Siyah 2.6.4 with Turkbey v30.1

Wow, wow, wow, 2.6.4 is my new daily driver. This one is a keeper for sure. Battery life and performance are unbelievable right now. The PPL with battery life issues should really learn how to tweak their phones for their own usage. I don't see how any other kernel would perform better when I have so many options at my disposal. So if you have battery life issues then blame your inability to configure this kernel to your usage.

BTW, I am saying this with my phone OCed @1.624Ghz, UVed, & tweaked for my usage and I am very happy right now. I don't know what else is left until we get an ICS daily driver ROM.
[Galaxy S II Original Android Development] JmPTaz09:
I too am getting great performance and battery on 2.6.4. I'm at 200-1200 conservative governor with no added scripts. Fast enough for me (everything is almost immediate) and still at 66% at 6:30 p.m. after slightly low to average use off charger since 8:00 a.m. prolly won't change kernel or rom (unnamed) for awhile as this is running so well!
[Galaxy S II Original Android Development] stevehkim:
i too agree @ 1.4 ghz siyah 2.6.4 is awesome. ondemandx and only scripts im using arr s98siyah thunderbolt and s70darky zipalign. with some deep uv'ing.

tweaked - by me

kernel - siyah the og

rom- me you eeee.
[Galaxy S II Original Android Development] pikachu01:
Try installing the main CWM?

Yup. I PMed gokhan about that. Interactive type governors seem to lag with graphics. For now, I'm using ondemand and having no problems with it.
[Galaxy S II Original Android Development] marcusjt:
2.6.4 is excellent, apart from that I can't delete files in any of the file managers I have... :(

I had the same problem with an earlier kernel, though don't remember which, and didn't have it with the previous one I had installed, which was either 2.6.2 or 2.6.3...

Any idea what's causing this? Is there a quick fix? Or is another kernel release needed?
[Galaxy S II Original Android Development] barondebxl:
Hi people, I'm trying to download and install the kernel directly from my phone but it keep saying "download unsuccessful". I did check install from unknown sources in the settings and I tried downloaded the zip file and it's not working. I tried the tar also but still "download unsuccessful. Help thanks!
[Galaxy S II Original Android Development] stevehkim:
you need to use a different browser. either dolphin or opera work well for downloads.

Does Siyah 2.6.3 supports CM9???
[Galaxy S II Original Android Development] goldman11:
Hey.

I am using the latest 2.6.4 siyah with the latest CM7 nightly build.

I seem to have a battery drain issue, I am loosin.g about 3-5% every 5-15 mins just from surfing.

I am down from 100% to 37% from roughly 3 hours of mostly surfing. Edit : rebooted and it went down to 13%

Is this normal or am I not doing something properly?

could it be a problem with the nightly build?

Thanks
[Galaxy S II Original Android Development] Shinfei:
No, it's not a kernel for ics, no sources yet.
[Galaxy S II Original Android Development] ggogolewski:
You may use app from market "download all files" to fix this problem. It works on stock browser.

[Galaxy S II Original Android Development] brack11:
Known issue, you can install from market app called downloads (It maybe a variation) and that app will help you download files via stock browser.

Hehe, was a bit late with advise :-)

[Galaxy S II Original Android Development] Rockin_Zombie:
I am having some difficulty with using voodoo louder. I have wajkIUI (MIUI mod) rom with siyah 2.6.4. The driver installed without any problem, but the slider doesn't seem to be enabled. I can't slide above 0.0 dB in voodoo louder app. My limiter is set to highest i.e. 6 dB. Am I missing something?
[Galaxy S II Original Android Development] MistahBungle:
Given your question is about an app rather than the kernel (I'm using Louder on Siyah 2.6.4 & it's working *flawlessly* btw), shouldn't you be asking this question in the Louder thread :confused:

[Galaxy S II Original Android Development] sayatsugu:
Hi Pikachu,

I have installed your Thunderbolt! and screenstate scaling scripts as according to your instructions. Everything flashed well and checked with File Explorer to ensure the files are in init.d

I then ran the scripts with mounti9000 as mount success but for sqlite_optimize I get a busybox not found error. Is that supposed to be the case or do I need to find a way to install a copy of busybox ?

