How do I make a custom kernel?

Booting The Compiled Kernel:

  1. Browse to /out/arch/arm64/boot and find the Image-dtb file (compiled zImage) and copy the file.
  2. Download Android Image Kitchen and decompile your stock boot image. Once you decompile it you’ll find the stock zImage in the decompiled folder.
  3. Flash via fastboot using the following command:

Where to find the version of a Linux kernel source tree?

I have downloaded from a hardware vendor just a tarball of their Linux source tree (no Git repository metadata), is there a way to find out the version number of the kernel? Is the version number usually stored in a file somewhere in the source tree? I’d like to be able to do this without compiling and running the kernel.

Which is the best way to get Linux source?

apt-get source linux is the easiest way. It will download the source from your repository – and it’ll be the same as the version you’re running (assuming you haven’t already customised it). But if you want to find where the source is maintained you can run:
