[Q] any way to flash a different rom while keeping your current kernel?

some help would be appreciated! or how can i back up my kernel to update.zip? i tried sgs kernel flasher but it is incompatible

Easiest way I would think is to just flash that kernel again right afterwards. Kernels are generic, so none of your personal data is stored on them.

lets say i dont have it now what?

It's not a kernel that you can download from here..?

sadly no

Look in the Dev then sticky then all in one thread you'll find all the kernel's custom and stock I have all them download from there.

unless that kernel was custom made for u by a Dev then its here. If u or someone u know compiled it u wouldn't be asking the question lol. u can back up the kernel using advanced and then flash back after rom install

BLN

Hi!
Is there a generalist way to get bln on any kernel? My question goes because not everyone and every developer likes to add it. For instance. I have 4.1.1 is there any zip I could always flash over any jb rom?
Thanks.

It depends on the rom. If it has BLN mod or not.

I think BLN must be inplemented in the kernel.
I don´t know any mod for flashing over a ROM that gives you BLN.

Either the rom has to have the BLN feature, or the kernel. If you're on STOCK 4.1.1 then you will need to flash either a kernel or a new rom with the feature. You will need to download the 'NS Tools' app and choose the settings to your liking.
Hope this helps!

Well, I have no idea what kernel meant but I know that kernel control everything inside our phone, from brightness to phone call. Let just say that if our phone doesn't have kernel, probably its dead right now.
The difference of kernel 3.0.X, We don't know yet from the users side, but from the kernel it self, it will fix the most bug our phone has.
For the 3rd, same like above, we don't know yet but I'm sure it work on every CM9/10 ROMs. If you expect kernel 3.0 will work perfectly, nope it still has random crash and battery drain.

1. Kernel is the core of the OS, which mean it let the OS to control the Phone
2. Yes, due to JB rom base on android 4.1 and android 4.1 need kernel 3.x to work full function
So, we need the JB rom work good, we need kernel 3.x, i have a Galaxy W with kernel 3 CM9, it is hell alot faster.
edit, by the way, kernel 3 is not mean to fix the bugs. it is to let the new fuction functioning.

Kernel is actually the software which acts as an intermediate communicator b/w the phone's 'OS n Hardware'.. So possibly we might get from 3.0
full h/w acceleration
Speed imprvmnt
Finally since ics n later version's r based on kernel 3 there might be some performance improvements..
P.s: frm some linux form I came to know that, there is not much diff b/w kernel 2.6.* & 3.0.*... Linux jst change the no. system. From 2.6 they directly jumped to 3.0.. More info google

Kernels, must have a ROM ?

So, do you need a specific ROM for specific kernels? Or can you download kernels without a ROM?

If possible to download kernels, can someone link me to a list of them if that's how it works.

I know I am sounding like a total noob right now, I've flashed ROMs many times but don't know much about kernels

@jongonzalez716705
Of course you can flash a kernel without a rom.
Make sure that the kernel is compatible with your current rom.
Profits about a kernel;
+ Some kernels let your overlock your processors
+ faster boot time
+ some kernels have some other advantages.
Which phone do you have?
Hit the thanks button if you think this post is usefull .

I currently have a Samsung Galaxy S 5 SM-G900T. I'm currently running XtreStolite ROM but currently running through some issues like wallpaper picker keeps force closing when I choose one, Setup for Fingerprint says to restart, I do, and still nothing, and tried downloading MyFiles but when ever I do an action, it force closes.

I know but I've downloaded a ROM before that had its own custom kernel. Had fun overclocking but spent more time underclocking. Is there somewhere where I can download certain kernels?

Yes,you can flash Kernels.
Why are custom kernels android useful?
Ans:Kernels are the brain of your Android device and communicate between software and hardware. Therefore, they are responsible for managing things like CPU / GPU clocking speed, screen sensitivity / colors or voltage. By using a custom kernel you can not only improve battery life, but also increase system performance.
Many custom ROMs already come with their own kernels. This is done to implement software communication of the custom ROM with the hardware of the device and also to ensure a better performance. Nevertheless, you are often also able to flash custom kernels to custom ROMs. If you decided to stick to a rooted version of stock Android, flashing a new kernel can offer you additional performance with the convenience of a stock OS.
Always make sure to check compatibility of the kernel with your ROM and device, because flashing a wrong kernel can brick your phone!
You can use this apk called as Franco.kernel. The app is available in playstore.

Yeah I was wondering this too....
Is it possible to take my original rom kernel (built for mediatek 6582) and use it on say cyanogen ?

About incorrect kernel flashing and camera bug

I have this question about kernel flashing, i tried google but no luck so xda is my last resort, anyway i want to flash a overclocked kernel of another rom, if i do so will it hard brick my device, as i cant try it not until i know that i can boot back into recovery even with incorrect kernel, i really hope someone can answer this. And oh yes i need to ask another question about camera not focusing correctly,i mean it focuses correctly then again becomes blur to take a shot, but when i do video calling in whatsapp, it works kinda ok that what my partner said but idk i have Grand 2 ms013g. Thnx

It is impossible to answer that if we don't know what kernel you're trying to flash and what specific device model number you're trying to flash it on or what ROM you're using(i.e. custom ROM or Stock ROM, if custom ROM, what ROM?)
If the kernel was not made for your device, you can't use it. If it was made for your device, then it is a question of whether the kernel is compatible with the ROM you're using.

Ummm
This is the first time that someone replied to my post on xda i m lucky ig, and thnx a lot for the precious reply, so i have aokp 7.1.2 custom rom, and i think it has stock kernel, i want to flash deds kernel, infected kernel, and some others i need to check, which are compatible with my device but not this rom, it say touchwiz, 5.x, 6.x. and my device is Samsung Grand 2 G7102 with msm8226 i want to install overclock kernel as i m more into gamings even tho i still have some good gaming but not that good those kernel support overclocking upto 1.6ghz, if u need more info i m willing to give it to u.

TouchWIz stuff is stock only, you can't mix TouchWiz stuff with custom ROMs such as AOSP, AOKP, LOS, etc.
Touchwiz can use modified stock kernels that have overclock support built in but you can't use stock kernel or modified stock kernels with custom ROMs.
Likewise, you can't use stock with custom kernels either, stock can only use stock and modified stock kernel.
