Bricked G950F after Magisk update

[dayiahmet_23]

Hello guys, I have SM-G950F and the device won't turn on. After flashing the software with Odin, it enters the recovery mode. When I try to restart the device it says "Samsung Galaxy S8" and keeps restarting by itself. When I try to flash TWRP or something different (except the stock rom), it gives a warning like "Only Official Binaries Allowed". In the link I left below, there are two short videos and two pictures about the status of the device.

Kg state is prenormal. Is your bootloader unlocked? Did you release Vaultkeeper.
