Yeh, no uv, no uc, no oc, ov, same for me.. but still yesterday i had 2-3 freezes. been only 1 day since I've been using the kernel soo...
[Galaxy S II Original Android Development] VFO:
I am using the default 200Mhz-1200Mhz scaling so I don't know what I'm missing here. The only time I really notice the choppiness is when I'm using quadrant or scrolling on web pages or forums such a this one. Other than that the phone seems really smooth and battery life has been impeccable. I haven't tried any graphically challenging games yet to see if there is choppiness so I can't attest to whether it happens then or not. For the record I am running the UnNamed 2.2.1 ROM with no scripts other than the Darkys zip align script with your settings. All in all really excellent kernel.
[Galaxy S II Original Android Development] stevehkim:
I believe gokhan will be fixing the bugs from 2.6.3. Starting off with a new year with 2.6.4 the perfect kernel!
[Galaxy S II Original Android Development] DannyDrama:
This kernel works perfectly, and.fixed a few bugs I had before.

[Galaxy S II Original Android Development] hausmanis:
with 2.6.3 my phone runs super smooth and my old CPU UV settings works good again, altho i cant say the same about my GPU UV.

im using 100 at 1000mv

and 160 at 1100mv

What GPU speeds and Uv are you guys using ?

EDIT: Oh and btw happy newyear to Gokhanmoral and all the Siyah fans!

I am having a problem with the new CWM, i was trying to install a new radio, but it fails: assert failed:getprop ("ro.product.device") =="galaxys2" || getprop ("ro.buid.product")...etc, anyone knows whats apening??
[Galaxy S II Original Android Development] :
hi guys,

I bought this phone this week and and so far I just rooted, flashed checkrom v4 and this kernel on it(still a noob so dont want to mess things up).

a couple of questions though:

1. battery wise, which kernel is the most battery friendly?(I can test it alone but it will take weeks and I guess some of you checked it out already).

2. in what aspects can the ThunderBolt tweaks improve my phone? I already find it fast and smooth enough(my first smartphone) but if it helps a lot then how hard is it to flash it as a newbie? \:

thx
[Galaxy S II Original Android Development] wurzelsepp3:
I use 160 267 300 @ 850 950 950mv

Your GPU voltages are way too high for your clockspeeds so you waste allot of battery. I suggest 850 and 900mv

[Galaxy S II Original Android Development] xcarecrow:
I've flashed the thunderbolt and the screen scaling zips after 2.6.3, but the governor doesn't change after reboot, its ondemand again and bfq scheduler. I am with checkrom rom v4 and it has some other scripts in the init.d folder. I've opened the scripts of thunderbolt and i see zipalign scripts and some other things that i think are included with checkrom scripts. Should i delete all scripts from checkrom and only left thunderbolt? i must config the scripts of thunderbolt with any values to take effect? because i see no governor selected inside.

Please Pikachu or someone else, can answer me these questions?

thanks in advance.

And where is suposed i can change the vdd_tables voltages in system tuner aplication? because i can't see where.
[Galaxy S II Original Android Development] ziroxs:
I use 100MHz/800mV and 200MHz/900mV for my GPU. I did not need more. ;)
[Galaxy S II Original Android Development] hawkerpaul:
For some reason this new cwm version returns a blank when issuing a getprop command in a script so any testing of firmware version etc.is doomed to fail.

I've pm'd gokhan on the matter.

I don't like this version of cwm. You can't even use the home key to make a selection but forced to use the power button instead. Much prefer 5.0.2.7
[Galaxy S II Original Android Development] :
in 2.6.3 the gpu voltages on boot don't works
[Galaxy S II Original Android Development] KcDaRookie:
@hawkerpaul: yeah this is somehow annoying pressing the power button ^^

@hausmanis: look at the script in my signature, runs perfectly smooth, no need for ocing the third step.

