Samsung A8 KG State prenormal

I have problem with KG State prenormal on my Samsung Galaxy A8. So, I installed TWRP, after I installed SaboorROM, and after connect to WiFi, the device set's the KG state to Prenormal and I was unable to boot into TWRP or into SaboorROM. So I installed Stock ROM (AP: A530FXXSBCTC4 | CSC: A530FODXBCTC2). After install I enabled Developer settings and OEM was already unlocked. So I tried to "date|time changing experiments" to reach KG state checking, but nothing worked. Than I was about 500 hours if KG state will change, nothing :/ OEM: unlocked FRP: unlock KG: prenormal Binary: 11 Android: Pie **How to change KG state?**
