iPad Pro keeps repeatedly restarting My iPad Pro(9.7" cellular) keeps restarting and sometimes I won’t even get to finish entering the passcode.

Troubleshooting


I have done a hard reset
I have not installed any new apps
I have updated all my apps
I have done a factory reset
I have updated to the latest iOS 12


But the problem still persists

What could be the problem and how can I fix this?
This could be caused my hardware problem.

Like malfunctioning power Button.

Flaky contact makes it run reset and loop.

Check and replace the hardware.
