***Update: Please use the New Updated CF-Root method to root Samsung Galaxy S2 (SII) instead of this one which is guaranteed to work on any SGS2 device. Method posted here is older and may not work on older SGS2 devices!
It has been only a matter of days that everyone was talking about the release of the new super power in the Android handset arena, and yesterday news broke out of the XDA forum that Samsung Galaxy SII is successfully rooted based on the insecure XWKDD kernel posted by the Chainfire – an XDA forums member. Successful root has been confirmed by a number of the users in the thread. Basically most of them apparently flashed the insecure XWKDD kernel and then used the SuperOneClick v1.5.5 tool to do the magic!
Now we are pleased to provide the detailed step by step guide for every Samsung Galaxy SII user who wants to root the device (credit goes to Chainfire for this).
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 InspiredGeek will not be responsible for any damage to your device.
- Download the ODIN file and then extract the .zip file.
- Download the XWKDD tar file (NOT extract the .tar file).
- Download and extract SuperOneClick
- 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.
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 VolumeDown + 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 "XWKDD_insecure.tar" file.
- Press "Start". ODIN will now flash the kernel, and the device should reboot.
Step 6: Wait until the device is rebooted
- While still being connected over USB, start SuperOneClick
- And press ROOT.
Step 7: Reboot the device.
Step 8: Done! Now you have a fully rooted SG2!
