Hi, I have used this programme in the past to unlock a k600i and a k800i with no issues. Now I have reinstalled the programme and I can't identify a S500i. I have tried 3 USB cables to no avail. I have now tried to get my K600i identified and that wont work either. I am at a loss and can think of no reason why this would happen as I'm following the same procedure used before. Anyone ?
