My YU Yureka is stuck at the Cyanogen logo. I was just using Chrome with very low battery when it suddenly restarted and got at stuck at the Cyanogen logo. I don't have any backups.

I've been trying to start the phone in safe mode but none of the methods I've tried have been working.

Kindly suggest a way to start my mobile. If you can't help me I'll take it to a service center, would they be able to recover all data completely without any losses?

Kindly suggest solutions/sites/videos that may be helpful to me.

Device model: AO5510  

Cyanogen OS version: 12.1  

Android version: 5.1.1
