Possible error codes:
UPA<CR> Unknown parameter
NMA<CR> No MiFare 1k or 4k chip authenticated
BAE<CR> An unauthenticated block is chosen
BNA<CR> Block not authenticated, Block No. is not in authenticated sector
TNR<CR> Tag not responding (Tag is no longer in read range)
EDX<CR> A decimal parameter cannot be interpreted as a decimal value
5.3. Sector Trailer Manipulation (STM)
This function simplifies the usage of the MiFare classic access conditions and key writing.
With this command you can change the access bits and don't have to write to the trailer
blocks directly which should reduce errors resulting in destroyed transponders. As described
in the Appendix, the sector trailer contains information about keys, block-mode and
Access-Modes. Use this command to set these access bits and/or keys.
