I'm not 100% sure, but you might could extract the boot.img out of your rom.zip and fastboot flash boot boot.img to make the kernel go away.
if not, i know if you flash the new Jelly Bean ROM that tachgi91 or ChongoDroid posted in the Dev section it will remove the kernel

If you flash any Rom it will get you to that Kernel and most have stock kernels .. but like he said you can flash the original kernel img through fastboot

[Q] changing kernels?

I've looked into many threads, but have still not been able to find a definitive answer: when changing kernels (going for example from ElementalX to Franco or Purify) should I do a dirty re-flash of the rom and then flash the new kernel or will just a flash of the new kernel be enough?
I know it's been asked before, but I can't seem to find a clear answer.
Thanks
Alex

Thanks for the reply.
So (just to make sure I have it correct) right now I am running Purity + Purify. If I want to switch to a Purity + Franco setup, I need to dirty flash Purity rom (in which case it brings the kernel back to the standard Purity kernel) and then Franco kernel after that, right?
Do I need to wipe cache or anything else?
Thanks again for all the help

You're right. To prevent any issue it's better to follow this rule regardless of the custom kernel. We need to dirty flash our current rom due to modifications done by the kernel on the ramdisk.
You never need to wipe before flashing a kernel.

Great. Thanks so much for the detailed answer, it clears up my confusion!
Now off to try Franco's kernel

I actually have an additional question: do we need the same process even if we're talking about the newer version of the same kernel? Like going from an older version of Franco's to the newest

No only when you change kernel you need to do it.

Its better to ask "Silly" questions and understand what you're doing than it is to brick your phone then ask for help.
We'll answer your questions, dont worry. Just ensure you read all the sticky threads in Q&A and General.

Yes, I consider your guideline (on your signature) very good advice indeed.

Just wanted to add to this...
If I'm on the stock ROM. I decide to flash elementalx. Then, want to switch to Franco or something, would I need to flash the stock img? Or can i just flash the stock kernel?

Wondering the same thing. If I am currently on stock rom with franco kernel, in order to switch over to elemental do I have to flash the stock rom zip from the thread here on XDA and then install the elemental kernel?

I know I had to do that when I flashed elemental. Otherwise some apps won't open. But now I want to find out was the the full correct way? Or was it the lazy way

Flash the stock boot.img and system.img and then flash the kernel you want to change to..
I have also tried just flashing the stock boot.img and then the custom kernel.. Sometimes it works, sometimes it doesn't. So I would reccomend flashing both! (boot and system)

also check to see if the original kernel left any init.d files, some kernels do. you would want to delete them, as those could, probably would, not play well with your next kernel.

another noob question,
does your advice still applies if someone flashed both stock system.img and stock boot.img?
if it is where that file will be located?
thanks.

yes. they arent located in either of those locations, so my advice applies, and is the only reason why i posted this. they are located in /etc/init.d/. you either dont have that location (best option), have it but an empty folder, or have an init.d folder with files in it. if there are files there, delete them.

Flashing a system.img will overwrite init.d scripts. /etc is a symbolic link to /system/etc so when you replace /system/etc with whatever is in a ROM.zip or a system.img, these changes apply to /etc too.
If you look in any ROM.zip or kernel.zip, they all flash their scripts to /system/etc/init.d

[Q] Mahdi rom

Does the Mahdi Rom work with Franco Kernel R4? I have this kernel on my stock 1+1 64gb international version. Reading on the developer forums some say yes and some say no that it causes reboot issues. I am just trying to get some clarification on this issue. Thanks

Yes it works with it, but only the version posted in the mahdi rom thread
Few users have reboots, many don't

Mahdi Rom
Do I need to add the kernel off the op page or just use the one I already have in twrp, it is the Franco kernel r4. It is the same one that is on op page I think. I see some people talking about dr87 twrp. I just have the stock 2.7.1.0 twrp installed. Do I need the dr87 twrp? Sorry for the noob questions just trying to it get right. Thanks

Use dr87 twrp and dr87 franco kernel r4.
I'm using both on MAHDI and it works perfectly.

Just one more question. Do you flash the dr87 twrp right over the stock twrp or do you have to remove the stock twrp? Thanks for the quick reply and all the help.

It doesn't matter what recovery you have prior to flashing, flashing dr87 twrp will override whatever recovery you were using before. Fastboot flash it or use the flashable zip to flash it. Up to you.

MAHDI ROM
I flashed the dr87 Franco kernel today and never got past the one+ screen on boot up. I was just wondering if I needed to flash Mahdi rom first and then flash the dr87 Franco kernel? I did get the dr87 twrp installed and all is well with that. I re- flashed the Franco kernel r4 and I'm still on the stock cm rom and everything is good. After reading the MAHDI ROM forum it seems they are having problems with this.

Simply follow the steps in the MAHDI OP post.
Its pretty much.
1. Factory Wipe
2. Flash MAHDI then gapps or kernel (doesnt matter if u flash gapps or kernel first).

Are they getting all the bugs worked out of this and is it ready to roll? I kinda have been waiting a little while to see how everything is going to play out. It seems like it is getting better and better. Let me know how you feel about it. Thanks

What do you mean by bugs? Check the third post in Mahdi, theres a working bootable Franco kernel again

About flashing a new kernel

Hi everyone, I have a question about the Ak kernel. I an currently using the stock rom , would I be about to flash the ak kernel using the stock ROM? If so, which version should I flash? My device is rooted.

It looks like this one was the last build he did for CM11S. The full list is here.

Yes, it has CM11S in the kernel filename, as long as you're on the most recent build of CM11S (44S) it should be fine.

Custom kernel flashing

Hi guys!
I'm using the lastest MIUI 7 Rom and i was wondering if I flash a custom kernel like Sensei, will the rom still work?
Also, if I flash CM13 with that kernel and then I want to go back to MIUI, will I have to flash the stock kernel?
Thanks!

My kernel works only with Miui6 as reported by @davtse as the're significant improvements on the partitions of Miui7... You don't have to flash back stock, just use MiFlash and it will handle all the fuzz of flashing back Miui.
Hope this answers your question.

I am on CM13 + Sensei.
If I want to update CM13 (dirty flash?), I don't have to flash stock kernel before doing that, right?
