One more kernel , onemore choose
i flashed it and camera isnt working anymore,pls fix this flashed with rr build
Can you port kernel from mi5 SlimDragons rom ?) they made good kernel )
Thanks, will try it later is it possible to port EAS?
This is the andr68rus link to various extras, included is the link to the flashable remote files

Weird camera works fine for me but I use cm14.
Can you get a logcat?
What camera app and what happens? Just a blank screen?

Ok the problem occurs because both andr68rus and I have named our camera shims differently.
Also lineage has their own name for it.
In this kernel I used the Lineageos naming as I thought that was the standard. (at least I'm 90% sure I did )
@andr68rus please can we standardise on the lineageos naming system and both change our sources to suit?
Once he has updates RR I'll upload the updated kernel and all should be good. Of course since I've wiped my phone to try this out I'll test it first with RR this time just to make sure.

So, will this change make stock camera fully working?
Also, regarding signal reception
at my desk the signal is weak
any idea if we could make signal reception better,
as per my experience LOS based roms or Mokee feel like does not have stock like signal reception feature,
feels bit unstable(always trying disconnecting/connecting)...
which causes the main battery drainage(dual sim, both weak signals)

Tks for ur hardwork, hope u can fix this on the next update bro! I really want to use the kernel, or is there any way to fix the camera problem? Also the flashlight cannot turn on, currently im usingI andr68us's DU build
Hi:
Where is the kernel?
Where can I download the kernel?
Thanks for your job
infrag said:
Thanks to @mosimchah for his hard work on Blackscreen kernel. I've just ported it to X2.
BlackScreen is meant to give you great battery life and performance (depending on how you tune it , more on that later in the second post).
Please read original thread for details.
https://forum.xda-developers.com/le-pro3/development/kernel-blackscreen-pro3-aka-zl1-x727-t3594976
Whats working:
this space intentionally left blank
Fixed Ambient Display
Added in stock LeEco charger settings to fix OTG & USB headphones.
Whats not working:
Dodgy camera as every other X2 kernel/rom atm.
I doubt IR works. Someone want to supply me a .zip with it so I can test? (I cant be bothered extracting)
Install instructions:
Download .zip
link removed while i check camera...
Flash in twrp.
Reflash Root?
Use Kernel Adiutor from playstore to change kernel settings or anything else that tickles your fancy.

Nice work, thanks I will use LOS naming system next build. I will repack kernel with my ramdisk and put link for < 05/09 RR-N.
PS. Where I can download kernel?
Hope this kernel gets fixed soon, you're doing great work on the Le Max 2, thanks for your contributions!
Also hopefully you and @andr68rus find the naming fix and that this kernel gets integrated into RR, AOKP, DU and the rest of the Nougat roms, I can see it being a great SoT fix for Nougat ROMs.
( for me this kernel is hopeless ((( my problem with camera on nougat roms seems unfixable for now (((

I pulled the link as it didnt work on Cr3pts Unoffical LAOS cm14.1 either.
However it turns out he hasnt updated his libc shim name either so I've re-added the download link.
Wheres your new link so I can test on RR?

No it wont fix stock camera. I didnt imply that so...
As far as signal reception goes I dont have issues with reception.
I do see some stuff in the logs about disconnecting reconnecting and i'll probably have a look at it one of these days. Not sure IF I can do anything but I'll try.

Whats your problem on Nougat roms?
I think I read something about focusing or something?
If so I have an idea but you will need to pull some logs while camera is semi working for you.

PS: arise fix
Open up a file manager and go to the root folder. You need to have SuperSU installed for this
You'll see a folder called su, go to /su/su.d
In this folder create a text file, label it as "permissive.sh" and put the following code in
Code:
supolicy --live "permissive *"
Then save the file and go to recovery and flash arise and Dolby Atmos addons again and then reboot
It should now work

Or
http://srv1.botstack.host:9000/oneplus/op2/custom-kernel-for-haruhios-v3.8-STABLE.zip
This is a project that started as a kernel for my ROM and that is what it's going to be
It can be flashed on other ROMs too and I will gladly provide support however I can't guarantee results
Do note that this is a "secure" kernel. It has many of the security patches merged from CAF and selinux enforcing is forced with no way to go to permissive
What about v4a?
Get SuperSU and input these lines in a terminal
Code:
supolicy --live "allow mediaserver mediaserver_tmpfs:file { read write execute };
allow audioserver audioserver_tmpfs:file { read write execute };"
Wait for a few seconds, swipe away v4a from the recent apps list and launch it again. It should now work
Why isn't a thermal throttling tweak included inside this kernel?
Well in my usage the kernel is so fast that thermal throttling modifications are not needed. You can apply if you want
Currently known bugs?
Nothing
OMG you're copying boeffla!
Relax. I used boeffla's anykernel base as I was in a hurry and didn't have time to make my own zip. Also, boeffla's anykernel zip is one of the best around trust me
What are the features?
Too lazy to write, check back here in a few days but there are quite a lot of features you're gonna like
I'm a nerd, I support the GPL, I'm gonna take you down because you didn't release the source code and neither did you tell me whose toolchain you used!

