Flipper Zero can read cards but can't emulate them

[FourK]

Hello everyone,
I just my flipper zero yesterday, and I am testing my flipper today. My flipper can read the card correctly, finding 32/32 keys and 16/16 sectors. But when I try to emulate, through the flipper, to the reader to open the lock, the reader does not pick up the emulation. I know the lock can be opened with a flipper because my friend’s flipper can read the card and emulate it, and the door will open when they hold it to the lock. My flipper is fully updated, so i know it is not a software issue. If someone could help me if me determine if flipper is defective, I would really appreciate it.

Hey FourK,

Were you able to solve this issue? I just received my FZ and have read a couple of RFID cards successfully (yet to test), plus our apartment door lock NFC app which I run on my Android phone to open our apartment door. The NFC app was found to be an ISO14443-4A (Unknown) card. When I emulate it, I can only emulate the UID, not the entire reading. Door won’t open, upon emulating the UID.

Anything more that I can do to try and get the NFC app duplicated successfully?

TIA!

I had the exact same issue. I’ve tried a bunch of different firmwares, not only because of this issue but to find out what other features are out there. Yesterday I switched back to stock Flipper firmware, wiped the sdcard and after that I can emulate all kinds of cards.

I think it’s the same that the bug I report a few days :

Bug in MIFARE Classic 1K emulation

Hello, I would like to report a bug that I have since the 0.94 firmware version : It’s not possible anymore to emulate Mifare Classic cards (copy of VIGIK systems). It was working fine in 0.93 (so i’m stuck in this version and can’t update) but not since the 0.94 firmware. I try to understand why and use a ACR122U reader. With version > 0.93 : If I I write the file emulated on an empty magic card, the card will work perfectly and I can read it on my ACR122U with all sectors and no errors. I…

Hope it’l’ help, NFC emulation is broken since version 0.94.
Try to use 0.93, it’s emulating the whole card with it.

I got it working with 0.96.1.

What do you mean by working? You have checked that Flipper emulate the full card with all sectors ?

I have not done very much testing but it seems to fully emulate a handful of cards that I briefly scanned, emulated and compared using my android phone.
I also now can use the Flipper to unlock the door to my house.