@bartit: can't confirm that, my bootscript changes gpu voltages and frequencies as it should

@all: init.d gen 2.6.2 is available and will let you change almost every possible value siyah kernel offers!

feedback is appreciated.

see ya next year guys ^^

Happy new year to everyone! And a MASSIVE THANKS to everyone who's been involved and helped with SiyahKernel over the last few months! :)

It's been an awesome ride, and I think there's more to go till the story ends too! :)

I had a question, but sod it. It can wait till next year! :D
[Galaxy S II Original Android Development] a1exander:
Happy new years! :DD Im on vacation right now so I dont know if I can safely flash 2.6.3 without brick. Saw other people getting phones bricked. So I think ill wait till i get home where I can access my computer. ;)

Thanks for great work on this kernel!
[Galaxy S II Original Android Development] stevehkim:
its the new cwm 5.5 people are having some issues on i777 siyah thread. kernel should flash fine. but flashing zips after that arent supported by the new cwm will cause issues.

ICS Rom and kernel is Released, Hope to see this fantastic kernel Getting ICS update Too...!
[Galaxy S II Original Android Development] a1exander:
I installed the new miui update today and was surprised to see how smooth scrolling is with official miui kernel. Is official miui kernel better for miui or maybe it was better performance in the new miui update?
[Galaxy S II Original Android Development] gokhanmoral:
I've just flashed 3 different version of modems which were in my sdcard (using CWMManager app) and I had no problem.

then I flashed them again by manually rebooting into CWM recovery and selecting them, I had no problem neither.

it may be something else (bad download?) or I was lucky?

I doubt that flashing modems with CWM manager will brick a device because it only writes the modem to a block device.

EDIT: I will revert back to old CWM recovery in v2.6.4 just to clear that doubt.
[Galaxy S II Original Android Development] Vaedryn:
No, dl is not corrupt , after switch to 2.6.2 the same modem file works.

It come a long error, ( getdrop ro.product.build ..... And more ro.product ) and at the end error 7

i will look tomorrow what the error say.

I dont use cwm manager , boot direct in recovery.

But no problem , new modem works ,than back to 2.6.3

Edit: have post a part of the error.

[Galaxy S II Original Android Development] VFO:
I was able to successfully flash a couple of zips without any issues. I did notice one thing though, it seemed to take a bit longer than usual to flash But it worked just the same. so far I have been super impressed with the work that has been done on this project. Thank you so much gokhanmoral for bringing this kernel to the SGH-I777 community and making this phone better. Happy New Year! :-)
[Galaxy S II Original Android Development] gippy2:
Lol after updating to 2.6.3 I decided to use the siyah cleaning script for the second time, then couldn't use any buttons in recovery to install or reboot. Had to adb reboot then flash from cwm app. Anyhow Happy New Year to you all.
[Galaxy S II Original Android Development] Upy3r:
Well I dont want sound mad... but after install 2.6.3 the backup/restore is ****ed-up.. I install this version to get the Voodoo Louder.. so i make a new backup and delete the old one.. I dicide try another rom just for test something.. and when i wnat to come back its says Cant restore system.ext4 so... 5 months with the same rom, modyfing Frameworks.. and trying to make the more stable as posible.. gone.. nice new year gift.
[Galaxy S II Original Android Development] mavixda:
same here :confused:
[Galaxy S II Original Android Development] poochewer:
I found if you use bfq/ondemandx the choppiness goes away. I feel that its caused by lulzactive
[Galaxy S II Original Android Development] minidou-77:
Are you on Hyperdroid rom ?

I had the same problem while trying to flash a JKay theme.

I reflashed the rom (which is wipe) and all cleared ;)
[Galaxy S II Original Android Development] blk15:
Not too sure if this is an 'old' issue. But I am having issues with 'usages' displaying voice calls for the amount of time my phone is turned on.

