Here is how you can easily root your Galaxy S3 and let it enjoy the world of freedom –
WARNING – Before you jump into the real action, please go through the following
This method is applicable for Samsung Galaxy S3 GT-I9300 (International model)/Jelly Bean 4.1.2 only so do not attempt this on any other phone model
Beware of the fact that rooting voids phone’s warranty
Rooting always carries a risk of bricking the phone so be careful and do not blame us if anything goes wrong. You should know clearly what you are doing and be prepared for any adverse event. In case of any adverse outcome, do not panic, Google is your friend always. Besides, there are several forums and kind-people out there online to help you out in almost every possible problem.
Recharge phone’s battery to at least 3/4th before starting root process (preferably it should be fully charged)
Backup your important phone data before rooting as it might get lost during the process (very rare, only possible if the phone gets bricked and it has to be factory reset)
A Windows PC, Samsung Galaxy S3, USB data cable, CF Autoroot file and Odin
Samsung phone’s USB drivers must be installed in your computer – usually drivers get installed automatically when phone is connected with the computer for the first time and also if Kies software is installed in computer. However you can also download and install them from Samsung’s official website
Disable anti-virus software in your computer (as it may interfere with the rooting) and also close Samsung Kies if it is installed and running in computer.
Check that USB Debugging option is enabled in your phone (it can be found under “Settings – Developer options”)
Enough! Now you are ready to go, follow the steps carefully
Download Odin from here – extract the zip file in computer
Download CF-Autoroot (zip file) from here and extract its contents – a .tar.md5 file will be extracted
Launch Odin as administrator (right click on odin exe file and click “Run as administrator”)
Switch off your Samsung Galaxy S3 and then start it in “Download mode” – in switch off condition press and hold Volume down + Home + Power buttons for a few seconds – phone will boot up with a warning – press Volume Up button – phone will show download mode screen
Now connect the phone with PC via USB data cable – wait for a while as Odin shows the “Added…” message
Now click “PDA” button in Odin – browse and select the CF-Autoroot (the .tar.md5 file you extracted earlier)
Select the options in Odin as shown below
Everything OK! Finally click the “Start” button at Odin – Odin will start the process – a series of messages will appear in Odin message box – wait for a while until the rooting process finishes – phone will reboot – if everything goes right a success message will appear in Odin after few minutes – now you can disconnect the phone from PC
After rooting, first phone reboot will take some time – wait for it and done! Enjoy your unlocked SGS3, free from Samsung’s shackles. To check whether the rooting was successful, just install Root Checker app from PlayStore and run it – select “Verify Root Access” – after a while a message will show up “Congrats this device has root access” if the rooting was successful. If the rooting was not successful in first attempt then try again a few times.

This method will not install any custom recovery in your phone (which is required to install a custom ROM). However you can flash any recovery (like ClockWorkMod) when required later on.
If Odin does not recognize the your phone then re-install USB phone drivers and try again