Camera bug fixed!
I don't usually gamble but when I do I buy note7
May we have two versions? A reverted version for the camera and the current one...? Some ROMs are behind and are not working properly with the new commits about camera. Sorry if I am saying something wrong. I am a noob on these

If you start the camera, my kernel fails to turn it off so the camera will be unavailable for use after the first time you use it and you'll have to reboot

Kernel has been updated
All known bugs squashed!
Seems cool but an enforcing only kernel has its downside for me. I'm not sure if arise works with an enforcing kernel, would love to see a permissive version as well.

Hi got your quote on bens kernel page @anupritaisno1, could you explain me more about this kernel. I guess it will break the focus of my camera due to some new commits, etc as bens kernel v5 had done the same to me. Also, as im using bens RR Rom, will this have any bugs or side affects with that rom (i had flashed boeffla kernel and had to face a lot of problems on his rom such as the xposed modules becoming inactive or not performing after some time, etc.) and last main thing, idle battery drain

Finally someone developing a different kernel! Very much appreciated!
Take a look at ExtremeKernel, it adds some bits missing from stock Kernel that would be nice to see here (Extreme seems to be discontinued).
Gonna follow this thread and try it!
@bodafranus thanks for a great kernel! Working here o a40 sd 415 indian variant. Here one bug though.. touch response is not working on ambient display.. it has been fixed in latest commits by Karthik. Kindly include these fixes in next version. Thanks!
Waiting for Alpha1 to try it! When will it be available?
Changelog seems to be promising!!
New version:
alpha1
1. changed governor and HMP scheduler values.
2. added bw_hwmon shenanigans to ramdisk (responsible for controlling some bus frequencies)
3. updated some drivers
4. merge 'caf/LA.BR.1.2.9_rb1.12' (kang from: karthick111)
If you experience any problems, send logs. (some can be found at: /sys/fs/pstore)

It seems kernel is not fully compatible with vibe k5 a6020a40 sd 415 Indian varient. Phone gets booted only if flashed over hyper kernel of prateekchaubey. But if lm kernel is flashed over stock lineage kernel, phone gets stuck at bootlogo. I checked both alpha0 & alpha1 versions after I got this. Logs from sys/fs/pstore has been attached which are after flashing alpha1 over hyper kernel.
And touch on ambient display is still not working with alpha1 version.

That's strange, can you try flashing over latest official Lineage, after a Factory Reset wipe?
Try to grab a logcat while in bootloop, if it persists (see: https://forum.xda-developers.com/showthread.php?t=2274119)
I will check Ambient Display after I fix some issues.

Ok.. I tried it on official lineage 10/4 build with fresh flash and the lm kernel alpha 1 is working without any problem like bootloop/stuck to bootlogo.
i am not using this kernel even not other, but having big trouble with lineage OS, basically cpu core bug i can say and i asked on its respective thread, page 72 and 73, dev and other users helped me but partially solved you can refer if you want to, but i will explain anyway here shortly,
i am using 20170410 built, and kernel adiutor, selinux permissive, i tried switching all possible options like core control, clock speed, governor, other thing, the only thing bug me is governor, like interactive and ondemand, max 1497mhz and min 200mhz i set, but it always on 1497mhz when even idle little process and core directly goes offline when no use, and never downclock, i also found too much over heating when any games or heavy task.
(**this is not bug of this kernel,
and this exactly same paragraph i'll be posting on lineage os thread, so if you like to suggest me about this bug you can in that thread )
so back to main track, will this kernel solve this problem?
also i see alpha 2 change log but no built.

