I don't know why people still need custom rom for this. The manufacturer rom already very good and stable

The reason why people change roms is to get rid of the bloatware and sometimes it has a performance boost and battery life is much better. Also a lot of features that you normally can't get.

without knowing exactly what you did to your device Cannot help...
But for now I will suggest flash stock (dvl1) with odin & flash zip again.
Before flashing zip take a backup to quickly recover the device.
