Flipper unable to unlock locked MIFARE Ultralight C

NFC
#1

Hello everyone. I recently got a hotel card and tried unlocking it with the MIFARE Classic Dictionary, but it kept on saying, “

Sectors read: 0/5
Keys read: 0/10

.” I also tried unlocking it with the reader, but it doesn’t even detect the reader. Does anyone know how to fix this and unlock my card?

So… Is your card Mifare classic or Mifare ultralight C? Your post is confusing. What have you tried to do? Like, step-by-step
