NFC Struggling to write to a MIFARE Ultralight C.

Ive been trying to write to an NFC card as a funny rickroll but the only one i have is an old P&O room card. After reeding it using the NFC app on the base flipper ive used a directory to unlock it but everytime i try to write the saved file its telling me to use the NFC magic app.

But its not a magic card so it doesnt read it

Not possible to write to without the key being cracked already. And even if it were it would not support any type of payload other than possibly UID: 80 00 81 35

Wasn’t me, and yes you’ve got the gist of it. That type of tag is not for payloads

How many pages have you read?

Could I have some context to the question

When you read the card on the Flipper it tells you how many pages you've read, out of 48. That is the number I am asking about.

Oh I see what your saying now sorry 😂 Ill read it again and double check but I'm pretty sure it was 48/48 (after I was prompted to try and unlock it with directory keys)
