[Q] Can the kernel affect the performance of the modem? - Galaxy S II Q&A, Help & Troubleshooting

Hello,
I have a SGS2 running CheckROM 3.1.1 (http://checkrom.com/threads/checkrom-revolutionhd-v3-1-1-xwkj3-rock-stable.208/) and trying the SiyahKernel 2.2p (http://www.gokhanmoral.com/gm/2011/11/29/siyahkernel-v2-2p/).
Since a few days... I think it started when I've installed the SiyahKernel from 2.1.1 to 2.2i and then 2.2p... I notice the modem (the Internet connection via my Carrier) goes slower or drops more often.
Also, sometimes, when I reboot the phone, I don't get Internet service or I get service for a few minutes and then drops.
I attach a screencapture of what I have when the connection drops.
So my question is: Could the Kernel affect the MODEM?
Strange? Help?

Not really unless there is something wrong with the kernel .

Considering that SiyahKernel is one of the most popular Kernel...
There is not something wrong in the Kernel.
The problem is my Carrier.

If you think popular means 100% correct dream on .

Jajaja!
But popular means that is tested. Is more tested than what I can test

Generally, the kernel has more interaction and direct effect on WiFi than it does the radio.

So... You are saying that could be a relationship? Small, but something?

It's more than likely the kernel. The modem type you use has a negligible effect on battery life.

Just as JJ mentioned above, not unless there's something wrong with the kernel. The thing to remember when flashing a new kernel is to clear out all the old junk from the previous kernel first.
There's script here to do it, which is a good idea to flash via cwm recovery first.
At the very least, you should manually clear cache and Dalvik.

Is this the mentioned script?: http://forum.xda-developers.com/showpost.php?p=13224453

Which kernel is better ?

Hi,
I realized these 2 leads kernels :
SpeedMod SGS2:
http://forum.xda-developers.com/showthread.php?t=1182498
Ninphetamine-2.0.2
http://forum.xda-developers.com/showthread.php?t=1179814
Which is the best for your opinion and what do you recommend ?
Neither try them both yourself .

Ninphetamine-2.0.2 is the best and optimized kernel for all custom roms....
am using it now...

The best kernel is stock KG3 right now. All those custom kernels are based on outdated KF, since that's the latest released kernel source. None of them solve the Android OS bug either. I tried them all and returned to stock.

Can I install it over Cognition 1.31 ?
Right now I like Lulz-Kernel-Build-11-for-I9100-XXKG3 . Before i used Ninphetamine-2.0.2 it was good also.

Me too. I haven't received any proof, that Ninphetamine is better.
Now I'm trying lulz. 24 hours flight is normal. At least it has better CPU power and clock management.
Ninphetamine is VERY fast, i'm trying to find something fast as it is.
Beside I can use setCPU to customize the clockspeed, I don't see any advantage if using customize kernel.

At least SGSII is already as very fast as you can't get it from it on 100% yet.
By default Ninphetamine uses ondemand CPU Profile. So, I hadn't noticed notable changes in speed with equal settings.
Battery life stayed the same, apropos.

setCPU doesn't provide for you any notable improvement in battery life. Undervolting (UV) does. So, setCPU on Ninphetamine provides UV. But the best way IMHO - is Tegrak Overclock Ultimate - it's capable to change voltage of the Core, Bus and GPU. And of course it works better on author's kernel (lulz - it means tegrak kernel).
Unfortunately, setCPU is not fully compatible with all kernels and vice versa - Tegrak is not compatible with all kernels.
If you recommand the stock KG3 kernel, may you post a link please ? (can't find it).
Thanks.

Its in the stock KG3 firmware .
Download Extract Zimage flash via Odin or CWM .

note many many users confuse kernel with firmware its not the firmware only part of it . the bit that interfaces at the lowest operating level machine code as it where .

Nothing against you or the developer but its 100% placebo effect, The S2 is extremely fast that I doubt even kernel changes would matter or even slightly affect speeds, sure you get over 9000pts in quadrant but no real world increase, w/o the voltage controls you cant tell the custom kernel from the stock kernels apart.. Unlike during the S1 days.

Can you tell me one app or game that runs slow with the stock ROM and kernel? This is a very fast phone anyway. It runs everything very fast right out of the box. No need to go playing with voltages and clock speeds and risking bricking the phone.
These alternative kernels are just for -my quadrant score is bigger than yours- type of users and have no real life improvement over stock.
When I moved from an old stock kernel to Ninphetamine-2.0.2 I saw a big difference with the application invocation speed. Even clicking the keyboard was very smooth and without any delay unlike the old stock one.
Maybe it's because the stock kernel version was older I'm not sure , but this is real.
Try this.

Sorry for the noby question, but the stock KG3 kernel will remove the cwm recovery i got right ? so, if I want it back I will need to flash a custom kernel again ?
Well, just flashed SpeedMod.
Extremely slower than Ninphetamine

Best method to update to gingerbread 2.3.4 ?

