Re: hardnested: response just "#db# AcquireNonces: Auth1 error " Why?

There seem to be more problems with communicating with the card.

[!] error:  selecting tag failed,  can't detect prng
Prng detection: HARDEND (hardnested)  

Which device do you have?
Whats your output for  HW TUNE?

proxmark3 easy

pm3 --> hw tune

[+] measuring antenna characteristics, please wait........

Fun fact:
After my cat took her place on my desk, hardnested went through:
