Blackberry Blend and Blackberry OS 10 are discontinued. Blackberry lives on as premium Android-based devices.
Blackberry Blend requires a Blackberry OS 10 device to be the main/central device. You CANNOT use Blackberry Android hardware as the ‘main’ device, only as a viewport to the BB10 device.
Blackberry Blend on a Linux PC was best run in a virtual machine. Blackberry Blend works from Windows 10 using wireless (WLAN, 3G/4G) connection to the Blackberry OS 10 main device.
