Try
hf ic dump --ki 1
hf ic dump --ki 2
maybe it’s using one of the other keys that the pm3 has built in (if we’re lucky)
iirc the “failed to communicate with card” error is coming from a failed authentication due to wrong key.
also…the directory on your dictionary files looks a bit odd.
\dictionaries/iclass_default_keys.dic
vs
\dictionaries\iclass_default_keys.dic
that may also give you different results.
let us know what you find!
