Read Mifare clasic 2k/4k

Maybe dumb question but…
How to read Mifare classic 2k/4k card with flipper?
I know all the keys but flipper reads 16 sectors and says “Keys Found: 32/32”, “Sectors Read: 16/16”.
I wonder how to say flipper there is more than 1024 bytes in the card?

2k is definitely Mifare Plus card, in your case working in SL1 mode. Flipper can’t detect Mifare Plus cards at this moment, but after ongoing NFC refactor it would be possible (because Plus card size can be only determined via ATS, currently all cards are detected with ATQA/SAK, for Mifare Plus (and a lot of other cards) it always ATQA=00 20).
