same here,

my s2 is very hot and was found battery drain,

i am using warmlite 12.0 and back to dark kinght 1.9.2 kernel
[Galaxy S II Original Android Development] aziz981:
Been Using k-25, and now changed to k-26.

Didnt noticed any visible improvement,it is exactly the same as before.

One thing keeps bugging me though, in both versions, sometimes my apps fail to open. They just dont respond even i click them multiple times. I have to restart the phone to get working again. Tried wiping cache and dalvik cache, used kernwl cleaning script, fixed permission. Nothing helping. It occurs once ot twice daily. Anyone else having such problem??
[Galaxy S II Original Android Development] Veeko:
does this kernel work with rootbox rom? i was previously using speedmod with checkrom on gb. thx.
[Galaxy S II Original Android Development] Gorjess:
No, speedmod are based on sammy's kernel..

[Galaxy S II Original Android Development] kotaxor:
Maybe it's just my phone... But version 20 seem to generate so much less heat n battery life is better.

So far, on my phone, running stock rom, lp7, the best battery life is still version 19.
[Galaxy S II Original Android Development] youness1052:
Try K 25 !!!
[Galaxy S II Original Android Development] pedestre:
Thank you very much, k3-26 is working fine and I had no boot hangs after 10 reboots and 3 cache and Dalvik wipes while I was testing my little modifications. No hot issue at all and smooth and fast as always. I'll have to wait 3 cycles to check battery but I'm sure that it will be great again.

One cuestion: why did you change compiler to an older toolchain? I didn't notice any stability issue with 20120326 toolchain? Is there something that I didn't realize?

Thank you and congratulations for your contribution to this community
[Galaxy S II Original Android Development] tomurbanowicz:
What are differences between K3-26 and stock kernet ex. LPW?
[Galaxy S II Original Android Development] It_ler:
Stock kernel is 100% from Samsung and official release.

SpeedMod is a custom kernel, optimized for speed and battery life (mainly by removing debug parts).

For further information please have a cloder look at the OP and Hardcore's changelogs.
[Galaxy S II Original Android Development] Hayth:
Recently flashed k26 and have been extremely pleased with it, already beat my max on screen time :)
[Galaxy S II Original Android Development] Beso:
This kernel rox! :)

Is K3-26 ready for Android 4.0.4?
[Galaxy S II Original Android Development] youness1052:
which firmware are you using ??

i tested K 26 with wanamlite V12.2 and its draining my battery, so i flashed back K25 !!!

Nb: i used Kernel cleaning script
[Galaxy S II Original Android Development] hardcore:
Just uploaded a K3-27T version with slightly different options to see if can really get rid of the occasional boot hang.
[Galaxy S II Original Android Development] afiqsabri:
is it working for 4.0.4?, afaik the camera and video wont show live preview once this kernel install, at the time being
[Galaxy S II Original Android Development] Lancez:
for 4.0.3 only, 4.0.4 source code has not released yet
[Galaxy S II Original Android Development] Karpfenhai:
Hello hardcore, thx again for your brilliant work, smooth as silk as usual!

But :)

It seems since k25 Init.d scripts are not longer working (device freeze)

Did you change a kernel switch?

Here is my usual script:

#!/system/bin/sh

sleep 20
echo "Start working"
echo "Set MIN Scaling Frequency"
echo "200000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo ""
echo "Set MAX Scaling Frequency"
echo "800000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo ""
echo "Set Min Scaling Suspend Frequency"
echo "200000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_suspend_freq
echo ""
echo "Set Max Scaling Suspend Frequency"
echo "200000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_suspend_freq
echo ""

Thx for your response.

[Galaxy S II Original Android Development] pedestre:
I think new mach-exynos cpufreq (in new sources) has problems when you change any policy. It was something that also happended in older sources but it was fixed in speedmod K3-12 (if I'm not wrong).

Perhaps Hardcore could tell you more about it
[Galaxy S II Original Android Development] Karpfenhai:
Yes your right, the initial ICS releases have suffered with this, i think Gokhan (Siyah) was the first dev able to fix this, im pretty sure HC will find a way soon too. Thx for the heads up ;)

Hello everybody, has someone tried it on XWLPO? Can I use Odin to flash speedmod? Thank you.
[Galaxy S II Original Android Development] DanDroidian:
Boot hangs with older versions, but NONE with 27t after a day and a half! I think it's ready to go!
[Galaxy S II Original Android Development] zool84:
this kernel isn't "boot hang" free

i don't care about this " issue " i don't reboot so often :p
[Galaxy S II Original Android Development] It_ler:
I have not yet used SpeedMod K3-27T on XWLPO, but you can flash the tar file of the kernel with Odin ... yes.
[Galaxy S II Original Android Development] DanDroidian:
Works for me, just saying!
[Galaxy S II Original Android Development] :
You can use ODIN or Mobile ODIN to flash speedmod kernel.

