com.google.settings has stopped Micromax Android one

I am using Micromax android one with Android 5.0.1. Couple of weeks ago, few of my applications stopped one by one. Only two things I was able to do was calling and Whatsapp, probably waiting for their turn to stop. Recently it started showing Unfortunately, com.google.settings has stopped. I tried to do a *Hard Reset*. On rebooting itself it started showing Unfortunately, com.google.settings has stopped. And now I am able to do nothing with the phone. Highly appreciate any help.
