Root Galaxy S3 on stock JB 4.2.2 XXUFME7 Firmware

If you need to root your Galaxy S3 I9300 on stock Android 4.2.2 Jelly Bean XXUFME7 firmware, then I will give you a helping hand as this step by step guide will teach you how to easily and fast unchain the system on your smartphone. This guide can be completed in just a few minutes as Odin will be used, so you have all the reasons for trying the same.

Of course since we are talking about a root operation, be careful in what you apply on your Samsung Galaxy S3 because you don’t want to damage or even brick your device. That’s why you shouldn’t perform things by yourselves and without consulting the lines from this tutorial.

Even though we will be using Odin, which is an app developed by Samsung and usually used on official flashing operations, the root process is an unofficial method. So, rooting the Galaxy S3 on stock JB 4.2.2 XXUFME7 OS has nothing to do with Samsung or with Google – you will complete an unofficial operation so the warranty of your phone will get voided. Of course, if needed you can restore the warranty but you will have to downgrade to stock Jelly Bean OS, update with an official firmware, or un-root the system by applying an un-root operation – then the bootloader will also be relocked.

The root procedure should be applied only if you want to obtain more from your SGS3. As you know, by gaining root access you are also gaining access to the internal system of your device, so you will be able to remove in build programs, install new apps, customize and optimize the OS, improve the battery life and so on. Furthermore, the root operation is the first task to complete when looking forward in installing a custom recovery image or updating with a custom ROM firmware.

As you can see having a rooted smartphone is a must have, especially if you want to change and improve the Android experience and the default performances. But don’t forget that the warranty will get void, this being the only negative aspect related to the root access. Also, be aware as on a rooted system you will not be able to receive OTA updates – you will be able to flash the official firmwares only by using manual methods.

In order to complete this step by step guide you will have to use a Windows running computer, your Galaxy S3 on official Jelly Bean 4.2.2 XXUFME7 Firmware and the phone’s USB cable. Then, as a recommendation, you should deactivate the Firewall and antivirus protection from both PC and smartphone because the security tools might interfere with our guide. Furthermore, you need to enable the USB debugging option on your phone and charge the battery of your handset, especially if you notice that there is less than 60% power left.

Don’t forget to backup the SGS3 data. As mentioned the root operation isn’t official so your data might get corrupted – erased. That’s why you should save everything you need, starting from contacts, messages, market apps and ending with internet settings and EFS folder.

Keep in mind the fact that this tutorial is compatible with the Samsung Galaxy S3 model number I9300; furthermore, your smartphone should be featuring the latest and official version of the Android system, the Jelly Bean 4.2.2 XXUFME7 software – else this method won’t work, or worst you can brick your device while trying to root its internal system.

How to Root Galaxy S3 on stock JB 4.2.2 XXUFME7 Firmware

  1. First of all, download Odin and install the tool on your computer.
  2. Then, download the rooting package from here and unzip the file on your computer – preferable on desktop.
  3. Also, download and install Samsung KIES because you need to flash the Galaxy S3 drivers on your PC.
  4. Now, on the computer run Odin.
  5. Turn off your handset and reboot it in download mode: press the Volume Down, Home and Power buttons at the same time.
  6. Take the USB cable, plug it in and connect the smartphone with the computer.
  7. Now, take a look on Odin as the program needs to identify your Galaxy S3: the “added” message must be displayed and the ID:COM section should be yellow or blue.
  8. If not, you should close Odin, unplug the USB cord and re-install the S3 drivers on the PC; then repeat the steps from above.
  9. If everything is going as planned, then, from Odin select “PDA”.
  10. Pick the root file from the desktop.
  11. On Odin don’t make any other changes; the re-partition box should be unchecked.
  12. Click on “start” – the root operation will begin.
  13. In the end, the “pass” message will be displayed on Odin.
  14. Then, you will be able to disconnect the devices and reboot your handset – you are done.


Take note that if Odin gets stuck, you need to:

  • Close the program.
  • Remove the USB cable.
  • Force restart your smartphone.
  • Re-flash the SGS3 drivers on the computer.
  • Run Odin and complete the steps from the root operation.

Also, if in the end, your phone will get stuck in a boot loop you will have to:

  • Reboot in recovery mode – press the Power, Volume Up and Home buttons.
  • From recovery you will have to select “wipe data factory reset” and “wipe cache partition” – that’s why a backup was recommended.
  • Then, return to recovery mode menu by selecting “+++go back+++”.
  • And finally choose “reboot system now”.
