  ROOT TELUS GALAXY S3 LTE GT-I9305T

Before you begin with guide instructions below, make sure your android device is adequately charged — at least 50% battery of the device.

  STEP 0: CHECK DEVICE MODEL NO.

To make sure your device is eligible with this, you must first confirm its model no. in ‘About device’ option under Settings. Another way to confirm model no. is by looking for it on the packaging box of your device. It must be GT-I9305T!

Do not use the procedures discussed here on any other Galaxy S3 (including the Galaxy S3 variant at T-Mobile, US Cellular, AT&T, Verizon, Cricket and other International variants) or any other device of Samsung or any other company. You have been warned!

  STEP 1: BACKUP YOUR DEVICE

Back up important data and stuff before you start playing around here as there are chances you might lose your apps and app-data (app settings, game progress, etc.), and in rare case, files on the internal memory, too.

    If you don’t get the Added! message, here are some troubleshooting tips:

    • Make sure you have installed driver for Galaxy S3 as said above in ‘Before you begin..’ section.
    • If you have already installed driver, then uninstall them and reinstall back.
    • Connect using a different USB port on your PC.
    • Try a different USB cable. The original cable that came with your phone should work best, if not, try any other cable that’s new and of good quality.
    • Reboot phone and PC and then try again.

    • Click on the PDA button on Odin and select the  file CF-Auto-Root-m3-m3dv-gti9305t.tar.md5 (from step 1). Your Odin window should look like the screenshot below:
