Can I flash any kernel? - Galaxy S II Q&A, Help & Troubleshooting

I have a rooted galaxy S2 with a stock 2.3.5 ROM and I want to flash a different kernel. What kernel should I flash and can I flash any kernel?
Thanks.

Yes, you can flash any kernel as long as you are on a Stock ROM.
Now which one you want depends on you, if I were to suggest one it will be SpeedMod by Hardcore. A great Kernel it is.
I love simplicity.

How to know which kernel is correct?
As of now I am using Sensation rom which has Siyah kernel 2.5.2 and I want to flash speedmod kernel or N.E.A.K. Kernel,
N.E.A.K. Kernel only supports sammy roms
I tried to search but I could not find out if Sensation rom is aosp or sammy do you have any idea of it?
also does speedmod kernel support both as nothing it written about it on its thread
Thanks

Normally on the first page of a rom thread you will get a description what is the rom. For example MIUI is well MIUI. Hyperdroid is sammy deodex rom with of course modifications and tweaks in the build to make it better than stock.
Sensation rom is sammy deodex no aosp nothing like that. And when you normally look for an AOSP rom it normally would say it in the heading of the thread anyway.
On the kernel thread it has a guide of what roms the kernel works on and which ones it does not. Siyah works basically with any rom. CM7 to AOSP to sammy deodex. Regarding Simone's kernel which is the NEAK version or something like that it is based on only sammy stock deodex roms and that is mainly the ones in original development and android..just look out for deodex, sammy and stock rom
AS above its all a question of reading the info on the first page of the kernel post .
Plus if it does not work flash another one .
the Neak kernel should be ok been on mine for a few days .
Speedmod likewise ok have used it before .

Thanks everyone for their wonderful help!
I have got one last question
Speedmod kernel says "it is only for Samsung Gingerbread ROMs. It will not work with CyanogenMod or MIUI ROMS!"
does this means it will not work with sensation rom?
Edit: ok looks like the different versions are just the updated ones
But still the question is if it supports sensation rom?

Now, if you look at the VERY FIRST page for SensatioN ROM,, it says:
SensatioN ROM Features:
-Based on Samsung Firmware XWKK5 Android 2.3.6
With all of this information, you should be able to deduce that the Speedmod kernel WILL work with your ROM. If you still don't understand, I'm going to suggest you don't flash anything to your phone, for fear of ending up with a paperweight.
Ok this time I understand everything
I didn't knew that Sammy roms means that the ROM is based on Samsung's stock ROM
Also I thought that speedmod only works on stock ROM so all this things got me confused
But anyways now its all clear

[MOD][UPDATE] XXLPH/XXLPJ/XXLPQ I777 Kernels - Stock and Siyah+My UPDATE MIUI Kernel

I didn't want to have this get lost in my other threads so I decided to make a new one.
These kernel's have the necessary in-call patch to work for our phones. I have attached a flashable zip so you can flash the I9100 ROM (Only for LPH based ROMs) of your choice and then flash this kernel.
LPQ for MIUIv4 2.3.23 - With NO Screen on/off bug (GO THANK ENTROPY FOR SHARING THE SCREEN ON/OFF BUG FIX)

Steps
1. Do usual wipes
2. Flash a I9100 ROM that is LPH based (pretty sure it is only Sammy based ROM's right now)
3. Flash my kernel.
4. Flash a Modem from our I777 collection.
4. Reboot.
LPQ ROM's verified working on with LPQ kernel
1. CriskeloServanTeam V05
Sammy ROM's verified working on with stock kernel (Thanks cjsabaki)
1. Wanam lite ics rom (has a phone apk with no noise suppression)
2. ICS resurection (It is flawless, has everything working, including: camera, video, usb, external_sd)
AOSP ROM's verified working on with Siyah kernel (Thanks cjsabaki)
1. MIUI v4
2. CM9
3. AOKP Hydro1.5 ROM
4. Bezke's AOKP build
This does not fix the in-call Noise Suppression issue, that is a modification to Phone.apk so be forewarned
Click "Thanks" if you like what you see or donate with my link.
See Entropy's thread/links here that showed me the way to getting the kernel to work on our phone:

Ok thanks, I'm staying on AOKP for now
gonna try this out
I'm gonna try this out but want to make sure I flash the correct modem. Where do I get the KJ4 modem that will work for LPH releases? I've found the Modem post in the original development section and the CM9 modems that task650 posted in the CM9 i777 post. I'd appreciate anybody's proper guidance.
I tried Siyah's ICS 3.0alpha3 for just testing fun last night (knowing calls won't work - just playing), and it had a much smoother scrolling/UI screen feel to it. Would it be possible for you (ktoonsez) to combine / share your collected mods on getting the ICS kernel to work on our i777 phones with gokhanmoral, so he could offer up a Siyah version for our phones? Just wondering... thanks... appreciate all you do for us man!

Take your preferred modem from here : http://forum.xda-developers.com/showthread.php?t=1361393
Then follow op instructions. Basically, Wipe data, flash ICS LPH rom of your choice, flash gapps, flash this kernel, flash your modem, reboot
FYI, I flashed Westcrip's rom earlier this morning using the above mentioned flashing process without issue. I actually prefer Bezke's AOKP look and feel so I went back

Yes I can hack his kernel so it will work with ours. Looks like he is on alpha 4 now. Does anyone know how to contact him, probably should contact him before doing it?
EDIT:
Whihk ROM or ROM's did you use it on?
Also be aware, since there are no sources yet (direct quote from his site):
Warning: this is not a compiled kernel but only a repack of cfroot kernel. only initramfs part is modified until the sources are out.

Thanks that would be cool if you two could collaborate. I am currently on latest AOKP rom. Alpha 4 (whatever is most current) would be the one to integrate. I am happy to test before you release - just pm me the details. Thanks!

Tried Resurrection and Wanam as well as Cm9 and aokp. I liked the cm9 and akop but no adobe flash support. That's a must for me.
I'm back to Wanam now, it seemed more stable than Resurrection. It's been fun playing with these. Thanks to you guys that have made this possible.
I'll see how this does on battery over the long run now.

Just want to say thanks for developing and sharing this. I've been experimenting with a few different roms today thanks to this kernel. Thanks again.

[Q] should i must have to change the kernel if i change the ROM?

hi guys,
i wanna ask you senious guys that,should i have to change the kernel each time if i want to change the ROM of my galaxy s II or any kernel will work with any ROM?
kindly assist me in this matter.thanks.
What type of Rom are you trying to flash?
Most custom roms include a kernel so you you will have to refresh back to your preferred kernel.
Or you can open the zip file and replace the kernel of your choice as long as it matches your firmware version, ie GB kernel for a GB rom etc.

any kernel may not work with any ROMs...almost all samsung firmware versions has got its own versions of Kernel.
In SGS2 normaly custom kernels are used for rooting your phone, like CF-root, whcih are made for almost all the samsung firamware matched kernels, you only want to pick the one matching for your ROM.
It is also seen sometimes advised to back up your Kernel, this can be done using a tool from Market called "Ktool", at a worst scenario, when your installed custom kernel giving you a treble you can restore the previous one.
EDIT : you are already on a custom ROM as well as Custom Kernel. both have got their newer versions alredy.
checkrom is now on V6, and Siyah kernel is now on v2.6.14
Well your still on gingerbread and an early kernel and early checkrom. There are many roms and kernels you can try the best for battery life us what works best for you and only you can figure that out with testing.
Try out an ICS Rom if you haven't done so already and there are now custom kernels for that as well.

I meant the kernel that is already included with the rom when you flash it. So just flash the rom and you don't need to install another kernel after it.
Here is a link to the Resurrection rom:
http://forum.xda-developers.com/showthread.php?t=1436854
Hope this helped you
If you flash a rom it replaces the kernel you've been using with that of the rom you're flashing...
Soooo
Eg cm9 + siyah
If you flash a new nightly it'll replace siyah with cm9s kernel so you have to flash siyah each time.
Think that makes sense..!

You wouldn't get Samsung's OTA updates on any custom kernel. You could try any of the ICS custom kernels. Siyah, Dorimanx, DreamKernel etc..just some of them that come to mind. The best depends on your particular requirements and preferences.

Arent we all, mate..aren't we all. If there was a 'one size fits all' kernel, we'd all be using just that. Unfortunately that's not how it works. Different kernels seem to suit different people. Subjective opinion, I'd go for siyah. Though I know people get a lotta performance outta dorimanx and it has even more tweaks than siyah does. Look around, try a couple for yourself each for a few days or so and then see which one you find best for you.
Good luck.
Hit thanks if it helps.

If the ROM you're looking for is an ICS or JB without the new mali drivers, install siyah for S2 v4.1.5 from www.gokhanmoral.com
If its one of the newer JB custom ROMs with the latest Mali drivers, siyah doesn't support it yet and so you can install dorimanx from here http://forum.xda-developers.com/showthread.php?p=32642159
