FAQ's
How can I enable sweep2wake, sweep2sleep and doubletap2wake in this kernel?
- To do this, first open up a terminal. Then type:
For sweep2wake:
Code:
echo [mode] > /sys/android_touch/sweep2wake
For sweep2sleep:
Code:
echo [mode] > /sys/android_touch/s2w_s2sonly
For doubletap2wake:
Code:
echo [mode] > /sys/android_touch/doubletap2wake
Modes available:
0 - disable
1 - enable
How to set the vibration intensity with ThunderQuake Engine?
- Again, open up a terminal. Type:
Code:
echo [value] > /sys/kernel/thunderquake_engine/level
Values available: 0 - 7
Why none of my videos are playing and I'm having issues with viper4android?
- Just change your selinux mode to permissive with the help of an app called selinux mode changer. Google it.
Install that app, then open it and tap on permissive to enable the permissive selinux mode. Also tick the box that shows you the notification when the selinux mode is changed.
That's it, now after every reboot selinux will be set to permissive and all those issues will be gone.
Help me! This bug has caused me XYZ issue!!
- Simply take a logcat of the issue and then post it here.
Little OT is OK, but go too far and you will get a warning!
Thanks

Gonna try it soon, any plans on adding LG like KnockCode feature??

Plz compatibility with other roms

I love you. I'm glad you another kernel for the condor . You compiled it with any toolchain ? And d2tw is freezing the screen as in zapdos ?

Will this work with AOSP based roms?
Thanks for brining this for condor.....

Great,maybe u can try to add overclock and undervolt?Thanx
STAY ADDICTED!!!

Great work.

Woww, another Kernel for our Device, gotta try now

Unfortunately gave bootloop in slimsaber . If you like to install as the others ( zapdos , phenomenal ) I think it will be compatible with all roms . But since it is already a big project.

Tried on Sokp, Bootloop Aosp roms not supported i think......

Works great on latest AICP 10.0,no issues till now.
STAY ADDICTED!!!

@NV-Dev is this based on Linaro?

One Kernel based on Android 6.0 kernel source. I want to keep this kernel as simple as possible but much power. This kernel is best in its class.
F.A.Q:
1. My device rebooted or crashed, how can I help?
A: Get me /proc/last_kmsg on pastie.org.
2. Battery sucks, my device is not entering deep sleep. FIX PLOX!
A: Fix it yourself, it's an app waking your device up not the kernel's problem
3. Signal is dropping since I flashed the kernel, omg u sucks!
A: The kernel has nothing to do with gsm/cmda signal. Make sure you have the latest radios
4. Do I need to wipe anything when flashing this kernel?
A: No.
5. Does this kernel has X or Y mod?
A: Learn to read, everything you need to know is in the features list, changelog or public repo.

Downloads
v1.0 on Dropbox
All versions on XDA DevDB (soon)
All test builds on Dropbox
Installation instructions
Note: Make sure you've unlocked your bootloader, either by obtaining unlock code from EMUI's website or somewhere else.
Make sure you've the latest version of TWRP. Recommended version
Reboot to Recovery mode by combination of Power+Vol(+) buttons.
Select Install from TWRP screen.
Select KudKernel .zip file.
Swipe Flash button.
Finally wipe cache and dalvik. (optional)
Reboot to system.
Known issues
Don't report issues that are already listed here.
UKSM support is here but not enabled yet due to too many changes on the kernel source...
No hotplug on Interactive governor. Looking for a better hotplug instead...
Usable GPU governors: cpufreq, msm-adreno-tz, performance, powersave, simple_ondemand, userspace
Selecting GPU governors other than these GPU governors would lead you into kernel panic!
Kernel Adiutor will freeze if you go to Entropy section. (probably not kernel related)
If you've problems when installing KudKernel, grab your build.prop and attach it here so I could add support for your device.
Bug reports & feature requests
Please use the DevDB section to report your issues or request feature(s) to be added. Please be noted that:
Bug reports without good explanation or logs are ignored.
Request for feature(s) that could break stability aren't accepted.

If TWRP by @DestructoSphere is able to boot on your phone, it should be compatible too because I'm using his kernel sources.
However, make a backup if something happened after you flash my kernel.

