Updating simlock error

I was wondering if anyone knows a Android RIL implementation (and platform) that does use something other than CRSM (like CSIM, or some other type of raw SIM access).AT CSIM Command: This one is the eldest and most well-known command: some phones allow you to use one of the standard-defined-but-not-always-implemented AT command AT CSIM which let’s you to send raw APDUs (=”commands”) to the SIM-card via the modem.We can't use STK because we can't install Java Card applets onto SIM without a key, which only the operator of the SIM has.You can only install an applet if you have a developer SIM where you know the key or if you have somehow the luck to get a SIM where you don't need the key.ME error result code CME ERROR may be returned when the command cannot be passed to the SIM, but failure in the execution of the command in the SIM is reported in and parameters.Coordination of command requests to SIM and the ones issued by GSM application inside the ME is implementation dependent.It’s not returned after a successful UPDATE BINARY or UPDATE RECORD command. However commands READ BINARY and READ RECORD can be issued before PIN authentication and if the SIM is blocked (after three failed PIN authentication attempts) to access the contents of the Elementary Files.

There may be many ways to read the file system on a SIM card.This should read Kc from file 0x6F20, doesn't work on my SIM By using this command instead of Generic SIM Access CSIM TE application has easier but more limited access to the SIM database.Set command transmits to the ME the SIM and its required parameters.
