You can use this source if u Want or Download Builded Kernel / Release build from this https://telegra.ph/Projekt-Walker-419-Kernel-Download-Links-09-25 ,

Clone with --recursive option coz this source has submodule.

Just Copy, Paste, Then Execute the command :)

This Kernel is using Stock Freq. If u want Overclocked Freq, Do this:

To Overclock CPU:

• Add overclock.cpu=1 into boot cmdline. Or
• Hardcode, set this to 1 https://github.com/RyuujiX/android_kernel_asus_sdm660-4.19/blob/test/drivers/clk/qcom/clk-cpu-osm-660.c#L263

To Overclock GPU:

• Add overclock.gpu=1 into boot cmdline. Or
• Hardcode, set this to 1 https://github.com/RyuujiX/android_kernel_asus_sdm660-4.19/blob/test/drivers/gpu/msm/adreno.c#L31

KernelSU is implemented and enabled by default. If u don't want it, Do this:

• Add kernelsu.enabled=0 into boot cmdline, or
• Disable CONFIG_KSU

If u only want to enable Safe Mode (U should enable KernelSU too), Which u just want Root Access and Modules Feature disabled, Do this:

• Add kernelsu.safemode=1 into boot cmdline. Or
• Set CONFIG_KSU_SAFE_MODE=y in defconfig.

This source is still using original driver from 4.4 source... but, i have updated nvt driver.

Working smoothly on mine with new driver.

If u want to use new driver, do this:

• Add use_new_nvtouch=1 into boot cmdline. Or
• Hardcode, set this to 1 https://github.com/RyuujiX/android_kernel_asus_sdm660-4.19/blob/test/init/main.c#L147
• Or, Disable Original NVT Driver in defconfig. CONFIG_TOUCHSCREEN_NT36xxx_ASUS is New NVT Driver.

Pick Spectrum Script from Here: https://github.com/RyuujiX/spectrum , then rename it to init.spectrum.rc

Name: 4.19-xxxxxxxxx

Note: 4.19-xxxx-oc is for Overclocked Both CPU and GPU.

Or , make it by ur self .
