hello! you can try a very good kernel by a Chinese , it's so wonderful
with cwm and bln and shutdown phone alarm clock

To fix usual lockups and FC's, you have to wipe your Cache partition and wipe your Dalvik cache from CWM Recovery.
For a good kernel, try Ninphetamine, it comes with CWM 4 and BLN support. Also try another great kernel called Void from http://forum.xda-developers.com/showthread.php?t=1357020

I've tried ninphetamine, but bln never worked. I'm happy with this kernel, do if I clear those caches, them problem solved? Or I really need to change my kernel?

Cm9 9.1.0 flash siyah kernel v4.1.2.

I have a rooted galaxy s2. I have Cm9 + gapps installed with stock Cm9 kernel!
I want to overclock, and I saw the siyah v4.1.2..
I read a lot of forums but I wanna to be a save as possible, and now I am here
My question is!
1. Is it possible to flash this kernel treu cwm?
2. Does the kernel support Cm9 and my galaxy s2 i9100?
3 how to flash is? ( clean dalvic and some other thing, then just install the zip file treu cwm? Is this right?)
4 are there any known problems with this kernel? (working on cm9)
5 what are the risk?
6 last but not least: can I now overclock with siyah v4.1.2. Yes? How much? .
Irrelevant..........
The first time I saw cm9 I thought omg I want to have it. Almost I year later, I found my balls again! I read every post every step and finally I got it rooted ( with Odin insecure kernel that matched mine!) I thought this is the beginning of cm9 "jeej". Then I saw my third ball rolling over the floor! So I downloaded cm9 + gapps put is on my internel sd. First I did wipe data dalvic and all that for 2 times! Then flashed cm9 then gapps! I rebooted and "jeej" I got cm9! I think I got it now for uhm 3 days or so. But there is one last thing I wanna do and then the Storry is compleet. I wanna overclock. I know how to flash but I need to be 99,9% sure (1% you can always **** up) how to do it!
Normally I am not someone who post but read.
Thx in advance

1. Yes, you can flash it via CWM recovery. You must however download the zip format of the kernel.
2. Siyah kernel supports CM9 and GT I9100
3. -boot to CWM recovery
-wipe cache partition
-wipe dalvik cache
-flash kernel
-reboot phone
4. You have to test this yourself, many people here on XDA, are using this kernel with CM9. If you eventually don't like the kernel, you can flash another one.
5. If you follow institutions, there are no risks at all.
6. Siyah kernel supports overclocking up to 1.6GHZ (please check Siyah thread to confirm this).
After flashing Siyah kernel,
- Download EXTWEAKS from playstore.
- this is the official tweak app for Siyah kernel and You can overclock with it.

Sorry, one more question....
I got the app extweak. And I overclock cpu and gpu but system freezes!
When I rebooted, the settings were still very high.
Question: is it possible that when system reboots, that the default settings return? (in extweak)

in case you face problems/bootloops, after using extweaks (wrongly), try this:
-boot to CWM recovery
-kernel specific options
-reset extweaks profile
-remove all files from init.d folder
-reboot phone
Done.

When a new version is out, is it possible to flash over it jusing cwm?
And do I need to wipe dalvic and cach again?

If you are taking about Siyah, then do this, when flashing new version:
-boot to CWM recovery
-wipe cache partition
-wipe dalvik cache
-kernel specific options > Reset extweaks profile (your extweaks settings will be deleted)
-flash kernel
-reboot phone

Thank you, very useful
And what about trying to flash a new kernel from a other dev.
Is it still the same method?

There are two ways:
1. The method above (in my previous post)
2. Download kernel cleaning script here: forum.xda-developers.com/showthread.php?t=1363738
Kernel cleaning script, cleans all the trace of your previous kernel before flashing the new one
-boot to CWM recovery
-flash kernel cleaning script
-flash new kernel
-reboot phone
Note: if your kernel doesn't support extweaks, then you have to uninstall extweaks just before/after flashing the new kernel.

