Stuck on "checking connection" screen - Micromax Canvas A1


AC Question

My Micromax canvas A1 mobile is on android-6.0.1 version. Today I tried to factory reset my mobile and completed reset then i rebooted my mobile and it went through language selection screen -> Done. Selected wi-fi connection and clicked on next,->Done. Then it got stuck on "Checking connection..." screen. I tried with mobile network as well, but no use.

Tried restart no luck. Tried factory reset again still facing the same problem.

How to fix this ?
