I've looked everywhere in the forums for an issue with the Nokia Software Recovery Tool, but a lot of people have been getting problems with their phones for downgrading from DP for 8.1 to 8.0 and trying to do the Cyan update. My problem is strange... My computer (self built rig running 8.1 and fully up to date) can detect my Nokia Lumia 1520 and I can even use Windows Media Player or the Windows Phone App from Microsoft to transfer to and from the phone all of my files, but the Software Recovery Tool cannot recognize that my phone is connected at all. I have used the Hard Reset method of shutting it down and plugging the phone back into the computer when the Tool prompts that option and still nothing. It will take forever (~5 minutes) to boot back on and the Tool doesn't recognize it still. I've uninstalled, re-downloaded the up-to-date Tool, re-installed the Tool, and same thing happens... No go. Can anyone help me with this situation, and has anyone else experienced this as well?
