Essential, the tech startup by Android co-founder Andy Rubin, released its first phone back in August. There has been exactly zero ROM development for the PH-1, but part of that is because Essential had yet to release the phone’s kernel source code. Just over a month since it started shipping to customers, the PH-1’s kernel source is now available to download.
If you’re unfamiliar with this process, Android’s Linux kernel (the very heart of the OS) falls under the General Public License v2, which requires that any modifications made to the kernel have to be released publicly for anyone to use.