I'm currently on Siyah 2.6.4 (pure awesomeness, thank Gokhanmoral !) with your Thunderbolt! 2.3.5 and screenstate_scaling 1.4.5 with Ondemandx and SIO.

I'm a bit lost as to choosing Ondemandx or Lulzactive now as I read that the interactive governers are experiencing graphic lag issues ?

Thank you.
[Galaxy S II Original Android Development] Simba501:
Is there a reason why you're using bfq? I think there are better options. Svnet Dormancy is a little high; might want to look into that. It's caused by data transfers, which wake the device. Find out which apps are pulling data when the screen is off; maybe review refresh settings of those that do. IM apps (other than Talk, which is excellent) typically cause this, but it can be something else.
[Galaxy S II Original Android Development] mavixda:
Please! can tell you what i / o scheduler to use with ondemadx?

Thanks Gokhanmoral

Gokhanmoral, thanks for your hard work!

Your kernel is near perfect now, it's a piece of art :)

I have a suggestion if i may. ICS is just around the corner, and when the kernel sources finally become available, please use your skills to repeat this amazing work for ICS!
[Galaxy S II Original Android Development] :
kinda having a small problem with the latest update. seems that it saves my frequencies when i undervolt but when i put my cpu clock to 200min and 1600max it reverts back to stock cpu clock frequencies. i use Voltage Control. reflashed kernel, tried reflashing the rom i am on just incase i did something wrong and i just can not find the solution...:( any ideas anyone please

Just got a question just..how can i decrease/modify the screen brigtness?

For me its too bright unlike the brightness setup in 2.5.2b..Is there any script to lower it.. I dont use auto brightness and my brightness was at tge lowest level but its still too bright for me especially at night..

Thanks in advance..
[Galaxy S II Original Android Development] :
no problems here mate i downloaded it from market and works fine. my bloody problem is with voltage control..when i try to overclock it seems that it does not want to keep the cpu clock frequencies that input and reverts back to stock....but all my other settings stay apart from that and it kinda annoys me

use deluxe settings.. at the bottom there is brightness settings you can play around with

Hi, I'm having a major problem. My screen goes into a fuzzy blur with white lines running across horizontally and becomes unresponsive. Even the buttons do not respond. I've already tried raising the GPU frequency to no avail.

Secondly, how do I adjust pm_hotplug parameters? I've tried modifying them in sys/module but they revert to stock after a reboot
[Galaxy S II Original Android Development] Rampler:
I have problems with VC, every time a reboot my UC settings are gone.

What i have already done:

- Deleted all files in init.d

- Dalvik and cache wipe

- reflash kernel many times

When a flash 2.6.2 again, vc is running with UC.

Any Ideas ?

In your /etc/init.d folder do you have a script named S91voltcrl? (or something like that)?
[Galaxy S II Original Android Development] Rampler:
Yes i have !
[Galaxy S II Original Android Development] bullemina:
I have the same problem with 2.6.4.

EDIT: Scheduler and frequency is not saved after reboot.
[Galaxy S II Original Android Development] Rampler:
If i change the governor or the voltage settings, vc will remember after reboot. Only the clocksettings (max frequency to 800) will not be set after reboot.

VC says after reboot "unsaved setings" (where normally is the word "default")

Ideas ?

Then i would say, it seems to be a bug ....

But if it is a bug, many others should have the same problem
[Galaxy S II Original Android Development] droidphile:
@All who are having problems settings not sticking on reboot (VC or your own script). Solution has been discussed innumerable times in the thread.

Simply edit the script generated by VC and add "sleep 20" after the first line (which invokes sh or busybox shell).

Also give full permission to scaling_max_freq file before echoing value into it, and change permission to read-only after values are echoed. The 3 lines should look something like this:

chmod 777 /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

echo "1400000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

chmod 444 /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
[Galaxy S II Original Android Development] iamsmallpang:
Sorry..i don't know how to edit

what step can i do?
[Galaxy S II Original Android Development] droidphile:
Use Script Manager from market to edit the script.

Find the script generated by Voltage Control in /system/etc/init.d. Mount r/w in that directory using Root Explorer. Also change the VC script's permission to rwx for owner group and others.

Now open the script using Script Manager, do all editing, save.

