hi guys.
i'm using an insecure kernel and setCPU currently. i'm trying to experiment which kernel or overclock app would be better on conserving battery life (btw, i have a sgsII, and i really want to underclock it for prolonged batt life )
i saw cognition and darky somewhere in the threads. i would like to try them out. i have a few questions:
1) should i flash back the stock kernel before i flash either cognition or darky (or any other custom kernel at that matter)? or i could just flash them directly over the insecure kernel?
2) i used superoneclick root. should i uninstall it or something before i flash the darky or cognition?
3) can install overclock apps like tegrak or setCPU when i use darky or cognition?
Darky and Cognition are full rom's (not only kernel). You don't have to go back to stock.
I would flash cognition 1.20 with CWM and then underclock with setCPU. Best values for battery life.

thanks for replying. i have follow-up questions if your don't mind. i'm new to all of this tweaking stuff.
1) does clockwork mod function like odin (in which i will use CWM instead of odin to flash cognition or darky)?
2) you said darky or cognition were full roms. are they rooted automatically, or i should use superoneclick to root my phone after flashing either one of them?

No but if a rom is made in CWM flash able format then yes.

Read the instruction for the rom it says its rooted or not .
Cognition is rooted but you may need to a have CWM 4 on your phone and easy way to get that is with CWM and root kernel .

Hi All,
I bought my SGS 2 yesterday and flashed it today so I'm entirely new to this phone but not entirely new to Android because I had a Nexus S before.
My questions are:
1. At the moment what is the best kernel for performance, stability and good battery life while being secure (I don't want the triangle during boot) and supporting CWM?
2. Will my root remain with any kernel that I flash?
Thanks,
1) respect forum rules (cluttering forum)
2) read sticky posts (you don't have coded/modded anything)
3) wrong forum (this goes in Q&A forum)
4) read the relevant thread and learn from them

You've been on the forums since 2007 and you still don't know where you should post a question? This is Android Development not Question. Theres different sub-forum for a reason.
1) At the moment Tegrak would be the best performance since your able to control your GPU clock speed as well as overclocking the CPU. The best battery life would (personal preference) be Cognition own kernal built for his own ROM.
To get rid of the triangle flash it using CWMManager (APK), you just get the zImage out of the kernal file put it on your sd card go to CWMManager app and select flash kernal then select zImage. Although you first would have to Flash a custom-kernal with CWM to flash a rom, use odin to flash stock kernal and then use CWMManager to flash the kernal, this will get rid of the annoying triangle.
2) Yes.
Press thanks if I helped
I would recommend that you use the cf-root kernels they are quit good.
As far as I know are there at the moment no special kernels with uv or other cool features. Most of them are quite similar.
I try at the moment the Jame Bond kernel because I know this one from the Nexus S but just flashed 5 min ago so can't give any informations.
Because of the triangle when you flashed the cf-root kernel then boot once with it
go back to download mode and flash the stock kernel of your choice.
I don't know if it works with other kernels but fore sure with cf.
The best thing would be if you don't care about the triangle is too much work if you always try to remove it after you flashed something.

wrong. Lulz Kernels (Tegrak) for example.
Thanks to everyone for the answers!
hi i am on literom 1.5 can i flash the new Ninphetamine-2.0.5 kernal or do i have to update litepro to newest 5.0 thanks ,i have searched but no luck thx
Yes, you can!
But why do you not upgrade to LT rom 5.0, or even 4.?
because all my tweaks blue themes ect all set up
xda app sgs2, thank me if i helped
is that mean yes or no
xda app sgs2, thank me if i helped
It's a yes
ninphetamine seems to work with every rom
thx badwoly it worked
xda app sgs2, thank me if i helped
don't flame me but can i install this through either Odin (just using the kernel on PDA) or CWM (flash a kernel) from /sdcard on top of my stock KG3 ROM? nothing else required?

easy enough. is there any advantage using this kernel with a villain or litening rom? or would just the stock suffice?

