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?
[...] Sadly there is no workaround just yet. 1 week no reboot is useless if you are on Bootloader 7 (Android 10 or latest android 9 update)
