    My Microsoft Lumia 535 Dual Sim has just updated from Windows 8.1 to Windows 10 technical preview. I try to enter my PIN and unlock it but it doesn't work. I keep trying, then I search up the problem and it says leave your phone alone for 2 hours. So I leave it alone for 2-4 hours. I open it up, and instead of letting my type in my pin, it says

    "You've entered an incorrect PIN too many times.

    To try again, restart your device."

    I restart it again and again and even hard reboot it, but it still remains. What do I do? Do any of you have the same problem?

    I had similar problem with bitlocker encryption, I've send tweet to Gabe Aul and got response to use Windows Device Recovery tool. With it I went to 8.1. and then to 10. Try to tweet Gabe Aul, or Insider before doing hard reset or rolling back to 8.1.

    OK, thanks! I restored my phone to 8.1 with Windows Recovery Tool and now it is working perfectly!
