CRUEL KERNEL S10 V2.3
The development moved to this thread. From V3 kernel supports multiple devices.
Introduction
This kernel is based on BTA8 samsung sources. Only G973F device for now. It is possible to use it on BSKO, BSL4, BTA8 firmware. All sources are open on GitHub.
Continuous integration with GitHub Actions is set up. This means you can customize the kernel from browser and build the version suitable for you without leaving the browser (see сustomization section).
Features
Customizable build with config presets
Only part of samsung security features disabled (DEFEX, Process Authentification, root restrictions)
Switchable SELinux (by default it's locked in "always enforcing" mode in samsung sources)
Built-in in Magisk
Wireguard for VPN
CIFS for SMB
Iptables TTL and HL editing modules for bypassing tethering restrictions
Build commands (configuration presets) used for V2.3 kernel:
Code:
$ ./build mkimg name=CRUEL-V2.3-BTA8 +magisk +nohardening +wireguard +ttl +cifs
$ ./build mkimg name=CRUEL-V2.3-BTA8-CANARY +magisk+canary +nohardening +wireguard +ttl +cifs
Installation Instructions
First of all, TWRP Recovery + multidisabler should be installed in all cases. This is a preliminary step. Backup your existing kernel. You will be able to restore it in TWRP Recovery in case of any problems.
Dowload an *.img file and
With TWRP: Reboot to recovery. Install > Install Image > CruelKernel.img > BOOT.
With Heimdall: Reboot to Dowload mode.
Code:
sudo heimdall flash --BOOT CruelKernel.img
With FK Kernel Manager: Flasher > Manual Flasher.
ChangeLog
V1 is based on BSKO sources and was privately used. You can find V1 by the link.
V2 is based on BTA8 sources. nohardening, nohardening2, cifs configuration presets added.
V2.1 is for internal use only (testing release) +nohardening preset activated by default

How to customize the kernel build
It's possible to customize the kernel and build it from the browser. First of all, create and account on GitHub. Next, fork this repository. Switch to the "Actions" tab and activate GitHub Actions. At this step you've got your own copy of the sources and you can build it with GitHub Actions. You need to open github actions configuration file (.github/workflows/main.yml) and edit it from the browser. For example, to alter the kernel configuration you need to edit lines:
Code:
- name: Kernel Configure
run: |
./build config name=CRUEL-V2-BTA8
+magisk
+ttl
+wireguard
+cifs
You can change the name of the kernel by replacing name=CRUEL-V2-BTA8 with, for example, name=my_own_kernel. You can remove wireguard from the kernel if you don't need it by changing "+" to "-" or by removing the "+wireguard" line and "" on the previous line.
Available configuration presets can be found at kernel/configs folder. Only the *.conf files prefixed with "cruel" are meaningful. For example:
magisk - integrates magisk into the kernel. This allows to have root without booting from recovery. Enabled by default.
magisk+canary - integrates canary magisk into the kernel.
ttl - adds iptables filters for altering ttl values of network packets. This helps to bypass tethering blocking in mobile networks.
wireguard - adds wireguard VPN module to the kernel.
cifs - adds CIFS (SMB) support.
nohardening - removes Samsung kernel self-protection mechanisms. Potentially can increase the kernel performance. You can enable this config if you face rooting or some other kind of restrictions. Other kernels usually use settings from this config by default. It's safe to enable this config, it just makes your system less secure.
nohardening2 - removes Android kernel self-protection mechanisms. Potentially can increase the kernel performance. Don't use it if you don't know what you are doing. Almost completely disables kernel self-protection. Very insecure.
nodebug - remove debugging information from the kernel.
300hz - increases kernel clock rate from 250hz to 300hz. Potentially can decrease response time. Disabled by default, untested.
1000hz - increases kernel clock rate from 250hz to 1000hz. Potentially can decrease response time. Disabled by default, untested.
For example, you can alter default configuration to something like:
Code:
- name: Kernel Configure
run: |
./build config name=CruelCanary
+magisk+canary
+wireguard
+nohardening
After editing the configuration in the browser, save it and commit. Next, you need to switch to the "Actions" tab. At this step you will find that GitHub starts to build the kernel. You need to wait about 25-30 mins while github builds the kernel. If the build is successfully finished, you will find your boot.img in the Artifacts section. Download it, unzip and flash.
To keep your version of the sources in sync with main tree (following updates), please look at this tutorial.

geiti94 for showing that it's possible to built-in Magisk into the kernel. Initially I experimented with ASIG kernel, but ASIG+Magisk on ASIG firmware just stucks on boot with an SELinux initialization problem. At that time I doubted that built-in Magisk will work.

