Goodevening,
I hope that somebody can help me. I use a z12 ultra since the beginning of februari but since yesterday it says this device is block. I factory reset it and it worked again but today again it says device is block. I already made a ticket to formuler but they are not helping and saying that i need to contact my seller. It is not possible to contact the seller because i bought it on vinted and the seller is not on there anymore. The box was sealed and new.
Greetings and a nice evening
Marc