Has anyone got a remedy for this? This is on the siyah 2.6.2
[Galaxy S II Original Android Development] z2k:
Hi Gokhan, any chance you can revert to CWM5? 5.5 seems to have added more issues(mounting and installing zips) than improvements.

Great kernel btw, looking forward to 2.6.4.
[Galaxy S II Original Android Development] JmPTaz09:
I too am using on I777 variant, please keep releasing those versions as well. 2.6.3 has been working great for me all day, lot's of text/call and almost hour of GPS, battery still going strong, on lulzactive with sio, 200-1200. Happy new years, thanks for the kernel!
[Galaxy S II Original Android Development] timberwolf60:
No problems on me excrpt select button changed to power buttom.
[Galaxy S II Original Android Development] age9990:

[Galaxy S II Original Android Development] radicalgel:
Happy New Year Gokhan

Thanks for this awesome kernel! Have a great year!

Quick update on my 2.6.3 experience. I too, like a lot of ppl here, flashed this just to try out lulz + pikachu's settings and also to try out LOUDER! LOUDER works really well but I have reverted back to 2.6.1 which is super smooth for me with BFQ and Conservative. Lulzactive causes major lag when flicking btw homescreens or scrolling fast through contacts. Also, as Gokhan mentioned, 2.6.3 hasn't been cleaned up so it will cause faster battery drain. I also notice a lot of bugs with the new recovery and I hate having to press the power button instead of the home button to select stuff. Hope all this will be fixed in 2.6.4. In the meantime I'm super satisfied with Criskelo v35 + Siyah 2.6.1 + Geko OC/UV + Audio Tweaked (Check my sig for more details).
[Galaxy S II Original Android Development] :
i use voltage control for make my own cpu settings.

i have the voltage control script in the init.d folder.

all settings are correctly loaded except the gpu voltages.

in versions previous to 2.6.2 all settings (including gpu voltages) are loaded, but not

for versions >= 2.6.2 (including 2.6.3)

plase, you can confirm that your gpu voltages are correcly loaded displaying the

/sys/devices/virtual/misc/gpu_voltage_control/gpu_control

file?

thx
[Galaxy S II Original Android Development] gokhanmoral:
I could reproduce that with voltage control app and I fixed it in v2.6.4
[Galaxy S II Original Android Development] b2rdetor:
i wrote about it some pages ago, but may be my post(s) are ignored ))))

also wanna ask some other questions:

1. what GPU freqs are available to set via init.d (i can sucsessfully set it to 40mHz - it can run interface smoothly but games want more performance)

2. which minimal CPU\GPU voltage we can set via scripts (seems like it 800mV???)

[Galaxy S II Original Android Development] :
Is there anybody else thats using the lulzactive-app and cant see any difference in his phones behaviour? I´ve been using it for some days now and no matter how i change the settings, i cant see any difference in battery drain or speed whatsoever.
[Galaxy S II Original Android Development] alcurtis93:
na definately notice a difference if I play with sample times. If it put it too much battery saving the phone lags big style
[Galaxy S II Original Android Development] :
Then why doesnt this happen to me? Even if i put everything, and i mean EVERYTHING on max. Batterysaving i'm still not encountering even the smallest lag...
[Galaxy S II Original Android Development] :
Guys may I suggest something?

Some experienced user might open a thread just like droidphile did and post results about battery life with different governors and tweaks applied to the same. That would be useful as a starting base, provided that every phone is different for installed apps and pattern of usage!

Good idea mate :) we could establish a shared testing environment with the aid of the experts here and then do some test (user it_Ler did this many times with speedmod and void kernel, have a look in their threads to get the idea). I find these tests rather useful, but I miss a total screen on time report.

Cheers mate

[Galaxy S II Original Android Development] mavixda:
problem is not the "button change", which you can find yourself. (home button and power button. do not matter).

