In this video tutorial, I'm going to build the kernel for my Samsung S4 (I9506) codename: ks01lte
PREREQUISITE

☐ 64bit Linux system (you can also install it in vmware or virtualbox)
☐ kernel source of your phone (you can download it from the manufacturer's site)
☐ toolchain (download it from googlesource or build your own from source)
☐ android image kitchen (for repacking kernel)
☐ and some patience

## BUILD ENV
apt install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev \
gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev \
x11proto-core-dev libx11-dev lib32z-dev libgl1-mesa-dev \
libxml2-utils xsltproc unzip bc

@fossfrog can you specify what commands to be used to install the packages @1:03 ? i have downloaded the kernel source zip and the tool chain so far.

[RamlalChoubey]

Pls help whenever I download the google toolchain it is getting downloaded directly in folder and not in tar.gz format pls help

HI, Can you help me modifying nethunter kernel?

[bruv_jz]

Question: do you know how to overclock a kernel like cpu refresh rate etc?

[PandaxOficial]

It is very difficult for me since I am Spanish and I do not understand. I want my Android to be able to be used as HID Attacks. how should i do? please just give me the instructions like Kali net hunter .. I have Installed Kali nethunter but not working for HID Attacks like Rubber Ducky

Is this actually full groans..that seems majestic if it was just hymns

[mouseflex]

Hello thanks for the video i was great for me. i have some cuestion, its posible upgrade a new kernel?

[dxcvvxd]

i have a very important question: can i build a custom kernel without having the sources? (mediatek + china phone moment, they didnt provide the source code)
i know its very risky and all but mtk devices are easily unbrickable so yeah

Hey im new to kernal modding. But just a quick question, in the kernal source>arch directory, if we are building for arm64, do we use the config from the arm or arm64 folder?

edit : use the arm64 config

[imSomebody-mc]

Thanks even if this is old tutorial, I'm trying to build mainline 6.2 kernel for android (it already has mainline kernel but no arm64 kernel for android)

Hello sir, i am planning to overclock a little bit the cpu using kernel modification, but i am still getting stock cpufreq, even bootloop and random crash. How to know the files that i should modify to overclock my cpufreq? I am using msm8953 device with 4.9 kernel

[keshayengames]

Hi Foss Frog, I already have a kernel that's been made for my device (version 3.4.113), which is the SM-T805. Is it feasible to develop a kernel from scratch based on Android mainline and then port it to my SM-T805 device?

[ViralGamingandDevelopment]

Quick question before I begin: I have a unique need for an app that requires unrestricted wifi scanning, and google has restricted wifi scans to 4 every 2 minutes. Is it worth it to pursue a custom kernel for this specific behaviour? The organizations that will be using the app are very enterprisey and would have no problem buying a specific watch version then loading up a custom kernel as part of onboarding. Is this feasible or worth it to pursue? Thank you in advance

Where is the kernel source of evolution x 5.6.1? I cant find it :(
