Samsung note 4 in deep shyt

Hey guys, Im having some issues with my samsung note 4 SM-N910G 5.1.1 lollipop. Yesterday I tried to flash the stock rom which I downloaded from sammobile, but it didn't work as it took forever. Now the problems Im encountering is that the phone can't enter recovery mode by pressing vol up+home+power. Instead, it shows a similar downloading screen as when vol+down, but the top message shows "unable to boot" or something. Now Im trying to flash the stock firmware, but it takes forever and doesn't seem to move, as follows:
Ok, it just failed flashing:

When I boot it up normally by pressing power button, it goes into a bootloop.
Hope to receive some help here.

Thanks.
