How to collect troubleshooting log in Windows Phone

My Windows Phone (Lumia Icon) has recently run into some trouble when I upgrade it from Windows Phone 8.1 to Windows Phone 10 Preview.   It constantly reports the error “0x80070002” and fails the upgrade.

I contacted the Microsoft Support, and the support professional shared a useful troubleshooting tool for Windows Phone called “Field Medic”.
