Jul 23 How to root any ICS phone with Universal Root Method

Every Android user loves to enjoy the root access of his device, however whenever a smartphone is updated to stock firmware he loses the administrative access. If you are one of those who have encountered such problem on ICS device then you will be delighted to know that you can get the root access once again via an easy method produced by XDA Senior Member Phil3759.

The highlight of the method is that it is a universal guide that can root any device based on Ice Cream Sandwich. The guide was developed to get the root access of Samsung Galaxy S2 without custom kernels but it supports most devices now.

So are you ready to root your Android 4.0 device? If so charge your battery, do NANDROID back up in CWM and proceed at your own risk, we won’t be held liable for any harm. The instructions are given below.

• Download cwm image for your phone from here or get recovery-clockwork-touch-5.8.1.5-galaxys2.zip if you have i9100 Galaxy S2.
• Place the downloaded CWM zip file on external sd card
• Download the root file from here or here and copy it to internal or external sd card.
• Press volume up, home and power button simultaneously to boot into stock recovery, now select “apply update from external storage”. Now select the cwm image file that you have downloaded in the first step.
• You will get temporary CWM touch recovery interface.
• Select “install zip from sdcard” in CWM and select “choose zip from sdcard” or “choose zip from internal sdcard” and point it to the attached root file.
• It will add SuperSU or Superuser last version apk to system/app, last superuser binary (su) to system/xbin and busybox last version to system/xbin, all with correct file permissions.
• Reboot your phone and you can enjoy permanent root, along with busybox installed on your stock kernel.

The guide is easy to follow and unroot as well. So if you want to unroot your device, follow the same steps, just replace the root file with unroot file. It will delete superuser, su and busybox files.

The aforementioned method is recommended by the developer because it is easy to unroot, works without modded kernels and it is compatible with most ICS devices. But if you want to try any other method, hit the source link below because Phil3759 has listed few other rooting methods there.
