I am new to the nexus s , but have been a heavy galaxy s user. I noticed that flashing roms etc is a bit different from what I am used to on my galaxy s .. I did not see any thread containing stock kernels ... So how can I return to stock after I have flashed another kernel ? I have installed the voodoo kernel with ext4, sound and colour enhancement .. But suppose I want to return to my stock gri54 kernel , how can I do that ? Have read allready about fastboot etc etc but then I should have an .img of the stock kernel , correct ?
By flashing back to stock rom, you will get back your stock kernel automatically.

So by flashing back to stock ROM via recovery, does it mean that it will be locked and un-rooted as factory default [like when you first purchase the device]?

It will be unrooted, but still with unlocked bootloader.

The Odin package can put you back to stock rom too.
So what you are saying there is no way to flash only the stock kernel ?? Very confusing .. I am able to flash just another kernel using fastboot but I am not able to flash back the stock kernel using fastboot ? Odin is a last resort method .. haven't seen fastboot .img files of the stock here in the forums ?
I'm not sure if anybody posted any stock kernel file in the forums. If there is any, you can easily download it and install via recovery or fastboot.
Otherwise you can only revert to stock roms because stock roms links are easily available through the forums or samsung firmware website.
Or after you have failed everything, may want to consider Odin. It seems to touch the phone at a lower level compare to other techniques.
follow the instruction on this

work great for me after all
Samsung i9023
Good luck
Yeah , I also mentioned odin allready .. Used it a lot when I had my galaxy s .. Just thought that since the nexus s can use fastboot I could get rid of odin ..
I am also not used that all has to be flashed to achieve a single goal .. On the galaxy s I could flash the kernel separately and also stcok kernel were easy to find .. I think it is kind of a hassle to reflash a whole rom just because you want stock kernel back ..
Voodoo has stated that his kernel is 'almost' stock, with only voodoo addon to the pure stock kernel. Maybe you can use that?
Some news here?
Hi there!
I was also wondering about this same situation. Let's say I want to stick with the original ROM and try some non-stock kernels. After some tests I know there is an OTA available but I don't want to backup and restore everything (using TB or similar). From what I understood I wouldn't be able to flash stock kernel (in other words, back to full stock ROM + Kernel) and apply OTA update...
What if we just flash boot.img from a nandroid of stock rom+kernel?

Hoo great!
but, can you tell us where to find or how to get it from the stock ROM and make it flashable? It might be useful for upcoming releases of stock ROM/Kernels.
Thank you once again,
RM
edit: after searching by the filename you gently provided I found this:
hxxp://www.android-hilfe.de/2277361-post1.html
hxxp://www.michalurban.cz/Nexus_S_i9023/Kernel/
seems to be a good compilation, and stock is in the list!
The file I posted is already flashable through CWM. Just wipe dalvik first. Of course make sure you have a Nandroid backup just in case.
Hi,
sure, I noticed that. What I was wondering was how to get this flashable kernels. From the stock ROM full installation file? From a nandroid backup of a stock ROM??

Hi, is any chance to get stock kernel for Jelly Bean 4.1.1? I've got stock rom, Air Kernel and OTA is buzzing me multiple times a day. No luck in upgrade, Error Status 7. I think it's Air Kernel's fault.

I flashed this rom recently and everything was working fine, but I got stuck at bootloop after flashing the kernel using sgs flasher. So I flashed the non rooted version of this leak using odin. Now I can't root my phone using SOC. How can I root it? Would flashing the zImage from this rom using odin work? Any help would be appreciated.
There is no way to root the stock kernel...that's why I made a rooted version...to flash the stock kernel you have to disable voodoo lagfix in recovery....I posted that in op

Thanks a lot for the quick reply! Weird thing, I read that part but couldn't find voodoo on my CWM. Anyway I guess I'm gonna stock back to UCKD5 or something and then root/3e/CWM on top of it and later flash your rom.
Thanks a lot for the rom! Love UCKL2 so far!!!

To be able to root the official (non rooted) leaked GB roms, you just flash a custom kernel like Entropy's daily driver using Heimdall or Odin. Then, you have to install su and Superuser either manually with adb or with a CWM flashable zip. It's really not too hard to do. Once it's rooted, you just flash the stock kernel again for working video, etc. That's how I do it anyway.

I have a Moto G (XT-1032) unlocked. I would install cyanogenmod. My question is if i make a backup of the stock rom via custom recovery and can this backup restore later if i don't like Cyanogenmod or i must install the Stock rom via fastboot?
Thanks for all answer

You have to flash the stock kernel from Fastboot at least, because the stock and cm kernels aren't compatible. After that (in theory) you can restore your nandroid backup.

ok thanks for the answer. i will test it and answer later
okay i tested with two roms but these roms are based of stock rom. i installed these roms and after testing i restore stock rom from recovery. And it was all fine you don't need to flash the kernel from fastboot

Hi. Newbie here. I am new to custom ROMs and new to Android all together. I just installed CM on my Nexus 5 and really enjoyed it. Used wugfresh toolkit to root and then cm installer to get cm. I noticed after using cm installer I lost the ability to reboot to TWRP recovery. What's is the best way to go back so I can flash ROMs and kernels?
Fastboot flash a custom recovery and get rid of cm installer

i am currently on 4.4.2 with root and xposed framework already uninstalled from within the app, philz recovery mode.
when i try to install the 4.4.3 update (about 92 MB) it gives me an error on a specific apk (cannot remember exactly which one).
what are my best options? flash a stock 4.4.3 image and re root?
It's failing because of xposed. Try this

i am thinking and maybe the best for me is to make a fresh install (never did this before).
i have a couple of apps that i will need to have root and i also like keep the philz custom recovery
i never did this so i would like to know if it is safe to follow this guide:
How to flash a factory image | Return to stock | Unroot your Nexus 5
http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
i do not want to brick this. if i follow that, will i keep philz custom recovery? note that i am currently on 4.4.2.
and to get root again (after a fresh install of 4.4.3) will flash supersu.zip again be enough?
xposed is not needed for me and because of that i am havi all these troubles now, want to avoid that later.
edit: if i flash the file you posted, will it give me all the options i am asking right?

The link I gave you is the same as a clean install except you won't lose your data or custom recovery. You will lose root and will have to flash super su in your custom recovery. If you go with a complete clean install I'd use the link you posted. You'll have to flash a custom recovery via fastboot and then flash super su in it to root. My link will be simpler for you

I recently upgraded to 4.4.3 myself. Everything you need is in the stickies my friend. Flash the stock 4.4.2 factory ROM through philz recovery. When you upgrade to 4.4.3 you will lose your custom recovery but the boot loader should still be unlocked (mine was). Its okay, there are two options to get philz recovery back. You can use fast boot commands with the phone in the boot loader menu connected to your PC. The command itself and how to set up android SDK is in the sticky called unlocking boot loader, rooting and flashing ROM (or something like that lol). Option two is to use the app flashify available from the playstore. It will back up your custom recovery and you can use that to reflash it after you upgrade. I have not used it myself as I prefer to just use the simple fastboot commands in the cmd menu.
EDIT

Follow this tutorial on how to get your recovery back. Also the phone will no longer be rooted. There is a link in that tut to the superuser zip. Flash it through the custom recovery after you install it. You'll be rooted on 4.4.3 in less than 15 minutes from start to finish
