It is for making unlock patch. You need another tool to apply the patch to your phone(jdflasher in this case). But first you need to run the "executor" (bypass the CID protection), and then jdflasher will be able to modify the MAIN according to unlock patch(unlocking the phone).Your telling me the purpose of this "remove sim-lock" patch generator isn't to unlock the phone so you can use any sim card?
So, temporarily you need to use the "correct SIM card" to be able to run the executor.
