Beware! After overclock, you will feel a bit hotter than before and battery drains much faster!! Flash it at your own risk.
What you need to do is:
1) Install SDE
2) Get the initramfs from this post (download the kernel+init.zip and extract it): http://forum.xda-developers.com/showpost.php?p=9948644&postcount=1
3) Replace the zImage with the new overclocked kernel
4) Boot into SDE recovery menu and copy the initramfs.cpio.gz and zImage through USB cable
5) Boot into SDE developer OS
6) You should get all your apps here and have superuser right now
You will now have read/write access to /system/ or /data/ ...etc.
Next step: You can download GScript from the market (free) to make some custom scripts to remove unnecessary apps and replace the hosts file, etc.

Oh thanks man! I'll impliment this into my own version of Auron's, yeah there was some confusion about your method, thanks for clearing that up!
Nevermind XD I don't know enough to add that, but Auron heavily uses EXT4 which he compiled into his kernel, which is probably why it isn't working for you, he explains in his topic the things he did or did not do.

Thanks. BTW, it would be good if Auron will release his source such that we know what exactly is changed apart from the EXT4 things.
New kernel updated!!!
Get it at the #1 post
Now, it is EXT4 support and can be used together with $aur0n initramfs !!!
Down-clock to 1100Mhz seems to make it more stable
Thanks man really appreciate your quick work! works perfectly with Auron's
Although I'm curious how that overclock works, I've read up on it and it seems that everyone else is making overclocking modules etc. your solution seems a lot more efficient. Do other people know about it too?
I first though it was just a soft change, something that didn't affect the hardware, but something that just forced the digit 1100 instead of 1000, this doesn't appear to be the case since I get some speed gains in Quadrant
~ benched a 2438 ^^
edit: is it possible for you to change the LOWEST value as well? i'm not sure how it would react but I imagine a 100Mhz/200Mhz feature would save up some standby-battery-usage also is it possible to change the intervals with this method? so that we can get 300/400/500/600/700..1100?
edit2: would it be theoretically possible to compile a kernel with driver support for gamepads and others? perhaps ntfs-3g to mount ntfs external drivers... thinking about this we have usb host on this device and an open bootloader

The most difficult part is to determine how much voltage to be given to each frequency. So, it would take some efforts to study.
In addition, setting too low frequency is not necessary be good because the machine might go into deep sleep and never wake up.
Have you run any Super PI tests (or something similar) to see if there are stability issues with the increased clock rates?
Typically when I over-clock my CPU on my PC I increase the voltages at the micro or mini level (CPU, Front Side Bus, Memory, Memory Controller, etc.). As an example 1.3500 may not be stable but 1.3501 could be. Typically You can find the voltage tolerances typically at CPU manufacturer website (ie Intel for me). of course you also have to deal with the temperature of the CPU and other supporting components that regulate the voltage. I will run a Super PI type application to test stability for a few hours. If it works then dont add voltage.. if it comes back with a miscalculation OR an application/OS crash then increase the voltage by a micro amount...
You are correct when you saw it not performing at a higher clock rate... typically what happens if the CPU does not have enough voltage to perform at the expected clock rate it seems to throttle the execution rate to ensure some level of integrity of the executing transaction..
Unfortunately over-clocking is not a science..

its using the same cpu as a lot of android phones are and i daresay that most of the work (working out optimal cpu voltage etc) has already been done
The question is for non-standard clock rates. Standard clock rates should have well defined voltages.

can this kernel work on a101 or not?
Yes it will work, I'm 90% sure since they tested it on the 70IT and it's working perfect on my 43IT.

While this kernel has been OC, it only allows you to choose higher frequencies. BUT, you can still choose 1000 Mhz as the highest by setting it in SetCPU.
After setting min/max as 1000Mhaz in SetCPU, this kernel is just like any other kernels, except that I have applied some of the newest kernel patches (fix bugs?) so that this kernel MUST be better than the stock one.
Hope you enjoy using it
no no, the problem is that after installing oc kernel(without touching anything about frequency), angry birds doesn't run and asphalt 5 doesn't run well and it closes when init a race...So, what's the problem? I have returned to original kernel(with rooting), and now are perfectly running(angry birds and asphalt5)...

