[KERNEL] Semi-Stock Kernel for Galaxy S8 and S8+ (Snapdragon)

[eddie1.tw]

Reset my device, installed AQG6 OTA and then installed TWRP, the kernel and magisk wihout any issue

---------- Post added at 09:35 PM ---------- Previous post was at 09:31 PM ----------



Any chance to get us a more modern kernel with better battery life tweaks? Or simply compiled with optimized flags?

I follow the steps, reset my SM-G9550, flash AQG6 OTA (didn't flash BL, otherwise "sw rev check fail, abl fused 2 binary 1" error message appears), flash TWRP, flash the kernel (I do not know What is your kernel, so I flash no-verify-opt-encrypt-6.0) and magisk v16.

After rebooting, the screen displays an "Authentication failed," error message, and it will not restart automatically after several reboots.

Can someone tell me where am I doing wrong?

Thanks and many greatful

Alright, I did more confirmation, still no luck.
My phone is galaxy s8 sm-g9500 china mainland variant, snapdragon. I got the source code from here ( http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=sm-g9500). I tried all 3 versions except the HK one.
To compile it, I used these commands:

export CROSS_COMPILE=/home/liu/android-ndk-r14b/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86_64/bin/aarch64-linux-android-
export ARCH=arm64
mkdir out
export OUTPUT_DIR=out
make -C $(pwd) O=$(pwd)/out KCFLAGS=-mno-android dreamqlte_chn_open_defconfig
make -C $(pwd) O=$(pwd)/out KCFLAGS=-mno-android -j16

Then I got the 'Image', 'Image.gz' and 'Image.gz-dtb' 3 kernel files. Next, use the 'mkbootimg_tools' from github to unpack the stock boot.img, edit the files in ramdisk, and repack the boot.img with one of the image files. I tried both 'Image.gz' and 'Image.gz-dtb'. The first one boot into download mode instantly, the second stuck there, both of them are shown a 'kernel is not seandroid enforcing' message. It doesn't show any hope to get work...

Hey how did yoıu solved The issue.Same I am trying for note 8 HK variant.

Haven't found any solutions yet... I've stopped the pointless trying for now, cuz it doesn't seem to work without modifications to the code or the Makefile, I think.
Right now, there're two cases that may be helpful for me - either if I can find someway to make a patch to the linux kernel to let it save the boot logs into a file, so it will show what the hell is going on; or someone may send me a boot.img for the mainland variant, which is compiled in the same way that worked for HK variant, then I will check if it'll actually work and maybe can get some new clues?
As always, ANY help would be VERY appreciated.

there are two devs tomtolei and aurora rom's devs they are compiling their own kernel from the source of these snaodragon devices.There is some kind of security or signature s check feature on the codes it prevent to boot I think .
I contacted lots of dev but they dont want to help.So I didnt contact tomatolei because he have premium rom so I dont think so If he want to help.Do you have telegram or smthg?I am keeping resaearch lets work together.My custom rom work stopped beacuse of this custom orginal kernel issue.
