I know its been talked about in length and I've read about every thread available all over the internet about this. My phone came with lollipop and I've read that on kit kat, sim unlock was possible. So here are my questions......Is the sim unlock in the modem, kernel, system, bootloader or somewhere else? What allowed the "unlock code" to prompt in kit kat? The dialer codes are in the phone.apk correct? What if I flash just the 2 modem files and swap the phone.apk back to kit kat. Is there a chance that would work?
