GP Verify error: GP init update failed. recv: 6D 00

[jsalazar]

Hi everyone

I currently have 3 programs that I want to write in a blank Sim Card that I bought. However when I verify the GP to install the applet in it and I am getting the next error message:

GP Verify error: GP init update failed. recv: 6D 00

I have the PIN, PUK and IMSI numbers of the Sim card. How can I Fix this issue? Can someone guide me, please?


Thank you in advance.

What's the model of your card?
Is there any document the card provider give you?
The response of the SELECT command looks have any problem.
And please switch to tab "Basic APDU" to show more details to us.

Hi UNKNwYSHSA

Thank you for your response. Here I am attaching the message that you wanted to see in "Basic APDU." Additionally, the sim card model is sysmoSIM-SJS1-4FF and I didn't get any documentation for it. I am a newbie in the JavaCard development and to be honest with you, I still don't understand what is GP and if I need to have a specific GP key for each Sim model and brand? Do you know where to find them? Do you know how to set them up?

Do you want to use GP to establish secure channel and load applet to the card?

Here is the information of this card: http://shop.sysmocom.de/products/sysmousim-sjs1-4ff
And the card manual: https://www.sysmocom.de/manuals/sysmousim-manual.pdf
And you can use this tool to upload applet to this card: http://git.osmocom.org/sim/sim-tools/

Other question(s), please let me know.

Hi UNKNwYSHSA

Thank you for responding my question. Actually, I am interested to establish secure connection channel and load applet with GP because this will help me to understand. Additionally, I believe that this is a good practice for me because I am fairly new programming in JavaCard and I may use other Sim Card brand. I appreciate if you can guide me, please.

I am so sorry for reply you so late.
You can refer to opensource project GPShell and GlobalPlatformPro to research the method to establish Secure Channel.
But for the card you haven, the card manufactor maybe implement it with their private method.
So you have to ask them for your needs.
