Hey, do you have a telegram account for easier conversing? I feel we might be able to help each other here(I'm working on sofiar)
I can make one and ill dm you.
Here are my questions so far / some observations.
The init.rc that the twrp build system puts in the build is incorrect. It needs to be manually added...I think there is a flag for that actually, but I had to change it once it was built. (I was able to make it boot to the first screen by dropping in things in /sbin from
https://github.com/TeamWin/android_device_motorola_chef)
The build system doesn't add the twrpres folder to the built image lol; or the twrp binaries to /sbin.
I literally had to copy them over from chef.
Also for example servicemanager and hardwaremanager aren't in the chef repo but they are in /sbin when you unpack the recovery image (chef), is the build system building them or putting them in from somewhere or are the repos not actually the final product and they had to hack the image a bit too.
I had ours added in then took it out when I couldnt find them in anyones device tree but they are there when you unpack all of the recovery images lol.
edit: It's actually putting most of the stuff (adbd) and symlinks in /system/bin including the recovery bin which is twrp, so let me readjust the init scripts.
our device is different it still has /system and not system_root.
another edit: Looking at android_bootable_recovery/crypto/ex4crypt I think im missing some libraries still.
