How to install a different kernel?

I'm surprised not to see a topic on this in the SGT Bible. I've just flashed Overcome ROM, and I see a lot of recommendations for pairing this with koxudaxi kernel.
What's the procedure for keeping my current system and changing kernels? Do I just drop the koxudaxi kernel zip in my internal SD root and then flash that zip from CWM, or are there any gotchas I need to watch out for?

Easy to flash another kernel and its more easy to brick your tab, you should know what you're flashing and see if it can work with your system or no

I agree 100 percent with k0sh on this. Each kernel(or ROM) usually come with an instruction on how to install and also some precautions. These should be followed to the letter.
As for the bible-I also agree that it should be updated.

Yup, so I know what I'm flashing (koxudaxi kernel), and it works with my system (an AT&T GSM tab).

Unfortunately, there don't seem to be any instructions in the koxudaxi kernel thread on how to flash it. So what's the safe way to apply something like this?
Edit: Okay, I just went ahead and did it, and for anyone following along, yes, you just choose flash from zip in Clockworkmod.

He gives two formats of the kernal. The .tar file is for heimdal or odin. The .zip is for flashing with CWM.
I have two tabs. T-mobile overcome 2.0 koxu kernal. At&t with stock gb. Chainfire kernal for root and CWM, koxu kernal for tweaks.

[Q] Ext4 to RFS on the Tab

Hello Everyone,
First of all, let me thank everyone on this forum, because it's an endless source of information regarding our favorite gadgets. I'm pretty new to this so please forgive me if this is too basic.
I've searched the forum but couldn't find a clear answer to this. Here's my background:
I have an Euro Tab, and had a few updates via Kies, first to JJ7/JK5/JJ5 (CPW) and then to JMI/JMA/JM2 (CPW).
I rooted with z4root and then with SuperOneClick (on JMI, as z4 wouldn't work). I was a bit afraid of trying custom roms, but finally took the plunge because I was tired of waiting for official Samsung Gingerbread.
I started by patching the bootloaders on JMI, as instructed in the forum and flashed JQ1. I had a few problems, but I was able to solve everything and get GB running and then rooted with CF-Root
Of course, this is like an addiction and less than 24 hours after that, I flashed Overcome Hermes 2.0.1 with 3.1.0 Kernel, adjusted UV settings and installed a few Mods.
This is like having a new tab. it's responsive, battery is better and apart from a few minor bugs, it's really the greatest experience. Congrats to all the devs. This is what it should have been out of the box.
As I understand, OC Hermes 2.0.1 converted the file system to EXT4 while partitioning (please call me wrong if this is not true). On a friend's Galaxy S, he has the option to convert to EXT4 and revert to RFS on the CWM app which doesn't exist on OC Hermes (again, please correct me if I'm wrong).
Now the question(s). (finally) If I ever want to go back to stock (Froyo) either to try the official Samsung GB for my region when it comes out or if I have to send it to Samsung for some reason (knock on wood), can I just use Odin and flash a stock ROM (say JMI) with repartitioning with no problems or do I have to revert to RFS and then flash Froyo?
If so, how should I proceed to go back to RFS?
How can I confirm which file system it's using?
I've seen threads talking about going from Froyo to GB and back, but never with overcome, always with stock ROMs so, to avoid problems, I decided to ask this for a straight yes or no.
Thanks in advance for any help or comment. If this has been answered before, please link me to it. As I said, I couldn't find it through search.
Best, a.

I use chainfire's ext4conversion tool. It has the ability to switch to rfs. I am not on overcome rom so not sure it will work but its an apk available on xda forums, could give it a whirl.
As for the tool it works good.
Reverting to stock will get u back to rfs as well. (from memory stock gb files from overcome 2.0 rc1 were ok / going back to froyo had to use one of roto rom froyo versions ).

Thank you. It's amazing that just by searching what you referred in your post, I was able to find a lot more info on this.
For what I understand, Overcome is based on JPZ and there's no CF-Root for that. I think the tools apk can be used with CF-Root only, right?
Maybe I can flash JQ1 (or other ROM supported by CF-Root) and then convert to RFS if needed.
Now I need to know if I have to go back to RFS to flash a stock Froyo ROM.
Again, thanks ;-)

If you use odin + re-partition with the pit file then essesntially you are formating back to rfs. So any stock froyo rom will be ok. Cwm flash / update wont work. I suppose you have already have your original firmware or just download one.

That's what I thought, but wasn't sure. Being a noob has it's quircks
Thank you so much.
BTW, CF-Root is basically superuser+CWM+busybox. If I have these on Overcome, is it safe to assume the EXT4 tool extension for CF-Root will work on Overcome or should I expect other dependencies? I think CWM versions are different in OC and CF-Root.

You can basicly back to froyo rom
As about the ext4 to rfs , you can do that for overcome hermes , just go through cwm and then vodo and then disable it from there (lagfix) after you reboot your system will start convert from ext4 back to rfs and also u can do the same if u wanna back to ext4

How much time that conversion usually takes? 5min., 10min?

