is there a way to flash only the kernel and not losing data? and how to do I back up and restore data if I want to unroot? sorry for the noob question. Kinda new to android thanks in advance!

Whatsup OP,
easiest way is mentioned, is to simply reflash the entire stock ROM, perhaps the question you should be asking is how to extract the Kernel from the entire ROM zip?
also i would recomend reflashing the entire stock ROM on anyway just to avoid any issues.
Hope i helped!

Here is a link for the ME2 dated 2-5-2013 stock kernel and recovery http://fs1.d-h.st/download/00046/xDf/I9505XXUAME2-STOCK-KERNEL-RECOVERY.rar. Extract once with 7-zip and flash the md5 file in PDA with Odin.

Is it okay to flash ME2 kernel even if I have MDK?

If you already rooted the phone then you can install ROM Manager which can be used to flash the latest CWM recovery image.

you are providing wrong information,
ROM manager does not work with some kernels and could potentially result in a software malfunction,
@op and everyone else having the same question:
please just read the original instructions from the kernel developer to ensure success of the installation

Nexus 4 lag after kernel restore

Hi Everyone,
I have stock rom with franco kernel. Yesterday I reverted back to stock kernel and noticed that it lags now when I wake it from the unlock screen. I did a factory reset, but the lag is still there. This was never there when I had it from the begining. Should I flash the factory image?? Can the backup stock kernel get corrupted?

Try _motley's reset kernel, it restores other files that may have been changed too

Edit.. Note the link is the 4.2.2 version, check his thread if you need 4.2.1 reset.

after using franco kernel, you have to reflash your rom then kernel. franco kernel hides tweaks inits ramdisk. flashing another kernel on top will not change this ramdisk, so you have to flash your rom first(no wiping anything).
As I stated above...can I just fastboot then flash the factory image??

absolutely. then youll need to reroot. its MUCH easier to flash a rooted stock(thats what im guessing you are using) rom though.

You can fastboot flash the OEM boot.img; I'm guessing you fastbooted Franco's kernel?
http://forum.xda-developers.com/attachment.php?attachmentid=&d=1361814949
Flash this reset kernel which has the INITFRAMS.
all will be ok.
You don't have to reflash the whole phone.

Either way, you can just flash the stock boot.img via fastboot and you're good to go.

I suppose I can...however....I currently have a chromebook (ARM)...dunno if I can use fastboot with it. I wanted a solution I could do straight on my phone, like, flashing CWM recovery, then downloading the stock (rooted, CWM flashable) ROM...and flashing it.

Could you clarify this for me, If in the future I need to do it? So, after leaving franco kernel, i.e. If I'm using franco kernel and wanna go back to completely stock again; before flashing stock I'll need to re-flash the current rom that I'm using, to re-flash the rom's kernel and this way replace the ramdisk to the stock from rom? If I'm wrong, please correct me; you guys are awesome!

yes, kinda. reflashing your rom will replace francos ramdisk. all the other kernels use anykernel, so dont have ramdisk included. generally, its only after using franco kernel do you want to do this, the other kernels you can flash right over each other. anykernel kernels grab the available ramdisk. theres plenty of stock/aosp rooted roms here on xda, any of them should work for you.

you have made alterations to your phone so its not longer stock. the file you are flashing is for a stock rom and to be flashed in a stock recovery. to flash the update simply re-flash a stock recovery and allow the update to go through. you can also simply wait and flash an updated custom stock rom.
Edit: link deleted....may confuse you
Edit2: Using the toolkits you should be able to find the stock recovery image and flash it back

Thanks for link but Wow....I'm confused on what all I need to download.
If ur looking for stock rooted use one of the TW roms...3 links titled 'stock mdl or mf9 or mdc' depending on ur update. U can find that out by checking 'about device' under settings/more. Its the last 3 letters of software version.
Hope this helps.

You can just use any stock rooted rom but make sure you do a factory reset.

this is what Id do...someone jump in if I am incorrect about something...
your on sacs, so you must already have a recovery - twrp or cwm.
See what update you have...mdc, mdl, or mf9 and download that stock ROM zip file.
Find a stock kernel listed down on that page and download that (since you want the stock experience).
put both on your sdcard.
boot into recovery and wipe data/cache/davlik ( I do it 3 x)
Flash the ROM, then flash the kernel.
I think that should do it.

[Q] Help with installing Stock Kernel and Stock Recovery

Hi guys
Really struggling to find the Stock Kernel for my Note 3 and how to flash.
From what i've read on other forums, everyone seems to say you just flash stock ROM via Odin however this has proven not to be the case when i have flashed.
Any help is appreciated, Thanks!

so what your saying is that you tried to flash the stock firmware via ODIN and the kernel did not revert back to stock kernel ?

Yes that's exactly right. to check if it was a one off i'm currently flashing stock ROM again via Odin as we speak.
it should work that way but if it still doesn't work, go into recovery and WIPE all and then reflash Stock.. that should work
