I am using MIUI rom and install this kernel . Working awesum so far ! . However i want to try out some ICS based roms . I read in the FAQ that siyah kernel does not support ICS roms .

Now can i install any ICS based rom in recovery ? or i have to 1st flash some ics compatible kernel ? and then flash the ICS rom ?

Please help me out here .

[Galaxy S II Q&A, Help & Troubleshooting] CamoGeko:
Read the instructions of the ROM that you want to flash mate. Flashing it with Siyah in recovery is ok, but most likely that it wont boot unless you flash a compatible kernel straight after.

has anyone else here been having problems with the lulzactive app? i really can not get it working:( i do everything right i set it on boot. when i reboot i leave the sod for at least ten minutes to boot up and when i go into the app it reverts back to default settings...any work arounds to it? or do you advice to use scripts if i want to play with the lulzactive governor?

Thanks guys
[Galaxy S II Q&A, Help & Troubleshooting] bleuxeon:
First : stop using old kernels!!! use the latest one...

Lulzactive isn't anymore a golden governor.

Ondemand as been merged with OndemandX and actualy deliver strong perfs and good battery life.

Conservative governor is now LESS battery saver compared to Ondeman, but it help to avoid lags during hardware accelerated games/benchs etc...

I suppose here that : you do not overclock, underclock, use any init.d script, use any CPU control apps etc...
[Galaxy S II Q&A, Help & Troubleshooting] Scoman:
I also noticed the same problem that you write.

It's true that the ondemand and conservative governors have been improved in the last releases, but since siyah 2.6.4 it was very useful and easy to customize lulzactive according my needs :(
[Galaxy S II Q&A, Help & Troubleshooting] lsv-1:
I've been using it for a couple of days now, so far so good, I would recommend you to check if there is an app or a script messing around the governors.

You can give it a shot to a kernel cleanup and a reflash :cool:

[Galaxy S II Q&A, Help & Troubleshooting] Scoman:
Does not work for me :(

what happens is that settings imposed using the lulzactive app by Tegrak have no effects on the behavior of the governor lulzactive on Siyah versions after 2.6.4 :confused:

Is this related with thunderbolt script?
[Galaxy S II Q&A, Help & Troubleshooting] lsv-1:
It could be bro, I just checked the lulzactive settings and they are set correctly.

Parameters are located at the following path:

sys/devices/system/cpu/cpufreq/lulzactive

Try deleting all the scripts located in etc/init.d, changing the parameters of the lulzactive app and rebooting the phone.
[Galaxy S II Q&A, Help & Troubleshooting] Scoman:
no way mate ...

When I used Siyah 2.6.4 and I changed parameters of lulzactive app for the greatest savings in battery, I watched some lag, but I could see how the cpu use mainly the low frequencies :eek:

But now, with latest Siyah, nothing will change, whatever setting I put :mad:
[Galaxy S II Q&A, Help & Troubleshooting] lsv-1:
Weird bro, for me, the app works great, all the parameters are changed in the path I previously mentioned and since I configured it for performance I can certainly notice the change, very smooth, no lag, I can get my cel on battery up to 1d 4 ~ 6 hours.
[Galaxy S II Q&A, Help & Troubleshooting] cyanoviper:
i used .12 and unfortunately it was the first version that lead to sod's for me. reverted to .11, to see wether it was the kernel (could it be something else anyways?)
[Galaxy S II Q&A, Help & Troubleshooting] lsv-1:
I can tell that .12 works great, it improves the battery consumption, however I'm the kind of person that prefers performance over battery life, I hate lag, something that changed was causing some weird lag in my desktops scrolling (go launcher ex) so I went back to .11.

Cheers! :D

Edit: I found out that the lag was caused by the combination of lulzactive(tweaked settings with app) and SIO, ondemand works good.

Everything is specific to my phone, my "normal" usage and my home location. Most values are exact results, but some are rounded. I usually have wifi, synch (three email accounts, calendar and news), Google Talk and Skype on.

For all custom kernels, I was running on Frankenstein XWLA4 ROM (Modem: XXKL1).

For Siyah, as it has many, many configurable settings, I have changed nothing - just default settings.

For N.E.A.K. I tested VR schedule, Lulzactive governor, only enabled sched_mc and the rest unchanged defaults.

Just tested Siyah v2.6.12 "out-of-the-box" and added its results.

Hmm ... Siyah v2.6.12 does not have as good battery savings as v2.6.7 (on XILA2 ROM) on my phone ... even on completely default settings (no UV, UC, etc.).

The rest is good as always ... very, very stable, smooth and highly configurable !

Sorry for answering so late ... haven't seen your suggestion to test phoenix.

Yes, Phoenix kernel is on my "kernels to test" list.

I just changed the sequence of the tests after knzo's thread was closed.

So, further development can no longer be supported via XDA, and his Phoenix app in the Market is a paid version.

As I prefer free versions, I just gave Phoenix kernel a little bit smaller priority.

SOD with 2.6.12

Hello!

