[Q] About rooting and custom kernel - Nexus 5 Q&A, Help & Troubleshooting

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.

[Q] does root, DeOdexing and Switching kernels break updates?

I'm using a stock DeOdexed rom, rooted by ADB & netarchys stock kernel.. will I still be able to receive updates from google??
I believe you'll receive a notification but you won't be able to update.

You need not worry about it. I promise you, if you are the kind of person to be rooted and running custom ROMs and kernels, you will certainly be flashing the update manually far before 99% of users get any OTA update
I know to flash the update you might need to be on stock, but you can always flash stock then update.

How do I get back to stock kernel?

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.
http://forum.xda-developers.com/showthread.php?t=1736645
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?

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.

Yeah just dirty flash the your ROM and you'll be back on stock kernel. You could always try to find the stock kernel somewhere and flash that.
Also, simple questions like this could be asked on the main Questions thread on this forum. Just keep that in mind next time

#2 post, Section 1a - Pre-root Info: read it
But is a beta version! :crying: I want it to go better with stock Android.
If you need extra features then do so. If not, I do not see the point of it. Anyhow, I suggest you use multirom so you can easily try all those roms out there.
No, I do not think I serve other customizations .
Then this thread is pointless. Close please
This means that the stock is fine, ok thanks.
Personal preference. If your not happy with stock then get a root. I suggest rooting the stock rom first before you try roms tho. You have alot more options for customization to the stock if you do that.
OK thanks I understand, if I want another options I root my device or I flash another ROM. A Stable ROM!
