I hate to be the bearer of bad news but phone freeze is pretty much the end of the line. That is a
security feature in the base firmware. If a
security code is entered incorrectly too many times, the phone completely locks up. At that point, it is pretty much useless.
Samsung has implemented this so that you have to send it back to them.
Unless you know someone that can reflash the main firmware, its bricked.
Please be fair and at least rate as helpful, because there really is no "fix ya" solution available for phone freeze.
