HOW TO ROOT SAMSUNG GALAXY S3 SC-03E RUNNING ON ANDROID 4.1.1

  1. Download the CF-Root for SC-03E on 4.1.1 from this link.
  2. Download the Odin flash tool for your computer from this link.
  3. Drag both files from the default downloads folder over to the desktop.
  4. Right-click over each of the files and click on the “extract here” option.
  5. Double-click the Odin executable and wait for the Odin app to open on your computer.
  6. Turn off your Japanese Samsung Galaxy S3 and reboot it up in download mode.
  7. Connect the Japanese Galaxy S3 to the computer using a USB cable.
  8. Click the PDA/AP button found on the Odin user-interface.
  9. Do not change the default settings from the Odin user-interface.
    Click the Start button and the Odin app on the computer will now flash that CF-Auto-Root file for the SC-03E smartphone.
  10. Wait until you can see the pass message from the Odin user-interface and your Japanese Samsung Galaxy S3 automatically reboots.

Your Samsung Galaxy S3 from Japan now has root access to the internal system by enabling SuperSU. The SuperSU is now available from your device’s app drawer and it should remain there until you want your device unrooted. The SuperSU will grant root access to the apps you want to have rooting permission, but also block apps until you grant them permission, making it easy for you to block malware and it impossible for malware to get access without your permission.

The CF-Auto-Root package does not install a custom recovery on your Galaxy S3 smartphone like some other rooting tools do. You can, however, install a custom recovery on your S3 handset now that you have root access. You can follow any guide that is available for that.

Now you can learn everything you need to know about unrooting the Samsung Galaxy S3 DoCoMo SC-03E smartphone for when you want to return the device back to stock firmware.
