Install wprt on your pc.. Open the app.. Connect your phone via usb.. Wprt will detect your phone.. Click on the phone icon.. download the software(which will be cyan).. Install..
Note: You can unplug your phone while downloading.. but do not unplug your phone while installing software.. After downgrading install denim through phone update

Moved to Windows 10 Mobile forum, since this topic is about phones, not PCs.
