I was thinking about installing a new kernel on my KF capable of OC but wanted to have the Stock Kernel before doing anything in case I want to return to stock. Can anyone direct me towards it? I tried looking around for it in the dev section but was not able to find it.
Thanks.

Just make a backup, that way you can restore your stock setup(kernel) if needed.
Yea I created a back up already. So when you restore it also restores the kernel? I didn't know that thanks!

You can also just wipe cache and dalvik and flash your rom over itself and get everything back to stock except your data(apps & settings)

I flashed CM9 but don't really like it - is there any way to restore back to Rogers default settings? Does anyone have a ROM for the default factory settings?

did you not make a nand. backup????
You should when you took a nandroid backup. Something that should always be done just for cases like this.
If not then sammobile.com should have your stock ROM to flash.

Hi, I am a recent iPhone convert thanks to the Nexus 4. So obviously I am new to rooting, custom ROMS, and custom kernels. I am currently rooted and am running a recent CM 10.1 nightly. However, battery life isn't all that great.
A friend of mine told me that a custom kernel can drastically improve battery life without hurting performance. So here I am hoping that someone can help me. Can anyone recommend a good kernel that will improve battery life without hurting speed?
Also, what are the steps for installing a custom kernel? What about going back to stock in case I have to send my phone in for an RMA or something like that? Is that easy to do?
Thanks in advance for the help!
Try Franco or Harsh or trinity .
Custom kernels are more about under clocking a few things here and there to get best balance between performance and battery life thats and some tweaks which are generally inbuilt .
But tbh not all phone's are same what works for me and few others might not fetch u the same results, i've experienced this over my previous nexus device .
Some combo of ROM/kernel might work for u and not so well for other's i would say try out all the main stream kernels and some more if your'e feeling epxerimental give each kernel 2 to 5 days and see which u like the best.
Personally i've had good results with harsh kernel and franco and trinity .

Do you have one that you would suggest for a first time newbie? Also, what is the process for installing it and potentially uninstalling it back to stock?
Everything is easy to do. AS LONG AS YOU READ FIRST before doing anything You can start by reading the guides found here in the Nexus 4 General thread.
So far, the best for both performance and battery for me is Trinity kernel.
By the way, to install a custom kernel:
1. Install proper drivers for nexus 4 in your pc.
2. Unlock your bootloader.
3. Install custom recovery like CWM or TWRP Recovery
4. Start flashing your choice of kernels!

Thanks for the advice! I am currently using CWM and have an unlocked boot loader. Is it as simple as downloading a zip, going into recovery, and installing the zip from "sd card"? If so, where can I find the zip for trinity? And how can I go back to stock in case something goes wrong?
There are post on xda and you could Google it. Just download it on your nexus and flash it

If you want to be always safe and sure, then BEFORE flashing anything, go to CWM, choose backup and restore, then choose backup. That is called a nandroid backup. It might take a long time depending on how much apps you have. After the nandroid backup takes place, then you're free to flash the zip for trinity that you've downloaded.
I also suggest that you do backups often and delete old ones (you can delete old backups in the "backups and restore" part of CWM). So that incase anything goes wrong when you flash something, just go back to recovery mode, then restore your latest backup and you can undo your wrongs

nandroid backs up everything. it basically takes a snapshot of the state your device is in when you back it up, then restored your phone to exactly how it was before the backup.
Coming from HTC One S (and a whole lot of HTC family before that) and not having to deal with S-Off dilemma is a whole new free world for me (you can say i am institutionalized).
If I want to flash a rom and not the kernel included in it, can I just remove the boot.img file from the rom's zip and flash it? Or is that not a good idea?

no. you need to flash the whole zip. without a kernel, your device is an expensive brick. the kernel control pretty much everything and connects the hardware to the software. you can always flash another kernel after flashing the rom zip.

all nexus 4 kernels are compatible with all nexus 4 roms. if you flash a non nexus 4 kernel onto your nexus, you will most likely brick it.
Sounds great. This will be my first Nexus experience. Love this forum already. A very mature crowd.
Does anyone know of a stock flashable ROM without Root and Busybox?
I'm aware of the thread guiding people on going back to factory but I don't want to do that. I want to be able to just flash a Rooted ROM if I want one and flash back to standard unrooted if I want using TWRP.
My reason behind this that I spend a lot of time on the train at the minute so decided to get Sky Go. Unfortunately it detects that the device is rooted and won't run.
There are a few threads around the net with scripts and suggestions but nothing seems to work for me.
I don't think there are any..... Hmmm.

