How to Root AT&T Samsung Galaxy SII (S2) Using Odin [Step-by-Step Guide]

We have already covered the rooting of the Samsung Galaxy SII (S2) is some earlier articles through several methods including using the insecure rooted kernel flashing which is perhaps the safest and easiest method to follow. Another advantage is that it keeps the device in almost stock condition except for the root (only SU binary, Busybox and CWM are installed). Now here is a method very similar to the mentioned above but for the US users of the Samsung Galaxy SII (S2) that are on the AT&T variant of the device.

Note: Rooting, Jailbreaking or customizing your device can be risky, and you may end-up bricking your device! Follow the instructions posted here at your own responsibility as Inspired Geek will not be responsible for any damage to your device.

Required Downloads

- Download the ODIN file and then extract the .zip file.

- Download the pre-rooted kernel for the AT&T Galaxy S2 from here and extract the archive using a tool like freeware 7 Zip.

- If you do not have Samsung’s KIES 2.0 installed, download and install it. Correct USB drivers must be installed, so that programs can communicate with the device. Reboot computer after KIES installation.

Procedure

Step 1: Make sure that your device is in USB debugging mode: Settings -> Applications -> Development -> USB debugging.
Step 2: Reboot your device into download mode. To do so: Turn the device off, then power it on again by pressing and holding Volume Down + Home + Power simultaneously.
Step 3: Start ODIN.

Step 4: Connect the device to your computer using USB.
Step 5: Wait a few seconds, the ODIN screen will show that a device is now connected
- Make sure that in ODIN nothing is checked, except the "Auto reboot" and "F. Reset Time" checkboxes.
- Press the "PDA" button, and select the the extracted tar file (from Required Downloads section above).
- Press "Start". ODIN will now flash the kernel, and the device should reboot.

- Now remove the USB cable from your device when you see the green Pass in Odin.

Step 6: After the device reboots you will have full Root access on your Galaxy S2 (SII)!
