[PATCH] Install Superuser, Busybox and Rooted Kernel (For Use After Obtaining S-OFF) - xda-developers
The first thing anyone is going to want to do once AlphaRev's S-OFF process is complete will be to get your device properly rooted within Android. I have created a simple update zip which will take care of the following for you:
-Re-install the stock kernel, using a rooted ramdisk (credit jcase).
-Install the Superuser app and su binary in /system/xbin.
-Install and setup Busybox in /system/xbin.
Simply install this patch via CWM and reboot. From there you can proceed to run any root apps you need (such as Titanium).
