Hi mifaresdk,
That is my problem. I read all the that info and get very confuse. I calculated mant time and find many diffrent answer.
And after reading your mail;
1) Access conditions for data block 0
2) Access conditions for data block 1
3) Access conditions for data block 2
4) Access conditions for the sector trailer
For all conditions I have to set "Access Bits" as follows.
1) Use Key A for reading
2) Use Key B for writing
I find that I have to use;
08778F FF (08778FFF)
as a access bits so I can use Key A to read all conditions and I can use Key B to write all conditions. I attached the picture as well.
Am I right or wrong?
Kind Regards,
