[Development Stable][Kernel Adiutor-Mod][V15 - 26JUN2016] A modified Kernel Adiutor (Kernel Tweaking App)

This project has been deprecated. New development is happening at KA-Mod Reborn.

*** Disclamer ***
This app is intended to provide an interface to tweak the features of your kernel.
In no way is my offering of this app an invitation for you to ask me what the various 
features included in your kernel do, or what settings are "best". 
Ask your favorite kernel dev. Preferably by PM, repeatedly. They love that ;)

This thread will be the home of my Kernel Adiutor-Mod. This project was previously known as "Singularity Kernel Adiutor". However, when that kernel project shut down I decided it was time to unbrand this app and birth it into a stand-alone project. Especially given the number of people on various devices who have began using it.

Note: This was original started for a Nexus 6 Kernel. I attempted to post it to the Apps Subforum there. It appears to have ended up in the general apps form. If something doesn't work correctly on your device, please let me know.

Installation instructions

This app has had it's installtion directory, app name, and package name change from the Original Kernel Adiutor.
This was not done in an attempt to disguise it as it's own app. It was intended to prevent conflicts if you choose to keep Grarak's Kernel Adiutor installed.


Current Build

Previous Builds
As of V4, these will no longer be available on AndroidFileHost, they have moved to Github to facilitate direct downloads for in-app updates.

Q. Will you explain what (insest awesome shiny kernel feature) does?
A. No, ask your kernel Dev.

Q. What settings are best for my kernel?
A. I don't know, I probably don't even run the same kernel as you do.

Q. What settings give the best battery life?
A. I don't know. I probably don't even run the same kernel as you do.

Q. What kernel do you run?
A. Does it really matter? It doesn't have anything to do with the app.

Q. Can I post my benchmark/battery screenshots on (insert super awesome kernel with tweaked settings) in the thread?
A. No. Benchmarks, and battery screenshots are thread garbage and should really have some sort of auto-deletion. Don't post them.... anywhere, ever, for the love of god.

Q. I found a bug, what do I do?
A. Provide as much information as possible and post in the thread. What feature? What didn't work? Can you provide screenshots to show how it's not working? Maybe provide a logcat, if the app is crashing. If you know the sysfs paths and expected values, those always help.

Q. Something that worked in the original Kernel Adiutor is broken here... Why?
A. I've modified/added quite a bit of code, it's not impossible that I broke something along the way even though it worked for me. Please provide whatever information you can (see previous FAQ item) so I can try to fix it.

Q. I was using this when it was known as Singularity Kernel Adiutor (SKA), what's the easiest way to switch?
A. I apologize, but you will have to reconfigure things when you make the switch (and uninstall SKA). I tried to figure out some way to move the app data over, but decided it wasn't worth the time. You can probably move profiles over from the old directory /data/data/com.singularity.kerneladiutor to /data/data/com.kerneladiutor.mod
Unfortunately, I won't help with this process. It'll either work or it wont.

Information for Devs/Advanced users

Kernel Download Support
I have modified this unbranded release so that Kernel Devs can add support (and override whatever is included in the app already) for their kernel's downloads by including /res/kernel_adiutor_mod/downloads.json in their ramdisk.

Why? Well... It removes the need for commits to add support for the kernels within the app. Want support? Add the file to the ramdisk. Next time that a user flashes the kernel, the app will display them with your downloads.

Information taken from Grarak's Wiki
The original app required the files to either be downloads.json to be compiled into the app, or in the app's data directory. I simply added the /res directory and made the priority /res > data dir > app's resources. So the information is the same.

This file is static, once configured and added to the ramdisk it will remain valid unless you remove/move the link file. It will pull this file each time the dowloads section is opened, pulling in whatever changes you've made to the linked file.

For an example of the downloads link, check any of the ones included here as well as the example in Grarak's wiki. This file will be dynamic, any changes that you make to it will actively be pulled when users open the downloads section within the App once the static file has been added to the ramdisk.

How to post a bug:

1) Clearly document steps to reproduce the issue you've encountered

2) Collect logs
Lots of methods to do that

3) Go to and create an issue.
Post the steps from #1 and logs from #2
Answer these questions:
What did you expect to happen?
What actually happened?
What phone/os/rom are you running?
Do you have xposed framework installed?

I know what people are thinking.

"But Yoinx, feature xyz is missing. How can I get it added?"

Well, simple. Provide me with the sysfs path, the expected values/range, a title and description. If you do, I'll see what I can do to add it.

Use the feature request function of devdb and post saying that is the if you like. Don't just post it in the thread, if this thread ends up taking off (probably won't :s) then it'll get buried.

It'll work on anything that kernel Adiutor worked on. This just has additional features.

The reason I mentioned that I had originally built it for nexus 6 is because some sysfs paths may be device specific.

Attached a logcat of the crash. Mind checking it out? Would definitely love to give this mod a try.
