SM-G920t1 unkwnon baseband

ive been trying to fix this phone. at the moment it has no baseband and ofcourse no IMEI I tried to do drk repair and I tried to wipe efs and uart never connects I’m not sure if its cause of the baseband. I already flashed latest software in phone through kies and I still don’t get baseband. I also flashed nv from another phone along with efs and still nothing. has anybody been able to fix unknown baseband? here is the phone info.
