Today i found a application called Xolo Root under system folder on my dad’s Xolo Q3000.
Xolo Root App:
By using this application you can root your Xolo Device officially but with some Terms and Condition.Also it required internet connection to root your device so it may save your Device IMEI,Serial no etc on their server.Xolo Root app was hidden in the application drawer.You can launch Xolo Root application by dialing *7813294#. I found this number by De-compiling it.
I think Xolo Root application may be shipped with all newly launched devices .
