after flashed to the speed mod kernel, the phone cannot wake up, have to pull battery. After reboot its still the same, and battery drain rapidly within few mins as well. :(

it did happened on speed mod kernel t40 + Criskelo Rom v20 as well, im not sure what is going on, my baseband version is XXKI3 ..
[Galaxy S II Original Android Development] iamkalabaw:
I tried asking this days ago but for whatever reason, my post was deleted, so let me ask it again. @hardcore, would it be possible to release the following screen tweaks...

- MDNIE screen sharpness tuning (improves text readability)

- MDNIE color tuning (reduces over-saturation of color)

- Lower brightness at low-light levels

...as a flashable zip. I'm a big fan of your kernel and would like to take it with me all the time. However, it does not work with certain ROMS that I would love to try (CM7, MIUI). I share your sentiments that the default sharpness and saturation is a tad off, hence, my question. So is it possible?

It's normal. The best way is using a usb jig.
[Galaxy S II Original Android Development] AndreiLux:
Reflashing a stock kernel (CF), and then flashing a custom kernel from inside the phone is easier. Triangle also disappears.

[Galaxy S II Original Android Development] Molitro:
The AOS deosn't hit you too much. Couple of questions, if I may.

Where you on 3G/H the whole time? And did you use wifi at all? (I usually am on wifi, and is when the AOS bug hits me the most, that's why I'm not using speedmod but Siyah. I always was a speedmod fan on froyo on the SGS)

On the AOS bug, is there a reason to not use that .14 version of the kernel instead of the .7, that, at least parcially gets rid of the bug?

I would definitely use speemod if I could shake off that damn bug that kills my idle battery life.

K2 is really faster than t41 for me... Boot up is almost instantaneous!!! Amazing speed and smoothness, no lags or whatsoever, though I can't go past 3800 3900 in quadrant for those who believe in this kind of tests.. Fyi Cf root went all the way to 4000 4050, t41 was a bit lower than k2-1.

Can't wait to see battery life ;)

[Galaxy S II Original Android Development] Radikaal:
Did you wipe cache & dalvik prior to flashing?

Testing this one now, gonna compare it to other kernels in 4 different benchmarks after rebooting phone twice.

Performance in launchers and menus will be tested tonight together with battery life after benchmarks! Used to be my favourite kernel the t39 on KH3 roms, but since KI3 i always felt there were better choices. But hope this will change again.

---------- Post added at 01:51 AM ---------- Previous post was at 01:19 AM ----------

Okays benchmark scores after flash, startup and a reboot:

First runs in antutu & CF Bench, 3rd run in Quadrant.

5722 @ Antutu, usually get around that first run. Got 5650 with previous fastest kernel after a fresh reboot @ first run. Had a decent amount of better CPU & Ram scores thought compared to SGS II in scorechart, althought fell behind on total score because of database & sd card read which usually needs one or two tries to get higher.

6350 @ CF-Bench, previous 6299

Linpack: 91 MFLOPS as best result in 20runs on multithread. Got 93 on other kernel, only benchmark it was slightly slower in which could be coincidence ofcourse.

And 4022 @ Quadrant. Second time ever ive gotten over 4k at stoch MHz. I usually tend to stay between 3700-3900.

And from about 5minutes of testing scrolling in homescreens feels smoother then ever, think this is the kernel im going to stay with unless it will have some battery drain bug :D GJ hardcore! :)

Kernel im comparing with is the kernel in the hyperdroid rom which been the fastest for me until this.

-Edit- Also got 4230 in Smartbench 2011 s, in their score shart the galaxy s2 at 1200Mhz normally gets 3700-3800 :D

[Galaxy S II Original Android Development] drelite08:
Started getting random reboots straight away. Back to 41 for me too.
[Galaxy S II Original Android Development] Jonjungle:
you have to give the kernel 3 days to settle in, make sure to wipe battery stats etc. I had the same issues with T41 with the battery not lasting a single day but now after 3 or so cycles [charge full / discharge full] it's fantastic and manage 2+ days!

I'm sure that K2-1 will be a further improvement over T41 and can't wait to try it out myself.
[Galaxy S II Original Android Development] :
I agree, T39 has been the most stable and longest battery life for me.

