How to get back to stock kernel from fanco kernel? - Nexus 7 Q&A, Help & Troubleshooting

I flashed franco kernel, and now i feel stock kernel maybe better.
How can i get it back?
I'm using stock android 4.1.2 and franco kernel (with rooted and unlocked)

As long as you leave the volume mods alone Franco is better than Stock kernel

Question about franco kernel ????

Hi everyone!!! Everytime when booting my phone, it's stuck on Google Logo, I have to to fastboot it with franco r14 kernel in order to get it booting done. Is there any way so I dont have to fastboot everytime I restart my phone, flash to stock kernel or franco r15 ???
I tried to flash faux123 kernel but it just did not work, stuck on Google logo...
If I recall correctly, franco kernel uses a different ramdisk so before you switch to another kernel you have to return to stock (kernel)
I suggest return to stock kernel, then flash franco r15.

This is what faux suggest to use to reset to stock kernel, for stock ROM only.

If you're in franco, before you switch to another kernel you have to return to stock kernel.
I don't know why you're stuck with Google logo in the first place with franco, but if you're just switching between kernels, especially when there is franco kernel involved, return to stock kernel will likely solve the problem.

[Q] Switching ROM and Kernel precaustions

If you flash a brand new ROM to your phone does the kernel (and RAMDISK changes) go away?
I'm asking because I have another Kernel and ROM running on my phone and I'm thinking of flashing a new (completley different) kernel and ROM as well, a lot of kernel developers require you flash a stock kernel before switching to another kernel, then flash the kernel of choice.
I'm scared to brick my phone...
So what would be the steps I need to take to change kernels and update my current ROM?

Which kernel are you planning to switch to?
When you need to flash the stock kernel first in order to flash their kernel, they will tell you in the OP. You can flash the stock kernel every time you flash a new kernel if you like.
I'm swittching from Motley to franco, I'm staying on the same ROM (xylon)

Just flash Franco's kernel as is. No need to do anything else.

[Q] Can somebody share a rooted stock kernel of JDQ39 4.2.2?

I flash franco kernel without backup the original one. I found a stock kernel in alternative post however it is no rooted. Can somebody share the rooted stock kernel of 4.2.2? Thanks.

Uhm, root is not in the kernel mate. Just flash the stock kernel and you will not loose root.

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??

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.

Lost my Original kernel - Nexus 4

Hello XDA-Developers,
I lost my stock/original kernel from my Nexus 4 Device..
I have now, Franco Kernel 3.4.0-franco.Kernel.nightly.
But, now I wanna try Faux123, how can I get my stock Android Kernel back?
Thanks..
Nexus 4
Build-number: JWR66Y
reflash your stock rom, or flash the stock kernel. a quick search on xda or google will find them for you. btw, you didnt "lose" your stock kernel, you willingly and by your choice gave it up by replacing it with a custom kernel.

flash the last good kernel or another kernel, or reflash your rom.
OP, this is why you make a backup before you flash. Always.
Also, You're*
