Hi sir. Kernel v2 is good. But i feel faster battery drain in my j700h. May be in nxt update u try to fix it. But over all its very nice and smooth. Thanks
Serious bug found in the custom kernel v2
Initially on stock kernel, when outdoor mode in notification panel was enabled, brightness was set to max for convenient viewing under direct sunlight.
But after flashing the custom kernel v2, as soon as outdoor more is clicked, device reboots. Not just once or twice but every time its clicked. Please fix the issue in the custom kernel v3.
And somebody please upload the stock kernel for the time being. Moreover can somebody please check & reply whether the same issue is in the custom kernel v1. Apart from this, is there way to remove the kernel modified notification appearing in the upper left corner when device gets booted, though it's not a major problem but a bit annoying & eye catchy.
Last but not the least, is there a way to receive regular updates in this rooted J700F. If not then where to manually download the latest updates & flash it via custom recovery.
Looking forward to a positive reply&thanks in advance.
hi i want to ask the kernel source in title say .is for J700F with qualcom chipset but in arch64 i find just exynos chipset files no qualcom so is this for J700H or the two has exynos

I haven't known about qualcomm variant before, so this kernel is for exynos only.
@hensk, I dont have any specific profiles for now, because I'm also testing different combinations.
I tested the at 2.0GHz and performance govenor and I didn't notice any heat.
I recommend 500-1.8 for a15 cores and 200-1.8 to a7.. But you can set limit for a15 200-2.0. At this variant I haven't any lags and haven't notice additional battery drain.

Thank you for the kernel.
Does exynos undervolt well ? If yes please add undervolt.
Hopefully I can squeeze another extra 2-3 hours battery life.
After one day of intense test, the stability its very good, at max frequency too. Antutu confirm my sensation ofincreased speed

to install kernel you require cwm and cwm does flag knox 0x1.
maybe you should make PM direct contact with OP or @modpunk
One little problem I've noticed: the settings that I have chose with synapse, at reboot are changed, maybe by the sistem. How I do for have the choices of new frequencies permanently? Thanks in advance! PS I have tried dvfs disabled with xposed installer but nothing..
Overclocked kernel T530
I have compiled two variants, one for the 4.4.2 rom and another for 4.4.4, CM11 rom.
4.4.2 kernel is tested on the stocklessv5 rom.
The overclocking in this kernel is experimental. Some also claim that overclocking is not possible on this device.
I still feel that there is a speed improvement using my kernel, so whether this comes from the overclocking or from other changes is debatable.
Antutu tests have given me slightly higher scores on the stockless rom than on the CM11 rom.
On stock rom I did get Antutu score at 16800, at the stocklessV5 18367. (these are numbers I have logged a while ago, offcourse results will vary from test to test with antutu.)
On my kernel I typically get around or just below 19000. (highest score so far is 19200)
There is a thread regarding overclocking the LG G2 mini, and I have been looking at the github for that project for ideas.
LG G2 Mini use the same cpu/gpu hardware as the tab4. For comparisation there is posted an image in that thread by someone showing antutu result of 20000 on the LG. But others report they can not replicate that. The LG have lower screen resolution than the Tab4 10.1" so that could explain some of the difference.
About this kernel:
- Overclocking CPU to 1.6Ghz
- Overclocking GPU to 533Mhz
- DVFS is disabled
- Fixed the simple_ondemand GPU govenor crashes
- CPU governors smartassV2 added, enabled interactive govenor
- Compiled with sabermod 4.9 graphite toolchain
For sources, look at github

I have been trying to make one for cm12. But my attempts resulted in a non-booting kernel, so I put it aside for the moment. Perhaps later if I have the time.

But after installing my kernel and I rebooted it just shows the first samsung boot screen, and then goes black, then after a short while it just relaunches twrp recovery.
Other atempts it does go directly to the download mode.
I'm very excited to hear this news. Can anyone confirm if the oc is for real on cm11 or kk? and if so, we must have it working on cm12 for sure. cm12.1 is actually what we're on isnt it? blisspop here, but i see a 5-12-2015 cm 12.1 just dropped so i'm pry gonna run that in the next day or so. Either way, great work! Any type of improvement i see as progress.

hi, please about 4.4.2 with stockless rom v5, if anything become unstable and want go back to previous kernel is it enough to dirty flash stockless rom or there is something that must be deleted manually?
thanx a lot…
thank you can this thing get overclocked more i mean i saw people state they overclocked the tab 1 to 2ghz just asking lol, anyways great job

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)

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.

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.

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.
It may, because tunables are already set up properly by default.

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:

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?

Does this kernel has undervolting capability? Le max 2 has very weak battery.

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.
adb logcat > logcat.txt
adb shell dmesg > dmesg.txt

Hey man, glad you liked it, but at least you could mention the Developers and at least give me a heads-up like "Hey, can i share the thread on the P10 forums?"

It's possible that it's just a matter of drivers, I'll look into it when I have the chance, but no ETA of course.

Thank you so much, take your time, I never ask for ETA.
One question: You'll need the stock drivers? Because I was searching and their are placed into Vendor/lib/modules, so what if I backup my stock drivers, flash your kernel and restore my stock drivers... I'll see if it works
Update: It didn't worked

As confirmed now by @sfoot13 this kernel is now fully compatible with the P10. Separate download link added on thread's OP because both devices require separate compiles.
Remeber this was originally designed for the Honor 9 but from now on it should continue to be 100% compatible with the P10 as all incompatibilities have been apparently solved.
All the thanks to @JBolho :good: he made it possible
Thank you all for giving us a Kernel
I hope you don't mind the question: So it uses another energy management, does that mean there is no 'scrollable widgets freeze' bug?
Yes I could unlock and try myself but it's my daily phone at the moment :-|

If there's such a bug, I've never experienced it, and it's more likely a rom thing, not the kernel fault...
My device is the only one I have and I need it everyday, so... This is not some "alpha ultra experimental thing" that may or may not explode on your pocket, so don't worry
Unlocking the bootloader does force a factory reset though. It's a pain, i know...
I also never had problem with widgets on this kernel and also on stock kernel.
To the actual users: how this is compared with hyperkernel from p10 plus?
Kernel has been updated to v1.2R, new and tuned I/O and updated CPU drivers and Sched Gov.
