Re: #db# Authentication failed. Card timeout.?

Yes Kra seems it's bug,

I try to mifare 1k from same system same time edition, when run 'hf mf mifare' for one card it returns valid key, for another invalid key, then I run 'hf mf mifare nt' I return another invalid key, so I can do it more than 10 times but every time it return invalid key with different nt, then run 'hf mf nested any key' it return ' #db# Authentication failed. Card timeout.' Seems something wrong with rev #498, becouse I know 100% that is old mifare 1k card. Have You tried ratte bug fix? Is it work? Maybe it's for unclean or suspect how it should I don't know too:) anyone?
