How to get back to stock kernal - Nexus S General

Hi iv been on a custom kernal for a while now and want to go back to stock... only the kernel is custom. The rom is stock
I can restore my old backup but ill lose too much stuff. Is there anyway just to install the original kernal to make it all stock?
Thanks

Reflash the stock rom on top. Only wipe cache and dalvic cache.

Kernel Manager in the market

If I relfash stock will I lose everything?
Also I thought you couldn't do that as it moans about something being modified

Also kernel manager doesn't have stock kernels

As long as you wipe only what I told you everything will be exactly the same except you will be on the stock kernel. You may need to update some apps in the market, but the data will still be there

Custom rom/recovery

Okay so like many of you cwm isn't sticking and when I go into recovery I just have the Google logo, I want to flash ROMs so installed ROM manger and found that if you boot into recovery through that app you can get into cwm.
Would like some advice on which is the best and safest method you have used! Thanks

My cwm didn't stick and when I manually go into recovery it hangs on the boot screen. ROM manager seems to work

use twrp recovery, its better(more functional) and isnt buggy.

i assume so, since i use it over and over and over again. anyways, theres a file you have to remove or rename in the /system/ fs that causes the recovery to not stick. most custom roms already have it removed, stock rom you have to remove it. the file is recovery-from-boot.p, rename it or remove it and your recovery will stick(at least twrp, cwm should also).

(Q) rasbean

Alright I'm doing something wrong. I'm coming from stock with Franco kernel. I wipe system, cache/devik. Then I flash Q rom/Ras gapps, der kernel trinity four. I think this is the trinity that's mentioned in the post.
Well when I'm done I get a boot loop.
Were did I go wrong?

Did you wipe data/factory data reset?

No I'm guessing that's the issue? Will I lose my back twrp back up?

no, youll only lose your user data. if you only wipe data/factory reset, your storage wont get touched. no need to wipe anything else. wipe data, reflash the rom, gapps, and trinity kernel, then you should be fine. whenever you flash a new rom(not an update to the same rom), you want to wipe data/factory reset.
Just needed to factory rest, thanks guys
Under kernel info I get dirty-morfic, is that trinity?

Need stock kernal

I've been using yargs for about a month now and always seems to have problems with my WiFi dropping. I made a cwm backup before I flashed yargs but would hate to have to revert my phone that far back.
I'm on newest ota rooted and unlocked.

Restore just an earlier system to restore kernel.
I have not seen a stock zip but I bet arrrghhh's Q kernel thread has one.

I think you could RSD straight to the OTA without wiping data. That should work. Or you could extract the boot.img from the RSD and flash it via fastboot

Thanks for the solution but I was hoping for a flashable zip. I have yet to dabble with RSD and am sorta nooby with this stuff.

Checked out his thread here on xda and didn't see the RAZR m stock kernel.
I have a cwm backup from when I was using stock kernal. Anyway I can extract just the kernel from that?

No. But you can restore just that system. Wipe dalvik & cache, not data.
OR
Just reflash your rom. Wipe dalvik & cache, not data.

Get the full RSD XML from http://sbf.droid-developers.org
Then, open it using something like 7 zip. You should be able to find the boot.img in there.

How to flash a kernel?

I just wanted to know how do I flash a kernel? I'm on an aosp ROM and wanted to flash a kernel before I applied an update to the ROM. Thanks!

If you don't know how to flash a kernel I don't know how you were able to install a ROM as its nearly the same process.

Yea you just flash it in recovery then typically wipe Cache/Dalvic afterwards. However if you're flashing a ROM update you're going to want to flash the kernel after that since ROMs contain their own kernel that would just wipe out the one you flashed prior.

Can I flash a non stock kit Kat Rom

I have the flashable through recovery version of stock kit Kat. Since I did not use a LG tool to flash it, can I still flash another non stock kit Kat Rom or do I have to downgrade. I still have twrp so I'm guessing I should Be ok, just worried about partitions.

Do you have custom recovery? Then yes. Are you referring to ROM's like CloudyFlex, etc?
Ya twrp, went to install Mahdi Rom for d801 and got horrible reception and no data, so was curious if it's a kitkat doing it.

Did you flash the KitKat radio before flashing Madhi?
I flashed after installing , tried the new gummy same reception but with data, also flashed furnace 2.0 kernal but after install of ROM. Do I do it before?

You flashed this radio right? http://forum.xda-developers.com/showthread.php?t=2705509
Also, if you wish to use stock KK ROM's just wipe and flash away.
Yeah I flashed that and than tried a T-Mobile only modem, no auto rotate either so that might be the problem
