Having root access on your device is usually key to enjoying the vast development available here on XDA. Unfortunately, updating stock firmware usually means kissing goodbye to root access. This is not the end of SuperUser permissions, but merely another step in the rooting process. Although new firmware seemingly revokes your right to root, your custom recovery almost always remains intact.
For those of you needing to root your latest firmware and still have a functional custom recovery, XDA Senior Member Phil3759 has started a universal guide to rooting nearly all devices running ICS. What started as simple guide for Samsung Galaxy S2 owners to achieve root without the need for custom kernels has grown to include various root methods that span across many devices. The guide also includes different versions of SU and Odin to suit individual needs.
If your latest firmware has taken away your beloved root access, head over to the original thread and give these methods a shot._________