Wrong thread. If you demand CPU power obviously it'll deliver, so expect it with heavy tasks. Overheat is a problem inherently of our device and its chassis, after all metals are good heat conductors...
Check your target_loads and background processes if you encounter this problem while idle.

really appreciate , i am gonna try this right now and sure will giving you some feedback, thanks.
quick feed, changes i see. A46 device
- little cores working very good as expected now, clock speed interactive as on demanded, which i prefer.
-but big core just stay at 1497 mhz constant (which i know its not problem on this kernel, it from lineageos rom that why i tried using this kernel to see fix) but i know someday may be solved by this kernel,
-one more thing i notice on small core, as its clock speed is as on demanded, but all 4 core speed same, instead of individual.
-now no core get automatically shutdown, even if no demand of an individual core. which is good as well as bad (i am kind of confused for this)
that all, this changes i looked as after flash just now.

actually, its kernel adiutor doing, when i used cpuz, it showed all cpu at 200mhz which i set, and kernel adiutor need 2 full speed core to work smoothly, so kernel throttles to max clock speed of all 4 big core, instead of 2,
so far i am happy, thnks :good:

How is the battery usage in this kernel
This kernel fixes the TOUCHSCREEN FREEZING bug when playing large games by removing the CGROUPS.
Which also gives us back the RAM it ate (458mb total, now)
Same features with LahKeda's overclocked kernel.
1200mhz Overclock
Kernel Sampage Merging
zRAM
Governors
No bugs.
Source
Credits:
@psych.half for the source
@LahKeda for adding overclock and compiling
(no credit for me. I just found out cgroups is buggy but all the work was from them)
thx so much ive been waiting for this for so long
New Build
Increased zRAM from 92mb to 134mb
Properly enabled KSM (It was included in the previous one but it wasn't enabled by default)
Compressed into boot.img
Set the maximum frequency to 1200mhz by default
Set the minimum frequency to 600mhz by default
Set the governor to "ondemand" by default (If I set "performance", the frequency will only go to 1000mhz even though the script was 1200mhz. I don't know why that happens)
So which kernel is better?... Cm11's default one or this one?
Please provide the sources

Tested on SlimKat but it "should" work on cm11 since the source is the same. Try and report back if you can.

@RJinxed
Tried it on corpish's last cm 11 build and works fine..
Actually earlier I was using this kernel in slimkat:laugh:
Just bcz of few bug's!!! I reverted to cm 11
Anyway works on CM 11
Thanks again
New Build
Added 1250MHz overclock (no reboots, see uptime)
Enabled memory control cgroups (enabling cgroups fully was causing freeze in playing games so I tried using just the memory resource controller and it works without freezes, cheers)
P.S. Tell me if you guys want governors. I forgot to add it. Only performance is in this kernel.
Nevermind. Here is it. Same as above but with governors.

To be honest, I don't know. All I do is follow lahkeda/corphish's commits in their github. I just learned to edit defconfigs and compile but aside from that, I don't really know what to do.

I've never compiled kernel for star but for my other device I did
I'm happy to learn stuff :laugh:
Anyway I was never successful enough to upstream my kernel hope u'll be able to do it in future:fingers-crossed:
BTW thanks for the kernel

Hey buddy, I have installed CM 14.1 custom rom. Will this kernel work?

No, this is only compatible for kitkat roms. Also, don't use cm14.1 yet since it's still really buggy.