Run as root (using script manager itself) to make sure there are no errors in the script. If everything went well (exit code=0), from next boot your UC/OC/UV settings will be persistent.
[Galaxy S II Original Android Development] Rampler:
Maybe i am to stupid for that:

I edit via root-explorer the S91voltctrl file. After that save changes. Root explorer tells me, that the file is saved and the the original backuped under ...

But when i reopen the file i doesnt see my modified lines. What is wrong ?
[Galaxy S II Original Android Development] droidphile:
Do not edit using Root Explorer.

Use Root Explorer to only mount r/w for init.d directory and change the permission of script file itself to 777.

Use Script Manager to edit and save the script.
[Galaxy S II Original Android Development] cmd512:
Just curious, but why not use root explorer's text editor? I've been using it forever to edit my init.d scripts directly, and my changes stick with no problems. Furthermore, all edits do get properly pushed to the appropriate sys files.
[Galaxy S II Original Android Development] Rampler:
OK i tried it. The permission bits are set to 777, no problem, so far.

I used the SM to edit the file, hit the save button. Then i hit the back button, now i get this message:

file modified

File has been modified, do you want to update it ?

Now i press ok.

I see for one second the message: unable to copy

Sorry for your cirumstances
[Galaxy S II Original Android Development] droidphile:
Because chances of leaving an extra space or so which will cause failure to execute the script, are more with root explorer editor.

With script manager, it's easy to check and tackle by running as SU.
[Galaxy S II Original Android Development] legionxx:
hi guys, quick question.. can i just flash thunderbolt 2.3.5 on siyah 2.6.4 without using script manager to edit (cos i'm noob) and get better batt and performance out of it?

ps: siyah, one kernel to rule them all... true story :)
[Galaxy S II Original Android Development] Rampler:
THANKS !!

I have it, my problem was, that i forgot to mount via root explorer r/w.

I thought the script manager can mount it by himself with r/w.

Now my vc sets the uc correctly after boot. (I have only added sleep 20)

For me it is a temporary solution, every time a change the values via vc, i have to edit s91volt file. Hopefully this will fixed through vc in future.

2.6.4 = FROM 100% TO 0 = 12h

2.6.2 = FROM 100% TO 0 = 24h

:confused::confused::confused::confused:

Reinstalled 2.6.2 :mad:
[Galaxy S II Original Android Development] gokhanmoral:
no way!

this is just a misleading post.

come on! I am not only the developer but also the most loyal and active user of this kernel and I nominate this post as the dumbest post in the last 10 pages.

12h vs 24h?

using what? doing what?

how can you make sure that the usage patterns were the same?

I can deplete the battery with v2.6.2 in 4 hours and make v2.6.4 last 24h+ with my heavy usage.

I don't feel any dramatic difference between v2.6.2 and v2.6.4 and I verified it by comparing the sources. I even feel that v2.6.4 is better in terms of battery life.
[Galaxy S II Original Android Development] pikachu01:
Hmm 2.6.1 is better in terms of battery and performance? I seem to think 2.6.4 is still the best :/

Try using SIO as the I/O scheduler.

Choose Ondemand instead. OndemandX seems to be slower in taking calls. :/

And remounti9100 is the correct remount :S

Gokhan should consider applying newmail's patch here for ondemand:

http://xdaforums.com/showthread.php?t=1266051

SIO.

It's normal. :)

Report the problem to the app developer. He will be interested in fixing it for you :)

Did you install an app that keeps waking up your phone recently?
[Galaxy S II Original Android Development] xavihernandez:
It's just a feeling (no real stats) but I agree with you about battery drain. My best results about battery was with 2.2b15 and 2.6.2. Both with ondemandX and around -25mV for each step.

2.6.4 seems to drain battery faster. I don't know about performances (I got the feeling 2.6.4 is better since it's the last one and people giving good feedbacks).

Anyways I wanted to share my impressions.

Thanks again gokhan for this great kernel!

EDIT : when I say faster it is not that fast as you of course lmao. It's the reason why I said that it's a feeling.

[Galaxy S II Original Android Development] lpsi2000:
5% every 15 minutes is not normal unless you are doing some heavy downloads during that time (like applications update from the market, or big downloads). Because surfing the web does require reading the stuff you are surfing and I don't drop 5% every 15 mins while surfing.

