How to Root Samsung Galaxy S3 I9300 on Android 4.1.2 [ September 2013 ]

Just a month back Samsung released a minor 40 MB update for Samsung Galaxy S3 I9300 running Android 4.1.2 (  Feels bad stuck on Android 4.1.2 for ages ) , Officially there were no change logs provided for the update but we can assume that it was probably an minor performance  upgrade . As it is with installing an Official software update , My Samsung galaxy S3 was unrooted in this process .

Once again i had to source for the latest CF auto root and Odin to root my Samsung galaxy S3 . In fact i even tried Framaroot which had previously worked on my Samsung galaxy S3 , but after the update Framaroot was unable to root my Galaxy S3 . So the only option i had left was to root my Samsung Galaxy S3 through Odin .

If you had installed the same update , then follow the instructions below to manually root your Samsung Galaxy S3 I9300 using Odin and CF-Auto-Root by Chainfire .
