Default [Q] Rom for Huawei G730

We stay in India and My brother just bought Huawei G730 phone from china.
The phone has hell lot of restrictions and I am not able to open up play store in that and configure my gmail account.

Is there any way I can install some custom ROM on this phone and where to find this custom ROM etc. I have a very less information about this.
If there is any post describing this whole process, it will be great help.
