I am attempting to patch firmware from the Korean EV6 to the NAM EV6 (to have wireless CarPlay in their latest update). I have been able to decrypt the tar list and edit, then encrypt again. But I believe inside system_package there is an update_info file that is encrypted that is causing issues. The moment I change the system images the headunit will not install. I have been updating the 2022_EV6_USA.ver file with the updated CRC and file size and still will not install. Any ideas?
