Here you are mate http://db.tt/jnPQxOhM

Hurry up, cause i'll be deleting it in the next few hours.
[Galaxy S II Original Android Development] Mr.Greg:
Guys, this kernel is compatible with ICS rom?
[Galaxy S II Original Android Development] MistahBungle:
Without Colonel Sauce, not likely.
[Galaxy S II Original Android Development] It_ler:
Thanks hardcore for that fantastic kernel.

SpeedMod K2-21 is very, very stable and fast on my phone.

As I like UV (has better battery life on my phone), I just test latest Phenomenal (4.0) kernel, which is based on your SpeedMod K2-21 but with some undervoltings.

For those you are interested ... here are my latest test results => http://xdaforums.com/showpost.php?p=22203676&postcount=903
[Galaxy S II Original Android Development] jonny68:
I may go with this latest update as i went back to K2-19 test 5 as K2-20 wasn't good with regard to battery life but by all accounts thus latest update appears to be better
[Galaxy S II Original Android Development] chrisjcks:
Why not just undervolt on speedmod?
[Galaxy S II Original Android Development] kokoboko73:
What rom do you have flashed. i tried almost all kernels on few roms and still my battery is draining fast. i tried undervolting cpu and gpu with tegrak ultimate and didnot make big difference. i am really lost i dont know what i am doing wrong. any advice is most welcome. Now i am with checkrom revo4 and latest speedmod kernel and see what will happen.
[Galaxy S II Original Android Development] androidkid311:
Also try freezing things it saves battery as well :)

looks like an iphone but powered by android baby!!!!
[Galaxy S II Original Android Development] Soviet_Rebel:
Hi mate, as u can see from my sign I'm on checkrom revolution hd v4 and speedmod kernel k2-21. No undervolting and no freezing apps.
[Galaxy S II Original Android Development] lokhor:
Anyone else having issues with auto brightness outdoors? Mine is not going bright enough to see. Using K2-21
[Galaxy S II Original Android Development] hardcore:
Nothing specifically to do with the kernel. Turn off display power savings in the settings, it limits brightness somewhat.
[Galaxy S II Original Android Development] It_ler:
Thanks for the suggestion.

Since hardcore enabled Tegrak OC support, this is a valid option.

But I am lazy and do not want to adjust every configurable setting to reach the "limits".

So, I prefer using the developer's default (or most popular) settings.

And reading fenomeno83's post here => http://xdaforums.com/showpost.php?p=22173471&postcount=891, there are still some settings you can not change by configuring SpeedMod.
[Galaxy S II Original Android Development] Mujodroid:
Hello every one i cant flash kernel any more ...... i tried to flash k20-21 i had an error iam now on k2-18 ??
[Galaxy S II Original Android Development] betoNL:
Just install Tegrak Overclock Ultimate app and undervolt as much as you want..

Just dont blame the kernel in case you get stability issues...

Thanks...

I did search before (here and at theGNotes speedmod thread and asked over there)...but didn't search good enough ...and got no answers over there :rolleyes:

Try using this before flashing the new kernel.

http://xdaforums.com/showthread.php?t=1363738

Go inside cwm recovery and flash the cleaning script before flashing the new kernel.

It would be awesome to see an ICS version of this kernel later, even more awesome if it will support AOSP to use it with Cyanogenmod 9. :)

[Galaxy S II Original Android Development] al_madd:
try flash back to stock ROM..use for a few days...

flash speedmod kernel...
[Galaxy S II Original Android Development] kokoboko73:
Thanks I will do that and see what will happen. I started wondering if there is something wrong with my battery. I might have to replace it. I did calibration and no change again.
[Galaxy S II Original Android Development] Soviet_Rebel:
WTF:confused:

Then i would try something like this:

-Recovery mode

-Clean cache and Dalvik cache

-Flash Checkrom V.4 once again over your previous installation (you won't loose nothing, it's not a full wipe rom)

-Do not reboot

-Run kernel cleaning script

-Flash latest speedmod kernel

-reboot
[Galaxy S II Original Android Development] SaneinOne:
Flash CF-Root and then Speedmod.
[Galaxy S II Original Android Development] RyanParty:
Just like to add, those of you who have the "Installation Aborted" message, I had it too.

It was because I downloaded the developer rather than the CWM version of the kernel. Please make sure you've downloaded the CWM version ;D

Great kernel SpeedMod SGS2 K2-21
[Galaxy S II Original Android Development] shumo:
i have a question please

why is the color of the phone signal different in some parts of the line ? in the picture i attached

i just noticed this .should this be a problem of some sort ?
[Galaxy S II Original Android Development] nikzDHD:
That's your signal strength, the pale yellow is when you had poor signal, yellow is sort of the normal signal range and when it's green that's when you are in a really good signal area.

