Ah, the penny dropped. Brilliant. There was a second password of course, not the screen lock but the previous owners IT password. I downloaded the latest desktop software after the previous version would not access without a password. I then did the 10 incorrect entries, the phone reset and then I turned on your program and told it there was not password. Everything worked perfectly after that. It got rid of the IT permissions and I uploaded the latest OS to make sure everything was fine. Many thanks, a good workaround a stupid problem.
