Change kernel on stock ROM - Galaxy Ace S5830 General

So, I installed stock 2.3.3 KPW, the newest firmware. I suppose that my phone would work better if I installed a new kernel. Can anyone tell me how to do it and can I even do it on KPW? I read about CF-ROOT but it's a little complicated.

Complicated or not, cfroot is the only custom kernel we had for now. If u already read about it u should already know howto install it.

But KPW works just fine with stock kernel. Anyway, you can flash CF-root if you want without any problems.

I just did and it all went fine. Converted to ext4 and voila, its faster and now I have BLN. I got almost 1600 in quadrant(which is of course irrelevant).

i thought u can use cwm to install stock rom back...am i wrong?

I'm not sure if you can install it with the stock recovery because I use the ClockworkMod. You should just get Rom Manager from the market and flash it. It's simple. For Ext2 you can use it on a stock kernel fine with OCLF in the market. For Voodoo (Ext4) you need to flash a kernel that comes with it on a Rom that supports it. Like Bionix.

Whoops. Learn something new everyday. It didn't work for me on stock JI6 though, so I figured you needed a compatible ROM.

Then don't use rom manager, flash straight from cwm recovery.

Well yes, but you asked why flash that kernel, and that's why.
Unless you have a version number fetish and want cwmv5!
When I said, works well with cm7, i ment works well with rom manager to install cm7

What I did was flash the codeworkx kernel with Odin (I was using cf root previously) and then flash CM/ from the new clockworkmod recovery I got. I didn0t have any problems, but you have to do a full wipe and I suggest you format \system also.

Oh, then it seems to be more complicated. Have you tried to flash 4.0.3?
What process did you use to flash LPT?

now i flashed siyah 4 and i installed CM9 from CWM and all ok now
but i want to use this rom i will try to flash it again
is it safe?
Yes LPT is safe I'm on a modified version of it right now. It's not the ROM but the kernal that is the problem with certain 4.0.4 leaked ROMs. If you use siyah as your kernel you will be safe.

You're device is fine. I have the same thing and I've flashed hundreds of times. You just have to know what you're flashing and understand the basics

I am familiar with flashing. I had the LG Optimus LTE before this and flashed quite a few roms, This phone however has me awfully confused. I have been researching all day. And so far i am under the understanding that the touch cwm are not good and the use the 4.0.1.5 recovery. But what i don't understand is how do you install roms without wiping data/factory reset through cwm? don't most roms require this? and isn't that what causes the superbrick? Sorry for sounding like a noob. but can you tell me how you do your flashing?

Just use a different kernel, like siyah (www.gokhanmoral.com and make it's for the s2 not s3). Then you can wipe data. Just didn't not be on 4.0.4, and have a samsung based kernel (the kernel dev should have info in the op). Once you're on a safe kernel you can flash whatever you want and wipe data.

Yeah, you should be able to flash through Odin. And you can flash back to stock by getting a stock firmware from www.sammobile.com and flash through Odin

Did you wipe data when you installed it? It's usually highly recommended

Yes I wiped data, cache and dalvik cache. Couldn't get into recovery so i just re-flashed my firmware via odin. All is good now and successfully flashed cm9 with no issues. Must have been a bug in the rom.

How do i go back to stock kernel

Hi my friend has sold his phone and needs to get back to stock kernel from siyah 4.1.5. Is this possible without use of pc.
Many thanks

I think you can use mobile ODIN and flash a new firmware there.
Thanks was hoping there was a simpler way as he only just managed to flash a rom. Is it possible to flash a stock kernel through siyah.
Thanks

23732 is right. But to make it more precise - open your stock TAR rom file in mobile odin (all partitons in the app will be filled in). Then clear all of them but kernel. Then flash only the kernel partition. No need to flash anything more to come back to stock kernel.