You can try changing your modem to see if strenght improves.

As you can see from my screenshot on that particular day i had really good signal then a few areas with poor signal and the red when i had no signal.
[Galaxy S II Original Android Development] slig:
On k21 my battery life is INSANE: 3 days and still 52% left

1h 30m - calls, 30m screen on

Thanks Hardcore !
[Galaxy S II Original Android Development] alexkno:
Would be awesome to see speedmod for ics. Lpb rom is really stable for me and now for 5 days in daily use. I didn't have any soft reboot or similar. So from my point of view it's time to look into it to be ready when official release is there.

Thanks hardcore for your awesome work which made my phone on gb to what i need!

[Galaxy S II Original Android Development] slig:
Yes because lately I use my gs2 mostly as a phone not a toy. No time for that in a last few days.

Still ver 21 has lowest battery usage from Android OS in my case. It's first kernel on which Android OS isn't on top of the battery usage list. Great kernel.
[Galaxy S II Original Android Development] billab0n6:
What modem are u using?
[Galaxy S II Original Android Development] gorillaCF:
i'm wondering if anyone encountered this:

pressed the power or home button, it'll show the home screen first before showing the lock screen. seems like a slight lag/delay.

is there any solution to this?
[Galaxy S II Original Android Development] MistahBungle:
Never mind. ID-10-T error on my part ;-D
[Galaxy S II Original Android Development] kotaxor:
Facing the same problem here....even with N.E.A.K...the same thing.

Only with stock kernel..this does not happen??:confused:

Also when plug in charging...this does not happen.

Anyone know how to resolved this?...would be grateful.
[Galaxy S II Original Android Development] gorillaCF:
i dont encounter this problem when i'm using siyah's latest kernels.

not sure if this is kernel or rom related :/
[Galaxy S II Original Android Development] kotaxor:
Stock ROM, stock kernel...no problem.

Stock ROM, speedmod or NEAK....this problem.:confused:
[Galaxy S II Original Android Development] monster75:
The same problem and besides I've noticed that after unlocking, if I keep pressing home key, it doesn't open task manager. Otherwise if I try after moving the desktop windows, then it works. Is it normal?
[Galaxy S II Original Android Development] shumo:
i have the same problem sometimes. even with stock unrooted 2.3.3 , .5 and .6

it used to drive me crazy now i just don't care about it :) . i think it's has something to do with the phone waking up from deep sleep ...
[Galaxy S II Original Android Development] kotaxor:
Not likely...

The first time I press the power or menu button, there is this flash of home screen. If without doing anything, I let it sleep again, the next time I pressed, there would be no flash of home screen.

Believe me, I tested it numerous time n everytime it's the same.

This show its not due to phone waking up.
[Galaxy S II Original Android Development] monster75:
OK I understood. It seems to be a MagicLocker bug. Using the defaul locker, the home key works fine:o

---------- Post added at 11:18 AM ---------- Previous post was at 11:17 AM ----------

It's the same also with the stock 3-ITA ROM (2.3.5).
[Galaxy S II Original Android Development] shumo:
exactly.

the exact same thing happens to me

exactly like you described it above. it might be related to the "quality" of the lockscreen picture .

if you find a solution to this let me know cos i would be interested . but as i said when i first noticed it i did a lot of testing and tried to find solutions or at least explinations of why this is happening . but i did not find anything

one thing i know is that it has nothing to do with the rom or kernel cos i have this on stock roms and kernels before rooting and now on any custom rom ... with different kernels ( speedmod, siryah, etc )

[Galaxy S II Original Android Development] mathsmart:
no problem here you should try hyperdroid v6 based on XILA2 verrry smooth and you still can flash your KI4 modem if you like but the las LPB is rock stable here after few cycles of charge

and no flickering of the screen with penom 4 extreme(based on k2-21 but with UV) on my phone !

and I'm running the last vert 1.9 theme created for hyperdroid wish is full of win !! I also restored one of my winner KK5 stable rom at that time siyah 2.2i-p and I really can feel the smoothness the new LA2-LA3 firmware give up and also the evolution of the kernel just like speedmod here ! very smooth and don't want to look back now thanks a lot mate for this wonderful kernel stable and simple as it should be !

is it true the last k2-21 is based on the la2 kernel ?

