I have the same problem.
Framaroot does not work. The phone has a Qualcomm Snapdragon 200 quad-core processor. Framaroot should use the Gandalf exploit to root the phone. But when I try Framaroot, Gandalf does not appear in the list of available exploits. Other people have experienced the same thing.
Also tried Kingo Root, again without success. I received a form letter from Kingo saying they will get back to me when they have a solution. I am not hopeful.
Any help would be appreciated.
