I'm trying to get KonstaT's Raspberry Vanilla AOSP 13 or Lineage OS 20 working with my Pi4 and my CM4. I chose that version because the CM4 is well supported as he has the device and debugs his versions based around it as well as the Pi 4B. He is not interested in creating a version with telephony framework and I have been trying to research where to begin if I want to re-compile one of his versions of Android 13 with the framework included. I know that I will need the RIL Drivers for my device, which I am working on now, but am having trouble figuring out what is needed to include the telephony framework or where to start. Any advice would be very helpful!
