You cannot uninstall a kernel. Your phone will not work without one. All you can do is replace a kernel with another.

Usually you can just flash one over the other but some kernels add scripts and change things in /system so in that case you must reflash the rom first. Read each thread of the kernel you are leaving behind. If there are no instructions, assume its a simple flash (kernel) to replace job. Always check /system/etc/init.d for kernel script and delete them first

Edit added (kernel) to avoid confusion
[Nexus 5 Original Android Development] choosetobelieve:
By using franco kernek, there is a backup and restore function to restore the stock kernel then I uninstalled franco kernel app. Finally i installed this kernel.

I am using stock rom, how to reflash?
[Nexus 5 Original Android Development] danarama:
If you don't know how to flash a kernel, you're not ready to be changing kernels. Perhaps you should familiarise yourself with the thread stuck at the top of the q&a forum. This is a development thread. We should not use it to learn the basics when there is a thread dedicated to the basics already
[Nexus 5 Original Android Development] choosetobelieve:
I have purchased the franco kernel from google player store. My logical us that restore the stock kernel then refresh another way.

I thought I saw flar recommend flashing Rom first, was that before he implemented stock ramdisk option in installer? I've been following this thread for awhile so I suppose it just all mixes together, haha.
[Nexus 5 Original Android Development] notbrodie:
not possible atm
[Nexus 5 Original Android Development] paradoxiumwind:
Ok, for the record, I'm running 0.29 on Carbon (AOSP based I believe) ROM fine now without any issues - I *think* it may be causing a volume issue, where when I am using earphones, the media volume doesn't work at all for it, but I don't know if that's the ROM or the kernel. Other than that no problems.
[Nexus 5 Original Android Development] letmedanz:
That's right.

it is still recommended to flash stock rom first just to ensure you don't run into funny problems & start blaming the sun, stars & the dev :p

but flar has made it so that it can be used without stock being flashed first
[Nexus 5 Original Android Development] drawde40599:
Im sure u no 29 is for CM based Roms so if your running on a AOSP ROM there's really no point in mentioning here with issues . I would find out exactly what your ROM is ( cm or aosp) and use appropriate kernel build . if its cm based then u should run the rom 100% stock and see if issue is still there without this kernel ,and if its aosp then install build 26
[Nexus 5 Original Android Development] danarama:
26 aosp

27 aosp with cm audio (you!)

28 full cm

29 full cm

which lower brightness module are you using in elementals? bricked or aragagi? i'm asking because I can't seem to make lux use the lower brightness steps. the only way I can get to them is my disabling lux and manually adjusting my brightness to the lowered levels.

is anyone else here experiencing a similar problem? does lux go all the way down to one for everyone else?

Carbon ROM is AOSP ROM. So the 0.26 Kernel is the best for AOSP ROM ;)

Here's a little init.d script to change to Interactive governor and undervolt. Interactive is a bit smoother in my opinion, although possibly not as battery friendly.

It doesn't interfere with the 99elementalx if it's called something like 99userconfig. Keep in mind, the voltage settings might not work for everyone.

is there any chance you'd try out a version using showp's brightness scale? instead of going completely dark at 1, then bright at 2, showp's module has a few steps in between, allowing for a more dynamic display.

Yeah, I overlooked it in the Aroma installer. Having a problem though with newer roms on .29 CM, it's causing the rom to not be able to lower the volume. Stays on max volume no matter what. I tried it on Carbon's latest nightly, same with Mahdi's and Liquids latest builds.

[Nexus 5 Original Android Development] t1.8matt:
Worked perfectly.
[Nexus 5 Original Android Development] :
some stuff like max screen off frequency 1190MHz (optional) is not optional in aroma, it is already ticked (although we can disable it),

should we assume that the ones already ticked is the best option to choose?

does the max screen off frequency 1190MHz saves battery and reduces performance or it consumes more battery but has a faster wake up? (in other words, what is the default max screen off frequency? 2200MHz?)

why didnt you put the ScreenDimmer mod ticked as default? I've installed it and it reduces battery consumption so much and more if you usually are in dark places which 0% is just too bright and its a waste of battery (does it has any disadvantages?)
[Nexus 5 Original Android Development] flar2:
Defaults are best

I've fixed up the screen dimmer for the next release, which might be this week. Still testing some things.

I'm also thinking about changing default sched to deadline. What do you all think?
[Nexus 5 Original Android Development] danarama:
No issues with it myself. I just change it if I want anyway :)

I can never settle on one scheduler to the next. I usually end up on FIOPS.
[Nexus 5 Original Android Development] Syk69:
I think deadline is good in high io activity situation. Where some users have lots of things going on in the background they might experience scrolling lag with other io schedulers. Not much difference between all of them in regular use.
[Nexus 5 Original Android Development] JmPTaz09:
I've known plenty of good kernel devs who tend to prefer deadline, lol, so it should work well :). I typically don't notice much in daily use between the various schedulers as well...
[Nexus 5 Original Android Development] drawde40599:
I no if I use row for few weeks then switch to deadline I always think deadline is better till I switch back to row , I can't tell what's better with your kernel there really almost the same
[Nexus 5 Original Android Development] :
oh it currently doesnt work alright? it goes from 0% directly to -40% or -60% without any steps, I kinda like it since I only put it on at night when im at home and I forget about it ^^

Do you by chance have AdAway installed? There is a known issue when it fails to update the host file triggering the daemonsu process which causes the cpu to be stuck at certain frequency hence eats away the battery life. Solution is to kill the process or restart the phone.

No sir, I don't not have AdAway but thanks for the input. I also posted in the batter Battery stats thread and they suggested stuck CPU States are a kernel issue.

[Nexus 5 Original Android Development] flar2:
Do you have the faux clock app? You can disable those C2 and C3 and see if it helps.

Otherwise, you have to go to /sys/module/pm_8x60/modes/ and go into each of the cpu folders and set the power_collapse idle_enabled and suspend_enabled to 0.

I have noticed any issues with it, but I don't think there's actually much benefit to setting these sleep states. If they are indeed causing a problem, I will not enable them in the next version.
