It could be a stupid question, sorry in advance. If I try to build and install RK3399 kernel on my rockPi4 v1.4 (https://github.com/rockchip-linux/kernel/tree/stable-4.4-rk3399-linux) , what could happen?
a) by sure it does not reboot
b) it depends if you correctly setup all the drivers
c) it could reboot but some functionalities (e.g. WiFi) will be lost because have been customised by Radxa?
In case o c) answer which are these functionalities?
