[Question] Require Help for s5 custom roms

[burnout19]

Hello everyone, I have recently aquired a galaxy s5 clone that is running a mt6582 chip set. Now the phone has a android kit Kat 4.4.2 JB ROM on it, but I am unsatisfied by the Samsung version of this. What I would like to do is put a new custom ROM onto my phone, but I require
assistance in doing so.

I require help with the following:
- a custom ROM compatible with my phone
- a procedure that will guide me to installing the rom without any errors

Phone specs:
Mt6582
ArmV7 processor rev1 (v7l)- quad core
Msm8974
2gb ram ( 1.8 available)
1,008mb flash memory


All help with this will be greatly appreciated. I will also like to thank anyone and everyone who can provide, or point me in the right direction.
