Bootloop after root

As topic says, I ****ed up the root and now im in a bootloop, I can get into the download screen, however.. I cannot get into the recovery screen where you can reset the phone.. I've tried 4 different firmwares and none of them works with odin. I live in Sweden and has Telia as a carrier if it matters. Please help me. I'm kind of panicing right now since this phone cost me over 00

I have the "SM-G920F" And was using Android 5.1.1 Lollipop.
