Here’s an updated tutorial for rooting all Galaxy S3 models including AT&T, T-Mobile, Sprint, Canadian, US Cellular, MetroPCS, Cricket, GT-i9300, GT-i9305, and even Galaxy S3 Mini. (It will not work on Verizon S3 as it has a locked bootloader.)
This will work on the following S3 models:
- AT&T SGH-i747
- T-Mobile SGH-T999/SGH-T999L
- Sprint SPH-L710
- Canadian SGH-i747M
- US Cellular SCH-R530
- MetroPCS SCH-R530M
- Cricket SCH-R530C
- Galaxy S3 Mini GT-i8190/GT-i8190N
This root method will work on all Android versions including Android 4.4.2 KitKat, Android 4.3 Jelly Bean, Android 4.1.2/4.1.1, Android 4.0.3 ICS, etc…etc…
Step 1. Power off your Galaxy S3. Then hold down Volume Down, Center Home, and Power buttons together until you see a warning screen like below. Let go of all buttons.
Step 2. Hit Volume Up to enter ODIN Download mode then connect a micro-USB cable from your S3 to your computer.
Step 3. Next, download the appropriate TAR CWM recovery file on our Galaxy S3 CWM/TWRP Recovery page.
Step 4. Next download ODIN zip file and unzip the files.
You should get a folder called Odin3v185 with two files like below.
Step 5. Double-click on “odin3v1.85.exe” to start ODIN program.
Step 6. You should see a yellow-highlighted box with a random COM number. If you don’t see this, you don’t have proper drivers installed. Download and install Samsung Galaxy S3 USB Drivers.
Once you see the yellow-highlighted box you are ready to go, hit the “PDA” button.
Step 7. Find the TAR recovery file you downloaded earlier in Step 3 and choose it.
Step 8. Hit “Start” and it should take about 5 seconds for ODIN program to flash CWM Recovery to your Galaxy S3 and you will see “PASS!” when it’s done. Your phone should reboot.
Step 9. Once your phone has rebooted, download SuperSU zip file and copy it to anywhere on your phone’s internal storage.
Step 10. Power off your phone. Then hold down Volume Up, Center Home, and Power button together.
When you see the Samsung logo, let go of Power button but keep holding down Volume Up and Center Home buttons.
Step 11. You should now be in CWM Recovery. Choose “Install zip”.
Step 12. Choose “choose zip from /sdcard”.
Step 13. Choose the SuperSU zip file you copied over earlier and install.
Step 14. When done, simply reboot.
Step 15. You should see a new app called SuperSU in your app drawer, run it. If you get any messages asking to update binaries or disable KNOX, say “yes” for both. (If SuperSU app freezes, just reboot and try again, it should work the second time.)
Step 16. Verify you have full root by running a rooted app like Titanium Backup app. If you see a Superuser request window like below, congratulations! You have fully rooted your Galaxy S3!
Q: Will this erase any apps or settings on my Galaxy S3?
A: No, this root method does not touch your apps or settings, it simply installs custom recovery such as CWM or TWRP then root using SuperSU zip file.
Q: I don’t get CWM Recovery, I just see stock recovery after flashing CWM with ODIN!!!
A: On some S3 models, there is a script that overwrites the recovery you flashed. If you get stock recovery, just simply flash recovery again using ODIN, as soon as you see “PASS!”, pull the battery before your phone reboots. Then do the buttons to get into CWM recovery and do the rest of the root instructions.
Put the battery back in and boot straight into CWM recovery, then when you reboot in CWM recovery, it will ask you to disable recovery script. Do that and you should be good to go.
Q: I am having trouble with Knox!?!
A: After rooting, open up SuperSU app, it will ask you to disable Knox, say “HELL YES”.
Q: How can I thank you for your tutorial?
A: I don’t take donations but if you could PLEASE subscribe to my Zedomax YouTube channel, that would help me greatly and thank you!
