How to Root Samsung Galaxy S3 GT I9300 [Tutorial]

Rooting Galaxy S3 I9300

Nowadays developers are so smart that even prior launch of an Android Device they find out a way to root it. We have a similar story here with the mighty Samsung Galaxy S3 I9003. As you are aware that its just been a while that Samsung had launched Galaxy S3 and Android developer Chainfree has discovered a way to root it already.“Chainfree” is an Android developer at XDA forum and has shared an easy and working guide to root Samsung Galaxy S3.According to him rooting Samsung Galaxy s3 was a piece of cake as Samsung has itself made it easy for developers to unlock the device. This guide is tested by him on candidate firmware XXALE8 only. So we would recommend you to try this guide only if you have the device with firmware version XXALE8 as we believe that Samsung can make changes to the new firmware. Also please note that we aren’t to be held responsible for any damage occurred to your device by following this guide although it’s very unlikely to happen if you follow these steps carefully.

Before you begin:

  • Rooting your phone will void the warranty of your phone.
  • As of now, we had tested this trick on the firmware version XXALE8. We are unaware of the consequences of implementing this trick on the new firmware (if it exists).So please confirm your firmware version by going into Settings>About Phone.
  • Also make a backup of  your important data including messages, contacts and important applications. You can use your Google account to synchronize your contacts.
  • Your mobile should be charged to at least 50%.
  • Up next, install all the required Samsung USB drivers which are required to connect your mobile with PC. We’ll suggest you to install KIES 2.0 which will automatically install all the required drivers on your PC. 


Step by step procedure to root Samsung Galaxy S 3 permanently:

  • Download mode in samsung Galaxy s3First of all download insecure kernel zip and ODIN from download section on your computer and extract them somewhere on your computer sepratelty.
  • Now pick up your Galaxy S3, switch it off and restart it again into download mode. For entering into download mode, press the Volume Down, Power on and OK button simultaneously. Alternatively, you can take the help of the side by picture.
  • Now on computer side, run the ODIN from the extracted folder and while your phone is in download mode, connect it to the computer. After connecting it, you’ll see that Device ID field will turn yellow. This means that your phone is detected by the ODIN.
  • Now on ODIN interface, go to PDA option and navigate it to the “.tar” file we extracted from insecure kernel zip in first step.
  • Make sure that only “f.reset Time” and “Auto reboot” option are checked. Uncheck the others if they are checked in.
  • Up next, hit start button on ODIN and wait until your mobile reboot. This will flash insecure kernel in your Galaxy S3.
