I have a mifare classic 4k card (that is used like a 1k card, I successfully copied first few blocks to a 1k card and it works) and emulation works fine.
But we have an update terminal that should regularly be used to update the tag. If I hold the flipper in emulation mode in front of the reader/writer it makes a weird confirmation noise that’s different from what it makes when I use the original/cloned tag, and while there is a shadow file created on the flipper it does not contain the expected new data.
Does anybody know what the problem is? Am I doing something that’s not supported?
