[Q] OmniRom 4.4.2 Kernel

Ok guys, the rom is awesome. Installed it on my HTC One... But: Changing the Kernel is really hard and you cant enjoy it... cause of one bad bug.
First, i installed the ElementalX Kernel for 4.4.2... jep, not usable... graphic-bugs whilst opening apps. Also the start-menue (reboot, power off, etc...) doesnt display itself.
There are black stripes all over the lower part of the display...
Okay, restored the default kernel: Everything good.
Installing all other 4.4.2 HTC One kernels: Same bug every time...
Is there any way to install kernels without this damned bug?

Kernels other than the one included with omni are not supported, as the team can't test every kernel in existence.
If there's a specific feature from a kernel you want, it can be submitted to code review: http://docs.omnirom.org/Main_Page - read the items under Development

[Q&A] [KERNEL] [SM-G900F] [CM12/CM11] Boeffla-Kernel 1.0-beta1 (23-03-2015)

Q&A for [KERNEL] [SM-G900F] [CM12/CM11] Boeffla-Kernel 1.0-beta1 (23-03-2015)
Some developers prefer that questions remain separate from their main development thread to help keep things organized. Placing your question within this thread will increase its chances of being answered by a member of the community or by the developer.
Before posting, please use the forum search and read through the discussion thread for [KERNEL] [SM-G900F] [CM12/CM11] Boeffla-Kernel 1.0-beta1 (23-03-2015). If you can't find an answer, post it here, being sure to give as much information as possible (firmware version, steps to reproduce, logcat if available) so that you can get help.
Thanks for understanding and for helping to keep XDA neat and tidy!

Many thanks to our Lord for his hard work in last weeks.
Now it is a "real" S5 ))

Sound control?
The Boeffla control app v. 2.1.73 only offers volume adjustments in the Boeffla-Sound section. I tried running the Boeffla Sound Control App v. 1.7.1 from the market as well as a presumably modified version I found on XDA, but both force close immediately. Is there a way to take more advantage of the Boeffla-Sound options on this kernel (2.0-beta3-CM 12.1)?

Issue with CPU and GPU frequencies
Hello...
I have a Samsung Galaxy S5 and i have installed CM12 with the latest kernel 1.0 beta3 and i experience freezes and hot reboots...
I have not overclocked anything as you can see from the pictures and i have left all frequency clock settings at default values, but when i go to CPU-Z i see the values of CPU and GPU overclocked...
In the attached images i have the default settings in Boeffla for CPU on 2457MHz and in GPU at 578MHz and in CPU-Z i see that max CPU frequency is 2.84GHz and GPU is 657MHz...
Why is this happening?
Thank you in advance for your help...

Issue with CPU and GPU frequencies
It is being answered by Lord Boeffla...
All is normal. Tools like cpu-z and others always display the maximum possible frequency, regardless of what you cap the frequency to.
So, it just shows something not correct.
You can verify that very easily by using tools like CPU Spy etc and you will see, these high frequencies are indeed not used unless you allow it.
The reasons is: These tools always assume, when overclocking frequencies are available, they are used. Which is not the case by default in my kernel.

nameless rom KLTE 4.4.4
does it work on namelessrom nightly with stock kernel?
edit- will overclocking freeze my phone? i tried ktoonsez's kernel and it froze my phone. i had to reflash /system and rom, thankfully i kept all my data.

i would like a list of working roms (4.4x) that work on this kernel. ty

Hi! Thanks in advance. Im having problems with the kernel. Im using resurrection rom and this kernel, and Im suffering a battery draining specially when I put the phone off and I go to sleep or something. I can be sleeping for example 6 hours, and later having around 10% battery less. Im using Greenify, Google Services disabled, but somehow I can not have a real deep sleep when Im gone.
Excuse my english. And thanks again.

help me please
Hello and thanks for a great kernel . I have a big problem : the afternoon I tried to convert the partition data and cache to f2fs but i failed . I tried to return to ext4 and seems to have gone quite perfect . Now I can install rom and gapps but not the kernel ( because bootloop ) can you help me ? I'm desperate
p.s: sorry for my bad english

stefan

Flashed the latest beta kernel, reboots after booting and doesn't stop.

Thanks for your work...
Hello Boeffla,
i use your kernels since S3 and i was so happy when i read, that you also support the S5....
I'm very happy with the kernel and i never had problems with the kernel at all (using smoove, interacitve, conservative)!
I really appreciate when you further support the S5 development!
regards Oliver

I tried this kernel (2.1-beta8) on BlissPop v3.6 (BlissPop-v3.6-klte-OFFICIAL-20150701-2254), but some features didn't work (ex: couldn't use tethering).
IMPORTANT: BlissPop is "customized" rom, so you must read and understand when want to use:

Sm 900m
Kernel working with s5 SM-900m?

I would like to test this kernel with Exodus ROM 5.1.1 (http://forum.xda-developers.com/galaxy-s5/orig-development/rom-team-exodus-klte-t3135876). Is it compatible? If yes, how do I know what version of the kernel to take (CM11, CM12, CM12.1, Stock Lollipop 5.0)?
Thanks.

Problems with bluetooth on g900t
I have a g900t with cyanogenmod 12.1 installed. Whenever I try to pair my sony speakers to my phone the speakers do not work properly. So my question is, can I installed this kernel on my g900t? would this fix the bluetooth problem?
Thanks in advance.