As LPO is a 4.0.4 ROM, it still might give issues with Bluetooth and Camera. Haven't tried K3-27T yet, but on K3-26 the incompatibility still was there (I think it's because the 4.0.4 Kernel sources are not out and therefore the Speedmod is still based on the 4.0.3 Kernel from Sammy)

If there are news, so if K3-27T already solved BT&Camera issue..let us know.

I think there are more than myself wating for a Speedmod compatible with 4.0.4 Roms....
[Galaxy S II Original Android Development] lsv-1:
Thank you It_ler and GeScha, I'll wait for a fully working version of speedmod 4.0.4 before attempting to flash it. GeScha, how did you root XWLPO? Someone mentioned that CF-root XXLQ5 does the trick, however I don't want to flash something that increases the binary count.
[Galaxy S II Original Android Development] It_ler:
If you are rooted, you can use Mobile Odin app to flash new stock ROM with CF-Root kernel at once.

That's how I did it.

EDIT:

You can still use TriangleAway app to remove yellow triangle and reset flash counter after flashing with Odin.
[Galaxy S II Original Android Development] :
Mobile Odin with EVERROOT enabled ;)

I'm still on Stock Kernel.
[Galaxy S II Original Android Development] hakaz:
FINALLY we have a 4.0.4 ROM Source at Sammy's OSRC (GT-I9100_ICS_Opensource_Update7.zip) .

I hope hardcore will hack into it for a 4.0.4 speedmod version ... Please :)
[Galaxy S II Original Android Development] Agent_Adodas:
So, is this the long awaited sources which will give us custom ICS 4.0.4 kernels?
[Galaxy S II Original Android Development] :
Yeah, that's good news. i hope Mr. Hardcore finds some time to create a new Kernel. Will boost 4.0.4 Sammy ROM :)
[Galaxy S II Original Android Development] zool84:
yeah, hope that it will be solid like k3-27T
[Galaxy S II Original Android Development] monster75:
No issues with K3-27T?
[Galaxy S II Original Android Development] ata1918:
let me guess..the new sources have mmc_erase enabled?
[Galaxy S II Original Android Development] pedestre:
I'm afraid so,

In Update7, in "/drivers/mmc/host/mshci.c" and "sdhci.c" there is this code line

mmc->caps |= MMC_CAP_SDIO_IRQ | MMC_CAP_ERASE;

^o^ ^o^
[Galaxy S II Original Android Development] hardcore:
K3-28:

- Rebuilt on new GT-I9100_ICS_Opensource_Update7 source code

- Should be compatible with 4.0.4 ROMs

And yes, MMC_CAP_ERASE is disabled for safety.
[Galaxy S II Original Android Development] hakaz:
I looked into the source and yes, it is enabled in the original source files. :p

And thanks alot hardcore for the safe compilation :good: :laugh:

Did you wipe cache and Dalvik before flashing k3-28?

Just to be sure

What about bluetooth?
[Galaxy S II Original Android Development] Jaromos:
K28 works fine with 4.0.3

BTW: I get a notification "klogctl: function not implemented". Looking for that in the internet, I figured it could be a kernel related issue. Is it? has anyone experienced that? (while trying to read Droidwall logfile)
[Galaxy S II Original Android Development] Fittip4ldi:
Same problem.

The Bluetooth is OK but the Camera doesn´t work.

I apply this patch to solve the problem with the camera: http://xdaforums.com/showthread.php?t=1772931

Kernel seems super quick, very slick, Quadrant bench up 120 points compared to k26 on my SGS2. :)

However, cpu seems to stay on 1200 a lot. :mad:
[Galaxy S II Original Android Development] hakaz:
Tungstwenty's tweak works great for me too, the two files he uses are the 4.0.3 versions (I compared them to XWLPI and they are identical). But for me the question rises if they are really compatible with 4.0.4 fearing something else could break (especially using hwcomposer.exynos4.so from 4.0.3). And yes, I did my wipes before installing K3-28 ;).