It is quit strange, coz I can run angry birds, dungeon hunter, etc.. very smoothly even when I use 1100 Mhz, have you tried to install SetCPU and set the frequency?
Any one have similar problems?
Working great on my A101! It's subtle, but I do notice a slight performance increase in pocket legends. Keep up the great work ardatdat!
ok so i did it and now the youtube app freezes up with 1100 or 1200 mhz...the video plays for like 3 or 4 sec and than freeze leaving only audio playback.. video plays normal at 1000 mhz and down...
thanks for your sharing
but I can't unzipped the newest kernel

NON DEV ISSUES AND QUESTIONS ABOUT KERNEL POST HERE. THIS IS A WORK IN PROGRESS THREAD
HISTORY
I have been given Permission by the Kernel's Author (Gokhanmoral) to create this thread. Please put your issues or questions you have with the Kernel in this thread. Also functional request should also be made here. The aim of this thread is to filter out excess questions regarding the use and experience from the development thread. The author of the kernel and many experience users\testers and primary dev contributors need to use the Development thread in order to help Gokhan to implement his kernel. Would also request the community to contribute in terms of info to compile a knowledge base if you will. Many Thanks Gokhan and future contributors.
THANKS:

FAQ (WIP)
General
Q: Does this kernel support latest i9100 ROM which is based on android 2.3.5 -2.3.7?
A: Yes, it does.
Q: Can I use this kernel on I9100G?
A: No, you cannot. Only International i9100 and Canadian (Bell Mobility) models are supported (Chinese or AT&T T-Mobile US are not supported). Also, I compile ntt-docomo version for each release but beta versions do not support gps and digital tv on ntt-docomo devices.
Q: Does this kernel support CM7 or any other AOSP based roms?
A: Yes, but it only support CM7 or MIUI based roms for now from 2.0 and above. If you are using another AOSP based Rom tell me and I will support it.
Q. What is the latest version of the Kernel?
2.6.3 is the latest and can be found here:
SiyahKernel Edition v2.6.12 (Please ensure you choose the right one for your phone)
Q. I have an International i9100 can I flash NTT version?
A. Important Notice: the one with "ntt" in the filename is NTT DoCoMo SC-02C version. do not flash it if you have EU version
Q. Where can I get the latest Kernel Source for this Kernel?
A. It can be Found Here: Kernel Source
Q.Are there any Variants based on this Kernel?
A. Yes there is DK SIYAH KERNEL
Q: Can I use app protectors with this kernel?
A: Yes, you can. But you have to flash EnableLogger.zip using CWM after flashing the kernel.
TO ENABLE ANDROID LOGGER USE THIS:
ENABLE LOGGER
TO DISABLE ANDROID LOGGER USE THIS:
DISABLE LOGGER IF IT IS INSTALLED
Battery & Performance Factors
Q: What is battery life like on this kernel?
A: Some have said the battery life has improved. Others said not as good as others, this however maybe down to rogue apps creating wakelocks. Could be the rom is does not take advantage of the kernels features or could be a bad battery. Let's just say your Mileage may vary...
Q. I keep hearing about AOS having a factor on performance, whats all this about?
A. The Android OS using quite a lot of resources. AndreiLux wrote and in depth reference post about this which you can find here: [REF][Rewrite 26/10] What the Android OS usage is and what it's not
Q: What can I do to improve battery life?
A: put your phone into airplane mode or do not use packet data when you are not using it. Check for Rogue Apps and also check for unnecessary wakelocks and close them.
Q: I get random reboots or freezes. What should I do?
A: Make sure you boot in Recovery wipe cache and dalvik, then reflash the kernel. Although the kernel will do this if you apply the CWM.zip of the Kernel. It can still leave data behind.
If you are undervolting revert back to stock values. Then start reducing voltage by.25 and test. If that does not work make a note of:
1. When did it happen?
2. Which rom are you using, can you reproduce it
3. do you have any custom init scripts which changes kernel parameters such as freq voltage or anything else?
Post in this thread and we will try and help you.
Q: My phone doesn't go into deep sleep. What is wrong?
A: Make sure that you have cleared cache and dalvik-cache after you install the kernel. Also, reboot once more after the flashing. the phone doesn't go into deep sleep if it is connected to a charger or to a computer. There may be an application running in the background which is preventing deep sleep. In that case you can check which app causing the problem with "BetterBatteryStats" application (search in Google).
Q: do I need to recalibrate the battery?
