    Downloaded latest insider build on my 640xl, now my phone won't switch correctly. Get a display on my screen saying ( This device has been locked for security reason. Connect your device to a power source for at least two hours then restart it to try again ). I tried this and unfortunately it has not worked. My phone just keeps switching its self on and off intermittently. When I'm trying to attach it to my computer it says this phone is locked and that I have to use a password unlock it but im not able to do this.

    I fear you will have to use the WDRT and reset the phone.

    First, it needs power and if the battery goes flat while you try and fix it that is another problem. So plug it into the charger and make sure it has juice.

    Catch it between boots, meaning when it shuts off and before it starts again.

    In that moment, Hold the Volume Up button until you see the Lightning Bolt and Gear screen. THEN connect to the computer and try WDRT.