I've been using siyah 2.6.12 for almost a week. It's been great regarding battery life. I got 5hours of Screen On with wifi on, gtalk, whatsapp and push email. With 3G on the battery life isn't that great but I think it's because of my carrier coverage strong signal/ really really bad.

Today I had SOD 2 times, I had them in .9 and I went back to 2.6.7 and waited a bit for this .12 version. I don't want to go back to .7 because of battery life. How can I debug what caused the SOD??

I have only updated titanium backup pro, and installed market enabler (to check if gta 3 is compatible with the samsung galaxy s2 because in my country the game is banned :( ) and 3 games (third blade, inotia3, fruitninja)

Thanks!

i create a script file in /system/etc and change the value of charge_current to 900 900 450, and the permission is correctly changed. After reboot , i find the value in /sys/class/misc/charge_current/charge_current has been set to 900 900 450,but the widget ChargeCurrent show that the current is not changed.

once i remove the script,reboot,the value gets back to 650 550 450. so i suspect if the other init setting should be done? like it is setting before my script running and the value changing doesnt mean the true value?

can you tell me how can i get the charge_current setting work?

my kernel is siyahkernel v2.6.12

the script is

#!/system/bin/sh
NEW_CHARGE_CURRENT = "900 900 450"

Siyah v2.6.13 seems to be a good version.

It is stable and smooth on my phone. Battery savings in mixed usage are better than for other Siyah kernel version, only in over-night usage, I had a little bit more drain.

Still analyzing the causes.

Overall, Siyah v2.6.13 is the most configurable kernel I have tested so far ... and I am sure that I will come back to test the configuration interface/app as well.

Gokhanmoral, you are on the right way.

You seem to be the first one publishing a stable custom kernel for ICS ... at least here in XDA.

The one which will set the new measurement for all other custom ICS kernels.

SiyahKernel v3.0beta6 feels even smoother than beta5, and has got better benchmark results than stock kernel (the only exception is Linpack).

That's the way I want a custom kernel to be.

I'm currently running Siyah 3.3.2 on stock LPG on my SGS2. It generally works well with just a glitch I've noticed. May not be kernel related but am interested if others have seen this and believe it is

GPS toggle

after "a while" (days I think) I notice my GPS gets into a state where the quick setting will no longer toggle the gps, nor will the samsung provided power widget, nor will the main setting menus.

As an aside would any hardened Siyah user care to give an opinion on either

* N.E.A.K -- picks up many off GMs changes, incorporates a few other fixes from different kernels. May be a little less stable

* Speedmod - I always used this pre-ICS and it was solid and efficient. No fancy features though and seems to stick very close to stock with few updates pulled from elsewhere

No surprise, but it seems the developers of each of these are also now working with their SGS3s (as would I!) so I'd guess development may close to stop on them. Currency with samsung updates would be by main concern

to be honest even the stock kernel on the SGS2 is pretty solid. My main uses of the alternate kernels are

- faster USB charging (ie from a power pack 450 mA -> 650 mA)

- toning down the screen brightness

- efficiency, may include underclocking, undervolting, change of scheduler etc fairly conservatively

Question on Odin Flash

Hi I have a question..

I am dual botting with Siyah.. Now I have primary ROM as RR and Secondary as CM10

Now if i have a stock firmware which i can flash via Odin.. And i flash it..

What happens..??

1.) Does Siyah Kernel's dualboot get removed..

2.) Can Odin Flash be done directly to Second ROM (Like for B2G)
[Galaxy S II Q&A, Help & Troubleshooting] CamoGeko:
Yes, if you flash any other kernel. Dual boot will be removed.

No, ODIN cannot flash second rom. You can only do that within Siyah CWM recovery.

If they dont does that mean we can flash Siyah and the second ROM will be available.. ??

[Galaxy S II Q&A, Help & Troubleshooting] Darkmind1:
Great thanks, also, I am curious about another thing. As I see, this new version of Siyah uses CWM-Based Touch Recovery v6.0.1.2. Some user has been mentioning on the forum that CWM Recovery v6.0.1.2 may have the safe erase option disabled so it wouldn't use the MMC_CAP_ERASE if it's enabled in the Kernel, but I couldn't find more precise information whether this is true or not. Now I know that Siyah Kernel itself has MMC_CAP_ERASE disabled so it's a safe Kernel, but if the recovery is now also safe (according to Entropy512's post, most ICS recoveries were not safe), it's an extra layer of safety, that's why I wanted to know. :)

i notice that the AGPS / "Use wireless networks" option seems to be broken since v1.8, and is getting much worse on v2.0.

i'm from Malaysia, a tropical country. the recent rain seasons gives a cloudy if not rainy sky, making the GPS position locking problem on AGPS all the more apparent.

v2.0 have difficulty locking when the sky is cloudy, and will not lock even after half an hour or so, with full bars of "H+" signal. tried restarting, even tried flashing to v1.8.

v1.8 seems to have slightly better locking capability, but it's only marginally better if at all.

i'm using Sygic v11.2, and did attempt to swap to google Maps, but the problem remain.

GPS / satellite signal bar in Sygic was fluctuating, but it just won't lock.