Hi, I am new to this. Just got my S5 today.
The phone still got Android 5.0 with TouchWiz on it (original Samsung firmware) and is not rooted yet. I want to install CM 12.1 later. What kind of kernel do I need now? If I install the kernel via Odin is my phone then rooted and ready to install CM 12.1?
Thanks for any help.

I installed Boeffla Kernel and CM12.1 successfully. All works fine. However, my phone always says that I have no root rights. Boeffla Kernel for sure is installed and is showing up in my settings. What can be wrong?

You have to enable root, or to flash SuperSU (a third party, actually the most popular root solution for Android.).
I would actually like to recommend you the stock CyanogenMod root, but I myself am using SuperSU for a while, and I would have to search how to use the stock CM root with 12.1.
So either install SuperSU app from the play store, and download this zip: download.chainfire.eu/supersu, boot to recovery and flash it, to enable Chainfire's closed source root, or Google 'How to enable root on CyanogenMod 12.1' to find out how to use CyanogenMod's own root solution.
Edit:
So I dont have to type everything (instructions how to enable CyanogenMod's own root implementation, IIRC, and if nothing has changed in the meantime, it is Koush's implementation, which is open source:

CPU3: Idle

Hello
After flashing Alliance Rom 4.4.2 i made it show my cpu's status and i noticed that the 4th cpu is idle the whole time, i tried re-flashing the rom again but still the same
And i feel how slow my S5 gets when only running on 3 cpu's
Any solutions?
Thanks for reviewing

Hi there,
This is most likely a kernel related issue/feature that has been included with the ROM. The default/stock behaviour is that the first and last core should always be online. Try looking into kernel managers that may be included with the ROM or from the google play store like kernel adiutor, it may be under the "hotplug" menu. I would look into different kernels or flashing a different ROM if it bothers you too much.

Thanks for replying After your post i did install Kernel Adiutor and i found the offline cpu, when i try to turn it on it just simply turn back off, the other 3 cpu's does turn on an off
Ill post my problem on their foums site
Thanks again.:good:

need a custom kernel

Hi, I have a rooted verizon galaxy s7 (g930v) and i flashed some rom from here that a user uploaded that gives me the s8 icons and some other fancy stuff without too much affecting stock.
I read about getting a different kernel would allow the cpu frequencies and such to be more in your control, and I was wondering how i can go about getting a custom kernel.
The only problem here is, Almost every tut i've seen requires TWRP, and the last time i tried to install it, when i went into recovery booting, i would get in a bootloop, and i last heard it wasnt supported for the s7 anyway.
So I guess my question is, can someone link me a compatible version of twrp (if there even is any for the US variant on verizon), tell me how to install it, and please let me know with a link to a custom kernel that should work on my verizon galaxy s7?, with instructions on how to get it in my system? (I've read everywhere sorry for being a noob with kernels.)
I really wanna work on this and it's been driving me nuts! I would really appreciate any and all help i can get on this matter.
Thank you.

The bootloader on the Verizon S7 is locked. I believe with a locked bootloader you cannot load TWRP or a custom kernel. You are basically stuck with variations of the stock Verizon ROM with the stock kernel.

Damn, well in that case could you answer me this: I want to improve the performance of my phone without losing battery, I know tweaking the cpu and things of that sort could help, but in your personal opinion what would be the best way of controlling such things and their values? I've tried LSpeed, didn't really help, I used kernel adiutor, but one thing i noticed is that i think my system has its own cpu managing techniques, because if i went into kernel adiutor, set the min to 307, when i move my finger it shoots up to 900 then back down, in other people's videos of kernel adiutor i don't see that, any idea on what that's about?
I assume it's something in my system that's making my cpu do that, and i think that's why im not getting the snappy performance I crave. Any ideas?
Appreciate the help btw

Without a custom kernel, you can't tweak the CPU. Can't have a custom kernel on the S7 because of the locked bootloader. So there you go. I haven't tried messing with anything to improve the performance of my S7, so sorry I'm no help to you there.

Custom roms problem

Hello,
i tried AICP, aosp extended, aquarios rom and with every rom i have same problem.
The problem is that every rom stutters and animations lag,they are not smooth. Also when im scrolling between home pages it also lags,simply all animations stutter.I see that all people are having great time on these roms and i think im only one who has such problem. Every time i tried clean install ,but problem persists. I have H870 model.
The only rom that is working good is fulmics for me,it is really smooth but i prefer pure android,like aosp extended,and cant use it. What can i do guys about this? thanks

It's not a custom ROM problem. Have you tried this :
https://forum.xda-developers.com/showpost.php?p=71953461&postcount=22
Or upgrading the adreno drivers? (see the thread about new drivers)

Thanks for your reply. The rom itself has already latest gpu drivers (aosp extended rom),but i installed drivers manually and problem is still there. I realised when i change governor in kernel adiutor (for example from interactive to sched) phone works smooth next 15-20 minutes and then stutter starts again.

OK, good. In the thread mentioned above, there are many people who have no lag. Have you tried my other suggestion? Worked for me and many others.

I will flash later aosp extended and try with force gpu,thanks

Reflash Magisk, clear cache. Clear Dalvik-cache

You mean to first remove magisk with its uninstaller,flash it again and then clear cache/dalvik cache?
