I'm totally new to rooting and I would like to simply have root access to my phone. I don't want to do any customization whatsoever to the insides of it. Is this doable? I mean like, in terms of a PC, I want to simply give my limited user account an administrative privilege.
Sorry if this seems weird and all but I'm unfamiliar with these grounds.
If it makes answering a little bit easier, my phone is an Xperia Active and here's the information I can find inside Settings > About.
For example, I only want to change the default media sounds stored inside the internal memory. Things like that.
