Flash it via Odin (tar) or over CWM (zip) ..
Back to stock flash the rom .. Or wipe in CWM (but i'm not sure about this in CWM)

kernel is the heart of operating system, I am not sure what it consist, but I am sure it has inside an interface to hardware, so OS can communicate with it, for example in kernel you can define and what speed cpu can work and on what voltage, I guess there are also audio, video and camera drivers

Flash stock kernel without Rom?

Is it possible for me just to flash stock kernel instead of the whole stock Rom ? If so is it available here ?

extract the boot.img from a stock rom and flash it via the terminal emulator app or via fastboot. theres always the chance that the stock kernel wont run on whatever rom that youre using. if so, just reflash the rom.
I've got a link to a stock kernel somewhere, which you can flash via cwm recovery. I'll see if i can dig it up.

Wrong section!
Please search for the correct kernel. There are many available for all roms.
As i know their are two custom kernels one by Metallice for cm9 and one by Johnsel for cm10 (no for stock roms)

If anyone knows how to build a kernel, I have source on Github for one for CM10 that you're free to use/fork/whatever. Not sure how it compares to what's out there now, but it works for what I need
there are no custom kernel for stock ROM with OC?

Kernal for Samsung Galaxy Tab 2 GT-P3100
NOTE:
DEVICE USED:Samsung Galaxy Tab 2 GT-P3100
CUSTOM ROM RUNNING: CM 12 UNOFFICIAL GT-P3100 ANDROID 5.0.2 LOLLIPOP
Hi guys.......i'm searching for a kernel for my device which is "Samsung Galaxy Tab 2 GT-P3100"
I tried to flash Dhollmen Kernel but my device got into "RECOVERY LOOP"
NOTE: A recovery loop is a loop where your device keeps booting to recovery mode.
I removed the custom recovery(TWRP) from my device by flashing a zip file.The device turned off
when i tried to turn it on it refused to turn on.......it showed the SAMSUNG LOGO and turned of.....
I flashed TWRP recovery mode again this time using odin.........
I had a back up which i took previously using TWRP.....i restored the backup.....
my device booted to system and works now.....kinda lags now than before but its fine.....
So i guess i need another kernel
the reason i need the kernal is because i want to expand my ram using ram expander but my current kernel doesnt support ram expansion........
somebody pls help me with info about any kernal for my device which supports ram expansion
Thanks in advance

[Solved][Closed] Ram related problem.

After flashing kernel 3.0.x stable release over CM10 beta 3, as sakindia said 10 mb ram will be reduce so total RAM was 408mb. But afterwards when i flash stock rom i still have only 408mb of ram rather than getting 418mb of ram. I have done clean installation of stock ROM. So my question is is it possible to get my orignal rom back?
by "original rom", you mean the stock rom with stock kernel ?

Yes. I have flashed stock rom with stock kernel.

Most probably because kernel 3 configured only 408mb ram & stock kernel can't override it, because api level of kernel 3 is higher than stock kernel. Hence, maybe the higher precedence is the reason.
If this is actually the case, then you will need to format your ram disk then flash stock kernel to get 418mb ram.

Ok.. thanx buddy.. could u help me with that ramdisk stuff. How to restore it it original. And also i hv one problem that i had install stock rom from our pico devlopment site and getting restart often. And afterwards stuck at HTC logo. So is it possible it is caused by this kernel problem or internal stock rom problem?
FYI i hv installed asian stock rom from our stock rom thread.
Again thank you.

You need to unpack & repack (modify, if you want) the ramdisk.img from the kernel source. You can find tutorials via Google or in xda-forums. That's how you can format ramdisk.
If you don't want to get into all this trouble, then simply wipe data / factory reset, wipe cache & wipe dalvik-cache. Then flash kernel & rom again.
This process may also solve your abnormal rebooting issue, also.

Solved..!!
Thanks buddy for your help. I always do clean installation of rom using TWR but i guess i had some problem with it. Installed clockworkmod recovery and flash ROM and get back the 418mb of RAM and also random reboot also solved.
Keep doing your work. Thanx again.

I don't know why i don't like ThunderZap kernel. On my first experience, my phone got freeze and then reboot itself. Until now, i am still using extended stock kernel v2 by rachit rawat but i didn't get CWM
Well i am also frightened to flash kernals which overlock my mobile , i dont want kernals that overlock my mobile ! You will have to wait sometime because roms are not present for xperia L so there is also less support cwm kinda things !

No Kernel development for N8000 - Why ?

Hello XDA community,
i have a short question : Why is the no Kernel development for our N8000 ?
There are brilliant Kernels for the N8010, but none for our device,
I wanted to start collecting donations for the N8000 Kernel- development ( Boeffla Kernel with GPU Control) but there were no responds.
B-Tight
Xcstacy kernel is under development again. And he's trying to merge GPU control, still has issues, but stay tuned.

I would like to get great kernels for my device. I have tested the latest. Xcstacy kernel but the performance of it is very bad for me the stock kernel was better.
Try boeffla. It is for n80xx
