Kit Kat 4.4 which Linux kernel is it based on? - Nexus 4 Q&A, Help & Troubleshooting

Just out of curiosity I'm thinking of installing custom kernel in my nexus 4 stock 4.4 and wondering which Linux kernel is the official kit Kat based on. Because I know that all the custom kernels are based on 3.4.xx

Confusing, but franco says there's no such kernel http://forum.xda-developers.com/showpost.php?p=47358165&postcount=1095

kernel are per phone not per android version. our n4 will stay 3.4.x (maybe just devs will update to others versions but it will not be all that difference).

So i'm a bit confused... Are there any customer kernels specifically for 4.4 or wasn't the kernel updated from 4.3 releases and i just need one based on that?
I've been around the android scene for a long time but just not sure with this Nexus 4 i'm used to smaller community over at Modaco with more concentrated info. There's a lot of rubbish to sift through here
Or are we missing source to make custom kernel for 4.4?

kernel source for 4.4 was released today. trinity kernel is on 4.4 now

Mine is running kernel version 4.9.

Android 4.2.2 - Settings -> Security error

Good afternoon.
I am using 4.2.2 in my LG Nexus 4. It is rooted with SuperSU and I am using Franco kernel.
Every time I try to enter in Settings -> Security I receive an error. I already tried go back to the default kernel, installed the Clockworkmod recovery and wiped the Dalvik cache and the error continues.
I don't know if there is anyway to export this error report, so here goes the screenshots:
Thank you!
Assertion issues, what rom are you using?
It is not really recommended to flash a custom kernel on the stock rom.

The stock rom only works well with the stock kernel for multiple reasons, I cannot get into detail why custom kernels can be bad for stock ROMS.
I maybe can get to detail if you want me to.

What???
I am running stock ROM with a custom kernel (Franco), as are many others, and it's fine.
A custom kernel is usually just the stock kernel with some modifications (could be a tiny change or something bigger). What's wrong with that?

Its the first time I've seen someone say custom kernels aren't recommended for stock rom. So just curious to find out why that is the case.

It can go well but sometimes something can go wrong so I am saying that it really depends on anything on the device.

Sorry but this doesn't make any sense. Any app, ROM, kernel or whatever could have "issues", it's the same with any software.
Earlier you said that custom kernels shouldn't be used on the stock ROM and that's just nonsense which you don't seem able to justify. What's so special about the stock ROM which makes it less suitable than a custom ROM?
If a custom kernel has been designed purely for a particular custom ROM then maybe that one shouldn't be used on a stock ROM, but you seem to be drastically over-generalising. Most custom kernels are designed for any ROM on the N4, particularly since most custom ROMs are built on exactly the same AOSP base.

How to update 4.3 with Faux Kernel?

Hello,
I still have 4.2.2 and I want to update it to 4.3. Right now I still have the Faux Kernel from June 23rd.
How can I update it to the 4.3 Android? Should I put in the Stock Kernel and then flash Faux Kernel again? Or is there a new Faux Kernel which has the OTA Update for 4.3?
Thanks in advance!!!!
Nobody?

If you look at the faux kernel thread, you will see that the latest V19 beta builds are intended for 4.3.
However, from what I'm reading it seems that 4.3 isn't all that. Many people are being plagued by bugs and lag, reverting back to 4.2.2.
Personally, I'm waiting a month or so until the devs cook the issues out - it's not worth my phone having issues just for a new camera interface.
YMMV.

You need stock ROM & stock kernel plus baseband .48 to flash/update to 4.3

[Q] Noob questions about Kernel

my nexus 4 is running AOKP milestone 2 right now and it has the random shut off problem. some suggests changing the kernel.
question: AOKP is 4.2.2 now, can i run it with the 4.3 kernels posted in development forum, such as 4.3 AK kernel, or does the kernel has to be 4.2.2 ? If 4.3 is ok, I should flash the JSS version of kernel right?
thanks in advance!

Has to be 4.2.2 kernel. 4.3 kernels are not compatible, and on top of that, 4.3 kernels need to match the rom, either the open JSS15J or nexus 4 official JWR66 builds.
Try 1.4.1 (last build before switching to 4.3)from http://www.semaphore.gr, it has its own app for controlling the kernel.
You could also attempt the 4.3 AOKP beta build:

[Q] CM11 Nightlies how stable?

Hello all...
My boyfriend has the S4 for AT&T and loves the setup I have on my S3 with CM11 nightlies. Just curious as to how stable they are for the S4. I'm the Android nerd in the relationship and I don't want him to have any issues, since we don't live together.. yet
Or should I put another KK rom I saw over in the development section? Is CM10/JB more stable? How's the battery drain? I want to improve his phone, not give him problems LOL. He's completely stock right now.
I already know how to root and all that, I don't need instructions just advice for the best AOSP ROM/Kernel out there for this device.
Thanks in advance!
Depends on which firmware your boyfriend's phone has. Unless he is on the older firmware 4.2 MDL, there is no way to flash any AOSP rom, custom kernel, or even custom recoveries except Safestrap recovery.
With safestrap recovery, you can only flash certain touchwiz roms.
I'll have to check it out when I see him in a cpl days

Personally...I prefer custom tw roms on this phone..tw is actually better looking and more polished...and alot more features...check out Graviton 1.7

Ktoonsez 01/13/2014 Kernel
I spent a few days messing around with a CM11 1/10 nightly, 1/12 nightly, and the M2 snapshot.
I was really quite impressed with just how smooth everything looked and felt.
Definitely a step up from CM 10.2 and 4.3-based Carbon builds.
I had best results with the 1/12 nightly and the M2 snapshot.
I was experiencing odd reboots and glitches with the 1/10 nightly.
Mine is a pre-MF3 phone, obviously.
rule of thumb with nightlies is that they are not always an indication of an official release. You could get a bad nightly but the nightly before was fine. So far they are fine and nightlies are generally for flash-oholics
Yep. If you're deadset on a relatively hands-free CM11, I think the M2 snapshot is probably the best bet.

OK so I took a screenshot of his system info and sent it to myself LOL
Baseband I337UCUAMDL
Kernel 3.4.0-453947 [email protected] #1
Build Number JDQ39.I337UCUAMDL
Is this the firmware you were referring to? I asked him if he did any system updates and he said he has not.

Yes, that's the right firmware. You can go ahead and use CASUAL, and then flash whatever you like for him.

OK... so all the kerneis are for custom roms... so sad... i like stock rom...
http://forum.xda-developers.com/showthread.php?t=2680948
This is the new stock kernel for 4.4 that let's you flash 4.4 based stock Roms strait from 4.2. You must also flash the baseband when going back and forth. (I think this is what you asked for)
If youre talking about a modified stock kernel for 4.4, then no. No one has anything out yet. And more then likely won't for a bit after all devices have access to 4.4
