Help, idea are welcome :-)
Always on research, it seems that some blocks are paired with other with countdown. Now my tag are not detected any more, since i can't change back block 05.
]]>I continue my investigation on my tag, with some brick .. (4)
On the datasheet i can see that the SRIX4K ST got anti collision and anti clone.
On my test, i try this
- TAG 1 Value block, use it on machine, after put previous value block (several block change), i try to put them all back and one by one.. 'except block 05' because brick tag
when i do that, tag no works anymore.
- TAG 2 put value block of TAG 1, works one time, but never success to make it works again...
The command
hf 14b info give me chip bit protection raw: 11111111
14443-3b ST tag found:
UID: d0 02 0c .. .. .. .. ..
MFG: 02, ST Microelectronics SA France
Chip: 03, SRIX4K
Chip Write Protection Bits:
raw: 11111111
07/08: not locked
09: not locked
10: not locked
11: not locked
12: not locked
13: not locked
14: not locked
15: not locked
can i use raw 11111111 key to make write enable on block 05 ?
Because i can't change block 05, or one time, after block is unwritable again, or i can send only 00000000.
Any idea ?
Thanks !!!!

hf 14b srix4kread
New test today, with 2 other Tags
First one with 0.02 euros on it and second with 0.14 euros on it.
I can't see where euros are stocked, any idea ? 02 & 0E ?
hf 14b srix4kread is good for reading tag ? or must use raw ?
]]>if i send hf 14b sriwrite 02 05 fffffb0f
got
[SRIX4K] Write block 05 [ ff ff fb 0f ]
received 0 octets
but no write
the block 05 stay on last value
so strange.. need to change firmware ? I don't have the problem on other block 00 to 7F
]]>A full copy of the tag will be more usefull to play, because
Sending reversed hex manually is long !
Thanks