Btw nice, you are in Iran. I am half Irani but I live in the United States, and my Persian sucks. All I know are the swear words.
[Galaxy S II Original Android Development] :
i installed the new kernel last night...after about twenty minutes the battery went down like 5%..really was not happy..so switched over to a different kernel.....anyway cutting story short i thought i try again....charged it overnight....woke up like early this morning and stayed and browsed for a good 2 hours on the phone in bed...battery life after 3 hours counts as 2hours screen on time and 75%battery life after 4 hours....so pretty impressive....many thanks to hardcore..thanks

LeoMar 2.7.1 atm with the K2-1 Speedmod. Best benchmark scores and real speed ive been getting then on any ROM/kernel so far!

---------- Post added at 04:51 PM ---------- Previous post was at 04:32 PM ----------

@formidabilus: Yes, that works fine.

Althought i recommend you wipe dalvik cache & cache in recovery if you have access to that before, but its not needed.
[Galaxy S II Original Android Development] formidabilus:
How can I do that? Go intro recovery and there is an option there to wipe dalvik cache and cache? and what this wipe involves, app and data? Should I make a back-up from CWM? Thanks!
[Galaxy S II Original Android Development] fidorulz:
Goto recovery and select the wipe cache option and then confirm. Once done in recovery select advanced then wipe dalvik.

No backup needed as this only wipes cache info no personal, app or phone data

Set a profile for set CPU for min of 200 and max of 500 when screen is off and set priority to 50% and select conservative

For wake select on demand and 200min and 800max

Reboot and after reboot let phone shut screen off and leave it for about 5min

Wake the phone and check if CPU is stuck at 500 for about 5min

OMG, first of all would love to thank the Dev for the best kernel Ive used on on SGS2, super smooth, battery life is good and thank you for making a solid and lean kernel...I love it but is there any possibility having a version without the colour tunning? personally love the over saturation lol
[Galaxy S II Original Android Development] Tyrol:
Seconding this! Thanks for the super snappy kernel, love it so far! I personally like the over-saturation too, so with colour tuning I had to set Display Mode to Dynamic to achieve the same effect. If colour tuning were optional, that'd be awesome.

Always preferred the speedmod kernal from the days of Litening Rom 4. Installed the kernal on Revolution rom, still testing and from the feel of it, feels much smoother than the stock since I also have the SGP glass shield. Found it little snappier too than the stock.

I too found the color saturation a bit dull to my taste would prefer little more saturation or stock setting in regards to the same. However found the screen wee bit sharper than the stock.

Is there anyway we can have the stock color settings back hardcore? Also, any specific reason for not supporting boot animation.

Thanks.

[Galaxy S II Original Android Development] russell.nash:
Hi hc,

I found that K2-1 cannot be flashed with CWM-Tool. I tried several times but failed. Then I tried with Odin which worked. This is the first time this happened. If you try to flash the tar and it gets pre-extracted by CWM-Tool it does not start to flash. If you extract the bzImage yourself and flash it you find out that it still has the old kernel after the reboot.

Just FYI.
[Galaxy S II Original Android Development] :
I didn't have any problem with cwm app flashing!
[Galaxy S II Original Android Development] moro30:
@hardcore

Please can you make a CWM zip version?? :D

Sorry but this rom is useful to set the screen off? stability is compromised if you do not set the screen? i used 200-500 with set cpu, it is correct? battery consumption rises if you set the screen-off?

Been playing around with SiyahKernel for the past week or so, but was itching to try out this latest iteration from hardcore. Wow, very, very smooth, I must say! And apparently, my back soft key is working again even with my Glas sp still on. :) only smallie is that during charging (old known problem with Glas sp), the screen is still less responsive, like before.

[Galaxy S II Original Android Development] Tyrol:
Just wanted to check if I'm the only one with this quirk.

I was running a CWM backup and noticed that there is no progress bar animation! I'd backed up before I flashed, on CF-Root, & there was a progress bar animation. However, after flashing SpeedMod T2-1, there wasn't a progress bar during CWM backup. It happens both when you do a backup from the CWM app and when you do it from Recovery mode. It gives the illusion that nothing is happening and that your phone died or something, but if you wait (with bated breath), you see that it's actually working through the text updates. Just without any visible progress.

Anyone else got this as well?
