4byte 4K fob, hardnested error

Hi. last time I got 4byte 1K fob, no chinese magic command, hardnested one.

Key a of sector 15 was not found, so tried

-hf mf nested 1 * s

with this, key found, then dumped data.

This time, fob is same, 4byte 4K fob, no chinese magic command, hardnested.

key A of sector 7, 15 was not found. Key B all good. (ffffffffffff) with -hf mf chk *4 ? d (or default_keys.dic)

tried -hf mf nested 4 * s (or ss)

-Tag isn't vulerable to nested attack...
-Auth2 error

So tried hardnest

-hf mf hardnested 0 a ffffffffffff 4 a w s

at first it looks working well, then

-AcquireNounces : Can't Select Card UID ... continuously

with

-hf mf hardnested r

works well, no result. sad

so how can I get two more keys A of sector 7/15? any problem with command?

Thanks.

Windows 7 and latest official version of pm3 (and pm3 Easy)
With iceman version, hf mf chk *4 ? d not worked (all empty)

New Client - old firmware?

And keep a small distance between card and antenna.

Re: 4byte 4K fob, hardnested error

Thanks piwi, but it is same version, latest 2019/8/11 official version, firmware/client.

Today I ran it, hw tune... then hardnested, no more errors.

But, finally it showed nan : nand (after 3 hrs job smile

there was no key, no result, onlt nan : nand then finished hardnested.

Tried -hardnested r option, 6 hrs, then same result, nan : nand.

nothing changed, same condition, same result.

All key A/B ffffffffffff, only sector 7 and sector 15, not found (????? or 0)

do you have any idea?

Or I checked other posts, similar conditions happened, how about current fork of official and iceman, is there any problem with hf reading?
