FKM Custom Kernel Documentation

Franco Kernel Manager supports adding custom kernels to the automatic flasher. Any kernel developer can easily create a config, and users can then import the config into the app for fast and convenient kernel updates without having to manually flash anything. Update notifications are not currently supported, though support may be added in the future.

JSON Configurations

Custom kernels are defined using JSON configurations. Here is a sample configuration for a hypothetical Zen Kernel that supports the Pixel 2 series:
