[Q] How to get out of Micromax Soft bricked topic

Well I was modifying vold.fstab file. I think I didnt swapped properly. I am stuck in Android loop. My phone is Micromax Canvas fun A76.
It does have download mode unlike samsung where using odin we can flash cwm recovery. I am in stock android recovery.
I tried flashing through Sp tools but i dont have a valid scatter file. I tried giving in Service center but they dont know what to do.
