These are the instructions to root the Samsung Galaxy S3 GT-I9300T operating on the Android 4.0.4 Ice Cream Sandwich software update. The guide uses the CF-Auto-Root tool by popular hacker and developer, Chainfire, and the Odin flashing that which was never officially released by Samsung.

The CF-Auto-Root file by Chainfire in this guide for the Samsung Galaxy S3 smartphone is based on the Android 4.0.4 Ice Cream Sandwich software update and the IMM76D.I9300TDUBLH1 firmware build number. You don’t need the same IMM76D.I9300TDUBLH1 firmware running on your Samsung Galaxy S3 smartphone, but you can use that information as an indicator for your own. It is true that some of the Samsung smartphones and tablets won’t boot the older image files.

Rooting the Samsung Galaxy S3 GT-I9300T running on Android 4.0.4

  1. Install the universal ADB Driver on your Windows PC before you do anything else, so the Samsung Galaxy S3 can connect to the computer and the Odin flashing tool without any worries.
  2. Extract the Odin flashing tool and the CF-Auto-Root files on the desktop: Download them from the links above and then open your default downloads location which is usually the ‘Downloads’ folder. Now click and drag your Odin and CF-Auto-Root files over the desktop.
  3. Right-click over the files and choose the “extract here” from the menu.
  4. Choose to switch off the Samsung Galaxy S3 smartphone from the Device Options menu and reboot it in the download mode: Volume Down + Home + Power buttons simultaneously.
  5. Connect the Samsung Galaxy S3 to the computer with the USB cable.
  6. Wait for a few moments until the drivers start working and then look for the green ID: COM port from the Odin user-interface. No color means no connection and that means you need to get the drivers working. Try downloading the Samsung USB Drivers as an alternative.
  7. Click the AP or the PDA button from the Odin user-interface and browse the desktop of the S3’s CF-Auto-Root tar.md5 file.
  8. Click the Start button without changing any of the default settings from the Odin flashing app on the computer.
  9. Wait for a few minutes and then check your Samsung Galaxy S3’s display for when it says it’s restoring the stock recovery, cleaning up and then it’s about to reboot in about 10 seconds.

The Samsung Galaxy S3 smartphone should now reboot in the recovery mode and your SuperSU will be installed and enabled on the device. Any Samsung Galaxy S3 that does not reboot to recovery mode will need to get in recovery manually by using the hardware key combination for recovery mode. You can get in recovery mode on the S3 by pressing and holding the Volume Up + Home + Power buttons at the same time when booting the smartphone. It will not work unless it is already off first.