If your phone was able to boot to pin screen, then I doubt the problem is in bootloader. Could you try V1 kernel https://github.com/CruelKernel/exynos9820-beyond1lte/releases/tag/v1.0
If it will work, then probably V2 will also work with +nohardening option. V1 compiled with this option, V2 without it. I will rebuild V2 then.

No, it's definitely not related to twrp. Well, I don't know what is an exact problem here, but some guys told me they were able to flash the kernel on ambassadi with data wipe or immediately after flashing the rom itself.
It would be very nice if people will just write if the kernel works or not on their roms. This will be a huge help for me.

+magisk
+nohardening
+ttl
+wireguard
+cifs
+sdfat
+ntfs
+tcp_cibuc
+morosound
+boeffla_wl_blocker
First of all, you need to change G973F model to the model of your phone. Supported models: G970F/N, G973F/N, G975F/N G977B/N, N970F, N975F, N971N, N976B/N.
You can change the name of the kernel by replacing name="CRUEL-V3" with, for example, name="my_own_kernel". You can remove wireguard from the kernel if you don't need it by changing "+" to "-" or by removing the "+wireguard" line and "" on the previous line. OS patch date can be changed with os_patch_level=2020-02 argument, the default current date is in build.mkbootimg.G973F file.
Available configuration presets can be found at kernel/configs folder. Only the *.conf files prefixed with "cruel" are meaningful. For example:
+magisk - integrates magisk into the kernel. This allows to have root without booting from recovery. Enabled by default.
magisk+canary - integrates canary magisk into the kernel.
bfq - enable bfq I/O scheduler in the kernel.
sched_... - enable various (conservative, ondemand, powersave, userspace, performance) CPU schedulers in the kernel.
ttl - adds iptables filters for altering ttl values of network packets. This helps to bypass tethering blocking in mobile networks.
wireguard - adds wireguard VPN module to the kernel.
cifs - adds CIFS (SMB) support.
tcp_cubic - use CUBIC as default TCP congestion control.
tcp_westwood - use WestWood as default TCP congestion control.
sdfat - use sdfat for exFAT and VFAT filesystems.
ntfs - enable ntfs filesystem support (read only).
boeffla_wl_blocker - enable boeffla wakelock blocker module.
morosound - enable moro sound control module.
+nohardening - removes Samsung kernel self-protection mechanisms. Potentially can increase the kernel performance. Enabled by default. Disable this if you want to make your system more secure.
nohardening2 - removes Android kernel self-protection mechanisms. Potentially can increase the kernel performance. Don't use it if you don't know what you are doing. Almost completely disables kernel self-protection. Very insecure.
nodebug - remove debugging information from the kernel.
noksm - disable Kernel Samepage Merging (KSM).
nomodules - disable loadable modules support.
noaudit - disable kernel auditing subsystem.
300hz - increases kernel clock rate from 250hz to 300hz. Potentially can improve ui responsiveness.
1000hz - increases kernel clock rate from 250hz to 1000hz. Potentially can improve ui responsiveness.
For example, you can alter default configuration to something like:
Code:
- name: Kernel Configure
run: |
./build config
os_patch_level=2020-12
model=G975F
name="OwnKernel"
+magisk+canary
+wireguard
+nohardening
+1000hz
After editing the configuration in the browser, save it and commit. Next, you need to switch to the "Actions" tab. At this step you will find that GitHub starts to build the kernel. You need to wait about 25-30 mins while github builds the kernel. If the build is successfully finished, you will find your boot.img in the Artifacts section. Download it, unzip and flash.

