Prompt [Q] ROM Flashing QMobile Noir Z3 with Gionee Elife E5

Dear All,
I am using a mobile name QMobile Noir Z3 which is duplicate copy of Gionee Elife E5 according to my research. Both are MTK6589T same processor and other hardware specification along with the Graphics card.

I am trying to flash the custom ROM of Gionee Elife E5 which I downloaded from a trusted website on my QMobile Noir Z3 but I am not an advance user so I am not quite sure that will work correctly or not. That why I need some help from an expert. I will be very thankful.

I can not post any link because I am new user. kindly check both mobile specifications.

I will be waiting for a positive and helpful reply. Thanks in advance.
