Droid Razr HD restarts every seven seconds

[mgosho]

I have pulled the SIM card, cleaned it and blew out the connections.  I hard started the phone, to no avail.  The battery is charged, it's reading as a 90% but it keeps restarting.  Any other ideas other than taking it to the store?

having the same problem, tried putting it in safe mode, but reboots and exits, tried unmarking automatic updates, sorry its not an answer, just feeling your pain!!
