My galaxy m21 unexpectedly restarting continuously

Boot your phone in safe mode to check if a third-party app is causing the problem. If the phone doesn't restart in safe mode, it indicates that an app is the culprit. Uninstall recently installed apps one by one to identify the problematic one.

Backup your data before it's too late. To turn on the phone forcefully, press and hold power button and volume down button.

After that try factory reset.
If the issue still persists, try installing firmware whose process I have explained in my post(link below):
