Hi, my phone just is showing this link of support centre and if I restart it comes to the same link.

Hello Shivamgupta1998,

We believe that you may be seeing the restore screen on your iPhone and we're happy to provide direction.

A computer will be necessary to complete the steps from If you see the Restore screen on your iPhone, iPad, or iPod touch to restore the software of your device and return functionality. If you do not have access to a computer to complete those steps, then seeking the assistance of a service provider listed at Find Locations would be the next step to pursue.

Cheers!
