RE: pySim-shell issues with CHV2 verification (amarisoft sim card)

Good afternoon, Thanks a lot you for your answer. I did the test with the PUK code. but it did not work as well (see log below). The Amarisoft SIM card has two PIN codes, I have the following informations on it : - PIN :  1234 - PIN2 : 1234 - PUK : 12345678 - PUK2 : 12345678 I also think that we have the following commands relative to the (PIN) authentication : - change_chv : edit one of the pin codes (specified with the option --pin-nr) - enable_chv / disable_chv : enable/disable the need to enter the PIN to access files restricted by it - unblock_chv :  unblock a wrong PIN code entered more than 3 times with the corresponding PUK code - verify_chv : authenticate the user with the PIN code (specified with the option --pin-nr) I did try to unlock the PIN2 but it did not change anything (get a similar error). Plus if I enter a wrong PIN1 code, the error is not the same and is really clear. pySIM-shell (00:MF)> verify_chv --pin-nr 1 1234 CHV verification successful pySIM-shell (00:MF)> verify_chv --pin-nr 1 1233 EXCEPTION of type 'RuntimeError' occurred with message: Failed to verify chv_no 0x01 with code 0x31323333FFFFFFFF, 2 tries left.

Here, you get an error indicated by the SW code 6B 00, which means "wrong parameters P1 or P2". This can correspond to the length of the PIN 2 expected to be longer than the one you provide.
