Hi,
I'm facing the same issue, my phone hangs up at boot loading screen, and it would again restart, all by itself. So its kinda stuck in this endless loop. I downloaded SUS and on using it the only suggested outcome is that I factory rest my phone, which would result is loosing all my data.
Since i can access my phone, IS THERE ANY OTHER WAY THROUGH WHICH I CAN BACKUP MY DATA...?

It would be really helpful if you reply soon, i'm struggling with my phone since morning.

If the phone is in a continuous boot loop,you cannot backup.
