Unfortunetly i couldnt find a specfic thread for what your asking for. search a bit here http://forum.xda-developers.com/show....php?t=2492888
I only found one useful root thread for your device, but I'm afraid its outdated and may not work on 4.4.2 kit kat. You can ask in the thread tho, perhaps someone has a suggestion.
Again, ask before you try anything. I think its an outdated method. But I could be wrong.
Otherwise you'll need to ask here, since there's no section for your specific device.
>*Android Development and Hacking*>*Android Q&A, Help & Troubleshooting
Edit: an XDA Assist colleague also suggested to read up on Towel Root. Its relatively new, but may work for you. You can ask further questions about it and research it here....
