[Q] How can I return to stock kernel ?

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.

Thanks, I have some questions because I coudln't post a reply to that post.
-I live in egypt and I bought my tab from the US, this rom is for the US so should I flash it normally? (will I get the OTA updates)?
-should I backup my data and so? (sorry it's my first device)

You should get ota's as its 100% stock. As far as flashing it no need to backup anything. You won't have root or cwr to use your backup. Flash via Odin and you should be good to go.

*I done that for my Galaxy Ace, I believe should be the same.
reverting back to Stock from CWM all you need is Odin and stock firmware which able to obtain from sammobile.
flash is with stock ROM via Odin will bring everything back to stock. *after flash, make sure swipe your data & cache OTHERWISE it will stuck and become boot-loop.

I did flash the stock ROM and recovery via odin, and it worked perfectly, thanks for the info thought because once I forgot to wipe data and it was stuck on boot-loop till I reached recovery mode.
I meant isn't there a normal way to go back to android recovery without flashing new ROM?

Can't really have stock recovery AND root... seeing as you install root via CWM
Besides you can do way more with CWM over stock.

he any one knows the link for uninstalling cmw in p3100
and also the unroot package

Create a new thread,don't post on an old one.

If you are rooted with custom recovery you can flash only the stock recovery using mobile odin.

getting back to original recovery from twrp recovery
i have karbonn smart tab 10 (cosmic) .i have installed twrp recovery on my tab. but i cant find any zip files when i go into recovery and twrp is not working properly.i cant even root my tab. i want to go back to original recovery.please help.

Do you have a P5100 , P5110 or P5113 ? It don´t sounds like!
If not - don´t use this files! This might brick your device!
If you don´t have a P51XX you need to find a Stock-Recovery or Custom-Recovery for your Device.
If you have P51XX download and flash a StockRom - or extract the recover.img inside the XXX_HOME.tar.md5 and make it Odin-Flashable using this tool and flash it with Odin.

[Q] N8010 stock recovery

Hi
I've searched restoring the stock recovery menu but I have some questions.
I know you can flash a stock recovery after, saying, you flash a CWM recovery.
http://forum.xda-developers.com/showthread.php?t=1831173
This guy uploaded a stock recovery but it says N8000, and I have the N8010. Will it matter?
Another question: when you download a stock firmware from, say, sammobile.com, does it include the recovery?
Thanks

Stock recovery is part of the firmware .

If you want to be sure to have a stock rom, go into apps, supersu and unroot before flashing...
Mind you, once you flash a stock rom it should restore the recovery and get rid of root access...

[Q] Help Restoring P5110 to Stock

I am looking for some help regarding my Tab 2 10.1.
My tab was rooted and then flashed with Cyanogenmod 9.1.
Also ClockworkMod recovery 6.0.2.7 was installed.
What I want to know is how do I restore it to its stock firmware and have it as if it was new, root free with no evidence of custom firmware i.e reset flash counter
All help welcome!

I was in the same exact situation, i am now back to official stock rom with no signs of mods. Here's what i did. This works on all galaxy tab 2 devices by the way.
-First download stock official 4.1.1 p5110 rom and flash it with odin.
-Start up your tab to see if it's back to stock rom.
-Next you have to root it with CF-autoroot and flash it with odin.
-You should now have stock official rom with stock recovery and a rooted device.
-Now download Triangle Away app for free over at the XDA forums (google it) or support the DEV by purchasing it on Google Play.
-While using triangle away, reset the flash counter, the app would then close after it's done. Make sure that triangle away did the job by opening the app and viewing the status Official with 0 flash counts.
-Now open SuperSU and go to settings and select full unroot, your device would then be unrooted.
-Lastly, put the tab to stock recovery mode and factory reset the tab.
You should now be good to go as if you have never modded the tab, to confirm, go to settings<status and check what it says on the status. If it says official than you are done.
NOTE: Be aware that Triangle away is said to hard brick your device if mishandled, according to the DEV. However i have never bricked my device over the dozens of times i have used this nor have i seen anyone brick because of this. For more information view the XDA Triangle away post.

If you have a stock ROM, it will run /system/etc/install-recovery.sh which will re-install the stock recovery. If you're rooted, that's the easiest way to get the stock recovery back (chmod 544 /system/etc/install-recovery.sh then /system/etc/install-recovery.sh)

The firmware should come with Stock Recovery. If ODIN do not flash it with Firmware then you try to flash the Stock Recovery only..If still not done then use Odin mobile ver and try.

Errors when updating on Samsung Galaxy Fit

My Samsung Galaxy Fit version was 2.3.4. I wanted to update it to 4. I found Cyanogen Mod but it didn't support my phone. I rooted my phone properly.:victory: I installed TWRP and flashed this ROM(from xda-developers.com) and Google Apps from the same post. Everything went OK.:laugh: Now, when I turn on my phone, Cyanogen Mod blue splash screen shows and two blue screens are spinning. After some searching I found that I got a loop. Now I cannot do anything with the phone. One of solutions that came to my mind is to flash a recovery(stock) ROM, but I can not find it anywhere for my model. The original, stock version is 2.3.3. I updated it via settings in Android.
What can I do now? To sum things up:
I have got a Cyanogen Mod loop
I cannot find stock image for my phone model
I do not know what to do!:crying:
EDIT: I found this http://forum.xda-developers.com/showthread.php?p=42924000#post42924000. I will try it and post what happened.

Hmmm i think you must find stock rom. Stock rom for galaxy fit is dxkt7.
Flash again with odin.

I flashed CWM 5 via Odin and reverted back to stock via CWM(http://forum.xda-developers.com/showthread.php?p=42924000#post42924000).
Now, I have a backup, if anything goes wrong, and I have version 2.4.6. Gingerbread.
You wrote I can flash stock ROM via Odin. I am just curios, how to do that? I have Odin multi downloader 4.42. I am asking this because I could flash Android 4 from there instead of CWM or TWRP(never again).
Anyway, thank you for answers.

The rom u flashed is slightly modified(for cwm) with some tweaks which r not there in samsung stock roms(like max upto 787Mhz, init.d tweaks etc...) However, the real original way to flash Gingerbread for galaxy fit is via Odin. Android 4 isn't officially supported for FIT so it's only custom supported in the form of CM10.x custom roms & hence, can't b flashed via odin.