That is bullsh*t, there is no way with the same usage you get 50% less with 2.6.4.
[Galaxy S II Original Android Development] adivorandroid:
Same usage with 2.6.2 and 2.6.4. No app added or removed.

I wait 2.6.5 for future test.

A minimum configuration of ThunderBolt! is in Siyah. To get the full experience, you have to flash the CWM zips in ThunderBolt!'s thread.

This is with or without ThunderBolt! ?
[Galaxy S II Original Android Development] ndnesh:
I have been using 2.6.2 for almost a week now and have no problems with it... but as soon as i updated to 2.6.4 , the screen brightness got screwed up... i could see lines on the right hand side of the screen(top right and bottom right) and the left side of the screen was quite dark... this was not so with the 2.6.2. i did not try the 2.6.3.

I have checked the changelogs but there was no mention of any changes to any display parameters.

What changed? I really loved the look of the 2.6.2 with the clear screen ... can you please look into this??

Also, i dont use any scripts, just use the kernel as it is. :)
[Galaxy S II Original Android Development] thecrater:
Hi, I've just read the features log again and noticed that the Siyah kernel includes the

Thunderbolt! script. Does this mean that I do not need to flash the cwm version available in the other thread?!?
[Galaxy S II Original Android Development] goldman11:
alright thanks good to know its not a issue on my end,ty for confirming it too pikachu01.

I managed to get 4 hours of straight surfing out of it I guess thats pretty great actually.

btw I was surfing/downloading/using apps at the same time mostly so I guess its understandable the amount that drained, I just wasn't sure if its normal since I only have the phone a week or 2 now loving every bit of it though :P

overall love this kernel works very fast and stable.
[Galaxy S II Original Android Development] Hertz33:
This is without any scripts.

The Kernel came with the ROM, this is with some medium UV and no UC.

Can you try ThunderBolt! and see if it saves battery for you?
[Galaxy S II Original Android Development] :
Right sorry guys to ask these questions but i just need some peace of mind thanks.

Firstly i am on a new base KL1 and i set everything up thunderbolt scripts and my voltage control settings. Now before anyone says read few pages back, i already have done that and i want to thank Droidphile for the tips. But what i want to know is if i do not want to change the cpu clock frequencies and leave them stock that is fine correct? i mean it still saves all my settings on boot ie governor change and scheduler and it even saves my Undervolting settings. only thing that does not save is when i use to overclock...will this be fixed? has it got to do with Voltage control app or is it something to do with what rom we use? cause when i reverted back to KK5 it worked fine....Sorry just for peace of mind and nothing else really

And regarding battery life...2.6.4 is the best so far i tried for Siyah...5hrs screen on time and that is with very heavy usage
[Galaxy S II Original Android Development] xavihernandez:
@pikachu01

I do not use your scripts. I may will have a look at it. I only change some things with SetCPU/Voltage Control.

Only xda and dolphin were running..so maybe i have a problem with my phone since first day ? Or my battery loss is normal ? (Brightness is set at 1/4)

Is it a sensible request to change the Wifi drivers so they ignore all the non-ARP broadcast/multicast packets for all other protocols? This increases battery life significantly on dirty networks...
[Galaxy S II Original Android Development] goldencore:
Hi!

With Siya 2.6.4 and Thunderbolt scripts I have problems connecting to my home Wifi. Sometimes it connects then disconnects, sometimes it doesn't find the AP at all althought I am standing right next to it. I reverted my Nandroid backup (Kernel 2.6.2 and no scripts) and the problem is gone.

Now with 2.6.4 without Thunderbolt it also works. So I would like to know if there are any Wifi related lines in the Thunderbolt scripts which I could delete to solve the problem and still use the rest of the Thunderbolt scripts.
[Galaxy S II Original Android Development] pikachu01:
I think I know what this problem is. You installed ThunderBolt! into a /system that is almost full. People will get wifi issues when your overflow your system partition. Try doing a fresh install then remove some apps before flashing ThunderBolt!

i have to manually create one? ( i can do that in system folder ? )

or what other options do i have to place init.d scripts.

really my first time playing with my kernel , been on speedmod and trying siyah now.
