The decoder is blocked

hi

I'm new to your forum, and I need some help from you. I have a Dreambox 920 decoder, I did a wrong maneuver, the decoder jest blokowany, I would like you to help me unblock it. I have to say that I can't solve this problem. I use it most days to watch Tivusat channels with the gold card cam. Hoping to find help, he thanked you in advance.

Ciao, purtroppo non so come procedere. Ho bisogno del vostro aiuto per il mio dreambox 920 UHD in quanto e bloccato. Prima del blocco era montato Dream-Elite. Che devo fare?
