About
Synapse is a kernel tweaking app developed by @AndreiLux that needs the Universal Kernel Manager (UKM) to work and it's developed by @apb_axel. It is one of the most complete choice for kernel management and it lets you fully unleash your kernel power, may it be battery saving, pure performance or a compromise between the two. You can find more information on UKM at this link: UKM xda thread
Screenshots:
What you need to download:
- Synapse
- UKM for Oneplus Two
- Busybox (i recommend this one) [N.B.: Busybox is not strictly required since there is an in-built busybox in UKM, but installing this updated one in my system has usually resolved stability issues with synapse]
- Root is required (use either SU 2.67 or later or in-built cm13 root)
Useful downloads:
View attachment Synapse.zip - flashable synapse that will install the app in /system
UKM uninstaller from official page
Useful links:
Official synapse/ukm thread
Official synapse google+
Instructions:
1. Download UKM from above link
2. Boot into recovery
3. Flash UKM
4. Reboot to system (no dalvik cache wiping required, but you can do it if you prefer)
5. Uninstall any kernel tweaking apps you might have (Kernel Adiutor, Ex Kernel Manager, Aero Kernel Control.....)
6. Install Busybox, open it and install busybox in system
7. Install Synapse
8. Launch Synapse
9. If you get "no UCI support detected" or synapse is not recognizing phone, just force close the app and re open or reboot the phone and you are good to go
10. Happy tweaking!

Protip:
If you want to be able to change cpu governors/frequencies you have to leave atleast one big core online in the hotplug section; once you have tweaked governors/frequencies, you can turn it off and restart synapse. You will have "Ssekbar error" but that's only because in MM/CM13 the phone is able to shut down all the big cores and if that happens the kernel tweaking apps are not able to change cpu values.
THANKS TO:
@AndreiLux for Synapse
@yarpiin for putting ukm together on opt
@ak for helping @yarpiin in his work
@apb_axel for starting UKM project
@benschhold for providing a good and stable custom kernel (actually the first working one for CM13)
@yarpiin again for his good kernel for cm13!
CONFIRMED TO WORK ON CM13/HOS, NOT TESTED YET ON OOS BUT SHOULD WORK, FEEL FREE TO TEST AND REPORT​
Disclaimer:
I am in no way responsible for any harm, damage, nuclear fission, universal big bang or you getting fired becaus alarm app didn't work that may occur to your device through the use of this app.

LIST OF CUSTOM KERNELS FOR OUR AMAZING ONEPLUS TWO
Kernels with built-in UKM (CM13):
Yarpiin Custom Kernel
Kernels without built-in UKM (CM13):
Benschhold cm13 kernel
N.B.: i'm putting in kernels still mantained and updated by developers and for latest versions of android only (MM); for anyone of you missing Boeffla kernel, i will include as soon as he develops new kernel for OOS 3 and cm13

---

Just in case

Just installed this. Upon installing busybox to system, and installing synapse.. Synapse did not recognize.. Restarted phone and then Synapse can be used.
Add in instructions: reboot phone after installing busybox to system
update: working great otherwise Now support for lower max cpu frequencies, only the input boost frequency. Hopefully kernel and synapse will support this ability

---

Is it possible to make it compatible with boeffla kernel on OOS??

It has been tested for cm13 only, but you can try it on oos with boeffla kernel and report if you had success

I think it should work but might be buggy and also in Andis kernel there is more features than in CM 13 kernel im on CM 13 but will try to set OOS and see what can be done still as advised on Boeffla kernel Andis app is best to control his kernel

---

Awesome can confirm this is working on kingmercians hydrogen mm ROM with the stock kernel. Thanks. Also to the other users using boeffla there is no point in using boeffla and this its actually a bad idea just pick one

no, just swipe synapse away from recents and reload it, it'll work.

Just to clarify there is builded in busybox into UKM and it use its own path , Ukm and synapse works regardless of busybox installed or not and regardless of busybox version installed

And one more thing you have to be either on stock su provided by rom developer or latest supersu 2.67 older versions of su breaking UKM and make device unsupported error in synapse

I'll add in OP

Awesome work bro. I just love to use synapse for control kernel.
thanx .

As I mentioned on the BlissMallow thread, I had some problems getting UKM and Synapse to work properly with the latest ROM/Kernel (02-18/0.3).
Apparently this should work though, so I might have to give it another try.

It is same zip what was your problem ?

Testing here with H2o skydragon, work perfect, great job

I'm unable to change the cpu governor ever since doing this.. I go back into kernel auditor and it doesnt even let me change the governor. Just shows a white box.
My phone will not go into deep sleep, whereas before it would

I figured it was the same zip, so I've gone ahead and used the one I downloaded earlier.
I went through the same procedure as last time, apart from not clearing cache this time around.
This time it actually worked out!
I had to give the big cluster some time to cool down before I could tweak it, but this was the issue with AK's Kernel as well.
As to what went wrong the last time(s); I have no idea.
Thank you for bringing proper kernel management to CM13!

---

Happy that it worked
If i helped just it thanx

Using two kernel management apps simultaneously is a recipe for possible disaster.
Flash UKM and install Synapse. Then uninstall or disable Kernel Adiutor.
Reboot and (possibly) rejoice.

Temp is not the issue but hotplug in cm13 all cores are hotplugged it means cpu 0 and 4 can be setted to offline and that make synapse to not pick up values from these two (they control scaling, govs and others).
Thats why ukm on boot triggers all 4cores online and they stay online until you change values in hotplug tab
