I have the same problem but with a twist. I uninstalled avast anti-theft with the intension of inserting a new sim into the phone ( Galaxy S3). On inserting the new sim i got the message stolen phone!! and was prompted for password. I enter the password ten times and it does not work. Reinserted my old card - same story - password not responding. Then i pressed the send SMS for temp password, waited for the sms on the friend phone but no sms, 10X!!

Can someone help?