Problem is, if you want some flash (eg modem) get error message. I have tried allaes, with all cache cleared and all. but that does not help. (internal or external SD do not matter). I think that is important bug. :(
[Galaxy S II Original Android Development] droidphile:
Tweaks can not guarantee a weighted and exact battery life. Reasons includes what you said:

1) Different usage pattern

2) Different apps installed, so different background apps and processes run. (i mean, it doesn't make any sense to complain about battery drain for ex with 3g enabled and chat in facebook app active)

3) If someone misinterpret the tweaks or fails to apply them correctly, there will be lot of questions raised like "i'm not getting X hours screen-on like you said".

'Tweaks Threads' are for us to experiment with values after we get a fair idea on how to go about battery-saving or performance. Even CPU/GPU grade might decide on your battery life and/or stability. For ex: My GPU can hardly take any UV.

Anyways if someone wants to post battery-life results with tweaks, they better get prepared to answer "why am i not getting that much".

I mean, we should be proud that we own a powerful & performance-packed phone and use our free time to plugin and recharge; without worrying about benchmarks/infinite screen-on time as long as the experience is smooth :)
[Galaxy S II Original Android Development] ante0:
Any way to revert to older Cwm? Newest one in 2.6.3 is kind of buggy. Can't mount ext sd, no progress bar. Power button is now select. Which also acts as back if Back gets disabled, and to manually get to recovery you now have to hold down home, vol up and power. I did not know thus so I thought my recovery borked after flashing a test rom.
[Galaxy S II Original Android Development] droidphile:
Gokhan will release 2.6.4 soon which will have the older cwm. Let's wait for it
[Galaxy S II Original Android Development] ante0:
I should've scrolled up. xD

Thanks for answer though :)
[Galaxy S II Original Android Development] Hertz33:
OK the Power button is now select :confused: ,didn't quiet catch that.

Got a little nervous and reflashed the 2.6.2 via CWM software wich is more battery friendly anyway. I'll wait for 2.6.4 wich suppose to fix the battey drain.

the drain wasn't really bad but faster then the privious version.
[Galaxy S II Original Android Development] KennyLegend:
Wait for 2.6.4 guys ... Come on...

Gokhan already posted 2.6.3 isn't perfect and will try fix the known issues for 2.6.4.

All of them have the same battery life for me :p no difference between all of them....can someone prove me wrong ?
[Galaxy S II Original Android Development] pro.aggro:
My settings made with Voltage Control aren't saved and not set as boot settings.

Everytime i reboot MHz is set to 100-1200 although i set it to 100-800.I save this in the VC profil (Apply) and then go to menu >> save as boot settings.

When i take a look at the S91voltctrl file in /init.d the values are right (100-800MHz)

Any idea?
[Galaxy S II Original Android Development] VFO:
You have to exit VC after hitting apply then go back into the program and then go to menu/save as boot settings. For some reason VC needs to be closed out an re started prior to saving as boot settings. Hope this helps.
[Galaxy S II Original Android Development] pro.aggro:
No way.

When i reboot and restart VC the profil is named "Unsaved Settings" and MHz is set to 100-1200MHz >> mix from my settings (100MHz is min) and the Default settings (max set to 1200MHz)

v2.6.2 is positive and then

v2.6.3 maybe negative

wish v2.6.4 can improve it

If I am not totally wrong 2.6.4 is already there. Folks, check the homepage given in the first post of this thread.
[Galaxy S II Original Android Development] XDA mark:
2.6.4 is on the site, but there are no download links yet on the page. At lwast thats what I see.
[Galaxy S II Original Android Development] giorgosaero:
Guys can someone sent me the perfomance mod zip for 2.6.2?
[Galaxy S II Original Android Development] pikachu01:
Ahh, in that case, use OndemandX?

Are you 3 using Orbot?

Ahh, I find that lulzactive does lag in terms of graphics (as well as smartassV2 and interactive). It doesn't scale the graphics well (maybe a bug in cpufreq that affects all interactive based governors)? This is very visible in some apps and Quadrant. (I just tested).

