Can I Flash HD 6 Via PC. TWRP Manager and FireFlash Load to Black Screens

I need to reflash my HD 6, it is rooted, but I can not load TWRP Manager or FireFlash, they are granted Root permission, but only load to black screens.

How can I flash a file such as twrp_ready_update-kindle-20.4.5.4_user_454006120.zip using my PC instead of an Android app?
