In your Download mode screen I see
KG status Prenormal.
I think we really need to account for the reason for seeing that.
This can happen when the phone is being used now in a country different from the one it was intended to be used in when Samsung sent it out. Put another way it has been imported in a slightly irregular way.
Could that be the case here? Do you have all the original labels and packaging? Edit, or alternatiely that it has not been used with a local SIM card in the local country for a specified time to “lift” the restriction.
