update:
so I want to try to see if I can apply the overclock in android, but I have very little experience in how to do so, I presume coming from the linux standpoint it can be done with dtb/dtbo modifications but I’m not very sure about how I can do that,
any help from android developers here is much appreciated, thanks!
