Kirin Kernel Source Code

Huawei has released the kernel source code for Kirin 980 and Kirin 970. I dont understand why there are no roms for this phone. https://www.xda-developers.com/huawei-kernel-source-code-kirin-980-kirin-970-android-pie/
Just a thought; wouldn't one need an unlocked bootloader to install a custom recovery, and then flash a custom ROM?
Since Huawei has gone to some length to hinder owners of this device to unlock the bootloader, the developers might feel reluctance to develop for it?

Please help me root vivo v9 android 9

how to root vivo v9 android system 9 (PIE) user from indonesia. thanks
Vivo not only lock the bootloader but also add the verify to most of the partitions.So even if you unlocked the bootloader,you can only flash the official firmware and cannot do any modification.
So it's impossible to root this device.I suggest you to change another device.
