Hi,
Im looking for a ROM which uses less battery and has good performance. So far i've got VillainROM and WajkIUI. I could'nt find the 2.3.6 version of VillianROM and i think its not out yet. My SGSII is stock 2.3.6.
Also, i read somewhere that there is a 'counter' for custom roms and once the counter goes up, you lose warranty. Is that true?
you will get a best perform rom and batt friendly if you join to it a good kernel and modem but I suggest you checkroom v4 wish is EXCELLENT without too much tweak and removing all the samsung junk so you can still download it again with an app that cam when you flash the rom
and actually I'm on syiah 2.5 gt+KL1 modem and very fine at the moment no battery drain for nothing and everything is smooth as butter
if you read carefully you will not brick your phone and everything is reversible to 100% stock phone actually sue no worry for warranty
there is a counter if you flash an insecure kernel or rom but you can reset with a ''micro jig'' that you can buy on ebay for less than 4$
and with the new clockwork mod app you can bypass the counter by the way and you save the time to connect to the computer and flashing with odin ...

Sorry, Im a noob to all this. What do you think is the best kernel and modem for my rom? I downloaded and flashed XWKK5 and the kernel is
[email protected]#2. Dont know how to find the modem lol sorry
you just have to download any kernel from this site there are few very good !
the kernel you have on it is a stock kernel
you have to follow the direction if you want to root(install cf-root)that match your version, make a backup and download titanium backup (verrrrry good app)
siyah 2.5 gt (the one I use)
speedmod (I used it very good batt life but feel not as stable as siyah) and you are a gunea pig with this one
DK very good based on siyah kernel with a bit better battery life maybe
you have to match your current version wish is kk5
for the modem is the base band in phone info and its should be KI4 at the end if I'm ok or KI3

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 All those custom kernels are based on outdated KF, since that's the latest released kernel source.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.

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.

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.

Hi SGS2 users.
I have been using my stock SGS2 for approx. 1 month now. I have been following with the forums but have yet to do anything with my phone. I have experience with flashing (had an old HTC Diamond 2 using WinMo and did quite a bit of flashing a few years back. I switched to blackberry and has recently returned to xda.
I am completely clueless with the android flashing. I HAVE rooted my phone already though.
So I have seen some tutorials on flashing roms (most are included in the rom description) but what is this kernal flashing. I keep hearing certain kernals performing better then others in terms on bat life and speed.. (such as the nimephatimine(not sure if I have spelt it correctly). How do I use this kernal stuff? Please link me to a tutorial thread if there is one, I tried searching and was unsuccessful.
Any recommendations on ROMs? The top 2 I see are cognition and litening..
Cheers
http://forum.xda-developers.com/showthread.php?t=1075278
theres a nice guide there for the basics of flashing with odin. note this guide is for a complete firmware.
the kernel is just a small part of the ROM and it can be easily changed at any time. you flash it any .tar kernel file in odin as a PDA
It's easy. Download the firmware, extract it, you will get a .tar file, open Odin, add the .tar file into Odin PDA section and Flash it. Simple. A full firmware is around 300 mb.
Same goes for Kernel, you will have a .tar file around 5/6 mb, flash it vid Odin by selecting PDA.
Yes, there are lot of kernels, like you said, Ninphetamine, some others are, SpeedMod, RageMod, Hellcat etc. Each and every one has it's own features. Like Ninphetamine adds BLN feature, Voltage tweaks etc, Overclocking etc. The simplest rooted kernel is Chainfire kernel, it's basically a Stock firmware with BusyBox, SuperUser and CWM and I recommend it. But if you want a more versatile one then I recommend Ninphetamine, which I am currently using.
Read about the Kernels under Dev section for more details.
Regards.

if you are looking for a stable Samsung ROM go for Cognition, LEOMAR or Litening. If you are interested in cooking your own rom you can for the ROM kitchen. romkitchen.org/beta
In case of AOSP or CM ROMs you have CM7, MIUI, Oxygen etc. CM7 is not stable. MIUI looks good but is a battery drain for me.
As far as kernels for Samsung ROMs go Speedmod and ninphetamine are the popular ones.

MIUI is built on top of CM7. Meaning it's equally as "not stable".