Hey guys just got my SGS 2 a few days ago it's on stock gingerbread 2.3.3
I have a few issues:
What's the best method to update to gingerbread 2.3.4? I've heard of Odin..? Any suggestions?
Battery seems crappy - drains very fast
How do I turn off 3G ? Can't seem to find a setting in the phone
1) Head to Intratech's stock ROM thread in the dev section, choose one to your liking and flash via Odin.
2) It's a powerfull phone, so eats lot's of power - but there's ways to tweak it a bit (like disabling not needed background apps/services/craps) and about a million threads about that matter
3) you're talking completely disabling data connection or disabling 3G to only use GPRS/2G? To completely disable, hold power button and choose "Data Network Mode"

1) Thanks
2) Yeah i've read about the Lite'ning rom ? Would that be a good choice?
3) I want GPRS/2G, not completely turning my data connection. How do I do that ?
The ROM a lot a matter of personal taste, but I've heared only good from lighning ROM.
Then try this:
Settings -> Wireless and Networks -> Mobile Networks -> Network Mode
Not sure, but maybe it's what you're looking for.
If not, I'd guess there's a widget for it on the market.
Lite'ning Rom 5.0 seems very stable and awesome so far. Some people prefer the Ninphetamine 2.0.5. kernal over speedmod, and flash that afterwords. I'm considering it as well.
Also, 5.0 doesn't support RTL language. Keep that in mind.
I am confused - whats Ninphetamine 2.0.5. A kernel?
Do i need Lite'ning 5.0 and Ninphetamine 2.0.5 ? And I can update both of them to my phone via Odin ?

You can flash Lite'ning Rom without the Ninp kernel. Lite'ning Rom comes with Speedmod Kernel, which may be fine for you. Like I said, some people prefer to use the Nimp kernel though.
Both can be flashed via Odin.

What to look for in a kernal

Hey guys, I'm not gonna ask the dreaded question "Which Kernal is best?", but I am currently rooted and want to overclock to 1.5, but besides that, what else should I be looking for in a kernal?
What about modems (or is that embedded in the kernal)?
We only have 2 options, Entropy or Siyah and they do not include a modem.
Check the dev section for kernels & modems.

Both kernels we have offer oc abilities.
Personally I would look at stability and battery life but that is just me. Try both and see which suits your needs.
Modems are not associated with kernel and depend on your area. Whichever works the best where you are.
We have two choices here and both are incredibly stable and allow overclocking. You can't go wrong. Basically the biggest difference as far as I can see is the recovery that comes with it which is almost entirely preference.

So if I find a ROM I like but want to experiment with the other available Kernal, is it as simple as flashing my ROM first, then once booted up go into Odin and flash the other kernal i want to experiment with?
Or is the kernal that comes with a ROM the one your stuck with?

Just use CWM to flash the zips provided or Mobile Odin if you prefer it that way.
No need to use a computer to change the Kernel.

Thanks for the quick response chris,
I guess what I'm asking is if I have a rom with the Syiah kernal, is it possible to keep that same ROM but swap kernals, sorry, I just wasn't clear on what your answer meant.
I'm guessing your saying it is indeed possible and just flash the .zip for a different Kernal on top of an already installed ROM.
Sorry, I'm tired...
Changing the Kernel on 2.3.4 & 2.3.6 roms will not break anything.
For CM7, CM9, MIUI etc you have to stick with what is included or see what works with it.

For example, latest Siyah with touch recovery. Awesome for flashaholics.
Your talking of version .14 I assume, if so, doesn't it say in .13 description that .13 would be the last for Gingerbread?
Obviously it works if your using it, so i'm gonna download now...

I need some advice regarding Kernels

Hello
I've come to that point, where I want to save some fuel on my phone. So I thought of flashing a kernel. But I searched on google, with no result.
I am trying to flash a kernel, that is more powerful and more battery saver, than the stock kernel. I planning to flash through odin. I am currently only rooted, with stock recovery and rom.
I would appreciate if anybody could lead me, or link me to a thread that would solve my "problem"
Thanks
There is no such thing as a kernel that's "more powerful and more battery saver". You have your phone setup differently to everyone else, you use your phone differently to everyone else and your phone came out of the factory slightly differently to everyone else's.
A kernel that runs well for me might not run well for you.
I suggest you go the development sections of the forum & read the first few pages and the the last 10-20 pages of the particular threads devoted to different kernels. That way you will get an idea of the features/pluses/minuses of each kernel, and also see other users' experiences with that kernel.
Then you can test different kernels for yourself to find one that works best for you.
Given how simple it is to flash a kernel/try one out & how simple it is to restore a backup & go back to your previous setup if you don't like the kernel you try (or simply flash your old kernel), there's no excuse for you not to try a bunch of kernels yourself.
i start to belive every kernal has an advantge but the stock kernal have all the average requirment ....so stuck with it

You are right, but I have no idea on how to flash an kernel on odin.
EDIT(not really): Aha! I need to flash the TAR file.. If I am right. Also Is there a way to still keep the stock recovery ?
