Enable USB Debugger on a phone with a broken screen I have done my research on how to enable the debugger, but most of them seem to be useless or missleading. 

Now I do not need any backup, my phone is empty and I use that broken Samsung s6 for testing my apps etc.

I had USB Debugger on but I thought I will reset the phone and I did the factory reset (stupid me) and I assume USB debugger got disabled as I can not access my phone, nor Vysor is working for me.

Simple question, is it even possible to ENABLE debugger on a phone with a broken screen (cant controll or do anything with the phone)?

If the answer is yes, please provide any proper tutorials of how to use shell.
I don't think this will help, but anyway. If you could somehow execute following command on the phone, you should be able to just make it work:

setprop persist.service.adb.enable 1

This will enable USB debugging on the device and persist across reboots. The phone might need to be rooted.

Maybe connect a wireless keyboard and do some key combinations to reach command input. I have no idea how to do that though.
