This is strange. I'm running the latest Technical Preview of W10M on my Lumia 1520, and have decided I want to revert to WP8.1.
I believe the way to do this is to use the Windows Device Recovery Tool, currently at V3.1.5.
The WDRT installs just fine. When I run it and plug in my phone, it correctly identifies it as a Lumia 1520, and my phone correctly asks permission to let its USB port be used (which I OK, of course).
WDRT says "Please select device to continue" and I click on the picture of the Lumia 1520. At that point it goes to the "Reading device information" page and just sits there forever, showing the spinning circle and "Please wait".
I've tried rebooting the 1520, with and without it already plugged in to the USB lead. I've tried plugging it into a different USB port (USB 2 on the front, USB 3 on the front, and USB2 on the back).
Now I've run out of ideas - can anyone suggest what I should do next?
Thanks.
