RE: T20 bought at second hand store. Unable to reset it.
I have verified the version, the 3rd number is 0. I have followed the instructions but I am still unable to log into the phone. When I hold down OK and get the "Reset to factory settings" prompt I hit OK and I get prompted for the user name and password. I have tried to log in via the GUI and I am unable to log in with the password admin.
