Hi @Members_P5rj3lg
On official security update / software update via your phones software update section wouldn't clear the phones imei.
I would suggest to reach out to a Samsung Service Centre for support.
Daily Driver > Samsung Galaxy s²⁴ Ultra 512Gb ~ Titanium Black.
The advice I offer is my own and does not represent Samsung’s position.
I'm here to help. " This is the way. "
