Quick kernel question - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I am using foxhound rom with faux kernel now I want to switch to ktweaker kernel. How do I install ktweaker and get rid of faux without having to refresh rom? Thanks for the help

download the appropriate (TW/aosp) KT kernel. wipe cache and dalvik then flash the kernel, fix permissions and reboot.

How do I remove the original kernel from my phone? Just root explore and delete? Thank you so much for the help. I like the faux kernel but my battery life was much better with ktweaker

What are you trying to delete, the actual kernel zip? if so, just use explorer and delete it, as far as removing, it is a matter of flashing a kernel over the existing one.

Ok that's what I was wondering. I know if I just flash the new kernel then I will have two kernels essentially on my phone but then to just go to the faux folder and delete it. I appreciate your help.
I know this is off topic and I will make another Q&A thread if I need to. But with the i9505 rom that I'm using my build. Prop is for the I9505 and somethings like twrp isn't recognising I have an i337. Can I just change my build prop to reflect i337 without any problems with the rom? Thanks for any help

Question between kernal and rom? (newb)

okay, little confused about this whole kernal/rom thing. I flashed the Gingerbread kernal and it shows up in the about phone 2.6.32.33-cm-gingerbread ect.. but then when I flash the CMod 7 nightly ROM(#25) it changes the kernal to CMod. 2.6.32.28(i believe that's it)
so am I suppose to flash the kernal?
U flash the kernal over the Rom, being sure to wipe cache and dalvik cache.

Cyanogen already come pre installed with a kernal. This is why the kernal changed after flashing the Rom.

ALL of the ROMs will have a kernel included into the ROM. They have to for the ROM to work correctly. Look on the development thread for the ROM in question to see which kernel is included and deiced if you want that one or if you want an 3rd party one.
Keep in mind developers use the kernel they included for a reason. If you plan on leaving logs for the developers to advance their ROM i'd highly suggest just sticking with the kernel that is included. some of them even use the 3td party kernels to begin with.
But if the ROM you want doesn't use the kernel you want, yes after flashing a ROM you would flash the kernel that you want. Make sure to wipe the cache and the Dalvik cache prior to flashing the new kernel. AND MAKE SURE TO DO NANDROID BACKUP PRIOR TO FLASHING ANYTHING.

Stock kernel to replace a custom kernel

Hi guys,
Is it possible to replace a custom roms kernel to a original one I've been looking all over this forum for a stock kernel to try but no luck.
Why do i want to do this??
I want to do this as I would like to use sky go app and barlcays apps which detect root and it's driving me nuts wanting to use custom again and I can't because the root is in the kernels. Also is there anyway I can remove them from it

From what rom you want kernel?
You can use a stock kernel in a custom ROM but many of the features of custom ROMs require root access so you would lose functionality.
Your best bet is to flash custom firmware in my opinion.
If only there was a way to decompile the Skygo .APK so it didnt check for root access........

Quick Question About PA

Hi there, I'm kind of new to this and I really want to flash Paranoid android on my phone
I want to ask if I need to update my kernel to do this otherwise it would mess up my phone (that's what I read somewhere)
If so which one/where would I find how to find out.
Thanks!

Just flash PA it has a kernel included. Simply go into recovery, wipe everything but the sd card. Then install PA and then install Gapps and your done.
Most kernels no matter what will work on any ROM with the same version of android. Lets say stock 4.2.2 kernel can work on almost any 4.2.2 custom rom.
It won't mess up your phone. Just make sure to make a backup. Paranoid Android uses stock kernel. If you are coming from 4.2.1 then u will need to update ur baseband first. If you are on 4.2.2; u should be fine; you can go ahead and flash it.

Thanks for the quick reply! I think I'm ready to flash the ROM. Hopefully I won't break my phone!

just keep a nandroid backup.... and after flashing, u can use a different kernel..... im using franco kernel.... u can try that to imrpove ur battery life and it has many other customization options..... or install franco updater, it flashes the kernel easily and automatically......

You have to use a kernel that has these features like the agat kernel or ktoonez.. No stock kernel has this

Issue solved please close

Hey guys I just rooted and installed a few custom ROMs on my n4. When I install a custom 4.3 kernel on any 4.3 ROM I get ridiculous flickering issues. It never happened on stock and only happens on custom ROMs when flashing another kernel. Am I missing something obvious? I have searched for an answer but have come up empty. Any help would be appreciated cuz I really would like to run Franco or faux ( my two favs from my Gnex days). Thanks a lot guys
Edit: sorry I meant to put this in q and a mods feel free to move

Flash the proper kernel for you ROM hint there are two different builds for 4.3
Sent from my Nexus 4 using xda premium
I did flash the correct kernel. At least I think I'm running cm 4.3 (jss15j) and I tried flashing faux's latest 4.3 kernel. If that is for some reason incorrect which faux or Franco would u recommend?
Edit. Ahh I see what u mean by two different builds. Thanks I thought there was only one build on 4.3
