Hi @Tilico, welcome to our forum!
Your question has been translated to English as this is an International forum.
I'm not quite sure that I understand your question even after translating it, what kind of blacklist are you talking about? If the device has been blocked by your operator due to it being reported stolen or something similar, please get in touch with them.
I hope that helps and if I misunderstood your question, please do elaborate.
