Hi, I tried to change the settings, the main error that does not disappear is the service tag. Can you tell me what exactly needs to be changed so that the tag is saved, maybe you need to turn something on/off in the "security" menu?

is there an engineer in this community or are there only sofa experts who repair only by replacing the motherboard with a new one

@User1978​ Will this problem be solved?