In my experience you can flash a new version of the kernel without wiping anything unless the release notes say otherwise.
In fact the same is generally true of new versions of a ROM (including CM9). The same is not true of different ROMs however, where it's usually recommended to wipe the cache partition, Dalvik cache and all data to avoid boot loops and crashes.

Safest, clean method of flashing anything, ensures best stability & performance with new ROM/kernel
For example, From CM9 instruction page:
Upgrading from earlier version of CyanogenMod 9:
- Copy CM9 ZIP to your internal SDCard
- Boot into Recovery
- Flash CM9 zip
- Wipe cache partition and dalvik-cache
- Reboot

flashing a stock rom with odin on custom rom with dorimanx

Hi,
I downloaded a stock rom from sammobile ( I9100XWLQ2_I9100XXLQ6_I9100PROLP4_HOME.tar.md5 )
I am pretty sure this is the right one because this has already worked once.
But now my phone hangs during startup. I wait really lot (10 mins) but still it hangs, even I always see the animation of 'S'
I flashed again a custom rom now, but i want a stock rom back. How can i flash?
thanks
You must perform a factory reset from the recovery. Either do it from the custom rom, then flash stock ROM, or flash stock rom, boot into recovery and then wipe /data. Order doesn't matter.

After you flash the stock rom go back into download and flash v4 of Siyah kernel (.tar) , then boot into recovery and do wipe/factory reset.
It is not necessary to install a new kernel, just factory reset from stock recovery

I didnt say it was necessary, I just advised it since Siyah kernel is better then stock anyway for many reasons and since he's into trying new roms its much better to have custom kernel/recovery. Plus the fact that if user was to try flashing a 4.0.3 rom then wipe in stock recovery he would brick his device.
Not sure about brick, AFAIK brick occurs with 4.0.4. Anyway I would prefer more stock-ish kernel like CFroot.

If you thought that, why on earth would you advise him to wipe in stock recovery???? The rom he is trying to flash is 4.0.4
Guess I wasn't reading thoroughly .. I take mt words back.

If u r on stock 4.0.4 first change your kernel then try to factory reset.. Everything will be fine... Dont do factory reset on cmw on stock kernel...

Okay, thanks for all the replies. When I flash stock kernel, will clockworkmod be erased? I am just asking.. I know I can easily flash it back

Do you mean flash "stock rom"? Yes if you flash stock rom you will lose cwm and only hav stock recovery.
Once you have flashed your stock rom you should then immediately flash your custom kernel (Like Siyah). Once flashed reboot into recovery (cwm) and wipe data/factory reset.

When flashing a stock ROM (include kernel of course) it overwrite the exists kernel.
Sent from my GT-I9100 using xda app-developers app
When you will flash stock rom over custom rom everything will be erased if android version is different if same then you will face problems has phone will not work properly you have to factory reset it first install different kernel use philz it will root your phone directly and installs cmw then factory reset it from cmw.
You can also reset your phone from settings but in between you will face errors this that not working etc. use 1st method your phone will not have brick bug issue.
And for giving thanks use thank button

Ktoonsez Kernel question?

I'm currently running liquid smooth. Do I just flash the kernel over and wipe cashed and davik; or do I need to do a full wipe then install ROM, Gapps, then kernel?
Thanks in advance!
Sent from my SCH-I545 using xda app-developers app
you only need to install kernel then wipe cache and dalvik and according to ktoonsez instructions fix permissions also.
no need to start all over just to swap kernels

[Q] Switching ROMs

Hello,
sorry if this was asked, but I wanted to know what should I do if I wanted to switch roms? For example from CM 10.2 to CM 10.1, do I need to reflash stock rom, or can I just wipe data and cache in recovery mode and just flash another rom on top of it?
Thanks in advance!
You should be fine with just wiping cache, & dalvik, then flash the Rom.
