Soft-bricked AWID Card

I was experimenting with a Zipcar Zipcard, which uses the AWID ecosystem. While attempting to clone the original card, I mistakenly left the original in the antenna field while executing a t55xd write operation.

After that, the card is no longer found with lf search or lf awid fskdemod as did previously.

I attempted to repeat a full t55xx write in hopes it was a t55xx based card, which works when cloning the original card value, but I've been unable to get the card to respond to any commands. The AWID reader field detects the card, but does not read any valid data from it. When I run a plain lf read, structured data is returned, but not in any recognizable bit format.

Any ideas as to what might have gone wrong here?

Re: Soft-bricked AWID Card

you most likely wrote over your zipcard,   

try first verify that your zipcard is t55xx based,   by writing a known to work block 0 configuration.  Then try the "lf t55 detect".
if that was the case,  you can now write back your old tag data (from your clone posts)

if not,  then it could be a matter of the zipcard is pwd protected.  good luck with that,  try default values like all zero's or ones.

If not it can be a different sort of LF tag.  You need to identify it.
run :   data plot,   lf read,  data sample.    and share here what the signal look like and the output of the commands.
