OpenKirin is a project to bring stock Android ROMs as well as other ROMs such as the LineageOS, Resurrection Remix OS, and CarbonOS into the Huawei and Honor ecosystem. As for now, the project currently supports 17 phones and tablets that are running the EMUI 8, notably the Huawei Mate 10, Huawei Mate 10 Pro and the Honor View 10. Unfortunately the project only lasts until 22 July 2018 so be quick if you’re interested in flashing your EMUI devices. You can check out the complete list of supported devices and downloadable ROMs on the OpenKirin website as well as guides to install the custom ROMs as well.
Needless to say but since this is not officially supported by Huawei or Google it invalidates your warranty and there is no guarantee you'll get updates as fast as say a Google device or even an EMUi supported device. So be aware. For more updates like these, stay tuned to TechNave.com.
