Samsung Galaxy S3 (Sprint) SPH-L710

Root Samsung Galaxy S3 SPH-L710 on stock Android 4.1.2 Jelly Bean firmware

The official Android 4.1.2 Jelly Bean firmware is now available for the SPH-L710 version of Samsung Galaxy S3, as an over-the-air update (OTA). However, if you are interested in rooting your Sprint Galaxy S3, which has already been updated to the official Android 4.1.2 Jelly Bean firmware, then you came to the right place. In this tutorial, we will explain you step-by-step how to use Chainfire’s “CF-Auto-Root” tool, in order to obtain root in no time. Don’t worry! Our good friend from XDA developers managed to optimize its rooting tool to support the latest Android versions, so it will definitely work on Android 4.1.2 Jelly Bean and other future firmware.

As you might know, the South Korean multinational doesn’t allow any unauthorized procedures to be performed on their products, which means that once you’ve flashed the rooting files on your Galaxy S3 handset, you will void the warranty. However, if you want to revoke its warranty then you will need to flash an official Android firmware back and the flash binary counter will return to its default state. In case you want to send your SGS 3 to an authorized Samsung service for repairs and you don’t know if the warranty is voided or not, then you should use the comment box below and we will help you clear this out.

Before starting the procedure, you need to make sure you read the preparation instructions as follow:

  • The information available in this post is designed only for your Sprint Samsung Galaxy S3 SPH-L710. We strongly recommend you to not use the files in this tutorial for any other device, as you may permanently damage or brick it. To be sure that you have the right device go to “Settings> About Phone”.
  • As you will need to connect your phone to your PC, you have to download and install the USB Drivers for your Galaxy S3 from here.
  • If your smartphone is running on Android 4.0 or later, go to “Settings” > “Developer options” and make sure the “USB debugging” mode is enabled. However, if your device is running on Android 2.3 or earlier, you can enable the debugging mode by navigating to “Settings” > “Applications” > “Development”.
  • Before starting the process, make sure you create a backup of all your important data stored on your device’s internal memory. I personally use the “Helium” backup tool, but you can use any other similar application, like “My Backup PRO” or “Titanium Backup“.
  • Check out this tutorial, if you want to learn how to keep your “Contacts” save once and for all.
  • Make sure your handset’ s battery level is over 80%, if you want to avoid any unpleasant interruptions during the rooting process.

If you are sure to meet the requirements presented above, then you are ready to go further with the procedure.

How to root your Sprint Galaxy S3 SPH-L710 on official Android 4.1.2 Jelly Bean firmware 

  1. To start, you need to download the “CF-Auto-Root” tool for your particular Galaxy S3 SPH-L710 from here. Extract all its content into a separate folder on your Desktop.
  2. To flash Chainfire’s rooting files on your S3 device, you will need Odin v3.07, so make sure you don’t forget to download it. You can find it here. Extract the zip file into a new folder, created on your Desktop.
  3. After you completely power off your device, you should boot it into “Download Mode”. To do so, you need to press and hold, at the same time, the “Volume Up”, “Home” and “Power” buttons until an Android logo is displayed on the screen.
  4. Press the “Volume Up” key once again, to confirm that you really want to boot your device into “Download Mode“.
  5. Go to your computer and run the “Odin.exe” application as an admin. Right-click on the executable and use the “Run as administrator” option.
  6. Use a proper USB cable, while still in “Download Mode”, to connect your S3 to the computer. If the connection is successful, Odin will display an “Added!!” message and the “ID: COM” section will turn blue. However, if the message is not shown, you should try to connect your device using another USB port or to install the Samsung USB drivers once again.
  7. Press the “PDA” button, in Odin and load the “CF-Auto-Root-d2spr-sphl710.tar.md5″ file, you’ve extracted at step 1.
  8. Make sure that the “Auto Reboot” and “F Reset Time” options are enabled. The “Re-Partition” box must not be checked, so make sure you verify this option before you proceed any further.
  9. Now you can press the `Start` button and wait for the flash to be completed.
  10. After the installation is complete and a green “PASS” message is displayed in Odin, you can safely unplug your smartphone from the PC.

If you followed carefully the above steps, then you have successfully installed the Android 4.1.2 Jelly Bean firmware on your Sprint Samsung Galaxy S3 SPH-L710. This will allow you to install and explore any application that requires root permission, flash your favorite custom ROMs, overclock your device’s GPU and many other interesting tweaks.  We hope that the tutorial proved to be helpful and in case you have any queries, please do not hesitate to use the comment box below!
