Hey, just bought an x3. Updated everything to latest version (non-insider). Everything was working well until I plugged it in to my elite x3 lapdock. The phone wanted to update the docks firmware, it downloaded then failed to install. The message suggested I reset the phone and try again. I did the power and volume down reset and the phone has not come back on since. It will only get to the hp logo then goes black. Have tried wdrt but its different to the Lumia procedure and it wants me to hold volume up as power comes on to display a gear and a lightning bolt picture having no luck with this as the hp logo just goes away and the screen goes black. Any suggestions
