Received my PM3 RDV4.01 and destroyed many cards...

Dear Everyone,

I am just trying to get my head around after destroying many iclass cards (assuming write the wrong information on block 3).

I have been with the forum for over two months. Bit by bit, I learnt a lot from you guys. It is really time consuming but definitely fun!!!

Specially thanks to Iceman, Carl55, holiman, 0xFFFF, marshmellow etc. Great work!!!

During these months, I purchased wrong readers, correct reader, Chinese cheap pm3, genuine pm3 RDV4, wrong cards, correct cards.....my wife said I am crazy...

I admit that I am still an amateur - The command which has killed a lot card is calcnewkey after I got Sim 2 work and got the Kcus from iclass elite reader.

I am trying to write data on iclass standard security card (in order to convert it to iclass elite card, is it possible?).

So what exactly the old key and new key means in the "calcnewkey" command?

I have tried:

1. old key as the data on block 3 on the legacy card, new key as the data on block 3 on the elite card (to be copied)
2. old key as the standard master authentication key, new key as the elite custom authentication key (Kcus, standard format)
3. old key as the standard master authentication key (permuted), new key as the elite custom authentication key (Kcus, iclass format)
4. old key as the data on block 3 on the legacy card,  new key as the elite custom authentication key (Kcus, standard format)
5. and etc......

Then I got different sets of the following:

[+] Old div key : 1111
[+] New div key : 2222
[+] Xor div key : 3333

I wrote hf iclass writeblk b 03 d "Xor div key" k "permuted standard master authentication key"
in order to convert this standard security iclass to elite one (of course, I have clone the rest blocks 6-12 in addition to this).

However, after tried so many times, and after reading all the relevant posts, I did not get the good result.

Any comments, please.