I will revert to the 4.0,4s and stay with the black screen until hardcore shows up with a modified kernel version.

Hello Hardcore and everybody working on Samsung kernels for 4.0.4,

I don't know if this helps somehow but the camera in 4.0.4 (LPO tested) seems to work fine if the Update7 sources are compiled with a stock LPO initramfs and Codesourcery 2010q1 - I'm running a test kernel build here without any other changes besides removing MMC_CAP_ERASE from drivers/mmc/host/mshci.c - camera seems to work fine.

Maybe you can get some useful information from this, maybe you already know it, maybe someone else tried and reported this, too (don't know) - I just wanted to try to help somehow.
[Galaxy S II Original Android Development] DADER:
Hello xda members and devs

First of all thanks hardcore for your work

& i want to ask a question, this k3 series supposed to work with 4.0.3 not 4.0.4, right?
[Galaxy S II Original Android Development] robsonhcosta:
Hi Hardcore,

First I would like to congratulate the great job he has done with the kernel.

I installed today the K3-28 and my compass and auto rotate stopped working.

I am using in my galaxy s2 the rom of Chile 4.0.3 / XXLPS modem.
[Galaxy S II Original Android Development] Naytmer-fr:
+1 here, the same.

Using Criskeloservan v12 rom 4.0.3 LPW
[Galaxy S II Original Android Development] zool84:
yes the k3 series are for ICS, the last one k28 is from the last samsung sources and it's supposed to work fine on 4.0.4
[Galaxy S II Original Android Development] hardcore:
Seems like K3-28/29 auto-rotate doesnt work, at leats on 4.0.3 roms.

Does it work on 4.0.4 roms?
[Galaxy S II Original Android Development] tonysac:
I confirm that auto-rotate doesn't work on 4.0.4(resurrection 2.6.1) also:(

Keep walking Greece
[Galaxy S II Original Android Development] drelite08:
Right.....

Firstly I can say that on K29, LQ7 which is obviously a 4.0.4 firmware, auto rotate is working fine for me.

Secondly for those who are having black camera screen with this, or in fact any other custom kernel for 4.0.4, use this fix in this post and you will get it back. http://xdaforums.com/showthread.php?t=1772931

Use the fix in the link I posted.
[Galaxy S II Original Android Development] ExRapier:
Is the kernel safe to use with 4.0.4 roms? Does it have the MMC erase bug aswell or did hardcore remove it while compiling the kernel?
[Galaxy S II Original Android Development] mrcreativity:
How is this even working on a non Samsung ROM?
[Galaxy S II Original Android Development] pedestre:
Of course, Hardcore has disabled MMC_CAP_ERASE in the kernel. It should be safe, in fact nobody has reported any brick problem.

I can confirm that in 4.0.3 auto-rotation doesn't work
[Galaxy S II Original Android Development] Lukiqq:
Thank you Mialwe, from what I see the main change is CONFIG_VIDEO_SAMSUNG_MEMSIZE_FIMD=12000 which has been increased from 9000. I'm using my new kernel (not yet published) compiled from Galaxy Note Update4 and after this change video playback and camera preview is working fine!
[Galaxy S II Original Android Development] hardcore:
I'll give it a shot later on.
[Galaxy S II Original Android Development] Brotuck:
On XXLQ7 the autorotate also works fine. Only thing is the camera preview that is black.

The fix (with files from 4.0.3) works fine.

- Minor compiler flag changes

- Camera driver fixed for 4.0.4 ROMs

Note that this version will break auto-rotate and the compass on 4.0.3 ROMs. But it works with 4.0.4 ROMs.
[Galaxy S II Original Android Development] VAXXi:
On XWLPF (4.0.3) with K28, rotation doesn't work (read values of sensors are null), but the sensors are actually monitored - the graph lines show the phone being shaked. Weird.

If you use a 4.0.4 ROM, go ahead with K3-30.

If you use a 4.0.3 ROM, better to stick with K3-26, unless you don't care about the auto-rotate or compass.

Hi hardcore, first I would thank you for this n1 kernel I use it since K2 on my Galaxy S2. I had a question can you replace it with supersu.apk from Chainfire because you use the old superuser.apk in your kernel and it was never updated since 2011. Supersu is more up to date and got more options. So what do you thik?
