My nexus 7 is rebooting after a while using trinity kernel. I'm in stock 4.2.1 and I had random reboots even when no it applying any kind of OC just the kernel's default settings! What can I do to prevent that from happening?
Flash a different kernel.
Not all tablets are created equal. Whereas one will play nice with a particular kernel, the very next one off the assembly line may not.

I flashed motley kernel without any oc and I still get random reboots. Should I go back to stock kernel?

i bet its an app causing it.
Don't know why I initially glanced over you being on 4.2.1. Random reboots are actually a known issue with 4.2.x due to a problem at the OS level. Essentially, anything that uses geolocation can inadvertently trigger a reboot. Apps such as HD Widgets have updated to use a workaround until Google themselves fixes the issue. In the meantime, the only certain way to avoid the reboots is to turn off location services or downgrade to 4.1.2.
Unfortunately, this bug isn't consistently reproducible, but it does affect the entire Nexus line of devices using 4.2 and 4.2.1.

Thanks buddy, with motley kernel I've just had 1 reboot. I'm going to test turning location services off and see what happens. BTW any idea how to oc the GPU in motley kernel? in trickster mod there's no option for it.

is ocing the gpu enabled in motley kernel? it has to be a feature of the kernel to be able to do it, an app cant do it if the kernel doesnt include the mod.

According to the kernels features, it supports GPU oc

the kernel might use a different method than the one the app "knows". for an example, cm color control with trinity kernel on the gnex. both cm and trinity have color control enabled, but since cm uses a different method of color control, you cant use the native cm rom color control option with trinity kernel, nor can you use the trinity kernel toolbox to control color on a cm rom/kernel. as they say, theres more than one way to skin a cat.

honestly i dont, id assume that motley used francos method since thats the most popular way. you should probably ask in the motley thread. but for some reason, i dont think it does, not the 4.2.1 kernel at least. maybe he just didnt update his op to reflext this. ask in the thread anyways
Guys I have a question.
I have stock rom but I'm using custom kernel expecially for UnderVolt.
I want UV not for battery life, that IMHO don't get incresed that much, but for heat reason.
Is it possible to have a stock kernel just with undervolting? Would be that hard to build such a kernel by myself?

No, you cannot undervolt with a stock kernel. If you know how to enable undervolting in a kernel then good job!

Why would you prefer stock kernel vs other custom one? You get better results witth custom
In the Harsh kernel thread he's provided stock kernel with UV several times you can do a search there or ask there, also Harsh kernel itself is modified stock kernel with tons of optimizations, UV etc
Hi there,
Im searching for the CM kernel with the ability to undervolt as a kind of add in it?
Is such a kernel available? Can anyone build such a kernel?
Thx
Cm is just stock kernel. Faux made an enhanced stock kernel with undervolt and gamma control http://faux.androidro.ms/mako/mako-jb-enhanced_stock_422_r2.zip

Re,
Yes, maybe, there is a lot of good feedback
But I don't use it so I can't really comment, I just read the thread. You have, like said above an enhanced stock kernel with undervolt and 2 other features, nothing more. And you have the custom kernel with overclock CPU / GPU, you can change vibration, I/O scheduler, TCP congestion, etc...
Read the OP for more informations and give it a try

i dont think they built in the ability to adjust voltage. but, since its open source, anyone can build tbe kernel from cm source and add the ability to change voltages.

Incorrect. CM barely touches the kernel as is, but the MAKO developer (his name escapes me) is even more conservative than that. It is nearly stock.

give it time
cm kernels come with everything there is and are often highly modified by the end of a device's life cycle
if this dev is conservative, ok, then it might take longer or until some new kid takes over.
just don't say cm barely touches kernels

Wrong! Try Harsh. It's flash it and leave it. Very good kernel. Highly recommended. Supports UV and uses mpdecision.

both trinity and franco kernels are also cleaned up so theres no bloating. trinity is one of the least bloated kernels as it doesnt include any of the normal "buzzword" additions, only what is needed, highly optimized, debugging removed, "bull**** free" as it states in its op.