How to build the kernel locally on your PC
This instructions assumes you are using Linux. Install mkbootimg (AIK tool) from osm0sis, heimdall (if you want to flash the kernel automatically).
Next:
Code:
# Install prerequisites
# If you use ubuntu or ubuntu based distro then you need to install these tools:
$ sudo apt-get install build-essential libncurses-dev libtinfo5 bc bison flex libssl-dev libelf-dev
# If you use Fedora:
$ sudo dnf group install "Development Tools"
$ sudo dnf install ncurses-devel ncurses-compat-libs bc bison flex elfutils-libelf-devel openssl-devel
# Install mkbootimg
$ wget https://github.com/osm0sis/mkbootimg/archive/master.zip
$ unzip master.zip
$ cd mkbootimg-master
$ sed -i -e 's/-Werror//g' Makefile
$ make
$ sudo mv mkbootimg /usr/local/bin/mkbootimg
# Get the sources
$ git clone https://github.com/CruelKernel/samsung-exynos9820
$ cd samsung-exynos9820
# List available branches
$ git branch -a | grep remotes | grep cruel | cut -d '/' -f 3
# Switch to the branch you need
$ git checkout cruel-v3
# Install compilers
$ git submodule update --init --recursive
# Compile
$ ./build mkimg name=CustomCruel model=G973F +magisk+canary +wireguard +ttl +cifs +nohardening
# You will find your kernel in boot.img file after compilation.
$ ls -lah ./boot.img
# You can automatically flash the kernel with heimdall
# if you connect your phone to the PC and execute:
$ ./build :flash
# Or in a single command (compilation with flashing)
# ./build flash name=CustomCruel model=G973F +magisk+canary +wireguard +ttl +cifs +nohardening
Pin problem
The problem is not in sources. It's due to os_patch_level mismatch with you current kernel (and/or twrp). CruelKernel uses common security patch date to be in sync with the official twrp and samsung firmwares. You can check the default os_patch_level in build.mkbootimg.* files. However, this date can be lower than other kernels use. When you flash a kernel with an earlier patch date on top of the previous one with a higher date, android activates rollback protection mechanism and you face the pin problem. It's impossible to use a "universal" os_patch_level because different users use different custom kernels and different firmwares. CruelKernel uses the common date by default in order to suite most of users.
How can you solve the problem? 5 ways:
You can restore your previous kernel and the pin problem will gone
You can check the os_patch_level date of your previous kernel here https://cruelkernel.org/tools/bootimg/ and patch cruel kernel image to the same date. If your previous kernel is nemesis, patch cruel to 2099-12 date.
You can reboot to TWRP, navigate to data/system and delete 3 files those names starts with 'lock'. Reboot. Login, set a new pin. To fix samsung account login, reinstall the app
You can rebuild cruel kernel with os_patch_level that suites you. To do it, you need to add the line os_patch_level="<your date>" to the main.yml cruel configuration. See the next section if you want to rebuild the kernel.
You can do the full wipe during cruel kernel flashing
Good job!
Thanks Dev! Does this kernel work also with LineageOS and AOSP roms?

Did you checked it if it works for you? For me the oneliner didnt work in main.yml. I must edit the build.mkbootimg.G975F file and rebuild. Then i got no pin problems cause the OPL was now changed.

Yes, I checked that it works. Here you did't use os_patch_level setting and the date is 2020-02. Next, you updated os_patch_level and you can see the date changed if you unfold "Show information about build" section in build log. In the third commit you removed the os_patch_level and cancelled the build, so the date reverted to default one 2020-02. And in finial commit the date was changed in build.mkbootimg.G975F file. If you doubt the date changed, you can check the build settings either in "Show information about build" section in build log or in "Kernel Configuration Info" file next to the kernel image in "Artifacts". Thanks!

As for now, it compatible only with Samsung based firmwares. Works on native samsung firmwares, BeyondROM, on Ambasadii it's better to use Nemesis kernel (you will face pin problem if you try to install cruel). The kernel doesn't work on LOS.
Anybody want gcam for exynos.. u can see tgis video it for android Q one ui 2.0 for s10plus exynos
I have a question . The hadest rum was established, respectively the hadest kernel. I install the cruel kernel, but after the reboot the kernel of the hadest returns. Why? The first time I encounter this phenomenon, How to solve the problem?
Before rebooting the cruel core, the necessary functions work. After a reboot, the hades kernel returns.
@evdenis
I got problems with your latest sources (3.0 and 3.1). It doesnt boot to recovery with an app. This works for a few commits earlier(last week or so). Now its not working. And the OSPL in main.yml doesnt work for me too. Doesnt pass the restart pin. But thats not a problem, changed it in the other side.
Cant test your compiled versions, pin problem, i was on nemesis kernel, so i have to compile it myself.
Another problem ive saw, the device doesnt shut down. It only reboots. Compiled with 3.0 and 3.1 sources. With the older source a week ago, it works.
Edit: So tried your released v3.1 and changed the OSPL manually for PIN Fix, seems to work(recovery and shutdown). Maybe something went wrong on my side till compiling. Have no clue atm.

This could be due to enabling non-default configuration presets, like +nodebug or +nohardening2.

Hades rom uses very good kernel. Technically, I don't see any reason to change it on hades rom, unless you really want to experiment with, for example, +1000hz or +bfq scheduler.
The reason the previous kernel restores back could be again due to patch level mismatch.
I will update installation method in the next version to dynamically repack kernel during installation procedure. Hope, this will solve os_patch_level problem (pin issue) once and for all.
nice kernel
Thanks for this wonderful kernel! It is an honour for me to be able to participate in this!

- LA.UM.8.3.r1-08100-sdm845.0 CAF Tag, Why 8100 only and not newer ? Because it performs the best, i've tested even Android 11 tags, it performs worse, this tag is more efficient for battery life while maintaining same performance if not better;

- Cache improvements;
- Scheduler Improvements;
- CONFIG_HZ = 250;
- 128kb Readahead. Why ? Because thats the default value in linux and pixels as well;