A: You don't need to calibrate battery for SGS2. Thanks to Entropy512 to pointing out that our device uses MAX17042 which is specifically designed not to require calibration.
OC/UV and init Scripts
Q. What tools can be used to manipulate the clock speeds of this kernel?
SetCpu : http://www.youtube.com/watch?v=X9Sn4Uz4pkM Just an overview
Voltage Control: http://www.youtube.com/watch?v=XkhBFVUKBTQ Just an overview
No-frills cpu: More Info here about the tool
And Initialization Scripts
Tegrak Overclocking app is currently NOT SUPPORTED by this kernel
Q: What is an init.d script?
A:init.d scripts are the scripts which are executed during the boot time. actually, they are meant to initialize and deinitialize system daemons and manage some startup/shutdown tasks. but in android world they are just "autoexec.bat"s. so, it is a mix of rc.d and init.d directories in linux distros. everything in /system/etc/init.d are executed during the booting process. since it is not standard in every android device,some developers choose to execute files starting with "S" and some execute everything. in this kernel, everything in /system/etc/init.d is executed. you can create a script to change, lets say, voltages, schedulers, apply tweaks, run overclocking daemon or run anything else you can imagine.
Q. Okay how do I start to create my own Init.d Script for the kernel?
A: KWERDENKER has written a reference guide to help you get started. You can find his excellent Guide on POST #2 of this thread.
example of Kwerdenker scripts are also in Post 2.
DROIDPHILE'S NOOBS SCRIPTING GUIDE:
http://forum.xda-developers.com/showpost.php?p=19519757&postcount=10699
Here are other examples of init.d scripts supplied by Fenomeno83:
Another couple of nice init.d scripts created by fenomeno83
Q: where is the interface to change GPU clock and voltage?
A:There is now a GUI to change GPU voltage and Charging current it's voltage control and probably one by Gokhanmoral soon
For Undervolting your GPU use this Script from AndreiLux as a Reference:
Example CWM-flashable /system/etc/init.d/99gpuv script
Q: Which governor is the best? Which I/O scheduler is the best?
A: You have to try them and select the one you like. There is a very good explanation about governors and i/o schedulers here:
http://forum.xda-developers.com/showthread.php?t=1242323
HERE IS DROIDPHILE CONCISE GUIDE TO GOVERNORS
http://forum.xda-developers.com/showpost.php?p=19339524&postcount=10023
More info might help those you get a better understanding for schedulers:
https://github.com/CyanogenMod/cm-k...m-2.6.37/Documentation/cpu-freq/governors.txt Source: Cyanogenmod Githubs
Info about Lulzactive Governor.
http://tegrak2x.blogspot.com/2011/07/lulzactive-governor.html
Q: What is smartassV2 governor?
A: It is a governor to control CPU frequency. This governor has a built-in "profile" similar to SetCPU but the profile has no upper frequency limit. It tends to stay on lower frequencies when the screen is off and scale up very slowly, so screen off will use lower clock rate thus conserve more battery, but it also has a fast wake up feature so that user interaction will not see the lag when switching from Sleep to Wake state.... (So SetCPU Profiles are sorta redundant when using this governor, you can still use SetCPU to OC to higher than default Clock frequency).
Q: What is the best UV settings?
A: There is nothing as best UV settings. You have to find the best settings for your device for yourself. Start by decreasing 25mV on each freq and decrease it every day until your device becomes unstable.
Q. I notice one of the features is the ability of customizing Voltages for Charging?
A. Gokhan has written a script which he converted to be applied using CWM recovery (PLEASE BE CAREFUL WHEN APPLYING THIS, IF YOU ARE UNSURE PLEASE ASK IN THIS THREAD BEFORE DOING IT)
Set AC and MISC charging current to 1000mA - CWM flashable (keeps USB charging current at 450mA)
Q. I read that different frequencies would assist in better battery performance do you have any examples of this so I can use it my script?
A. Bene2K11 Created some scripts which allows you modify the bus frequencies when using this kernel, they can be found here:
3 flashable zips for the lowest, mid and highest bus frequencies
MISCELLANEOUS
Q: Which version is the best?
A: supposedly, the latest version is the best. But if the latest version is beta there may be unstable code in it. testing the beta version and reporting bugs will help me. but it's your choice... try and see... maybe this kernel is not stable for your device at all, who knows... I will not answer any "what is the best?" questions and I kindly ask you not to ask that kind of questions since there is no answer to that.
My Thanks for their contribution to this thread to Gokhanmoral, AndreiLux, ChadouMing, Nilste, Matriak31,Ger5,Kwerdenker,Fenomeno83, Bene2k11,Droidphile