Okay, I haven't been able to fully understand this so maybe someone can explain it:
I am using KG2 (Villian Rom). It's a Bell SGS2.
Now, I'm wondering if I can change to KI8 or something else later, or will this phone only work on KG2?
Battery right now, is 8hrs with fairly heavy use. I was expecting 10-12, and I have a feeling its the kernel + ROM. I'm thinking of going back to a rooted stock, but I need to know if I need to use KG2?
Can I change the modem/baseband/etc? I don't quite understand how the versions work.
If I can change it, what SHOULD I be running?
Edit: Take a look at the graph... Maybe with this kind of usage, almost 8hr is all I can really expect. If that's true, then maybe we can just answer the question based solely on the kernel issue. I'd still like to know, to be fair.

1. yes you can flash to KI8 if you like.
2. No, you do not need to use kG2 you can upgrade to any rom you like. Each has pros and cons that you needs to try out for yourself.
3 yes you can change the modem=baseband, firmware or kernal to any combination you like.. versions are based on the original firmware version released.
4. best for battery life so far are the latest releases Like KJ 2 or 3.
if you lower the brightness levels, you can extend the battery a little further.

There are many thread about battery life, such as => http://forum.xda-developers.com/showthread.php?p=16973603
One of the first recommendations is to flash the latest official ROM.
As I want to stay as "stock" as possible, I am running a new stock ROM (XWKJ3) and a custom kernel, which is optimized for a better battery life => SpeedMod K2-18-test8.
Here is the corresponding thread of hardcore, the developer of this kernel => http://forum.xda-developers.com/showthread.php?t=1182498&highlight=Speedmod
So, I recommend to flash the latest official ROM (you can get those as non-wipe versions in Intratech's Official Firmware thread here => http://forum.xda-developers.com/showthread.php?t=1075278).
Then test is as "untouched" stock ROM for performance and battery life.
If you are still not satisfied with it, then flash a custom kernel optimized for ... what you mostly want.
Good luck !

Thanks a lot. To flash the kernel, should I use ODIN or can it be done handset side? Which should I do first, kernel or ROM? Or will some of the ROMs have the kernels in? The thread has a lot of extraneous information and I can't seem to understand EXACTLY what I need to do. I've only ever done ROMS through recovery.
If I install a new kernel, it'll most likely work with the current rom (so for example, flashing a new KJ kernel, and a decent modem (is there one?) ) right? Or do I have it backwards?
I don't mind if I wipe or not, everything is in the cloud... One thing I DO notice however, is that ROMs outside of MIUI don't re-install market apps automatically. But that's something I don't mind doing, anyway.

Too subjective to say - depends on your usage and the kernel.
Custom kernels can be tweaked more than stock kernels - some tweak for performance, some for battery.
Never used hyperdroid, so I can't compare. On my ROM (see sig) I have Redpill kernel. I compared it once against my stock backup, and got about 75 minutes more battery. But it was hardly a scientific test.
Just flash a couple of stock ROMs and find out how battery life is for your setup/usage.
Generally speaking the latest stock is best .
Generally speaking custom roms are better battery life
Generally speaking battery life is a factor of user and the apps and settings on the phone coupled with usage .
Better battery stats and wakelocks are the starting point .

ICS Rom
My current ROM is from westcrip :
http://forum.xda-developers.com/showthread.php?t=1436854
Resurrection Remix ics v9.6 exclusive XXLPH 4.0.3 Full-Wipe
If you're looking for something stable, fast, no FCs(if you install it correctly ), no orange triangle when you boot your phone(this is not the most relevant because there is an app to remove it, but it was a nice surprise the first time I booted the phone), I would recommend this one.
Hope this helps.
Hey guys,
I'm here because I'm new to flashing, rooting and whatever comes within this territory. I own a Samsung Galaxy S2 which was bought from a retail store in New Zealand. It's not an imported phone however Vodafone is its "Carrier" of choice.
What I want to do, is flash the device with this ROM because I am having battery drain issues with the Stock ICS 4.0.3 firmware. I have tried everything, removing apps, wiped cache partition a few times, but when Wifi is on 24/7 it drains from 100% to 0% in literally 8-9 hours flat. That's with me doing absolutely nothing with the phone.
I installed BetterBatteryStats and Battery Monitor Widget. The latter app shows my phone discharging -8.0% while Wifi is on and -0.2% when it's off. BetterBatteryStats doesn't indicate anything that is obvious.
So, I'm hoping a ROM like Lighnting may help. Plus, I love it's theme, look and feel.
Down to my real questions.
If I have any issues during flashing of the ROM, can I return the phone back to its stock firmware?
What is the procedure to do so?
Can anything go wrong?
Thank you
STEALA
