Steps to Root your Samsung Galaxy S II (How to)

There are many tutorials available to find on many sites or forums. Here is just one of them to make sure you can't find one. So, lets begin to root your Samsung Galaxy S II.

First, here is a list of things you will need:
  • A fully charged Galaxy S II
  • A micro USB connection cable
  • A Windows PC (I have no experience with doing this on a mac, so for now the guide will only cover Windows)
  • The PC will need to have the USB drivers for the Galaxy S II installed:
  • If you simply connect the Galaxy S II to the PC with the micro USB cable it will install them
  • To be very sure your device will be recognised by Odin connect twice - once with USB debugging enabled, and once without - different drivers are installed depending on the status of debugging (USB debugging is in Settings --> Applications --> Developement)
  • If you're still having no luck try also installing the latest version of Samsung's Kies
  • A copy of a program called Odin  - you can download it here
  • The right version of Chainfire's Root kernel
  • To work out which version you need go into Settings --> About Phone in your Galaxy S II, and scroll down to where it says "Kernel version". You will see a string something like this: 2.6.35.7-I9100XXKI3-CL571576. The yellow bit after the XX is what you're looking for.
  • Once you've found that bit head to Chainfire's thread at XDA-developers here, and download the correct file. The easiest way to find it is hit Control+F and then enter the text from your phone that corresponds to the yellow text in our example above.
Alright, now we've got all those things assembled, it's time to void your warranty! Here are the steps you need to follow:

1. Unzip the CF-Root zip that you downloaded using the instructions above
2. Start Odin, it should look like this:

3. Click the button "PDA", shown in the picture below. Navigate to the file you unzipped from the CF-Root zip and select it (it's file extension will be .tar)

4. Make sure "Repartition" is NOT checked

5. Power down your phone, and then put your phone into download mode. Do this by simultaneously pressing and holding the volume Down and Home buttons, and then while holding these buttons down press and hold the power button down until this screen appears:

6. Follow the instructions on that screen and press the Volume Up key to proceed into download mode, you will be greeted with a screen that looks like this:

7. Connect your phone to your computer with the USB cable, after a few moments Odin should recognise the device and look like this:

8. In Odin press the Start button
9. Odin will flash the kernel to your device, and at the end you should see this in Odin:

10. Your device will reboot, disconnect the device - congratulations! Your Galaxy S II is now Rooted!

Done ! If you feel compelled to show your gratitude with a financial reward, please  go here and make a donation to Chainfire for his excellent work.
