it's possible to kill T5577 ?

After a few I think I killed two cards of type T5577, I think I have typed a bad id during tests of clones ... (I did not understand the mode stand alone), I tried to rewrite the block 0 with a new id, but I no longer communicate with these cards. Do you think I little throw the cards?

my last writing is :

lf t55xx write 0 03C294CB
Writing to block: 0  data  : 0x03C294CB         
Error occurred, device did not ACK write operation. (May be due to old firmware)

Re: it's possible to kill T5577 ?

the purpose of t55x7 cards is to simulate different LF cards. Its fully possible to emul a em410x.   The clone commands is targeted to t55x7 cards.  Don't write to block 0, if you don't know what you are doing.  Block 0 is the configuration block, which decides how the t55x7 should simulate.  Writing a bad configblock (bad values),  you can brick it, like in perma-brick it.

I suggest you read up on this forum, and wiki for LF commands and datasheets.

you probably brick your card. try using lf t55 wipe. if it doesn't work, then that tag is perma-brick.

Maybe you could tell us what you want to do with it so we could better help you ?

Re: it's possible to kill T5577 ?

You first have to program the radio block back to a setting that will work for your programmer.  Then you can have access to the data registers again.  Sometimes particular programmers can't set this block (block 0) back to usable settings, which can make the card inoperable.

Re: it's possible to kill T5577 ?

try to reset t55 card first with :

lf t55 wr b 0 d 00148040 p 00000000

then do your new block 0 configuration :

lf t55xx write 0 03C294CB

...

Let me know how that turns out !

That looks like a strange config block.

Re: it's possible to kill T5577 ?

well am not sure how strange it is(03C294CB), but am sure it is the same config block in the previous post  /viewtopic.php?id=4603

Re: it's possible to kill T5577 ?

that link goes to a very old thread,  but not posts about that configblock...