I've encountered a strange problem a few times: The screen just doesn't turn on when pressing the power button. I have to remove the battery for the phone to work again. What could cause this?
[Galaxy S II Original Android Development] slig:
Yeah I'll probably try new roms. "Problem" is that my XXKI4 + speedmod is so great that I have no strong motivation. Basically everything works perfect for now including battery, signal strength, smoothness, stability, gps etc. - not even a single issue for me. Maybe just don't know that my gs2 can be even better :)
[Galaxy S II Original Android Development] panoskw:
Imagine using The GingerMOD plus SpeedMod [K2-21] ! It's perfect...

im still on 18 cuz i feel its the perfect balance of smoothness and power saving

[Galaxy S II Original Android Development] panoskw:
Thank you for sharing man, i'll have to try 18 and 21 is an exceptional kernel..thank you so much hardcore !
[Galaxy S II Original Android Development] jonny68:
I cant keep up with all these updates i hope it;s not gonna be like Siyah kernel 4/5 updates every day,madness it was:eek: im quite happy with K2-20 so so unless this latest update is really much better ill stay with that.
[Galaxy S II Original Android Development] kotaxor:
To me...k21 is much better than k20.
[Galaxy S II Original Android Development] JmPTaz09:

So have u reconsidered supporting the i777 model :-)

Gokhanmoral has been doing it for months and Never have I seen it introduce any problems not in the mainline kernel. I'm not sayin, I'm just sayin. :-P
[Galaxy S II Original Android Development] d8389:
Hi,

Can you add support for CWM Manager 3, fix incorrect SD Cards names and add hard buttons support in future releases ?

[Galaxy S II Original Android Development] y17dt:
To show you even more freaking images of hardcores Kernel.

My Mum has got a S2 and she only uses it, when she is on Holiday or needs Internet somewhere else but at home. She usually switches off the S2 when she doesn´t need it. But not in the last few days.

Look at the results, with CheckRom v4 on K2-18 Test 12 (I know, its outdated), DataDisenabled...
[Galaxy S II Original Android Development] break1:
Nice, but probably 99% of the time is standby. So u cant really compare it with daily usage.
[Galaxy S II Original Android Development] al_madd:
I dont know wheter this problem related to my firmware or kernel..

Im using stock 2.3.6 DXKL1 with K2-21

my problem is when using livewallpaper..

when I set my wallpaper with live wallpaper..

after I plug USB cable it will turn back to stock wallpaper..

anyone with this problem??
[Galaxy S II Original Android Development] pikachu01:
Your live wallpaper is in the SDcard? It's normal. Unplugging it will go back to live wallpaper :)
[Galaxy S II Original Android Development] v1rtu4l:
it is not even a good result, since they are many times the phone wakes up, even though the screen is off. with proper kernel and proper apps that don't wake up the phone without anyone using the phone actually you would even get better values for battery life !
[Galaxy S II Original Android Development] Soviet_Rebel:
Wow a real hardcore user. :)

My gs2 without data and with screen off, looses 1% every 10 hour (more or less). But what's the point in this? Not using the phone? And you have HUGE wakelocks mate, download betterbatterystats to find out where's the problem.
[Galaxy S II Original Android Development] BrandoHD:
You guys have totally misunderstood the post of the user, it's not a competition, and it's not meant to be personal, it's a user posting 6 days on battery with extremely light usage

Today my screen didn't turn off for about 2 hours. In any case my SGS2 lost 30% battery, it got warm and I hope the screen didn't burn in.

I really liked this kernel, but as it isn't the first time I will have to change :(

Speedmod k2-19 test5
[Galaxy S II Original Android Development] Soviet_Rebel:
Did you even bother reading my post? Perhaps you have misunderstood it. Where's the competition?:confused:

I consider "light usage" a totally useless scenario for measuring the battery performances of a kernel, so i pointed this out. Also, our friend, has some serious wakelocks problem and i felt the urge to suggest him to investigate.

Where's the problem?

Have a nice day.
[Galaxy S II Original Android Development] huuub:
Try phenomanal 4.0. It is speedmod with undervolting and all settings already set. Really good.

[Galaxy S II Original Android Development] ov3r85:
hello

i am using stock 2.3.6 kk5 with latest speed mod k21

everything works perfectly but i have a question

after flashing speedmod after cf-root the CWM manager stayed version 3.0 and sais i dont have all the features available.

how do i update CWM?

thx
[Galaxy S II Original Android Development] shumo:
if you are reffering to cwm manager the app , then it is not fully compatible with speedmod . but although it shows an error saying that it is not compatible you can use most of ( if not all ) the features in it

if you boot in cwm you will see that you have version 5 point something

it should be ok
[Galaxy S II Original Android Development] ov3r85:
thx for reply :)
[Galaxy S II Original Android Development] y17dt:
I just wanted to show you a nice screenshot! Nothing else!