You need to test them yourself :) Some swear by some kernels and others don't.

ThunderBolt! improves the battery life aspect as well as performance. :) Read the original thread for the "features" to know more. :)

You need to use Voltage Control to control the governor/scheduler. ThunderBolt! doesn't set the governor/scheduler by default (as preferences for both fully depends on the individual). You should delete them (or better yet, upload it here so that I can see it :)). The voltages can be tuned in Voltage Control.

You need to update the updater_binary with the newer one (You can get it from the 2nd post of my ThunderBolt! thread).

CWM5.5's backup/restore isn't reverse compatible :( Reflash 2.6.3 and then restore from there.

Yes. The choppiness is visible for apps that need graphic scaling. The interactive governors doesn't seem to scale well when using an interactive governor. This doesn't happen with i9000 kernels. It might be due to the cpufreq code change?
[Galaxy S II Original Android Development] stevehkim:
pika i noticed you updated your scripts. will this fix the graphics scaling if using lulzactive?
[Galaxy S II Original Android Development] aqualeris:
Currently on 2.6.1 + battery.zip and it works flawlessly. Battery life was never better. But I'm confused about the newer versions where it says there is no longer any need to flash these scripts. Why? The battery script should technically still work if I choose to flash it with the newer siyah versions right.
[Galaxy S II Original Android Development] xuxuzao:
i tried to install thunderbolts screenscale_state with miui and siyah 2.6.2 and cel doenst boot

why not?

if i switch to 2.6.3 or 2.6.4 would it work?

thanks!
[Galaxy S II Original Android Development] stevehkim:
its because those zips are supported by the cwm in 2.6.2. use 2.6.3 and reflash. should be gtg

miui+siyah = beast
[Galaxy S II Original Android Development] stevehkim:
2.6.1 is my bread and butter. absolutely flawless. gonna test 2.6.3 all day today and get back to u. pika seems as though its lulzactive governer. i applied your new scripts and tried tests. its better but the choppiness is still there. ondemandx on 2.6.3 is smooth just like 2.6.1.

miui+siyah = beast
[Galaxy S II Original Android Development] aqualeris:
Indeed, 2.6.1 is running really smooth and together with battery script I'm getting the best battery life amongst all the kernels I've tried. Standby times are particularly good. Or maybe it's just because I've recently switched from GoLauncher to TW (golauncher is said to drain battery) but whatever it is, loving 2.6.1 and I foresee myself sticking with it for quite some time.
[Galaxy S II Original Android Development] fusionjack:
Does someone experience cpu freq stuck at 500 MHz?

I reproduced it today as I was using skype and then I noticed the lag. As I saw in cpuspy, the freq stayed at 500 MHz the whole time, even after using skype.

I was using miui 1.2.30, siyah 2.6.3, lulzactive, sio and thunderbolt scripts. Now I'm on siyah 2.6.2 with ondemandx.

I didn't test ondemandx on siyah 2.6.3. But anyway I'm using 200-1200 MHz again as I read a post that someone did battery test and stated that battery consumption in 200 MHz is better than in 100 MHz with same voltage.
[Galaxy S II Original Android Development] stevehkim:
@ Pikachu. Your zip to revert back the changes for cm7/miui i900 worked perfectly for my i777 att sgs2!! Thanks. maybe you can change the name to cm7/miui i900/i777.

[Galaxy S II Original Android Development] arcmanov:
Total noob question:

I just flashed checkROM and the Dark Knight 2.5.2 kernel, and then I came across this thread.

I would like to flash it, but I have no idea what these 'scripts' are, and what they do, and I'm hesitant, because I'm afraid I'll mess up something important and brick the phone. :confused:

Is there anything important I need to do after flashing this kernel?
[Galaxy S II Original Android Development] z2k:
Not with 2.6.3.. You can just flash it and it should be tuned to battery savings..