I believe both those ROMs come with Ninphetamine 2.0.4 and will likely be updated shortly to 2.0.5. The advantage I find (I am on stock ROM) is that battery life is improved greatly and I can overclock and undervolt using setCPU. I actually underclock and undervolt the majority of the time and get twice the battery life I did running completely stock. For instance 800MHz is plenty for all the HD games I play, I usually run them on 1000MHz when I'm playing them online for less lag (like Order and Chaos).
It's a great kernel that why you'll find it included with a lot of ROMs coming out.
So, by adding 2.0.5 to either ROMs you're just getting the small battery life update which I have yet to see in action. But since 2.0.2 my battery life has been superb.
Enjoy.

Wow. Great answer. Thanks. I'm not really looking to do custom ROM. I just want to flash this kernel with the stock ROM. I'll have to do a lot more research before I can even begin understanding your explanation on underclocking and undervolting. I guess the setCPU comes with this kernel and I can just open it up and adjust values as I wish?
But even before that, I need a little direction before flashing my first kernel via CWM.
Is this how it goes?
- download ZIP file from his thread
- copy .zip to \sdcard (not in any of its subfolders)
- open CWM
- ** now here is where I'm lost. do I either:
- Reboot -> ClockWorkMod
- Reboot -> Download mode
- Kernel -> Flash kernel
and then where do I go from here?
Another question about this kernel
Hello,
I just have a little question about this kernel.
Is it normal that the /system part is mounted as rw when the system start (not set as ro in the init.rc) ?
Thanks

yes just download kernal go to cwm and then goto flash kernal it will reboot itsself and flash kernal fir u did on my 1.5 lightrom

I've been doing this whole "reading" thing about flashing and all that, but some confusion is still there.
I have rooted my newly got SGS2 (i9100, UK).
Now what ? I'm looking at Darky's rom, but there are two files to flash separately: kernel (darkcore1.7) and ROM itself.
1. I was just wondering what is kernel in this situation ? Can i keep my current kernel, which was flashed by superoneclick(2.1.1) or do i absolutely need to flash darkcore ?
2. Same question applies to any other rom out there - can i use different kernel to the rom i may want to flash ? A lot of them come in sets (rom+kernel)
3. Another question - if i mess up kernel flash somehow, does that kill "download mode" of the phone (voldn+pwr)?
I have SGS1 flashed just another day, due to it being "expendable" now that i have SGS2, so jumped in and flashed it following instructions, but without solid understanding. Either stuff gets too complicated or i'm getting too old for this **** (I do have a background of messing with PCs, videogame consoles (ps1 era to ps3/360), winmo6 phones, gadgetry in general...engineer at heart )
You can use any kernel with any ROM. And no I don't think your Download Mode will be gone if you mess up a Kernel.
Kernel don't come in sets. You can choose your favorite there. See Dev section for more details.
Regards.
Correction: SuperCore, not darkcore...
Can i use cwm app (v2.0)to flash any kernels ? Or does it have to be odin ?

Rom>>That depends upon the instructions as always in the rom you choose for a custom rom .
Kernel is flashed via Odin Via CWM app or via CWM recovery .
Kernel is the core of the system between hardware and operating .

Ok, so saying that, What stock Kernel can I use for Cyanogenmod7 ROM?
I was using "XWKE7" previously.
The ZIP file that i downloaded actually replaced my kernel with its own.
I'm asking this as I wanna use Tegrak overclock which is only compatible with stock kernels.

Stock kernels will not work with cyanogenmod. There are no overclockable kernels available for it yet.

