Retrieve stolen phone using Cerberus and bash

So my phone got stolen and I have Cerberus installed on it as a system app. The phone got wiped and I can't do much with the app right now because it requires location/phone etc. permissions to be turned on, (which I forgot to do).
I'm able to open up a shell command via Cereberus.
I've tried typing in

Code:

---

su

---

but the response I get is -

Code:

---

/system/bin/sh: <stdin>[4]: su: not found

---

So I think the root's got messed up.

Does anyone know any commands that could help me find the location of the phone?
