[Q] Question about Kernels - HD2 Android Q&A, Help & Troubleshooting and Genera

Hi, just a quick question
Kernels come WITH the Rom? right?
...like if I flash a custom rom...no need to worry about the Kernel?
do I need a specific Kernel for a specific rom to run properly?
I've been flashing roms since ages but still dont know a thing about Kernels
thanks

Yes, kernels come with the ROM. If a ROM doesn't have a kernel, it won't boot (hence the name "kernel").
Usually, the most "proper" kernel for your ROM would be the one that came with it. Although sometimes, flashing a different kernel can improve performance/responsiveness/battery ..etc .... But it can also break things if you don't know what you're doing. It's always a good idea to make a backup before doing something.
Have fun.

What do kernels do?

I've been flashing different roms but I don't flash kernels can you guys tell me what flashing one of them will do?

What most use them for is to (overclock) their tabs and other features. Make sure you get the one for the rom you have installed.
Kernels are the simple codes written to utilize the hardware. They make available all the functions of hardware with system calls. Some of the kernels are also called micro kernels as they use very little codes to use all the functions of hardware and are thus very small in size. But coding becomes a little bit typical. Well simply, when you are changing your rom most of the time your kernel also change as different dev's use different kernel for there rom. You need not to worry to change kernel if you dont know much about it. Kernel are also responsible for increasing the speed of your tab as they change the way hardware is implemented.
One very good outcome of changing kernel you must have noted is that of overclocking.
Try to use the kernel which is stable.

[Q] questions before flashing a rom

I have rooted my SGY S5360 and am using the CWM skin thingy(every time u gotta flash it to use cwm-temporary cwm). before flashing a new rom i wish to clarify a few things:
1) can i make a cwm backup of stock rom? if so, how?
2)SGY in different regions of the world have different csc(i think that what it called- like DXKKQ(that was made up, but u know what i mean)
so do i need to worry about this before flashing a rom?
3)do i need to flash kernels after roms for overclocking and stuff?
4)i know best rom threads arent allowed but what im asking for is the name of a good stable rom to start with.
5)what is the whole issue with hyperion 8? can i download it?
i know its a lot but pls bear with me...
thanks!

1)in cwm...go to backup and restore..and choose backup
2)no need to worry about that as long as ur device supported by that custom rom
3)yes..for overclocking u can use merruk kernel but it still unstable
4)i suggest u use hyperion 8 or remix or creed or evo
5)not sure about that
yes....he's right
i suggest u don't overclocking you're cpu..

plz dont use merruk.kernel... bcoz it has a lot of bugs & highly unstable. also overclocking didnt give me any increased perfomance...

[Q] Help with ROM

As you guys may know, I recently downloaded the latest matriz mod by mathkid...do you think I need a ROM installed to use at its full potential? If so, which ROM should I install and do I have to re-install the kernel?
1. U don't have to flash another ROM if you are on stock ROM or another AOSP ROM
2. Feel free to flash any ROM u want all AOSP based Ron's should work with this kernel.
3. If u flash another ROM u have to flash the kernel again because the stock kernel of the ROM will be flashed as well.
BTW. Post this kind of questions into the Q&A forum for the N4.

So I'm on Stock ROM right now. I don't need to redo the installation process and just flash it at will? Didn't know you can flash multiple roms too...
what roms do you guys recommend with the most with matr1x kernel?

matrix is not a rom, it is a kernel. all roms include kernels, or your phone would never work. all you do is flash matrix over what you have now, and itll replace your current kernel with matrix. that is all, do not over think it, do not make it more complicated then it actually is. and no, no one can tell you what rom to run, it is only your personal choice and no one elses. there are roms in the development section, read their threads, then you decide.

I know matrix is a kernel, I'm saying which one would be the most appropriate to go with it. One more question: Whenever there's an android update and I have flashed a Rom and Kernel, do I have to redo the flashing process again? ex. Android 4.4.4

Yo that sounds nice...any other rom+kernel combinations? I might try mahdi with matr1x myself.

Kernel VS Not. Difference?

Good day
Anyone can show the differences between a Kernel ROM and NOT?
I'm currently running on SuperStock-Rom V2.4 and planning to flash SuperStock-Kernel.
Want to know the Advantages and Disadvantages.
Thanks
One is a full ROM with different software and various interface differences, depending on the ROM you choose.
A kernel is the base operator for any OS. This tells your hardware how to work and potentially unlocks features the standard kernel does not allow.
Not sure if this explains them well in non technical terms.

That helps, thanks Man! But from your opinion. Which one is better? Kernel or Not?
Want to know more about difference between the two. Heheh. Much better from DEVs. Hehehe.
Thanks!
I think i had the wrong question here.
I was actually thinking the Kernel is a different ROM that comes with Kernel version.
So Kernel is a add-on to flash on top of a ROM. Right?

Yes. The two are totally separate things. You can be rooted on a stock ROM and use a custom kernel.
Likewise, you carbon be in a custom ROM with a stock kernel.
To ask which is best wouldn't make sense as they are two totally different parts of a phone\OS.

In my case, I'm currently in a custom ROM right now which is SuperStock-Rom V2.4, can I flash the SuperStock-Kernel V2.0.1?
Thanks
depends rom might conflict with kernel since kernel moght set flags the rom woukd freak on. A good kernel can make a stock rom fly. But a stock kernel cant help even the most optimised rom. Kernel is what gives it the horse power.
Just make sure you have a flashable backup of your current kernel so you can revert if you run in to any boot issues, then you should be good to go.

Any need for custom kernel

I'm using stable oos build 5.1.2. Is there any need to use a custom kernel? Does it really help if I use a custom kernel.

Help for what? If you have no problems, don't flash things that you don't need.
There's no general recommendation to use a custom kernel without an intention.
Every kernel has its own advantages over the others(and stock) where you must decide/try if you need it. And custom kernels can have side affects also, be prepared to face some...