As I told you this is my mothers S2. I only sometimes get my hands on it. BetterBatteryStats is installed and I found the problem. So everything is fine now. But thanks for the info.
[Galaxy S II Original Android Development] komsa:

How do i downgrade it? Thx
[Galaxy S II Original Android Development] JacquesR:
The APK for version 2 is somewhere on these boards - sorry, but I don't have the link. Search for that, download it, and then with something like Root Explorer, replace your current CWM in system/app with the downloaded one.
[Galaxy S II Original Android Development] komsa:
uninstall 3.0 and install 2.0 :)

K2-21 is very good indeed on a par with K2-19 test 5
[Galaxy S II Original Android Development] monster75:
Now I'm trying this voltage profile:
[Galaxy S II Original Android Development] It_ler:
Sorry hardcore for asking again, but I can't find an answer to it:

Do you think about adding the support for Xan's voltage control app (VC) into your SpeedMod kernel?

Simone201 with N.E.A.K. and Gokhanmoral with Siyah kernel are compatible with VC to change voltages, frequencies, etc.

That is the only thing I am missing in SpeedMod.

P.S.:

I know that you just integrated support for Tegrak OC app, but for VC, there is a free lite version, which I always prefer. (Tegrak OC is only available as paid version.)

I appreciate any answer ... even if it is negative. It is "your" kernel and that's maybe what makes it so good !
[Galaxy S II Original Android Development] carlos67:
K2-21 the best so far for me.

I agree totally. I've recently upped to k2-21 from 19 test 5.

Not much in them but if anything, latest one just edges it. Just. Heres my stats. Pretty impressive I think - 2 days and 2 hours with 7% remaining after 3 hours display on time and a lot of voice calls. Stock battery and CRR v4 :)

btw. display set manually to 50% brightness so potentially even better battery at, say, 20% but I find it a little too dark at 20%. 50% a good balance me thinks. Also, stock speeds and voltages and xxkI4 modem. Fast dormancy enabled.
[Galaxy S II Original Android Development] panoskw:
Hi, could you share with us what rom you're using custom/stock, if you're on custom, its name ? thank you
[Galaxy S II Original Android Development] carlos67:
Already have done - CRR v4 (see above). CheckRom Revolution hence CRR.
[Galaxy S II Original Android Development] panoskw:
ahhhh, thank you my friend didnt catch the shortcut, a wise choise for custom rom :)

Hi Hardcore,

Thank you foe such A great Kernel in terms of lightness, speed and battery saving.

I have a problem though, I am on Stock JPKJ2 with K21. I have been always using Stock ROM with Siyah 2.6.x first then NEAK 1.3.3. I ran GS2Blitzer1.5 from CWM for cleaning and then installed Speedmod K21. Phone is perfect while using but when the screen is off and left for sometime unused it just does not turn on and i have to restart it using Power and home and when it turns on i find out that i lost about 30% battery.

Last night i locked it with 93% battery and next morning found battery dead and could hardly manage to charge it as it was giving a Yellow triangle while charging and phone off.

I managed to enter CWM and deleted Battery Stat and it started to recharge.

I have Set CPU profiles for screen off to lower CPU to 500 and i noticed that the phone also doesnt set max cpu to 800 while using as set. Max cpu keeps at 1000.

What is the problem please advise a i really like ur Kernel as i am seeking best battery saving.

Regards
[Galaxy S II Original Android Development] al_madd:

dont use profile..just keep default just like hardcore compile this.kernel..
[Galaxy S II Original Android Development] It_ler:
Thanks for your answer.

I can assume some reasons for that ... (and I have to assume, as you did not gave the reason explicitly)

Anyway: Your kernel is absolutely stable, very smooth and has got excellent battery savings on my phone.

Will post my results as soon as all my tests are finished.
[Galaxy S II Original Android Development] tghandour:
Thanks Al_maad I tried that and disabled all Set CPU/CPU master settings for CPU frequencies and profiles, charging and will try it today.

Any idea where can I find Void Kernel Thread/Post or where can I download it from as I been searching through XDA for a couple of days but in vain.

Thanks again

K2-21 Battery drain

Thanks nikz for clearing things out for me. since i installed Speedmod K2-21 I had this battery strange problem which i posted here. I disabled all profiles and settings (SetCPU, CPU master, System Tuner,.....) and i am testing it now.

However after last night battery drain, the phone took today almost 4 hours for a full recharge and when i unplugged the charger after 100%, battery reading dropped to 98% in few seconds and then to 97%.

I replugged the charger again till it reached 100% and did a battery clibration (wipe the battery stat file) and rebooted to see what will happen.

I had previously Siyah and NEAK and cleaned before flashing Speedmod.

Am I doing something wrong here that is affecting battery specially in Screen off mode?
