Thank's to all fellas at XDA who first tried out this rooting technique. This method was originally posted via XDA-Developers original thread.


  1. Is there any way to know if this will work for the S4 Active (SGH-I537)?

  2. I have a GS4 with Android 4.3 but the build is UCUEMJ9, Have you tried this build? I have seen this solution you mention but for a different build.


  3. I have been having trouble finding a guide that works. This method worked great for Samsung Galaxy S4 SGH-I337 for AT&T. I followed the instructions carefully, and I downloaded the root checker app from the play store and I now have Root access.

    1. I did the same too, but my purpose was to go back to 4.2.2 have you tried this, is it possible to jump back after this root.

  4. i have been trying for a week to root my Verizon sch-i545 s4 build #vruemk2 with no luck what so ever. this article looked promising, the command prompt runs its course but when i open super user it will not allow me to update binary. something has been put onto the phone because after a reboot the screen looks a little different, it says Samsung then custom with a padlock picture. also i get verizon notifications saying software change blah blah blah. dont remember the exact wording.
    anyways is there anybody who can walk me throough what i might be doing wrong or where i need to manually put the superuser update on the phone itself. i use wondershare mobilego for android as a manager for files.

    1. also i am not sure how to be contacted directly on here if that is an option

  5. What does it do to your phone??
