Dumped 64 blocks (1024 bytes) to file dumpdata.bin
proxmark3>

Thirdly I convert them to .eml

script run dumptoemul.lua
--- Executing: dumptoemul.lua, args ''
Wrote an emulator-dump to the file Exxx32A.eml

-----Finished

then went to load the file on to the new blank fob and ran into this issue...

proxmark3> hf mf cload Exxx32A
#db# halt error. response len: 1
Chinese magic backdoor commands (GEN 1a) detected
Loading magic mifare 1K
#db# halt error. response len: 1
proxmark3>

Any suggestions where i went wrong?

Re: hf mf Cload issue?

could the issue be that block 63 is FFFFFFFFFFFF for both key A and B?

Re: hf mf Cload issue?

you should search the forum for the "halt error"..  its known thing.
it shouldn't exist in the latest source from github, so I'm guessing you are running an older firmware/client setup.
Nethertheless,  the clone should be ok anyway.  well,  it depends on how old firmware you are running.
but try reading the clone with  hf mf cgetsc  and the data should be there.

Re: hf mf Cload issue?

The hf 14a in output says no Chinese magic backdoor detected, so I don't think the cload command works with that card.

What gen card is that?