Can u suggest the best custom rom for this phone?
EDITED: Freezes at 1.3GHz after over 30 hours. If you still wanna try it, I'll keep this here. This build has lowered voltages.
I don't know if I can find a way to get it to work but I'll try anyway.
Final Build
Lowered voltages (Battery life increased)
Updated lowmemorykiller driver (cherry picked from this source)
Unfortunately, 1300MHz was unstable no matter what. Tried different sources, adjusting voltages etc but it seems to be the limit for this device. Also ive noticed some weird artifacts whenever I use it (Which proves that it is unstable since in PC overclocking as well, the cue for unstable overclocking is artifacts)
TLDR; 1250MHz is the farthest we can have.
Deleted. I'm losing my mind.
Try this guys. 1292MHz, Hopefully this would be the last build, After almost 4 days constant, still no reboots.
Edit #1: DO NOT set the governor to ONDEMAND. Performance is perfectly stable but when I set the governor to ondemand, after a couple of hours it rebooted. I don't think this is coincidence with over 100 hours of uptime.
Edit #2: Reuploaded the kernel but this time, performance is the only governor option since it's the only stable one. If you want governors, download the 1250MHz version.
how to overclock
hey buddy,
I have a question, I have rooted my phone it is running android version 4.1.2 and i want to overclock my phone. Can i use this kernel in my existing os version or i have to install cm11 and then overclock it. Please tell me in detail, i am new in rooting and flashing and all that. Please explain in as much detail as possible. Hope a response from you.
Thank u
My model no. GT-S5282
This kernel is the result of a common work with @Leicxan. It can only be used on H990 and was successfully on single sim AND double sim variants. D.O.T.S. kernel is :
- Dirty Santa rooted
- Optimized
- Tweaked
- Stock based
Caution
Nor @Leicxan nor I are responsible for any damage caused to your phone. Any of the action you'll make to flash a kernel theorically voids your warranty. If don't accept any risk, then keep your stock phone
Content
- Based on v10g official LGE sources
- Compiled with UBERTC 7.x Linaro 7.2.1 (since V1.4)
- Dirty Santa root as implemented by @emdroidle
- CPU Governors : performance, powersave, userspace, ondemand, conservative, interactive, darkness, nightmare, zzmove, blu_active, elementalx, chill, dancedance. Default is interactive.
- I/O Schedulers : noop, deadline, cfq, fiops, sio, bfq, zen, maple. Default is zen.
- TCP congestion protocols : htcp, cubic, bic, reno, westwood. Default is westwood.
- Adreno idler
- Adrenoboost
- Exfat Support
- KCAL
- RCTD removed
- Wakelocks management
- Various small optimizations and tweaks
History
V1.0 [11/10] : original version
V1.1 [11/22] : CPU frequency hard limit (for battery drain improvement) and various minor fixes
V1.2 [11/27] : CPU frequency fix, exfat from samsung's open source module, LGE adaptive readahead
V1.3 [12/11] : Upstream Kernel to 3.18.86 thanks to @thirdzcee. Disabled LGE's rctd, ccmd and triton. Disabled some debug configuration. Note : Windows Defender can detect the archive as a Fuerboos trojan, this is a false positive.
V1.4 [01/04] : Fix for kernel crash when using pptp vpn. Upstream Kernel to 3.18.90.
Installation instructions
Follow the instructions provided by @emdroidle here : https://forum.xda-developers.com/v20/development/dirtysanta-h990-t3624296
At step 16, instead of typing fastboot reboot, just unplug the usb cable, remove battery, wait 5 sec, put the battery back and reboot the phone. This should limit the risk of static screen at reboot.
Once the kernel installed, update your phone to the latest KDZ for your region using KDZ Writer : https://forum.xda-developers.com/v20/development/tool-kdz-writer-t3649818
Known bugs
Some users reported issues with SD cards formated with exFat. This is not a general issue. The root cause is not clear (linked to the way the SD card is formated ?).
How to report a problem
It is very important to provide as many details as possible when you report a problem. It means providing :
- the model of your phone
- the version of the kernel and of the KDZ you updated to
- a precise description of the problem and of the circumstances
- logs (logcat & dmesg) : https://forum.xda-developers.com/showthread.php?t=2185929
Q&A
Before asking please :
- read the posts in this thread. The "Search Thread" box is your friend.
- have a look at @xdav20's H990DS Info Bank thread which is full of usefull information : https://forum.xda-developers.com/v20/how-to/h990ds-info-bank-t3703736"
Thanks
@emdroidle for his implementation of Bad Santa on H990
@USA-RedDragon for his werewolf kernel that was inspiring

Can we flash this over an existing kernel via TWRP if we have already rooted?

Normally yes.. But if there is a problem, you'll have to restart all over, so make a backup of your phone, just in case..
It would be nice if this can be crossed over to H918.
First of all, just want to say thank you to @jahlex and @Leicxan for bringing the long awaited kernel with literally everything I could ask for to our devices.
Upon first install by flashing in TWRP, wiping dalvik/cache and rebooting, my phone goes to the LG screen, then black screens and I get a kernel crash screen that I've taken a photo of here
Any ideas what's causing it? My system version is in my signature. I'm really keen to get this working! For now I've restored my TWRP backup I did before flashing, back to 0.2.3b
Update: Even after the TWRP restore I was still getting the same problem. Immediately I thought it might be a Magisk problem as that's the only other thing I updated before rebooting. It appears I was correct. I used KDZWriter to re-flash the boot & system partitions of my phone (since Magisk modifies the boot image) and it immediately booted okay with my TWRP backup. Booted back into recovery, flashed the kernel as well as a previous Magisk version (14.0 not 14.2) and my other /system apps & mods, wiped cache, rebooted and sat on the LG screen for a while. Then booted into the OS okay. Glad it worked out and I'm keen to see how this kernel goes.
On a sidenote, do you have any plans to bring it to a more up to date version of the linux base kernel?