You can flash the stock ROM with fastboot but not from within recovery. Get it here: https://developers.google.com/android/nexus/images

If you could do that it would be great.
I was just looking at the tutorial to bake it myself but having issues with Cygwin. Much quicker and easier if you did it.
Owe you one.
I use Linux so it won't take long. You literally want a flashable stock ROM, no changes whatsoever?

Exactly. I use a standard stock rooted ROM usually.
Just realised I don't actually use root for anything at the minute but likely will do in the future.
Thanks again.
I'll try and do it this afternoon but if not this evening once back at home
Uploading at the mo, it's literally the stock ROM dumped into the kitchen and cooked out with no change whatsoever

Very cool that you've done this, but I should give a word of caution: there are some problems that wiping via fastboot will fix, but installing a flashable stock .zip won't fix. For example, when a 16GB phone thinks it's only 8GB. (I have reason to believe that there are other problems that can only be fixed in this way, but I can't prove it. :silly
That's not something the OP cared about, he just needed to 'unroot' to use a TV app that checks for root access

I tried that.
I tried a script that was published on the net to remove root and busybox.
I tried removing root and busybox manually.
I tried flashing stock kernal
I tried several other apps.
A flashable stock rom was my last resort as I was under the impression that I'd need to wipe and I didn't want to do that. I just tried it without wiping on the off chance that it worked and it did, so problem solved.
None of my Apps were using Root so I thought I'd get rid of it completely but wanted the option to flash CM10.1 once Bluetooth MAP profile is fixed and working without having to go through putting TWRP on again.
It's all in the OP and posts following that.
EddyOS saw what I was after and offered to help. He's a great dude.
Just for learning purposes, how come no one has made a flashable stock zip until now? Wouldn't it just be like any custom rom but instead its just stock?
Is there not a recovery for the Galaxy s4 yet on Sprint. I was able to root my phone on a mac but I was not able to get a recovery "cwm or twrp". If there is a way to get it on my phone via mac please let me know so i can reroot my pone.(unrooted because without recovery i could not flash a rom)

You should probably take a look around. It's a few touches away.
Sent from my SPH-L720 using xda app-developers app
Have you tried installing one using your phone?
There is custom recoveries available. go to the Android Development forum and go to Shabbypenguins OUHDS recovery thread, and it provides excellent instructions on installing the recovery and then on installing root on it. Then your ready to go to flash roms. Right now Unknownforce's Force Rom is the only TW rom, and Slim bean is the only AOSP rom in beta - though alpha builds for CM, PA, and AOKP are currently being worked on by a great dev and should be up and running soon enough!
EDIT: CM is actually in Beta as well at the moment!
And personally I have never had a mac, nor nothing anything about the limitations of using a mac using these methods, so you should definitely look into it if it is different at all.

I am not completely sure, but doesn't Autorec install the stock kernel (patched only for loki etc).
Thread title asks just for the Stock Kernel and since you have already a custom recovery , you would need a patched kernel. Doesnt have to be Dorimax.
Or really completely stock with everything and unroot?
Oh, I'm sorry. I meant I want things to go back the way they were - stock 4.4.2, stock kernel, no custom recovery. Is it even possible without a complete reinstall and wipe?

when installing a new kernel you should never judge by one day, you should always allow 2-3 days for everything to fall in place, saying the above is like installing a new rom and if in few hours its draining fast you blame the rom but in reality you didn't give things a chance to fall in place and run as they are supposed to

well naturally for flashing a kernel you wipe dalvik/cache and I mentioned earlier if you want to go back to stock you would need to use back to stock guide which will erase everything on your phone so backup anything important
