t my phone to launch Clockwork, so I don’t think it worked. I’ve tried multiple Clockwork files, in case I had the wrong one, and none have worked. It always goes to android system recovery

        1. Mahesh Makvana

          Well, some of the users have gotten success to enter into CWM Recovery while others haven’t. Discussion about this issue is going on on several forums, we’ll let you know if we find something that can fix your particular problem.

          Thank you !

  5. Is it possible to do the firmware update on a rooted phone? I did the above method to root, with no problems, but now I’m getting constant firmware update notices, the one time I tried it, it kind of looked like the CWM killed the update.

    1. As far as I know, you can update your firmware even if you are rooted. But, when you do so, the root access will be lost and you’ll have to re-root your smartphone.

  6. I updated my firmare I have the uvlh2 on my galaxys 3 T-999 T-Mobile and this root method doesn’t work anymore do you guys have the new root file 2 flash in odin?

  7. Can’t navigate on this screen. Couldn’t even when count was 1, so I repeated the flash and got 2 counts. Where do I go from here? I can still boot normally if I want. Thanks. S3, T-mobile

    CUSTOM BINARY DOWNLOAD: Yes (2 counts)

    1. At the moment, we have the procedure for Windows PCs only. We’ll let you know when we’ve something for your Linux PC.

      Thanks Ken!

  8. I have verizon now and use a tether to make hotspots with my rooted phone but am thinking of switching to sprint but have heard that they do something to block you from tethering, does anyone know if ic an still use a tether to make hot spots and use the internet under my unlimited data instead of paying for their separate hotspots?

    1. I have sprint and my galaxy is rooted. Wifi tether works perfect. No issues but one that i can only run 1 device. Been tethering for years on sprint. And when you root make sure the baseband version is the same as yours. Ie. T999UVDLJC. that has to match with the one your installing or it won’t work.this is the newest build on ics

  9. Help needed: I rooted my SGS3 according to the above, simply because I want PPP-EO installed. (in my house I have point to point broadband)
    Installation worked fine, but the ppp widget still does not work. It seems the kernel does not support async ppp. The effect is that PPPOE logs in but directly goes offline
    Now how to solve? Anyone knows?
    (btw, Im not an expert, so I really need help/ detailed help……)

  10. says signature verification failed when i clicked the file form my sd card… did not give me the same options as said in the description….it used the word “external storage” and not sd card…and when i selected the file it gsve me the error,…..tried a dozen times, any ideas on what i can do now?

    1. After you select “install zip from sdcard”, you’ll see an option called “toggle signature verification”. Just turn it OFF and you should be fine.


  11. Followed the instructions and everything went smooth…so I downloaded root checker just to verify and it says “Sorry! This device does not have proper root access” even though I have the su icon now…any thoughts

  12. when i do the busy box i get a message that says something about the shell not being there or something and when i click on the red X, the app closes all the way out. downloaded root checker and it said my phone isnt rooted and i did this same method. thank you if you can get back to me asap.

  13. I’m using the cable camed with phone but when open odin it doesn’t seem to recognize it nd the square isn’t yellow help? I tryed re installing the files samme thing using windows 8.1
