How do I get back to stock kernel? - Nexus S Q&A, Help & Troubleshooting

I am running stock jelly bean rom with air kernel and I want to get back to stock kernel. How would I do that?

Just flash your rom again, no wiping required

Ok so I just flash the last OTA update I had which was the 4.0.4 to 4.1.1 update?
This one.

No, you flash the full ROM. Not just the OTA update.

Where is the full jelly bean 4.1.1 rom? Sorry I couldnt find it.
And are you positive this process doesnt wipe that?

https://developers.google.com/android/nexus/images
Make sure to grab the correct one. Flash with fastboot. Obviously your bootloader has to be unlocked, which I imagine is already the case.
Nothing should be lost as long as you don't wipe data.

Ah so this is what I have to do?
http://forum.xda-developers.com/showthread.php?t=1572307
And yes my bootloader is unlocked.
Btw which kernel do you suppose is the closest to stock kernel? The reason why I want to do this is because I wanted to see just how does the stock kernel compare with air kernel but it seems like it isnt as simple a thing as I thought it would be to go back to stock kernel.

as i know there is no stock kernel standalone instalation package. So the only way to get back to stock kernel is to flash the whole ROM again.
For my purposes showed as the best kernel thalamus kernel.

Thanks for all the info guys. I have one more question just for future information purposes. Do you get an OTA update if you are on custom kernel?

I just re-uploaded the ROM with stock kernel on my thread:
http://forum.xda-developers.com/showthread.php?t=1881858
That will reset your kernel to stock. Sorry I don't have a separate kernel zip to flash.

If I install my compete ROM again (its Cyanogenmod), do I have to install the Gapps again too?

How do I do an ADSP firmware update?

I installed the JB ROM JellyTime Beta 7 fine. When I installed JellyTime Beta 8, it hung on the Jellybean boot screen. The OP of the JellyTime thread told someone else with the same problem to update their ADSP firmware for new kernels. I searched and searched, but I couldn't find a reference to how do do that or what it even really was. Could anyone help point me in the right direction?

Sure wish i could get some help with this too.
Have you guys tried the latest releases? When full wiping include format all partitions except sd card.
Sent from a dream.
What latest releases are you referring to? Could you please be more specific?
EDIT: I did a full wipe and reformat of everything, including system, data, and cache.
Right now they are on beta 10. Funny thing, I don't recall anyone mentioning a need to do a adsp firmware update. I don't even know what it is.

I upgraded my radio and ril and it still would not work. I then flashed a stock htc ROM that had sense 3 and then it would take beta 10.

That is the one. But if you don't do a full wipe before you do beta 10 it will have errors. It would still boot but have lots of errors.

In case anyone is looking for a solution and finds this thread, I can confirm that flashing the stock ROM, wiping, and flashing Beta 10 works.

It worked for me as well.
along the same discussion I'd like to ask another question about the new 3.0 kernel.
I'm a weekly ROM changer and usually run IceColdSandwich. Once I switch back to ICS and want to reflash JT to check out the latest improvements/updates, do I have to re-flash the GizRoot_v_2 with the 3.0 kernel then flash JellyTime? Would it work If I did a backup of JellyTime and tried to restore it when a new update comes out or does it become non flashable once I've returned to the older ICS kernel?
In other words, can I flash between ICS and JT without having to go through all the steps to reload the 3.0 kernel?
Thanks in advance to a great community!

Nope. You only need to flash the stock once; after that, flash back and forth to your heart's content.

IceColdSandwich runs on a 2.6.5 kernel, and will not work with a 3.0 kernel. Jellytime runs on a 3.0 kernel and will not work with a 2.6.5 kernel. Both of those ROMS have their respective kernels included. You only have to flash the ROM. I'd also recommend a full wipe before each flash as well.

usspatriot is actually referring to a separate question. Some of us need to update our firmware to run JB, which can only be done by flashing the latest stock before flashing JB. He wanted to know if the updated firmware would be overwritten by flashing ICS, requiring a reflash of stock before reflashing JB. The ICS and JB kernels are not at issue.
I wonder if this has anything to do with my issue with JB on a Desire HD:
I came from SmartDroid_Reloaded_wwe_1.5.2, did a full wipe, installed, everything works fine for me except for cellular data.
I'm wondering if it's something to do with JB not liking my phone? I've also tried a couple of ICS roms.. See below:
SmartDroid_Reloaded_wwe_1.5.2 = cell data works
Sabsa_Prime_v5.0 = cell data works
TrickDroid_v1.1.1 = cell data works
cm-cfX-20120925-OFFICIAL-ace = no cell data
cm-JellyTime_R10 = no cell data
cm-JellyTime_R10.1 = no cell data
cm-JellyTime_R11 = no cell data
i set my APN's to suit my network (crazy johns in australia) but nothing works..
If i connect to wifi, both the wifi signal and cell signal turn blue, if i disconnect from wifi, both turn grey.
MMS, SMS, Phone calls work fine..