Hello everyone, I've decided to root my gs2, and I'm currently undecided between these two methods:
http://forum.xda-developers.com/showthread.php?t=1320350
http://forum.xda-developers.com/showthread.php?t=1103399
The first method (at least for me):
+: is easier to do for an android noob
+: doesn't increment the counter, nor places the warning ! at the boot
-: doesn't install CWM, which I might use to say install the battery mod to show the %
One last question, if I go with CF-ROOT to do my first rooting experience, then say I move to Speedmod kernel, is it doable or it might cause issues? What about reverting from Speedmod to CF?
Thanks as always,
TD
It's impossible for anyone to say what is best for you, but since you then go on to say you ant CWM, surely it makes sense to go down the CF-Root route. It's not difficult to open a program, select a file and click start.
There's no problem changing kernel, so long as you read the instructions on how to flash properly.
It's true that it's not possible to say which one will suit you best, but for me it is Ninphetamine 2.1.3 with Stock XWKJ1, Undervolted with SetCPU.
Giving you root access if just a part of the kernel. So if you flash any rooted kernel that's all you need. Cf-root kernel is as close to stock as possible except its rooted. You can also flash the many other rooted kernels, my favorite is Siyahkernel, it offers the most functionality and gives you pretty much every governor and scheduler out there with NTFS support and much more.
Once you flash a rooted kernel (which typically gives you cwm as part of the kernel) you can from that point on flash other kernels that are also rooted, using cwm. You will no longer need odin.

Hi,
I recently bought Samsung Galaxy S II I9100 on ebay. After receiving it I realized that it has a custom ROM installed on it. Now I cannot update my Galaxy SII using Kies. So, I decided why not flash it to stock ICS firmware.
as fas as I understand I need to flash my phone using ODIN with a stock ICS firmware (I choose the first one from Nordic countries from http://forum.xda-developers.com/showthread.php?t=1544487 ).
Now what if I think of rooting it ? I mean I want to unlock super user privileges. As far as I understand I choose SiyahKernel v3.2.7.2 (from http://www.gokhanmoral.com/gm/). Just like the way I flashed using ODIN. I repeat it with this .tar file from SiyahKernel v3.2.7.2. Is that it ?
Can anyone verify it ?
Yes, but you should flash CF-Root kernel first (after flashing stock ROM).
If not satisfied with this, then you can try Siyah...
thanks for your reply. What is the difference between Chain Fire and Siyah ? I tried to look for differences ... couldn't find any .. CyanogenMod has a lot of documentation... in fact it is kinda scary (with some of its security problems)..

hey ma8 first try to understand everything about root and recovery then try to implement the same
ps- also for rooting ur phone after flashing stock ics rom please check the link below

There is almost no visible diffrences between kernels. at least in normal mode.(siyah has its own CWM, way better than other CWM versions).
Siyah Kernel eliminates some of logging processes and unusefull procedures of android, so it gives you better battery life. specially in idle mode.(about 1 percent for 7-8 hour) and I feel CF-kernels are more battery consuming than stock kernels.
Also Siyah gives you advanced control over hardware, and has a dual boot option.(two different ROM of same version. both ICS or both GB). for best results you should download EX Tweaks from market.

CF-Root kernel from Chainfire is only a rooted stock kernel with a few extras (such as SuperSU, BusyBox, CWM recovery, CWM Manager app, etc.).
Have a look at CF-Root thread for detailed information => http://forum.xda-developers.com/showthread.php?t=1103399&highlight=CF+Root
SiyahKernel from gokhanmoral is completely different, as it is a custom kernel with a lot of patched, parts from other kernels/linux sources/other phones/individually developed code/etc.
See corresponding thread for further information => http://forum.xda-developers.com/showthread.php?t=1555259
If you want to stay "stock" but rooted, then flash the corresponding CF-Root kernel for your stock ROM.
Happy flashing !
P.S.: Use TriangleAway app from Chainfire to remove the yellow triangle and reset the counter after flashing an insecure kernel, such as CF-Root or Siyah.
And as soon as your phone is rooted, you can use Mobile Odin app from Chainfire to flash stock ROMs, kernels and other part of the firmware with an on-device app - without the yellow triangle and without increasing the counter.
CF kernels are STOCK kernels, only with root access.
Syiah, Speedmod and others are developed as new kernels with special properties - adjustable voltage and over- under- clocking... also there is a greater risk of them being unstable
all of this makes me scared .. but, I want to take that leap ... sounds geeky to me..
As long as you understand the process of whatever you're going to do to your phone & follow instructions to the letter you should be fine.
If you don't understand exactly what it is you're going to do to your phone, don't do anything until you do.
