Writing on sector 0 block 1, 2, and 3 (sector trail)
Hello,
I know sector 0 block 0 can't be written other than on a magic card (UUID...).
What about sec0 block 1, 2 and 3 on a normal mifare classic 1k ?
I get the error when trying to write, read is ok :
#db# Cmd Error: 04
#db# Write block error
#db# WRITE BLOCK FINISHED
So the auth is OK but the access bits is set so I can't write with the current key.
I tried the other valid keys I have for this tag.
Is there a way to find the hidden key that has write permissions for sec0 block1/2/3 ?
Or it is like sec0block0, just impossible.
Thanks,

read about the sector trailer. It has besides two keys also access rights.
