Default [Q] Have few question about my Lenovo K900

Hi all Tech Geeks,

I am a beginner in this forum. I have few questions, and model I am using is Lenovo K900.
My questions.
1. Can I update to Android 4.4? I donít see any install pushed from Lenovo side.
2. Can I root my phone?
3. As per my understanding rooting customer ROM is required. Is the customer ROM available, if yes, can someone please give me the link?
4. If I want to root, could someone please tell me how to do, what is the step by step procedure? As am new to this, I really donít have any idea how to do.
Awaiting for your reply and much appreciated and thanks in advance.
