The Rooting of device is often done to unleash the potential of your smartphones. Similarly as the Galaxy S3 is very popular device many developers continously develop custom roms of Samsung Galaxy S3. So there are many techniques for rooting S3 but this is good method of rooting it which is using odin and TWRP. TWRP is one of the best custom recoveries which comes with very less chances of causing damage to the device while flashing a custom ROM or a kernel.

Steps to Install TWRP Recovery on Galaxy S3 using ODIN.

Odin is a great tool which allows a Samsung user to do a lot of things on their phone from their PC. Most of the issues with your Samsung smartphone can be solved by Odin/Jodin and you can install the stock firmware using these tools too. It allows you to flash ROMs and root scripts and img files etc. Since this guide is only for flashing TWRP recovery into your Galaxy S3 using ODIN, I’ll only show the steps to install the TWRP recovery.

Lets tie up shoelaces and ready to Go...

Required Items:

1) Galaxy S3 (better if more than 75% charged)

2) Samsung USB Drivers

3) TWRP Recovery File (download latest .tar file)

4) ODIN v1.81 for windows

Step 1: Download the Samsung Drivers, TWRP Recovery and ODIN and Install them.

The Samsung Drivers will be used for communication between your device and the ODIN in your computer system. Without the drivers, your device won’t be able to interact with the ODIN Tool. Install the Samsung drivers in your system once you download them, on successful installation restart your windows system.

The TWRP Recovery IMG file consists of the TWRP Recovery which we will be flashing on our Galaxy S3, since this is what we are flashing we need this, in case you don’t have it then you won’t be able to flash anything. Download it and store it some place where you will be able to remember.

Step 2 : Start ODIN and Boot your Device into Download Mode.

Start the ODIN and you will see a new GUI screen in front of you. After installing and running ODIN, Turn off your Galaxy S3 boot it into Download mode by holding Power + Volume UP button. After booting into download mode you will be asked whether you would like to boot into Download mode or cancel on your screen, you will have to use the Volume UP button to “Confirm booting into Download mode” and volume down in case you don’t want to boot into download mode.

After booting into download mode connect your Galaxy S3 with your PC and on the left side of the ODIN screen you will see Device added showing up, in case it doesn’t shows up re-install the drivers.

Step 3: Installing TWRP recovery using Odin [Final Steps]

Now click on “Bootloader” tab and select the TWRP Recovery ZIP file which you’ve downloaded from the above link and after selecting the TAR or ZIP File, click on “Start”. Once the recovery installation is finished disconnect the device from the device.
