Undo secure at Mifare chip

[valentinvogl]

Hi,

I accidentially secured a Mifare NFC-Tag with NXP TagWrite.

But not just the write protection.

I activated the permanent protection.

Is there a way, to delete the chip?

I can't do anything except reading it.

Formating is also not possible.

I also can't undo the protection.

There is always a error message with chip is partially secured.

Thanks :smileyhappy:

Hello Valentin Vogl:

I think since it is a "permanent protection" the security will be irreversible.

But just to confirm, could you let me know what type of MIFARE tag you are talking about?

Regards!
