For those of you who want to root your Samsung Galaxy S4 Android smartphone, here’s how to do it easily using MotoChopper, a root script used on Motorola Qualcomm devices.
This root method will work on all Qualcomm-based Galaxy S4 running Android 4.2.2 such as T-Mobile SGH-M919, Sprint SPH-L720, US Cellular SCH-R970, Canadian SGH-i337M, Rogers, Bell, Telus, and other Qualcomm S4s.
For GT-i9505, T-Mobile Galaxy S4 SGH-M919, Sprint Galaxy S4 SPH-L720, Canadian Galaxy S4 (Bell, Rogers, Telus), US Cellular Galaxy S4 SCH-R970 root method, see the TWRP Root Method instead. (For Android 4.2.2, 4.3, and 4.4.2)
For Octa-core GT-i9500 root method, see the CWM Root Method instead. (Also Sprint SPH-L720 supported using CWM root method, use CWM method if you are going to install custom ROMs)
For AT&T SGH-i337, Verizon Galaxy S4 SCH-i545, Galaxy S4 Active on Android 4.4.2, see How to Root AT&T/Verizon Galaxy S4 on Android 4.4.2 instead!
Firmware Updates – Due to firmware updates being pushed out, this root method may not work on latest AT&T Galaxy S4 MF3 firmware or Verizon Galaxy S4 ME7 firmware, instead please see How to Root for Verizon Galaxy S4 on Build VRUAME7 or AT&T Galaxy S4 on MF3! [OLD] For Verizon S4 SCH-i545, you will need to flash a pre-release kernel before following this tutorial and also re-flash stock kernel, see here for details FIRST! UPDATE: For those of you with T-Mobile’s latest UVUAMDL firmware or Sprint’s latest VPUAMDL firmware, this root method will not work. BUT, you can use CWM or TWRP method below along with kernel fix to root. (See Sprint Kernel fix and T-Mobile Kernel fix)
You can use this root method on Windows, Mac, and Linux/Ubuntu.
This root method also just “gives you root”, does not install custom recovery so it is very easy to also unroot by using universal Android unroot method.
For rooting Galaxy S4 on Mac OSX, see full video tutorial here:
For rooting Galaxy S4 on Linux/Ubuntu, see full video tutorial here:
Step 1. Go to Settings->More->About device then hit “Build Number” about 5-10 times until you see “Developer mode has been enabled” message.
Step 2. Next hit the Back button and you should see a new menu called “Developer options”, hit that new menu button!
Step 3. Make sure Developer options is checked ON and also check “USB debugging” ON.
Step 4. Connect a micro-USB cable from your Galaxy S4 to your computer, you should see “Allow USB debugging” window pop-up on your phone, hit “OK”. If you don’t see it yet, just skip this step and check back on Step 7.
Step 5. If using Mac or Linux, skip this step as you don’t need to install drivers. For Windows users, go to Device Manager on your computer and make sure you have something like “Samsung Android ADB Interface” or some type of “ADB Interface”. If you don’t see it, you don’t have Galaxy S4 USB drivers installed, download and install Galaxy S4 Windows drivers.
Step 6. Download Motochopper.zip and unzip, you should find a bunch of files in it.
For Windows, double-click on “run.bat” to start the rooting script.
For Mac or Linux, type:
chmod 755 *
sudo sh run.sh
Step 7. Hit enter to begin rooting.
If you skipped Step 4, you should now see “Allow USB debugging” window pop-up on your phone, hit “OK”.
Also make sure to hit “Agree” on your phone if you see “Verify apps?” window pop up during rooting.
Step 8. When done, hit Enter and your Galaxy S4 will be rooted and will reboot.
Step 9. After rebooting, you will find a new app called “Superuser” in your app drawer, congrats!
Step 10. You can verify you have full root on your Galaxy S4 by downloading and running rooted app like Titanium Backup app.
