Hi @mifaresdk,
I thank you for all the support you provided for me.
The dump tool for the MIFARE Classic has an option so I can enter my new read and write key.
But I guess I made some mistake while inserting new key so even dump tool also can’t read the sectors trailer.
If I don't change the sector trailer keys then I can write my data and read back as I expected.
The default key registered in 0x00 contactless card controller and the new key registered in 0x01.
Something here is not right. So I will forward my questions to my contactless card controller SDK team and seek their answers.
Kind Regards