[REF]Init-Script Reference Guide By kwerdenker
MANY THANKS KWERDENKER FOR THIS. REPRODUCED WITH HIS AUTHORIZATION.
Original post from kwerdenker here.
I hope some of you find this useful as a reference for creating your own init-scripts. This contains everything I use or at least remember about the options in this kernel. If I forgot something or made an error somewhere, please send me a PM and I will gladly correct it.
How to use these settings:
If you want to test some settings before you commit them to a script, you can use either the adb shell if your on a pc with adb installed or you can use Terminal Emulator directly on your phone. Remeber to enter superuser mode by entering su in the terminal before you try to set anything or you will get errors. After that just enter the line you want with the values you want to test (if the values are incased in "", keep them that way!). If you want to see if it worked just enter cat followed by the part behind the > of the lines and you will get the values that are currently set. Everything you do in this fashion will not survive a reboot of your phone, if you want to make them permanent you'll have to use an init-script. A how-to on that is (currently) out of the scope for this post. Have a look/search in the kernel release thread as there are many examples for that there. I'm sure with this post and these examples you can figure it out by yourself
The values in the echo commands are the stock values (from 2.1.1 version) if not noted otherwise

I will try to keep this post up to date with any relevant changes in the kernel.
Example GPU/CPU undervolting and underclocking scripts by kwerdenker please just use for Reference
Improved version of CPU undervolting script by kwerdenker please just as a reference
P.S.: I will not respond to request what settings you should use to achieve the highest score in a benchmark or how you get the most battery life. This is just to gather the information that is already floating out there. What you do with it is up to you
BETA and RC
beta releases will be available when gokhan releases them
Someone asked in another posting about whats the difference between the governors you can choose in Siyah kernel.
Here is an informative article from Github that explains the difference. The governors are from Cyanogen but I beleive it will give you a fair insight in their caracteristics for Siyah also.
https://github.com/CyanogenMod/cm-k...m-2.6.37/Documentation/cpu-freq/governors.txt
There are also a couple more governors you can choose in the latest RC. Maybe others can give some info. about their caracteristics.
Is it normal, that on 2.1 rc3 i cant see how much juice every app consumes???

Corndude How does insanity do its reporting? is it like miui where you can see the app usage in battery usage section like stock's app manager?
Did you get the stats before on the last kernel you use? I am not on insanity but if I cannot answer your query others can.

