Can anyone explain what flashing kernal does? I've been around Android for while, I know how to root, custom rom but I never really understood what flashing a kernal did, any help would be greatly appreciated.

The kernel is like a bridge for how programs can utilize hardware (ie; CPU/memory/etc). Anytime a program needs to complete a task, the kernel handles how to utilize the hardware for that task. Read this for a more in depth explanation.....

U can undervolt, overclock, underclock, change governor, make sound louder, change screen colors all these u can do with kernel.
What's a kernal. I've heard of kernel but what's a kernal. Does improve battery life ?

When software needs the hardware to do anything, it sends a request to the kernel. Yes it can improve battery life.

No prob. Take in mind that custom kernels can handle tasks differently and may be better on battery life. Just depends on how its coded. If you flash a custom kernel make sure to do a backup of your current ROM beforehand so you can revert back if you don't like custom kernel. Happy flashing!

Okay, I understand that the bootloader is locked and what not and that means no over clocking but I have downloaded a app (dx/d2 overclocking) from the market to allow overclocking and have seen it on the forums here on how to manually. Does this mean we have custom kernels running or just that we have achieved a bypass to overclock. One would think this means they have hacked the boot loader and we are now running custom kernals but im kinda a noob so some more info on the topic would be greatly appreciated. And also, what is cyaogen (sp?)..I see it everywhere and have yet to get it due to not having custom kernels but I still don't know what it is. Thanks

Currently the method of overclocking is done through scripts. Cyanogen is a developer and usually people refer to his ROMs that he creates as Cyanogen as well.

This is not a custom kernel. The word of some great minds is that a kernel has been developed and is still being worked upon but they have been able to get it working at least. There are still some bug issues with it such as the cell radio not working. Until they can find out things like that we wont have the custom kernel.

So I am very new here and I just managed to get a kernel to work after 2 days of hard effort lol. I am using Fraco Kernel on my Nexus 4. I tried two other kernels which are the Trinity and Matr1x kernels and when I load either of those the screen is "shakey" whenever I swipe through the pages or drawer pages and it just doesn't feel right. Please help? I delete the dalvik and cache each time I load a new rom. Any help much appreciated!
Also, for the best balance of battery saving and performance which is the best kernel? I want to UV as well to reduce heat and increase battery life slightly. And what is the best looking kernel?

are you flashing jss/jls kernels on a jwr rom? i bet you are. what rom are you running? you can go into developer options and disable hardware ovetlay, this should "fix" it. theres also a flasablefloating around the threads here that will fix your issue, so you dont have to keep disabling hardware overlays after rebooting.
and there is no best kernel. every device reacts differemtly to every kernel. whats best for me coukd be worst for you. thats why we tell people that you have to try different kernels, to find the bbest kernel for your device and your needs. its actually not even allowed to post whats the best kernel threads on xda. as every person believes that the kernel that they are running is the best, and eventually starts arguments.

The under volt is likely causing the freezing. If you're using JSS, then it has deadlocks that cause temporary freezes. Some kernels have deadlock patches like Neo kernel & Bcm W4.

Jss/Jls and jwr are versions of 4.3 android. The jss freezes are fixable, but the patches aren't in all Roms or kernels.

Recent GPU updates to CM prevent it from being compatible with most kernels. Supersu is flashed via recovery just like the ROM, and I haven't heard of the color issue before. Use stock cm kernel if you wanna use CM.
