I use a Samsung Galaxy S2 (sadly), and thanks to Google, I was able to get the Official Android 4.1.2 XWLSW JellyBean firmware. But it wasn’t rooted.
The task now is, How do I root my Samsung Galaxy S2 running Jelly Bean OS?

Before you begin, you need these downloads
- Your Samsung Galaxy S2 USB drivers. You can download Kies Mini for this.
- Odin 3.0.7.
These are also VERY IMPORTANT!
- Make a backup of all your important data before following the guide. How do I backup my data? Check out Toms Guide
- The Galaxy S2 should be factory unlocked and not locked to any particular carrier. Find out how to do that here.
- Ensure the battery of the tablet is charged more than 80 per cent. Do you want to find out how to check the battery level of your phone as well? Oh don’t be silly
- Enable USB Debugging Mode on the phone. How do I enable USB debugging on my phone? This humorous Youtube video courtesy of AndroidLifeStyle should help.
The Root Kernel file works only on Samsung Galaxy S2 I9100 running on Android 4.1.2 Jelly Bean firmware. Applying this on any incorrect variant will brick the device. Verify the model number of the Galaxy S2 by navigating to Settings >> About Phone.
Steps to Root Galaxy S2 I9100 Running on Android 4.1.2 Jelly Bean Firmware
culled from Honai of Android
- Extract and run Odin 3.0.7
- Reboot the device into Download Mode by first shutting it down then pressing and holding Volume Down + Home buttons together and then the Power button until the device turns on. Now press the Volume Up button to enter Download Mode.
- Launch Odin on your PC (preferably with administrative rights)
- Connect the Galaxy S2 to the computer using USB cable while it is in the Download Mode. Wait until Odin detects the device. When the device is connected successfully, the ID: COM box will turn yellow (or blue) with the COM port number. Additionally, the successful connected will be indicated by a message saying Added. If Odin fails to detect the device then re-install USB driver.
- In Odin, click the PDA button and select the Root Kernel file. (In our case, our Root Kernel is Siyah)
- Verify that AUTO REBOOT and F.RESET TIME checkboxes are selected in Odin. Also, ensure the RE-PARTITION option in Odin is NOT selected.
Before you continue!!!
- DOUBLE-CHECK that these options are selected. If you are sure, then click START in Odin. The installation process will now begin.
- Once flashing completed, your phone will restart and soon you will see a PASS message with green background in the left-most box at the very top of the Odin. You can now unplug the USB cable to disconnect your device from computer.
DO NOT UNPLUG THE CABLE UNTIL YOU SEE THE PASS MESSAGE, EVEN IF YOUR PHONE HAS COMPLETED THE REBOOT PROCESS.
If you followed these steps meticulously, your Samsung Galaxy S2 I9100 should be running on Android 4.1.2 Jelly Bean firmware is now rooted successfully. You may now install any app that requires root permission.
You will now notice that there are two extra apps installed automatically. What are they?
