This could be implemented in a combination of shell scripts and possibly integrating some C++ or Java components, depending on the crdroid's architecture. Utilizing Android's official tools and libraries (like fastboot, adb, and AOSP source code snippets) could streamline development.
fastboot flash boot_a crdroid_boot.img
fastboot flash boot_b crdroid_boot.img
Or use:
fastboot set_active other
fastboot flash boot crdroid_boot.img
crDroid boots with SELinux in Permissive mode on some devices. To check: Terminal → getenforce. To enforce: crdroid bootimg install
Many crDroid builds require disabling verification. Run: This could be implemented in a combination of
fastboot flash vbmeta vbmeta.img
fastboot flash vbmeta_system vbmeta_system.img # if present
Flashing the boot image is only the first step. The full crDroid experience requires additional components. Or use: fastboot set_active other fastboot flash boot
Purpose: The feature "crdroid bootimg install" would allow users to easily install or flash a custom boot image (boot.img) specific to crdroid ROMs directly from a recovery mode or a fastboot mode without needing to use more complex tools or manually navigate through file systems.
