Question about kernels

I went through alot updating to 2.3.4 with backup, restore, wiping, etc do I have to go through all that again if I update my kernel? I'd really like to try the voodoo sound but I dont think the hassle is worth it just for sound quality.
Thanks

The minimum you should do is wipe cache and dalvik cache and reboot.
But in case, maybe nandroid before too

If you only want to try the kernel you can use the command
Code:
fastboot boot kernel_boot.img
This will not really install the kernel into your phone. If you don't like the kernel then just reboot, it will revert back to the original kernel.
Once you think this kernel is worth flashing then use the following command to permanently flash the kernel into the phone.
Code:
fastboot flash boot kernel_boot.img

You don't need to wipe anything when replacing the stock kernel with another. Alternatively, you can purchase Voodoo Control Plus and let it load the voodoo module for you. You need root for that however.

got 2 questions for this
1..if i try that "x"kernel and i do install it...will it be possible if i wish to return to stock kernel?
2...trying a kernel with that command you provide is like "virtually" loading it to device?so i can check if f.e. voodoo sound/colour BLN kernels work on my device?
reason i am asking this is that i had a really bad experience when i tried to use Netarchy's / james bond kernel for that BLN function and i could not use it...BLN was not working so i got to the point that i had to un-root/re-lock my device..not 100% sure if i want to start all that over again.....

1) In that case the easiest way is to do a nandroid backup before flashing. Note that some kernels come in a flashable zip file and contains more than just the boot.img (i.e. it also includes wi-fi module, startup scripts, etc.) So if you flashed the zip file, your existing files may got overwritten.
2) Yep, but you may not get all the functionality working in case the kernel requires external modules. The command just loads the kernel itself into the phone. I think Voodoo will work because it is built-in into the kernel, but I'm not sure about BLN, may be it also requires an external module file.

Restoring to stock OS

If I restore to the stock OS, will it replace the Imoseyon 4.0 kernel or will I have to do that manually? I know im going to have to turn off voodoo before doing so, but otherwise im not sure.

If you flash a full stock Odin, it will replace everything, kernel included. If you follow the instructions in the Fix Your Phone thread, it will even repartition everything clean as well, though that's probably not necessary unless you're having boot issues.

New root kernel and tweak - wifi calling not working

Just installed my first kernel "Subtly Modified Stock CWM 5 KJ6 Kernel" and "Lightning Zap" tweak on gingerbreak 2.3.6. While the phone is now moving faster, wifi calling won't connect. And I have very poor signal at home, to the extent that I now can't make calls.
Help Plz
I get w006.15 error in tmobs wifi calling prog

Wipe and reflash everthing and try without the tweaks.

that would be my first bet.
So yeah, remove tweaks.

Do I flash back to stock and reinstall the kernel or is there a way to unistall tweaks?

The cleaner & probably easier option would be flashing back to stock.

You can flash back to KJ6 Stock following the guide in the second link in my signature. You will have CWM to then flash a custom ROM.
Or you can use the Gremlin Remover then flash a custom ROM.

thanks bros

I already have CWM, whats the easiest way to go back to stock?

You can't flash back to stock from CWM. The 2nd link in Lumin's signature points you to the KJ6 One-Click Collection. Go there and select the one-click you want to install (one of them is pure stock). They install pretty easy, just makes sure you read through the OP for them.

If you have cwm this is really close to stock.

[Q] How to remove custom Kernel?

I'd like to remove the trinity Kernel for JellyBean. I enjoy it's overclock but I hate it when my phone just randomly reboots. Is there a way to remove it. I have created a backup before I flashed it, but I'd like to remove it without having to restore to that backup.
Thanks

flash your rom without wiping, then flash gapps

I should have mentioned, I'm running stock. No custom rom installed

Just flash a different custom kernel or the stock kernel. If you want a different custom kernel, and you want something stockish, you wan try SimpleKernel or thalamus kernel. As for the stock, I think you can find a flashable zip somewhere here in the NS forum.

[Q] Flashable Stock Kernel + CWM + Root?

I'm running a stock rom but a blastoff kernel with root and cwm. I would like to go back to a stock kernel, except for root and cwm.
It there a flashable zip kernel which is stock+root+cwm that I can flash from recovery?

There is no such thing. Stock implies it's not touched, no edits, direct from the factory. In order to get root + cwm, it has to be modified and therefore is not stock anymore. Blastoff, Antox's, or any other GB kernel with root + cwm are all based off stock kernel source code with the the root and recovery added in, so what you're asking for you already have, and what you want is a contradiction.

I presume that those 3 have other changes other than root +cwm. I'm looking for a kernel with only the root+cwm change.

There is no such thing, I get what your saying. Most of our modded kernels don't have much difference beyond root+cwm, so there's no reason not to use them
