Why won't Windows Phone Recovery Tool recognize my phone?

[Windows Central Question]

I installed Windows 10 Mobile on my Nokia Lumia Icon last night. There were some problems with the install, but a hard reset fixed them. Now, I want to roll back to Windows Phone 8.1, but when I plug my phone into my computer via USB cable and try to run Windows Phone Recovery Tool, it won't recognize my phone. Used the "My device wasn't recognized button." Did not help. Opening the file explorer, and my phone doesn't show that it's connected to my computer... Suggestions? Help!

Have you tried a different USB port. Most of the time that happens on USB 3.0 ports and works fine on USB 2.0 ports. Most new devices have few of both

Having the same issue, have tried using a different USB port and nothing seems to be working

Do a soft reset, after you feel the vibrate then click discover my device. That's how I did mine, but mine was in a boot loop so I had to time it right for it to be recognized. I have an Icon also.

I face this before, try search for Nokia recovery tool for retail...this tool is different to the Lumia recovery tool
