Re: Pleas help add root to system.img

You can download superuser.zip or supersu.zip from xda, the zip used to install it with cwm, unpack it, and add the files inside to the correct location, add the permissions, and vuala, you have the device rooted. To check the permissions needed take a look at updater-script file inside the zip, it contains a edify script and looking on it you will see the permissions needed for the files.
