Hi, straight to the point. I am having a problem with coping with my card(Mifare Classic 4k) I want to copy my card then later repaste. I have tried it with my friend phone, with an app called Mifare classic tool it worked fine. I could copy the dump info and write it again.
I have the key for it.
I have tried with other tags like 1k
(I don’t want to change the UID, just the data)
And yes, everything is connected right, i tried dumbinfo.ino it worked fine. But I can’t put my key in so it just comes up as failed. But I’ve tried with other codes it worked fine.
And this is what i get, i try to scan the card but nothing comes up
Try the most used default keys to print block 0 to 63 of a MIFARE PICC. 1.Read card 2.Write to card 3.Copy the data. Read the card Insert card...
appreciate any help
