Anyone know of an app or a way?
You could install a custom recovery and create a backup of the entire ROM from the custom recovery or did you just want the stock kernel?
I want to be able to be able to revert back to the stock kernel easily after switching to another without having to reflash kitkat with Odin.
Will you be trying a custom rom? I ask because stock kernels tend to only work with Samsung-based roms. Most custom roms are based on a cm11 or aosp kernel.
ROM Toolbox Pro can backup your kernel. Not sure if the free version will though. You can check

1. Open ROM Toolbox
2. Choose ROM Installer
3. Swipe right
4. Choose Backup & Restore
5. Backup Kernel is 3rd choice.
6. Note backup location so you'll know where it is

Or, if u flash a custom kernel and don't like it and want to revert to the stock kernel easliy, just dirty flash the Rom again, no wiping needed...
I ended up flashing CM11 and I made a complete backup before I flashed.
Thanks for the help guys

Is there a way to back up the kernel on my existing ROM before I flash dumfuqs latest one? In case I don't like the latest one is there a way to revert back to the original kernel? Thanks in advance!

I might be wrong but i think the normal kernel is included with the rom and you just reflash the rom if you dont like the oc kernal (or nandroid backup)

after you re-boot into recovery using ROM Manager you select "nanadroid" and then select backup... it backs up ROM and Kernel

Ok I get that but I was wondering in regards to lets say if I install the new kernel and then installs apps and make system settings changes and then I want to revert back to the old kernel without losing the apps and system settings? Also I'm asking this because I'm thinking about flashing the dumfuq 3.5 kernel on Chiefs OTA update ROM. Anyone running this combination? Thanks.

Flash kernel, install ROM, done.
A lot of roms require flashing a certain stock firmware first though.
The usual process for many roms= make sure you have the right base ROM if one is required (example: stock .42), fastboot flash kernel, load kernel recovery, flash zip file for ROM.
Make sure to wipe the cache in between through recovery.

I am running IOKP 4.3.1 on my nexus. I have downloaded the OTA update for kitkat 4.4. Can I flash the 4.4 update from cwm or so I have to return to stock then flash it? I ask this because my stock backup will not restore due to md5 mismatch. Thanks for any advice.
Anyone?
Just backup, restore a flash the 4.4 ROM.

OK I've backed up iokp. Can I now flash 4.4 from cwm? Or do I need to flash stoc first?

You can only flash an OTA if you are on stock ROM.
OK but how do I get back to stock ROM then? My backup won't restore.

If you don't know how to flash back to stock manually you are probably better off using one of the toolkits in the development forums.

Tasssadar has some stock flashable zips here:

Don't forget to thank him if you use it.
They seem to be stock kitkat. I would need to flash stock JB and then flash KK though, yeah?

No. Just wipe(cache, dalvik cache, data, and system) and then flash KK and you are done.
Another edit: Since you can't use a computer for this, you should download a few other ROMs so you have something else to flash if something goes wrong. I would really only recommend upgrading if you have access to a computer. Things can go wrong very easily. Good luck.
Thanks very much!
They aren't update custom ROMs, they're like factory images. You just need a kitkat 4.4 custom ROM that you can flash in custom recovery. If you don't have custom recovery on your tablet, you need to use your PC to flash it, or just boot temporarily.
Afterwards, restore your tablet, clear cache and dalvik cache, install zip, choose your custom rom, and flash it.
If there is an update for a ROM (such like nightlies for CM) you wouldn't have to restore the tablet, just flash the updated custom ROM because it's just an upgrade.

Hey everyone,
last week I flashed my girlfriend's XMS with several custom ROMs, but none of them could really satisfy us, so I want to re-flash the stock ROM.
My question is: Can I just flash the ftf file with the flashtool if there is currently CM11 running on the device? Or do I need to erase the system before?
Will this also flash "stock recovery"? Is there a way to do this?
Thanks!
Yes, you can flash stock ROM. There is no need to format system, Flashtool will do its work. Stock recovery will not be flashed, because we don't have stock recovery on our device. But you can flash stock kernel with CWM or PhilZ Touch recovery.
if you want to leave your recovery ..check kernel
sin in exclude list in flashtool

No! Phone will not boot with custom ROM kernel (if custom ROM is not based on stock). So it is necessary to flash full stock at first and then to flash stock kernel with recovery, if you want to have recocery.

You flashed stock via Flashtool after CM11 or CM-based ROM without flashing stock kernel? It should not boot, I think, because 4.3 and 4.4 kernels are different.
Has anyone tried this? I need to do this also but I'm a little bit confused about flashing kernel. I tried to find a detailed guide somewhere but no success
Hi! How can I revert back to stock kernel provided by the custom rom? Will I need to restore the backup (boot partition) in twrp? Or do I need to dirty flash the custom rom I'm in? I'm curious and new to this kind of things. Thank you.