Magisk 14.2 and 14.3 are beta version, I tried magisk 14.3 but my h990n always boot into bootloader interface..
So just stay with magisk 14, it doesn't have any issue.
For the Linux version, it will take tons of time to do this even we just upstream our kernel (from 3.18.31 to 3.18.79)

Yeah I don't know why 14.0 prompted me to update to a beta version. I know 14.3 added something to do with supporting LG devices better, maybe that broke something. Otherwise I'm quite happy with how things are going ?
And yeah I'm somewhat familiar with how long kernel related things can take, it was more of a question if anything.
I've just installed it now, it works perfectly for now much more reactive i've impression Thank you!!

Or is it newer ?

This is major evolution of this kernel. DirtySanta-h990-1.2-u721-v10g was basically the stock v10g kernel with Dirty Santa root.
Before all, thank you so much guys, that's a great work
For some opinions i have many friends that buy h990ds last year and me too, we concluded if tha kernel was more optimized battery side was more effective than performances, and will be great that CPU and GPU clocks and voltages will be more unlocked if you can do that , thank you again.
great kernel thank you @jahlex :good: and @Leicxan :good: it works perfectly

They've already enabled some overcooked frequencies with this, as seen in their Github commits. If it's battery you're looking for, install the AKT Profiles from the thread, and then choose a balanced or battery saving profile. Since installing those and this kernel, I'm regularly seeing 5-7 hours of screen time.
On a side note @jahlex or @Leicxan if you're looking for a beta tester, feedback, or Guinea pig to help out (that isn't actually building the kernel, that's above my ability to simply modify individual files) I'd love to help wherever possible
Been doing the whole TWRP/Flashing/Kernel/ROM thing since I got my G3 way back in the day.

As @iDefalt said, we already enabled higher max frequency / voltage for both CPU & GPU. We won't go higher because the result would be high risks of unstability and overheating. If you want performance and do not care about battery life, simply switch to performance governor for both CPU & GPU. We use interactive CPU governor by default because it is a good choice considering balance performance / battery life (nightmare & darkness are good choices too). You have plenty of apps to do that, example : https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor.

OK buddy. We'll remember.
Thanks!!! And with KCAL, it's perfect! :victory:
Huge thanks guys! Everything works great, even video recording. Great work!!!
@jahlex @Leicxan
Thank you for the release. I will report back any noteworthy issues.
Please forgive me if the following comment may deemed as a thread hijacking. I would be happy to remove it on your request.
I have just started a new thread in time for H990DS users and others, with useful information and tutorials that would potentially answer the most commonly asked questions or the issues sooner or later you would run into.
Kcal is so nice to finally have, thank you c:
Hi, all XDA members, I built a light-weight kernel for our little monster (hammerhead).
My kernel is based on Unlegacy Kernel. I optimized the kernel for best battery life and performance balance. I tested it on AOSP Extended ROM. It should work on LOS too.
Features:
-Intelliactive governor.
-SIO scheduler.
-25mV Undervolted manually from acpuclock source code. (Only for PV2 CPUs)
-More cooler device.
You can download img from Google Drive link. Flash it via TWRP or fastboot.
https://drive.google.com/file/d/1RGqpxZJ5lJve57IJeRHZm-BjMhDGIQIy/view?usp=sharing
Source code: https://github.com/metahex/android_kernel_lge_hammerhead
Awesome, I'll test and feed you back
thanks for your work
Detail please for features? Thanks
For this build, kernel comes with intelliactive governor.
I will add some features and improvements for best battery life and performance. (In next build i will undervolt it and i will add more governors, I/O schedulers)
Changelog:
(v1.0.2)
-Kernel name banner fixed.
-25mv Undervolted for PV2 CPUs.
(v1.0.1)
-SIO is the default I/O scheduler.
Testing
Can someone confirm that kernel works with LOS?
thanks for the new kernel, but no work in DU 12.2 flashed via twrp.
Any chance you could have your kernel fix phonecall bluetooth audio? It's bugged on every custom ROM right now and it's been theorized it's a kernel issue.

Xaif fixed a problem with video recording, you should include it in your kernel.
https://github.com/esa-n/android_ke...mmit/45abf34f6a493b2e918b054bedeec3c4d2003900
How i should flash it?
Like "boot" or "recovery" ?
Its a kernel it goes flash it as a boot IMG
I flashed this with AEX ROM and it hung at boot
Will a custom kernel enable NTFS and exFat support on Oreo?? No ROM currently works why either of those so u can't use my external hard drives.
Flashed 1.0.2 kernel over us 8.1. The undervolt sold me! If possible, and if you're entertaining ideas, I'd greatly appreciate usb fastcharge support.
I've heard the arguments against it, but in two years I'd never had a problem.
Will it work on Nougat (Los 14.1)?