Did you just install Rc3 without wiping dalvik? Just want to check . I always do a dalvik and cache wipe before I use CWM to apply the kernel update or If I use Odin to apply the kernel I then boot up into CWM recovery and perform a cache and Dalvik afterwards
Nice thread. Can anybody explain/point me to a good guide on cpu schedulers? This kernel allows changing the scheduler, but i don't know which one is the best for my kind of usage: movies-games-browsing, gpu intensive stuff i guess. Thanks.

Any help is appreciated Mat. Ty for your input
No probs mate.. good idea regarding the thread...At least now the Siyah one can stay just kernel related and all the Q&A can be moved here now..Great job
Issue I had with RC2:
-3G not functional, I didn't realize this until a few hours later when I wasn't at home enjoying my network; tested phone signal, was able to make calls, was in a bit of a cellular black hole but others on the same, and other networks, were able to access data easily,
-Restored my APN's from b/u to address 3G connectivity and at this point I lost all signal, no IMEI, phone number, etc... and would get an FC if I attempted to open the dialer, this was back at home where I have no data issues ever,
-Restored a nandroid b/u and all was good; did not try restoring EFS prior to this.
Just curious what the issue might have been; EFS corrupted (seemed to be a step wise loss), other?
And yes, at this point I realize I should learn a lot more before testing betas, etc... it's on my list Other than that I was thoroughly impressed with the lulzactive governor.

What rom you using?
I am on RC2 on Miui as far as I am aware I did not think it would interfere with EFS or change modem. Was there any think else that might have cause the EFS corruption or APN changes.

i have this problem whereby UV settings are applied during boot. am using init.d scripts. it sticks for 5-10mins and then it automatically reverts back to stock values. anyone else facing this prob?

I'm on DlevROM (XXKI4 based); Siyah 2.0 does back up EFS, so there must be a chance for corruption somewhere along the line.

[B]Fix for usb storage to pc (if not working for some reason,
for example on jellysandwich)[/B]
- Connect usb cable
- Disable/stop HDMI in settings->app->all
- Disconnect
- settings -> xperia -> usb con ->Disable companion message
- settings -> xperia -> usb con ->Switch to the usb mode
which is not set (dont remember if it was msc or mtp)
- Connect
- Disconnect
- Switch to MTP mode
- Connect
- Disconnect
- Switch to MSC mode
- Then it worked for me for some reason..
If its not working just switch a couple of times between mtp and msc
and reconnect cable couple of times
In the end it shoulld be working in MSC mode.
[B]Only for V0.1[/B]
- If wifi is not working:
- Backup original modules (rename /system/lib/modules
to /system/lib/modulesbak)
- Flash updatewifi-signed.zip via recovery OR
- Push the contents of the

About me
I´m a new developer for the Ray. I come from the LG gt540, for which I created TWRP ports (only touch recovery for the device).
I have now created a kernel based on the 4.1.B.0.587 sources by Sony.
It´s called:
FlyKernel
Its purpose:
- Smoothest experience possible
- Stay as close to stock as possible
- Only the most useful governors, io scheds and tweaks will be included
- Let the users have input on features
- But most important of all: Let the Ray Fly.
At the moment its very smooth and gets around 4000 in antutu (smartassv2 1,4ghz).
Let me know what you guys want in the kernel, which governers, which IO schedulers etc. I want to keep it as minimal as possible.

Im focusing on this kernel first. Ive only tested it with stock 587.
Probably gonna release an update today.

you can add wifi modules in kernel. check my git, there's kernel ramdisk that can load modules on boot. just put your modules in right folder.

Hi!
Is this kernel support the two way call recording?
run this one (and updated wifi module) with jj 3.3 and a lot of minor mod, still fine until now.
Pretty fine kernel. I will donate when I get my payment via paypal
PS: the flykernel text in boot too slim, a bit hard to read to me.

