It looks like 0x98 0x04 is 'access condition not fulfilled' or
'authentication failed'. Regardless it appears I am not verifying
proper access conditions.
Hello,
I'm struggling to get the 'CREATE FILE' APDU to work on a GRCard SIM.
I'm
using the cyberflex-shell in interactive mode to send apdu's. Even though I
verify ADM pin 5, and follow the format on the wiki (
http://openbsc.osmocom.org/trac/wiki/GrcardSIM), I still get the reponse
0x9804 from the cards. I must be missing a step?
0x98 0x04 means "in contradiction with CHV status" (3GPP TS 51.011)
Below is my failed session with a SIM, trying to create FID 0xabcd under
3f00/7f20. Any guidance is greatly appreciated.
7f20 is the reserved id for DFgsm.
Is this file (directory) not already present on the card?
the card tells you 17 bytes of response are waiting
for you.
this is the select file response, and will tell about the status of the file you
selected, and the corresponding access conditions.
did you verify them?
This is the SELECT response on DFgsm (0x7f20). Upon decoding, it
appears there are a total of 12 CHV's and codes. I've tried resetting
PIN1, PIN2, ADM1, and ADM2 all successfully, then verifying all 4
after selecting the DFgsm file, but I still get response 0x9804 when I
try to create a new file. Create File on these GRCards use a
proprietary APDU which I followed from the wiki, Not sure what I'm
doing wrong?
SELECT 0x7f20
