flashing from recovery will not install the kernel ever. You have to flash the kernel from pc, then rom from recovery.
if using a kernel NOT given by default with the ROM it will likely need repacking and you would additionally have to flash the appropriate modules

[Q] How do I get stock kernel back?

How can I get my stock kernel back? Or does flashing a ROM change the kernel? I don't really understand kernels yet in terms of compatibility, and such. I just don't want to brick my phone, so I'm making sure I do it right.

Roms usually involve a kernel already built in, check the OP description.
For example if you are on cm10 and flash the ktoonsez aosp kernel, then later flash a nightlie build, the kernel will be overwritten with the one built in cm10. You have to reflash the ktoonsez again afterwards if you want to use it.
So if you want stock kernel, flash a stock ROM with built in stock kernel.

Make sure the kernel you flash is sourced from the same source as your ROM, ie any TouchWiz LG8 ROM needs to have an LG8-sourced kernel - custom or stock.

Custom kernels ...are they necessary ? what do they do ?

hi all !
i just flashed cm 10.1 official and it is great so far except for the superuser issue
so i tried to flash a franco kernel as i always do , franco r325 and all my phone went dead force crashing everywhere , without panicking i formatted my phone and i downloaded the r345 kernel but it seems to be an img file something cwm can't flash so i decided to try trinity kernel but i am not sure which is made for 4.2 so i am not taking the risk of flashing a random one then it struck me ...why do i even need to flash kernels anyway? isn't stock kenel the same? so can someone enlightnen me?

Custom kernels allows you to overclock and undervolt the CPU and GPU.
Some custom kernels also add extra features that a stock kernel does not have; fast charge mod, kernel sound mod etc.

kernels control pretty much every aspect of your device. they connect your cpu to your os and hardware. custom kernels add functuality that isnt included with the stock kernel, as well as performance and battery enhancements. google the the word kernel or linux kernel for more info.
now about your issue.. cm made some modifications that made many custom kernels non bootable on cm. franco kernel in the img format isnt flashable via recovery but is flashable via fastboot or the franco kernel app. trinity kernels latest 4.2.1 kernel is alpha10, but the 4.1.2 kernels also run on 4.2.1.

first you need a custom kernel then you can overclock grand and i dont think there is a kernel which supports overclocking as you can only overclock grand only in custom roms like cm or other roms

nah overclocking can be done in both custom and stock ROMs you just need a kernel based on CM or based on stock 4.1.2 or 4.2.2
There is one custom kernel available for our grand based on 4.1.2 stock but it is very old and out of development.
So yea, right now overclocking is out of the question for us till we have a better kernel
EDIT :
This is a 4.1.2 based kernel but like I said it wasn't finished and is currently out of development

The kernel is included in the ROM. There is no need to flash any other kernel to get it working, but the kernel has some battery drains. Hence You can flash evolve 1.25 kernel after flashing the ROM. Link to kernel.