Welcome to hadesKernel
Some personal thoughts:
- this kernel works only on A5 and A7 2017 versions, only for Oreo or Pie and Touchwiz/OneUI based roms (stock and stock based roms) I'm not responsable for what can happen if you flash on other devices/roms/android versions.
- if you take any of my work without my permission i'll report you, and you'll probably get banned.
- you should read at least install instructions stated in this post - i won`t offer support for any issues regarding installation;
- for more info about features included and bug reports make sure you read post #3;
- press 'Thanks' button instead of saying it - it will keep the thread clean and keep me motivated to do more;
- feel free to send me some coffee (which btw, runs out pretty quick) via paypal, if you want to support my work.

CPU governors and IO Schedulers:
Thanks to Saber you can find here more details and usage of each CPU governor and IO Scheduler. Nothing new can be said, he already covered them all. Don't forget to thank him for that.
Spectrum profiles:
As awesome developer frap129 describes here:
Spectrum is a simple, profile oriented kernel manager that allows developers to create profiles to serve to their users. This is useful for users who are inexperienced with kernel tweaking or users who want something that's a single click away.

This means kernel already has inside 4 main profiles to choose from, at a click distance, to fit with your current/further usage.
Profiles are Battery, Balanced, Performance, Gaming.
Spectrum profiles usage:
- battery - low usage like whatsapp/telegram/web pages/movies - mostly for idle usage
- balanced - medium usage/multitasking
- performance - for apps that require more power than usual - medium games or apps with lot of content rendering
- gaming - for high end games and benchmarkings
You can use the settings from spectrum profiles or any other manual settings, via hKtweaks app, thanks to morogoku for integrating spectrum inside MTweaks, based on the most used app for custom kernel settings, Kernel Adiutor provided by Grarak. Don't forget to thank them both for all the efforts they put on this.
Why a separate app? Because i added proper integration for our board and i made sure it doesn't bring incompatibilities.
Values for profiles are calculated based on soc capabilities combined with optimizations.
If you feel lags try to go one profile up, if you reach gaming profile and still lags means that your phone can't handle that content.
To make an idea i will leave below the stock vs profiles settings for comparison:
Stock:
- 345mhz to 1872mhz CPU

- VM laptop mode off
- CRC on
- Fsync on
- Dynamic fsync off - not there in stock kernel
- Arch Power off - not there in stock kernel
Battery:
- 345mhz to 1690mhz CPU

FAQ:
Q: How to report bugs?
A: If you want to report a bug make sure you include:
-device variant / modem version / bootloader version / region
-detailed info about the encountered issue
-steps to reproduce the bug
-logs
Q: How to take logs?
A: Download Logcat Extreme and take a look at this.
Q: Does it work with stock rom?
A: Only if you format data on TWRP before installing - please do note this will erase all your data and internal storage
Q: Why v1.5, where are other versions?
A: v1.0-v1.4 were stock like kernels included in hadesRom Stock. For v1.5 i added too many features so i decided to release as separate. To avoid confusion with older releases i named them v1.5.
Q: Why v1.5 and v1.5s?
A: "s" stands for stock, if you want to have a kernel more like stock you can choose v1.5s version, if you like more features go for normal v1.5.

Another amazing job, keep it up. Going to flash it right now and start saving for sending some coffee soon!

Verification fails at reboot. Do i have to flash the no integrity check,too?
And RMM state bybass ? soft-brick here.

cant root it

Good job @corsicanu :good:
hadesKernel never disappointed me in the past when I used it on my old A3 2015 and now A5 and A7 2017 will profit from it too. Keep it up! :highfive:

good work..thx bro
doas work in stock rom?
thx

Hey @corsicanu, I noticed a bug in v1.5. Indeed when we are in SELinux Enforcing, the wifi can't be turn on while it's work fine when we are in SELinux Permissive.
I'm on hadesrom v4.5 in A520F
PS : I'm french so excuse my bad english ^^

Uninstall magisk, flash v16.0 and then update through the app with direct install. Worked for me.

As Always nothing but Quality, Great work my friend

Hmm, still no SIM card, no service.
I flashed the OREO modem from your other thread, rebooted several times, tried to install OREO bootloader but that fails (because my phone already has oreo bootloader but a later revision).
In system settings it shows baseband version unknown.
What's going wrong here?

Thanks very nice but sad at the same time cause I'm still on android 7

I'm on HadesRom stock v5.0
Should I need to do any wipes before flashing?

can i flash this with hadesRom S9+ Port v1.0?

No need to wipes anything. Just flash the kernel and magisk for root. Reboot and enjoy.

in a720f cant turn on wifi

sorry

This kernel is great. Originally had some battery issues but after adding some xposed modules it back to stock levels or so. By far the best bit is the speed of the fingerprint sensor.
Thanks.