Can I flash a custom Kernel with stock 4.1.2.?

Hi.
I'm going to root and unlock my device this weekend. I can't settle on a ROM because I want a steady ROM and a really stable ROM. I don't want to be flashing every 5 minutes.
Basically I just want Voodoo sound badly on my device. I am running 4.1.2 at the moment.
Is it possible to flash a custom kernel with stock android?? I have read you need to delete a file before flashing on 4.1.1. Is this still the case on 4.1.2.?
Can anyone recommend a Kernel?
Thanks.

Yes you can do it. I suggest you to try Marmite Kernel v5, it's really smooth and it has a good battery life.With this kernel you can stay with your stock Jelly Bean 4.1.2, like me, and use a custom kernel (Idon't have to delete any file, I root my phone flash the kernel and gooo)
Wow thanks for replying.
I have heard many good things about Marmite .
So I defo don't need to delete anything from stock 4.1.2. Before flashing the Marmite kernel?

Nop, just flash via fastboot a custom recovery (recomend TWRP,link below) and root your phone with supersu or superuser zip.
then flash your kernel (dont forget to wipe cache and dalvik cacche before flashing the kernel)

Hi.
I was going to use CWM as I have used that before back in the days of the G2/Hero.
Would CWM be OK?

Yes with CWM no problem with flashing this kernel
Hi all.
Well today I gave it a go. I managed to flash my NS using the guide by gullu101. Everything went fine.
I have downloaded Voodoo app and have Voodoo sound at last! :good:
I also flashed Marmite kernel V5, but I have a few questions.
I'm still on stock 4.1.2. and used Marmite V5 Stock OTA zip.
After flashing the kernel I noticed that I had no extra options in the settings menu. I take it because I'm still at stock these options aren't available?? If I was to flash a custom ROM and the 'All Other Roms' Marmite zip I would have these options?
Another thing, after the factory reset I had to install a few things from the market. I also got an notification exclamation error which I had never had before, it said 'need google play services' and took me to the Play store to install it. I have never had to install this app before and I'm wondering what it is.
Thanks.
install NS tools then you will have the "extra options"
Do I need to flash that or can I get that off the market?
Tbh I'm not bothered about tinkering. I just want to know that leaving the stock marmite kernel as is will be fine for my phone?

it's just an app you can download at the google play store.

as long as your rooted, yes. install BMM, follow instructions in its thread, and flash ROM.
Black screen issue should be fixed without needing JBX.

porraxenieze, afaik a prerequisite of JBX is to be first on a kexec kernel. I u/s what 'MotoMudder' is saying but I am unsure how jbx plays in a multiboot environment, I mean if for ex if someone has stock unoffficial (official) JB leak on sys 1 and on sys 3 if one installs 4.3 kexec PA or say kexec 4.3 Slimbean & then flashes jbx, what happens??

do i have to do the partition and install on system 3 or can i just install it, dont do the partition and install it on system 1?

I would partition. JB ROM's are far from stable, and never will be without kernel source. Always nice to have a stable Daily driver on your phone to fall back on.

mmm okay i guess, i will see it then, when i do the partition the systems 3 - 6 can only be 1gb max right? that means you only have that much to install on the internal memory? seems low..

Well, if he doesn't have issue with signal, then you shouldn't have to flash the new ML1 modem. If you want to flash it anyway then here http://forum.xda-developers.com/showthread.php?t=1788313
There are a bunch of custom rom, either TouchWiz custom rom or just custom rom you can choose from here http://forum.xda-developers.com/galaxy-s3-verizon/development
If you want to stay away from bugs, pick the one that close to stock rom as much as possible.

[Q] About rooting and custom kernel

Ok here is the thing i have few questions about rooting my device and flashing custom kernel.
1) I want to root my nexus 5 and yes i saw the tutorials its not my first time to root a device but its first time on n5 so if i root it and install custom recovery and keep stock rom and kernel will i be able to recive ota updates without any problems? Or if i just root it and keep the stock recovery will i be able to update?
2) And my second question will franco kernel work fine on stock rom? Because if my first question is not possible then i would flash franco kernel on my device too and later when an update for stock rom comes i would flas it manually of course if that is possible too?
Thanks for help.

No because you're rooted it won't accept the ota update due to modified software.
