[REQUEST] [KERNEL] Galaxy E5 Permissive Kernel (SM-S978L) - Galaxy E5, E7 Q&A, Help & Troubleshooting

This is my official request thread asking for help with making a permissive kernel for my phone. I can not find a copy of my phone's kernel source via any outlets and have been limited to unpacking and repacking the boot.img myself but I am limited to the very phone I am working with, no PC or anything.
If someone could please help me out, that would be greatly appreciated.

[DEV][TEMPLATE] Kerneller - Modify Ramdisk, dt, zImage, and SELinux on the fly

༼ つ ◕_◕ ༽つIn the name of our great lord Helix!༼ つ ◕_◕ ༽つ
Kerneller, a flashable Zip template for ramdisk modifications
Google what a kerneller is​
Many of you have no doubt heard of osm0sis' Anykernel2 and previously koush's Anykernel. Kerneller is an alternative designed solely around Sony's Xperia lineup, taking into account the 'recovery-inside-ramdisk' situation we've found ourselves in. However, the script should also support other devices such as Nexus. (I say should because I can only test on the Xperia devices I own -- if anyone could help test, I would be very grateful!)
And with the release of Android 5.0 Lollipop, users have been facing a dilemma: To download a permissive or enforcing version of the kernel? Kerneller fixes that issue by combining the two in a single zip using a slightly modified version of keycheck, allowing the user to choose what will be installed at the time of flashing.

Any questions, tips, or comments are welcome!
Credits & Thanks: All authors of the included binaries. osm0sis for AnyKernel2 and porting the binaries. koush for the original AnyKernel concept. Everyone who helped test. Myself5 for the inspiration and oshmoun for the help.

I'm glad you like it but I can't say that's the reaction I was expecting lol. Please do let me know if anything bothers you though.
Just by the way, I moved the thing into its own repo and added a small script to compress and sign it. Cheers!
work for lock or un lock?thank you

I'm sorry to say I don't understand the question. This script cannot lock or unlock anything.
It modifies the boot sector of your device. For that to be possible in the first place, you need an unlocked bootloader.
thank you,Im lockbootloader now,and that's what I want to know
Sorry for noob question,but where to download?Cant find the link.Want to try this on my m2 aqua.

Your best bet would be using 'git clone', though you can also just download the whole repo as a zip file (here, if you're having trouble finding it). Note though that the packing script won't work in Windows unless you have a *nix shell emulator (such as Cygwin or win-bash)!
You can still zip the thing together yourself using 7zip or WinRAR, however it will not be a signed zip (so some recoveries -- like Cyanogen Recovery -- may refuse to flash it, but you could use the bash script to figure out what you have to do in Windows to sign your new zip).
If you do eventually get it to run, I'd be very glad if you could send me the recovery.log of the flash via PM!
TouchWiz?
This tool works on touchwiz Lollipop 5.1.1 Roms or not?
Stock kernel is Enforcing and I tried various methods to make it permissive, nothing works

I don't know if your device's boot image is assembled using mkbootimg (like Nexus devices). If so, you may be able to.
But you'll need to pack the device tree binary and zImage into the zip (just use unpackbootimg).
So, I'm very confused, I usually build boot.imgs right out of the AOSP source code... how could I leverage this?

It's not really meant for people who compile ROMs, but more for kernel devs or testers who only compile the kernel.
Instead of always having to extract the ramdisk from boot images (whenever the ramdisk changes, which we kernel people can't know and check for every single kernel, nor do we care) and then using mkbootimg (meaning you have to release one boot image for every ramdisk you need to support, i.e. if you want to support ROMs with vastly different ramdisk implementations, where mixing ramdisks would cause a bootloop).
With this, you go around the problem. Compile the kernel outside of the ROM tree (which takes a few minutes vs several hours that compiling the entire ROM can take), grab the zImage-dtb (or adjust the script to use zImage + dt.img), and package the thing together. (There are options to also include kernel modules in the zip, and scripts that will compress and sign the zip for you.)
The highlight of this project used to be being able to switch Selinux status when flashing the zip, instead of adding androidboot.selinux=permissive for each boot image, and then uploading two images. Nowadays compatibility of this switch with various devices and Android versions is questionable (I can't test personally because of how limited Xperia devices have become recently -- the 3.10 kernel does not work with enforcing selinux), but the core idea of using it to avoid having to create boot images is still alive and kicking.

Please Help

when i use dt.img and zimage extracted from other dev TWRP for my device and use it as prebuilt kernel for my TWRP compiling its working but when i compile TWRP from kernel sources and its not booting what is the reason? or how to solve it?
Currently im doing it on Grand 2 but i wanna learn my own thats why creating TWRP by myself. Help please.

bootloop on kernel build from source

I am new in kernel developing and i started learning development by compiling kernel from source for samsung j3 pro (2016). I downloaded its kernel source (J320F / LL swa INS ) from samsung opensource site And gcc toolchain arm-eabi 4.8.
I followed available guide on net step by step for compiling and i its successfully compiled without an error and my zimage is created but when i flashed this kernel i got bootloops.
ANY SUGGESTIONS IS GREATLY APPRECIATED
i getting error on making modules too. I searching fix each error.
I enabled module in menconfig but failed to make
I have also compiled kernel available on github for j320fn with variant-defconfig for j320f but same result.
Any one have knowledge about this please instruct me

Kernel Compilation procedure

I am new to android kernel build stuff. So please forgive me if this is not the right platform to raise this query.May i know the steps involved in building the kernel? I am trying to build the stock kernel updated by oneplus in github. Any help or supporting links about kernel compilation will be of utmost help to me. Thanks!

Kernel devs most likely uses scripts to compile their kernel which you can probably find in their github and adapt for yourself

[Q] [SOLVED] Building OOS13 Kernel - Finding defconfig ?

I am trying to build the latest OOS 13 kernel .
The source I am working with is https://github.com/OnePlusOSS/android_kernel_oneplus_sm8250/tree/oneplus/sm8250_t_13.0.0_op8
In the past , i've built for Samsung and Lenovo devices , although I am unsure of a few things with our oneplus8t
Which defconfig file should I be using? as I do not see a kebab config within the root directory of android_kernel_oneplus_sm8250 or arch/arm64/configs/
Google has helped , but not too much material on building OOS kernels
What is the difference between a OOS kernel and AOSP kernel ? Would I be able to take a commit from AOSP and apply to my OOS ?
Appreciate any insight , and hope to be able to release a kernel soon!
SOLUTION
Backed up my boot.img with ex-kernel manager . Brought the boot.img to my build folder. Extracted defconfig with extract-ikconfig
Hey Dude I'm on oos11..i wanna compile a new kernel..which debconf to use.. the one in the vendors or what? Kona-perf.debconf?
Please help me which debconf to use for OnePlus 8
@hightech316 any luck on building the custom kernel yet?