Depending on how much data you have on your tab. If your internal memory is studded with apps it will take quite a long time (45 minutes was reported) as the system backs up your data then restores it after conversion. If the system has fewer data it will take less (5-10 minutes).

for me last time , around 1hour and my tab didn't boot , so i just force reboot it during the convert and i was know that i have to reflash back , but i take the risk and boot it again and its start over the conversion and it takes 5 to 10 mins

[Q] Help with Boog's KI1/KI2 Kernel

How do I know if Boog's KI1/KI2 Kernel 2 was flashed?
Kernel version says: 2.6.35.7-I897UCKI1-CL607313
init.d folder contains only: S99complete
I have CWM so I'm assuming that Kernel 1 flashed properly through Odin3
I came from S7
flashed AT&T bootloaders and stock KI2
then flashed emunee's rooted/deodexed/zipaligned KI2
then flashed Boog's kernel 1 .tar with odin
now I'm trying to flash Boog's kernel 2 using CWM....
What am I doing wrong? any help would be appreciated

The name of the kernel will not change because no source released yet. Since u have CWM ur doing good. The kernels are flashing for u. No worries.
Sent from i897ucki2

Thanks for all the help, I have 2.3.5 w CWM and i know boog has an updated kernel w root. Should I put that in my sdcard directory and restart in recovery and install package? Would that root me? Thanks, Im pretty new to this and just flashed for the first time and am very happy but wanna get rid of all the ATT crap

Thank you for the prompt attention, what about the init.d folder shouldn't the scripts show up after flashing kernel 2?
Would it be advisable to simply flash U.A.S.?

I think people have been having issues with boog's root kernel actually taking root from them rather then giving them root. I would advise the kernel swap method over flashing boog's rooted kernel for now.

If done correctly in the proper order (kinda difficult not to) only one script should appear in the init.d folder. As for the USAS I recommend reading the link in my sig about Android Optimizations first.

Thank you! For now I will wait a bit, I am using GO launcher so I hid all the ATT stuff.

Root files when using Odin

Hi, I am trying to root my Galaxy S I9000. It is gingerbread.xxjvt 2.3.5, and I am using a tutorial to root.
Now the question is in the files the tutorial provided, there is a file named CF-Root-XX_OXA_JVT-v4.3-CWM3RFS. If I unrar it, there is a file named zlimage. Which file should I use in Odin?
Thanks for any help.

Well don't unrar it, it goes straight as it is in odin. Inside PDA, be careful not to tick re-partion !!!

Odin open and be careful not to re-partition is checked then click on the PDA and put there cf-root or kernel. I suggest if you put everything on the phone root is better kernel semaphore. good luck

Thank you and others for the help. I don't know what you mean in the second part of your post, I don't know much about kernels and stuff. At least now I'll have a rooted phone; one at a time! Roms and kernels are next.

I did not undestand the second part as well but I think he wanted to tell you that you may use the Sepahore-Kernel instead of CF-Root because it has some Modifications in it to capitalize every feature wich a rooted phone can provide you eg. Voodoo-Sound, Bln and so on.

Do you mean that instead of using this file I can use another file in the same way and have a rooted phone with extended features? If yes, does that mean cf-root file is also a kernel?
Sorry, newbie! My lack of english knowledge doesn't help as well.

Download from market sgs flash kernel app, download kernel semaphore 2.4.0 ( serch in google) save kernel on sd card in phone, go to SGS Flash |Kernel and choose kernel (semaphore saved on sdcard)-> flash kernel , than u have nwe kernel semaphore.

Can someone please help me with it?
I'm a beginner...
Please help...

or choose anyone as you like ^_^ >>>>>> http://forum.xda-developers.com/forumdisplay.php?f=665
thanks

Hi there, try XWJW6. Its much better and lag-free already.
Then, you may flash CF Root kernel and convert the filesystem from RFS to EXT4.

Hi - forgive the noob question....it's 2013 and I've got Gingerbread.XWJW8 and find it a bit laggy. I wanted to reflash a custom kernel to address occasional lag. But from above the lagfix is standard. Does this kernel include these anti-lag features? Should I reflash or let it lie.
OBTW, tried to root it using developer mode from a couple of techniques on youtube and it failed. Is this because Samsung blocks it?

nope, flash custom kernel, semaphore or cf root n ur fone will be rooted

Yes the above mentioned kernel includes lagfix.
Samsung doesn't block anything. You are not following the correct method.

Thanks - but may need more help as my phone is in a rebooting cycle now
Downloaded and installed standard Firmware from Sammobile - all good
Followed directions on http://forum.xda-developers.com/showthread.php?t=1044519 and downloaded SpeedMod kernel K16 series which works on older Samsung 2.3.x roms. (mine is 2.3.6 GB). Started Odin3 and installed the .tar and it appeared to flash fine, then rebooted inot a continuous cycle. I followed directions to the letter - what could I have done wrong?
I'll try another older speedmod kernel and see what happens, otherwise it's back to the standard one again.

There shouldn't of been just one .tar, it looks like you may of flashed an update instead of a whole rom.
If there was 3 .tars then you probably put them in the wrong place. Try use a guide off android souls website. They really simple and I used them when I first started.
