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?
Below is my failed session with a SIM, trying to create FID 0xabcd under 3f00/7f20. Any guidance is greatly appreciated.

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?

It looks like 0x98 0x04 is 'access condition not fulfilled' or 'authentication failed'. Regardless it appears I am not verifying proper access conditions.
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?
Yes it is present. Although the card does not contain a file in this directory that I need. I'm trying to create a file underneath the DFgsm directory. I assume I need to select the directory in which I want prior to invoking the Create File APDU.
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?