Faux got enhanced stock kernel not moded alot. Just some unlocks and fixes. Maybe try this one. Im already on enhanced and its stable plus you got gamma unlocked.

Hello,
I use SM-N9005 4.4.2, Baseband ver. N9005XXUENC2, Kernel ver. 3.4.0-1168347, Build number KOT49H.N9005XXUEND5.
It's a rooted, stock ROM somewhat modded with Xposed, Android Tuner app etc.
I'd like to flash a custom Kernel which will allow overclocking, eXtended battery life and some other neat features I hope more experienced XDA community will recomend.
So, what Kernel would you recomend as a mix of stability and performance for my stock TW rom? I am fairly inexperienced in these waters. Are Baseband version, Build number etc important when deciding on a Kernel?
Any advice would be welcome. Thank you in advance.

Try n3 by wootever, sneakykat and leankernel (last doesn't have so many features but is great for battery & performance) and my personal favorite ael kernel of course.
The kernels are pretty easy to flash just put on SD flash and wipe Cache & dalvik. So don't worry if you don't like the kernel just flash another one.
One more thing don't put two different apps for kernel settings (like Synapse & Trickster) on the device cause that may cause conflicts. Have fun testing

Is it really necessary to wipe cache & dalvik? I've read in several posts that it is not required as there will not be any benefit.

To quote Hacre, an excellent dev on other Samsung devices - wiping cache and dalvik for kernel flashing is like filling your car tires when the gearbox is ruined...

Thanks for your response. I've flashed the AEL kernel, recommended by you.
What are the immediate advantages I received compared to the default one? How do I get the most out of it now - what next?
Thanks for your patience.

That is pretty hard to answer cause I do not know what settings you prefer. (Performance, battery or a mix of both). Download Trickster from app store or set cpu (for last you have to pay though). At first I would try to set just governor and I/O scheduler. In the link you will find some information. Got helped not too long ago

No for Benchmark maybe but most of the time the phone will crash then.
Personally I take 22565600 as max and 300 min with intellidemand governor and deadline scheduler but every phone works different that's also why you won't find any "perfect" kernel or governor.
how can I flash the kernel I tried CWM to flash the zip file but it doesn't work please help me to find my solution
Hi guys, fairly new to modding my phone, have tried a few different roms and kernels over the last week, and have sort of settled on cyanogen CM12.1 lolliop 5.1.1. with the kernel that comes with the rom. I've been seeing a few posts/roms that claim its possible to overclock the processor to 2.7ghz now I've tried to install synapse, and stweaks neither of which seem compatible, so I have kernel adiutor installed, but the max frequency it will offer me is 2,3 ghz, am I missing something? can't seem to find any info, can anyone point me in the right direction please

No apps can overclock if the kernel doesn't support the overclock.
Not all phones can can reach so high overclock.
Get arters kernel for cm12.1. Or use cm12.1 by temasek which supports up to 2.5
Thanks for the advise, I'm going to install arters kernel now and see what happens
I installed the arter kernel, and still no overclocking, also reduced my Antutu bench from 45403 down to 3400ish, so gone back to cm12.1 kernel for now. any ideas why I can't increase mas cpu speed?
Maybe it doesn't support till 2.7GHz. Try different kernel

Ok. well I have an update, I flashed the kitkat 4.4 liquid smooth rom yesterday, and that allowed me to overclock the cpu but unfortunatly, even overclocked it was slower than Tamasks cm12.1 rom, I also tried the liquid smooth lollipop rom, but again, it didn't allow me to overclock the cpu, it was faster than the kitkat rom, but still not as fast as the cm12.1 so I've gone back to that for now. Its looking like something to do with the lollipop version of android thats stopping the cpu from being overclocked....
Hm strange