@neXus PRIME
Thanks for your great effort.
Here is my findings :
Features:
1. HTC Write protection disabled.
This works great Removed both wp_mod2.ko & init.d script to load it... I can confirm the HTC write protection now disabled.
Updating busybox with no problem
2. Enabled swap support. (if you make a swap partition, it should get used. But need testers)
I don't need this feature, so I don't test it.
3. Default scheduler "noop" (I've always liked noop better then all others)
"noop" as default is shown in the attached screenshot
4. HTC perflock disabled (SetCPU does some magic when perf lock is disabled. Test n report)
No idea how to test this
5. Default Min set to 245 Mhz (My liking)
I like 245 Mhz too but I don't see it in both No Frill and CPU Spy (see attached screenshot)
6. Enable KSM support
Don't really need it but will test later with my old KSM init.d script
7. Default governor "ondemand" (later you can select whatever you like e.g
smartassv2)
"ondemand" is shown as default.
8. Ext2/ext3 file system support. (testers needed)
Don't need this so I do not test
9. Aren't above enough ???
Well... it's enough for now... maybe later s2w feature ? Maybe you can contact maxwen (One V kernel dev) for assistance.
I maybe wrong but I see that the init.d support is not enabled in your kernel. All the above test I ran it with my own ramdisk.

The default min freq is 245 but.... i forgot to modify CPU freq tables so once you try to move the slider, the 245 Mhz freq is lost. And also, smartassv2 somehow becomes default. Maybe i'll fix, maybe not. Coz atis is already hard at CM work, so thought maybe ppl could test the ksm/ext2/3/swap features.

If you used my sources for smartass it becames default because i add it as a default governor. You can modify it in the config. Just use "make menuconfig" and set the default things what you would like. (but first load the original config). Your new modified configuration will saved to "kerneldir/.config"
Just cause I saw your post in the atis's thread, I thought I'd check this out. I have a suggestion for you, instead of using swap, try zram. zram uses part of ram as a compressed swap device. You can get about a 3 to 1 compression ratio and it's much, much faster than swap on a disk. It can be enabled in menuconfig under drivers/staging/zram. Download any of my kernels (in my signature) if you need an example of an init script to start zram.
And, once more, added to Index.
Keep up the good work.
Re: [Kernel/modded] neXusKERNEL v1.0
Who has atis112 kernel can flash this other kernel safely ?
It should work right ?

The default min freq is 245 but.... i forgot to modify CPU freq tables so once you try to move the slider, the 245 Mhz freq is lost. And also, smartassv2 somehow becomes default. Maybe i'll fix, maybe not. Coz atis is already hard at CM work, so thought maybe ppl could test the ksm/ext2/3/swap features.

Maybe a fix to 245 Mhz is great. The governor not necessary to fix as user can choose what they prefer.
Tested the KMS support... it runs great. With KMS enabled, I have more free RAM available at anytime with no performance decrease.
Anyone want to try, you need init.d script with below command
Code:
echo "1" > /sys/kernel/mm/ksm/run
Or just flash attached kms script that I'm using
Good job neXus PRIME :good:

Linked your KSM script post to OP. Plus, im doing the 245 Mhz fix right now.

Updated. Changelog in OP.
@neXus PRIME
Here my finding so far:
Version 2:
1. Freq Table fixed, (Min 122, then 245 just after it)
:good::good:
2. ZRAM support added. (Testers needed)
With zram support added but not enable at default, I find that my ROM lags a lot.
Code:
C:\Users\ckpv5\Desktop\fastboot>adb shell
[email protected]:/ # busybox free
busybox free
total used free shared buffers
Mem: 620984 521988 98996 0 13236
-/+ buffers: 508752 112232
Swap: 0 0 0
[email protected]:/ #
with zram enabled, there is no lag but the smoothness/performance is less compare to v1. Maybe this is due to minfree is default value and cannot be changed with init.d script, will test with lower minfree (as suggested by flar2 in his thread) thru ramdisk change later.
Anyway.. maybe it's my own wrong doing; maybe other user with other ROM can have better result.
Code:
C:\Users\ckpv5\Desktop\fastboot>adb shell
[email protected]:/ # busybox free
busybox free
total used free shared buffers
Mem: 620984 523556 97428 0 13576

