Basically I've never flashed a custom kernel before so I'm trying to do some research so if someone could give me some incite or point me in the right direction I'd really appreciate it.
The only thing I'm not sure of is if I flash a custom kernel will it prevent me from receiving any future ota updates? If so, any ideas where to find a flashable stock kernel? I couldn't find one. I really want to stay with the stock rom. Had my fill of custom roms on my phone.

Let's see. AFAIK yes, non-stock kernels will prevent you from getting those long-awaited OTAs (not sure though as the first thing I did after getting my N7 was to flash PA ).
If you really like the stock experience but still want a custom kernel, you must flash a custom recovery to flash kernels. The latest TWRP touch is what you need.
After you've flashed the recovery, just download the kernel zip, reboot to recovery, flash, profit.
As for a kernel, you can go with M-Kernel, DerKernel, franco.Kernel, Faux and so on and so forth. I love M-Kernel personally. You can tweak it with TricksterMOD for a smokin' good overclock as well as purty good battery life
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Also, just asking, what do you mean by a "a flashable stock kernel"? If you already have the stock kernel, why flash the same over it?
AFAIK updates to stock kernel are provided by OTAs.
I guess I was looking for a way to return to the stock kernel if need be. I have my recovery and understand that part. Just trying to make sure I understand kernels better before I brick my n7. Thanks for the help!

Oh, ok. If you flash the stock ROM, it flashes the kernel as well (but it's a lot of work reflashing a ROM just for the kernel )
What you can do is this: extract the stock ROM zip and flash the boot.img you get.
Here's a link to the stock ROM: https://dl.google.com/dl/android/aosp/nakasig-jop40d-factory-efcec044.tgz
Edit: I figured I'd explain the rest as well...
After you download that file, untar it: nakasig-jop40d-factory-efcec044.tgz will untar to a folder probably named:nakasig-jop40d-factory-efcec044
Open that folder. You will find a zip (probably image-nakasig-jop40d.zip or something like that), unzip it.
You'll find four files. boot.img is the one you need. Flash it to your device with fastboot.
If you wan a flashable zip, unzip any custom kernel, replace the awesome custom boot.img with the boring stock one and rezip. You should be able to flash it from TWRP or CWM.
Note that the stock kernel nukes CWM on first boot. I assume you don't have root. Do this:
1. Connect the N7 to your PC. [you should have debugging enabled in dev options]
2. Open an adb shell and type this: mv /system/recovery-from-boot.p /system/recovery-from/boot.p.bak
3. ???
4. Profit
[If you do have root, open a file manager, remount /system as read/write and rename /system/recovery-from-boot.p to something.]
Click thanks if I helped!
That's why I was hoping to find the JOP40D stock kernel as a flashable zip. But I'll give the boot. I'm a shot. Thanks again!

stock flashable 4.1.2 kernel for grouper(put up by faux as a "reset" kernel) http://faux.androidro.ms/grouper-faux123-reset-kernel-4.1.2.zip (should be fine on 4.2.1)
flashable in twrp or cwm recovery. no hoops to jump through flashing or after flashing this. it doesnt nuke your recovery.

Your last resort could be to flash the stock image. You also didn't mention which rom you are using.

No, i would use adb for that, look in my sig how to set it up. Adb is much more reliable than a toolkit and you`ll learn something
Oh ok im a little iffy with adb i was hoping there was a way to flash stock just like you can the custom... But i guess if i have to ill look at how to do it that way.
You use fastboot not adb

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?

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??

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.
Anyone else have the issue of it just continuously trying to boot? I'm using the CWM auto-loki that's in the development section.
Reflashed it three more times. Now it freezes @ Samsung battery screen when charging, or if I wait long enough it'll unfreeze. Still loops at Slim Bean startup, what sucks though is that for one thing it mounts as an MTP device so it seems like it's on but just not initializing, another thing is that the original flash I was able to get to the slim bean battery charging screen (but obviously still couldn't turn it on)
Thinking it might be a kernel issue, since I installed ktoonsez's AOSP kernel when I installed it. Any recommendations of a kernel to use? I'm using the CWM recovery that has auto loki so, I could probably use ones made for 9500,9505, etc.
(Pasted this from the Slim Bean thread, haven't gotten an answer in like 5 hours and it's a little urgent xD. I'm on the AT&T S4 of course, any other information I'll be glad to provide. Hopefully this is just a simple fix)
I bet is related to the kernel. I have been using Slim Bean flawlessly, with none of the issues you mention. Using TWRP to flash and recover.

I installed Slim Bean with Ktoon kernel and it worked fine. Just make sure to wipe system and the caches. It did take a little longer to boot the first time but after that it was all good.

Isn't ktoonsez kernel for a Touchwiz based ROM?
Slim Bean is AOSP, therefore i'm not sure they jive correctly, which would clearly explain the OP's problem.
EDIT: Didn't realize he updated an AOSP based Kernel. In anycase OP, I would still attempt using the stock kernel to see if you problems get fixed.

Patching a patched kerenel changes nothing. Dan said if you run loki on a patched recovery or kernel it just send the original to the output. Nothing happens.

I know someone else clarified this already, but when I downloaded Slim it actually wasn't Loki patched for whatever reason, and I couldn't boot without reinstalling stock. I did download the one in the right thread, it just didn't have a boot.lok in it for whatever reason. Anyways, I'm gonna try reflashing and wiping /system another time, wish me luck. I don't have the original kernel backed up though because I'm an idiot, so does anyone have a link to that? If not I could probably scour it out somewhere, but just wondering for convenience's sake.

In advanced restore boot is the kernel.
Download the ROM and addons again, you shouldnt have any issues... If you are currently on stock, do a comprehensive wipe, a manual format of system and data

Oh my lord, thank you good sir. Slim Bean is up and working as of right now ^^;. May be a little bit before I apply a custom kernel though o.o
So, i was in a hurry and i downloaded the wrong kernel. I wanted to download the linaro franco kernel for android 4.4, but instead i downloaded this one "franco.Kernel-nightly-r14-linaro.zip". this is an old version.
So now, my device does not boot and i cant install the correct kernel file.
What should I do?
Use a toolkit like wug and install through it the stock or any custom kernel you want.

But...
But, there is a way to only replace the kernel or i have to re-install the ROM?
Re-install only the kernel may affected something?
