CPU overclock 1.7 GHz ?

---

I have a question about the boeffla wakelock blocker
Literally can't find any way to use it/an application that isn't malware

---

No, it will create a thermal throttle mess instead of improvement

Yes, I have heard about kernel managers, but I don't like to use them and the ones I used didn't have this option
Which manager is this?

There are many which display these features:-
- Smartpack Kernel manager
- Kernel Auditor
- HkTweaks (Especially made for exynos SoC)
The one which I am personally using is hKtweaks, you can get it on github, actually all kernel managers available are the fork of old kernel auditor.

I appreciate it, thanks for your feedback, make sure you vote

Thanks for your work.
Can you also provide the kernel source with the modifications? I know you used the universal7580 sources from LOS, but what I'm asking for is the fork along with the things you tweaked/added. If you don't mind, that is.