Hi,
I'm not making a thread in dev section as i'm not gonna maintain this over time. I just added a few things in atis's config and modified some others to my own liking.
DOWNLOAD:
V2: http://d-h.st/HcS
OLD VERSION: V1: http://d-h.st/dOq
NOTE: Flash zip in below post to enable KSM
http://forum.xda-developers.com/showpost.php?p=38569436&postcount=8
NOTE: Use this excellent app for enabling and verify init.d support
http://forum.xda-developers.com/showthread.php?t=1933849
Features:
Version 2:
1. Freq Table fixed, (Min 122, then 245 just after it)
2. ZRAM support added. (Testers needed)
Version 1
1. HTC Write protection disabled.
2. Enabled swap support. (if you make a swap partition, it should get used. But need testers)
3. Default scheduler "noop" (I've always liked noop better then all others)
4. HTC perflock disabled (SetCPU does some magic when perf lock is disabled. Test n report)
5. Default Min set to 245 Mhz (My liking)
6. Enable KSM support
7. Default governor "ondemand" (later you can select whatever you like e.g smartassv2)
8. Ext2/ext3 file system support. (testers needed)
9. Aren't above enough ???
Guys, atis had a huge role in teaching me how this all works, so major credits to him. The sources are available on my git as well so all are free to fork and try out their own combo of settings.
I'll need a few reports about above features.
Just download n enjoy !!!

neXus PRIME, can you tell me what do you mean with "4. HTC perflock disabled (SetCPU does some magic when perf lock is disabled. Test n report)"? I mean, I have flashed your kernel and I have SetCPU installed but I don't know what is that "magic". Also, if you want, I can test or see what does happen with it enabled (so far, I see no issues).
I have selected: min 122, max 1008, smartassV2, sio.
Thank you very much!

I don't know what setcpu does that's why I called it magic.
Btw, I heard v2 is laggy, so v3 won't have zram enabled.

Ok then! I've found laggy my phone (1.18 deodexed ROM) while it's starting, may be more than with atis's kernel but other than that, I find it great.
Also, may I ask you which are the settings you'd recommend me to set?
Thank you very much!
EDIT: About SetCPU, according to the author through the app, Perflock disabler must be activated in the app if you have a kernel that prevent SetCPU from setting frequencies correctly (stock kernel for example). BUT with neXus PRIME kernel that has perflock disabled, you won't have a single issue using it and you don't need to set on boot Perflock disabler.

Thanks for the feedback
The pegasusq governor will drain more battery then the stock kernel now.. I have to optimize it.
You can set smartassv2 with setcpu/antutu cpu master, it will save battery.

yes i have changed it to smartass v2 ..i didnt get kernel panic ..i hop you continue to add some more features ..and what does this means "/storage/external_SD/Android/data" will be mounted in "/storage/sdcard0/Android/data" at boot time.
"/storage/external_SD/Android/obb" will be mounted in "/storage/sdcard0/Android/obb" at boot time.
Where are sources?

Thank you for your developpement
Would it be possible to incorporate on your kernel a patch for 2WCR support (2 Ways Call Recording) ?
This don't work for me.

You're right... I'm fixing it in the next version. You can mount that directories with this command (terminal emulator):

I will try to add 2WCR.
Yeah, 51.1 fps in Epic Citadel benchmark. On stock gpu there was 44 fps, so the oc works.
Thank you for fast reply, great work and keep doing.
Can you readd the 1300 step?

thanks finaly a kernel for stock rom that what we need^^
i will wait till it's some sort of stable thing, i have the time, hope you will keep updatinh the kernel etc
thanks to the dev for this work.
i will flast, test and report, but the downloadlink is broken for me?!?
What is the different of battery between this kernel and the stock kernel? Will it still draining the battery while using WiFi like stock kernel?!Can anyone post the battery stats screenshot with this kernel?!, I am quite interested in this kernel, I will try it later. BTW thx for your developing
