I have a brand new Lumia 640 that I got with Windows Phone 8.1 Update 2 and Lumia Denim. I went and got the Windows 10 Upgrade Assistant from the Store believing that it would put me on the latest build of Windows 10, 14393. Instead, it stuck me on 10586, and now, when I go to the settings app, 14393 shows up and will download in a normal expectable time, but fails with a error code after going through the "Preparing to Install Updates" step. I have tried different Wi-Fi networks, I have tried soft resets, I have tried plugging it into power, I have tried using the WDRT to force a install (it just wants to revert back to WP8.1), and now I am out of ideas. I am in the middle of a hard reset right now. Any help would be appreciated.
