Exclamation [Q] [HELP] Intex Aqua Superb Network Unlock, Rooting and Custom ROMS

Hello! I have this phone Intex Aqua Superb Dual Sim running on Android Jelly Bean 4.1.2 phone which i recently bought in Qatar hoping that i could use the phone in my country, Philippines. I tried using multiple sims from different network providers, it just says network locked and i am not getting any signal from any of our local network providers. The only thing to make it operational (receive signal) is thru hard resetting via Recovery Menu or Factory Reset. But ONLY the SIM1 works AFTER INITIAL BOOT. When i turn it off, or restart the phone, it doesn't recognize the sim again (network locked). Now, i wanted to know if there are any solutions to this?
I'm guessing that Rooting, Unlocking Bootloader and installing Custom ROMS could fix the problem.
I tried google and i get zero results regarding Rooting Intex Aqua Superb, until now i still can't find anything on the internet that can even relate to fix my problem. I am hoping that you guys can help me out. Thank you!
