have a lg g2 that is blacklisted if unlocking emei code work

You can't legally change the IMEI code on your device. If it is blacklisted, you will not be able to use it on any carrier.

Your phone is now good only for parts, or you can buy a motherboard with a good IMEI and install in in your phone (which won't cost much less than a new phone, and more than a good used one).
