How to flash a kernal

Title says it all. How do I flash a kernal like say Franco of ezeekles kernal?
1.Should I have a custom from or can I flash it on the stock one?
2.should I use a custom recovery aka cwm or is it OK if I have the stock one?
3. Finally after downloading the kernal file what is the code on fast boot to pull the original one and the code to push the new one?
Thank you in advance guys .

1. As long as you're unlocked and rooted, you can flash a custom kernel to any rom
2. Yes, flash through cwm revovery, or;
3. Extract the boot.img from the Kernel.zip file you downloaded. Command is "fastboot flash boot boot.img"
If you're not familiar with adb/ fastboot, option 2 is the safest

Another possibility if you want to flash Franco or Lean Kernel is Francos app (franco.Kernel updater) from the market.
With that app you can download and flash the kernel.
Of course you need root for that.

1. You can have any ROM and flash a custom kernel (although some kernels require you have 4.0.3 or higher).
2. You can use CWM and it is recommended that you do. Just place the kernel's .zip somewhere on your SD card and then go into recovery and install from SD card.
3. There is no need to do anything with fastboot as the recovery flashes .zips and does everything. However if you want a back-up the original kernel, you can download the factory images from Google (assuming you have a yakju device or you can swap to yakju if you're not on a CDMA network) and you'll have the copy of the kernel.

Thank you a lot guys .. that was helpful and now I can flash a custom kernal easily

How to revert to stock kernel?

Hi guys,
How do I revert to stock kernel? I'm using Trinity for now.. where can I download the stock kernel to flash?

You can download the factory image for whatever version of Android you're using, extract boot.img from it, and flash it with "fastboot flash boot boot.img". Or if you're using a custom ROM, use the boot.img from that.

Is there any .zip that I can use to flash straight from Clockwork?

Search in the gsm dev section for bigxie's ota jb rom. IIRC look in the 2nd post

There is an app, if your rooted, to unlock the bootloader with out wiping the data. Not sure what you mean by flashing in CMW without USB(?)
:Edit: BootUnlocker

Unlocked bootloader is needed to run a custom kernel. Root is needed to tinker with and make proper use of said kernel unless you wanna run the stock values. And really, what's the fun in that? Since (if I remember correctly) unlocking your boot loader requires a wipe, then no I don't think you can. But considering most of us have probably done fresh installs literally hundreds on times, I can tell you it doesn't take long at all to set your device back up. Just do it.

My Gnex has unlocked and rooted already, so I can just flash without doing any wiping, right?
