How to Root the Samsung Galaxy S4 (Motochopper Method)(Video)(Updated 09.03.13)

UPDATE 9/3/13: AT&T’s LATEST UPDATE NOW BLOCKS THIS METHOD. UNFORTUNATELY THERE IS NO REPLACEMENT PROCEDURE AT THIS TIME. WHEN ONE SURFACES, WE’LL POST IT ON THE SITE.

Maybe you’re unhappy with the amount of bloatware Samsung put on the new Samsung Galaxy S4? Maybe you want to get rid of TouchWiz? Maybe you want to overclock the device? Or undervolt it? Or change what apps can be opened using the multi-window feature on the device? There are any number of benefits to rooting a device and here at TheUnlockr, we’re pretty much convinced it’s the way to go. Here’s how to root the Samsung Galaxy S4 using a program called Motochopper.

I. Install the Drivers

1. Download the USB drivers and install them on your computer.

4. Scroll down to the bottom and tap Build Number repeatedly until it says you are a developer.

5. Hit back.

6. Click Developer Options.

7. Turn ON USB Debugging.

8.Plug in the device via USB to your computer.

II. Root the Samsung Galaxy S4

1. Download the Motochopper program.

2. Extract the .zip file to your desktop on your computer.

3. Open the newly extracted folder.

4. Double click the run.bat file if using Windows | or open Terminal on Mac and type the following with hitting enter at the end of each line:

cd desktop
cd motochopper
./run.sh

5. Approve the connection on your device.

6. Wait for it to root the device.

7. Once done, you should see SuperSU in your app drawer on the device indicating it worked.

    hey,
    i have just ‘tried’ to root my samsung galaxy s4 GT-I19505 and i successfully did the computer side of thing like downloading and putting the Superuser app onto my android device but it says that it is out of date, so i touch the install button button and intently it comes up with an error message reading “there was an error installing Superuser. Please send log of error to developer.’ but when i go look the error log it is nowhere to be found.

    what do i do?

      Turns out Motochopper is now broken via the latest OTA update for AT&T… Is this an AT&T device you are using?

      • Argooony713

      • http://bane-tech.com/ Josh Bane

        At the time it was the update prior to this update. It’s the Verizon GS4. I’m rooted now. But had to bust out the old dusty Dell to get it done.

        • http://TheUnlockr.com David Cogen

          Ah so the computer was the issue?

          • http://bane-tech.com/ Josh Bane

            At the time of my post here I was under the impression the method would work with a Mac

  • Roodly Philogene

    It does not work on Mac.

    • http://TheUnlockr.com David Cogen

      I did it on mac and it worked just fine. Why don’t you post what errors you ran into and maybe someone can help?

  • MCFLY

    There are steps missing… In this and will leave you hanging…

    • http://TheUnlockr.com David Cogen

      They aren’t missing, worked fine before, the latest update to AT&T version of the device broke this method. Are you using AT&T?

    02:56 You can’t remove TouchWiz as it’s baked into the ROM.

    • http://TheUnlockr.com David Cogen

      I meant by flashing a different ROM.

  • Dani Long

    1. A video demonstrating this root done via a Mac would be super.
    2. I know I’ll sound like a newb, but still: does this root replace the Touchwiz interface? For the most part, I like I Touchwiz. I just want to add more apps to the multiwindow function.

  • ish

    I HAVE RUN THE RUN.bat ant it keeps tellin me error protocol fault..waiting for device..
    i want to know if that is how it runs or there is a problem somewhere.

    after i followed this steps, i open the superuser, and it says “The Superuser binary (su) must be updated.Please choose an installation method. Recovery mode installation is recommended for HTC devices.” and the choices are Cancel, Recovery Install, Install. After i pick Recovery Install or Install it says again ” There was an error installing Superuser. Please send a log of the error to the developer. If i pick cancel, nothing happen. What should i do, suggest please, thanks. :)
