Heyy Khan after flashing 2.6 it seems CF.lumen ceased to work.. It refused to change color temperature and after a reinstall it's stuck on retrieving location... Anyone else having this issue? o_O

thanks for 2.6 - works great on my fone.. no headaches so far :D
[Galaxy S II Original Android Development] MistahBungle:
Guys...

I've had a question from someone who doesn't have enough posts up yet to post in here.

Basically he's asking if Siyah does anything "different" with regard to managing ram compared to say a stock kernel ?

If anyone's got any info re: this it would be much appreciated ;)

After flashing 2.6. I got more battery drain then on 2.5.2
[Galaxy S II Original Android Development] BULL3TPR00F:
After flashing latest v2.6 + performance.zip im experiencing CONSTANT soft reboots after intitial boot up (before everything has a chance to load fully, about 1-2 minutes or so, soft reboot, and the cycle keeps happening). CPU starts to get warm fairly quick as well, seems to be getting overworked.

Anyone else having weird problems? Everything was PERFECT on 2.5.2

Ill try providing a logcat, after that im going to try not flashing performance.zip and see if it is any different.

EDIT: seems like it eventually calms down and settles in (maybe because i connected it to the charger). Will try to reproduce and supply log

Logcat attached. The problem happens at every bootup (from a restart or phone off situation). Eventually stops.
[Galaxy S II Original Android Development] redisol:
Experienced the same exact problem on 2.5.2.

How did you manage to fix it?
[Galaxy S II Original Android Development] Anarchist310000:
i was wondering before i tried it if i want to run my own init.d script would i have to remove the battery/ performance script that i flashed along with the kernel since my script would have conflicting values to those in gokhan's scripts

hi all,

have any one tried 2.6 kernel on CheckROM 4, if yes hows battery life?

Following up on my previous post - my phone does have an issue with Market.

SGS2

CM7.1

Seyah kernel 2.5.2 (now updated to 2.6_S99) - *nothing* changed/tweaked except for OndemandX governor.

XXKI3 radio

I can:

- open market

- search market

- browse search results

I cannot

- select one app from search results and open screens of it

As soon as I select an app in Market and I touch either the "More" on description or any of the screenshot pix included, the whole phone freezes as if someone took a picture of it and stuck it on the screen... *Nothing* but long press of the power button helps. Then, reboot. Battery, performance, everything else is beyond great, so I am sad my phone is behaving like this.

Could anyone please suggest what to change/try, so Market works normally? Thanks

i did flash the siyah-battery.zip on check rom v4,but every time i play a game ,about one minute into it ,the game suddenly hangs.

the music is still playing but the video is stuck and slightly vibrating .

when i press the home button and then resume the game from the task manager ,it works fine for some time. then the cycle continues again.

anyone facing similar issues?
[Galaxy S II Original Android Development] droidphile:
Those are the problems with your cpu not able to handle gpu uc/uv and static bus frequency scaling.

Raise clock & voltage of gpu & set dynamic bus frequency scaling.

In /system/etc/init.d folder, open 01siyah script in Script Manager.

Change this line:

echo enabled > /sys/devices/system/cpu/cpu0/cpufreq/busfreq_static

To

echo disabled > /sys/devices/system/cpu/cpu0/cpufreq/busfreq_static

And

Change these lines:

echo "100 267" > /sys/class/misc/gpu_clock_control/gpu_control

echo "60% 30%" > /sys/class/misc/gpu_clock_control/gpu_control

echo "850000 950000" > /sys/class/misc/gpu_voltage_control/gpu_control

To

echo "160 267" > /sys/class/misc/gpu_clock_control/gpu_control

echo "60% 30%" > /sys/class/misc/gpu_clock_control/gpu_control

echo "950000 1000000" > /sys/class/misc/gpu_voltage_control/gpu_control

Try videos and games now.

Battery drain over night:

CM7 ...................... 2%

2.5.2 ..................... 2%

2.6 original .............. 4%

Testing fixed 2.6, always default
[Galaxy S II Original Android Development] gokhanmoral:
Read the second post.battery drain over night doesn't mean anything if you are not in the airplane mode.

And those who experience problem with scripts installed the solution is simple: do not install them.

I am having difficulty of understanding people installing battery script and whine about having lag in games. Also if your phone crash that may be caused by undervolting or overclocking. the default version should run almost as stable as the previous version. If you have problem with battery or performance scripts flash default. Simple and effective.

Yes

Thank you in advance.
[Galaxy S II Original Android Development] gokhanmoral:
Intratech's Frankenstein stock mod is most compatible. You can consider it custom as he replaces the default boot loader and modem.
[Galaxy S II Original Android Development] melorib:
Sorry to disagree, it means a lot, I want to be able to receive emergency calls and SMS during the night, everything else is OFF... :rolleyes:

It is the best way to check if your phone is not doing funny things, for instance the other night it drained 7%, I checked and MAPS was doing its thing, after a market upgrade the previous day, so I froze it and back to 2%... :cool:

[Galaxy S II Original Android Development] Nexu$:
Thank you for this!

I will download and go back to 2.5.2 for now, also reading back maybe a good a idea to return to "Ondemand" instead of the "OndemandX" - just to see if it works well.

XWKI4...?

I have a few questions, but first my apologies if they have been answered before. I read through about 40 pages of posts on this thread, and searched but didn't find the answers and with 1000+ pages of replies...

My phone is from the UK, and is running a rooted stock ROM at the moment (but I'm looking to flash some customs). I've got some experience flashing my HD2, but I'm relatively new to flashing the GS2.

1. Can I flash this kernel when my phone is running the numbers below?

2. If I should upgrade something, how do I know to what? I'm not averse to reading on the subject...but I'm having trouble finding a link to definitive compatibility lists (i.e. which kernel fits to which ROM/radios etc).

3. (Apologies if this is in the wrong forum/thread) Do I have to upgrade sequentially, through the various versions of GB (i.e. 2.3.4->2.3.5->2.3.6) or can I jump from 2.3.4 straight to 2.3.6?

Thanks in advance (thanks button will be clicked)!

[Galaxy S II Original Android Development] Steven6489:
Here you go..
[Galaxy S II Original Android Development] KcDaRookie:
@sean is here.:

1. This Kernel should work on every gingerbread version

2. The ROMs base on certain firmwares which come with a modemversion, if you use a Custom ROM you stay on a firmwareversion (KK5, KI4/8 or whatsoever), but you are free to use any Kernel and Modem you like best. You dont have to upgrade anything particular, just flash a ROM it will include the modem and firmware that will perform well together. You still can flash Siyah kernel afterwards, it is compatible with all known ROMS.

3. You can go straight to the newest version (CyanogenMod uses Android 2.3.7 sources if i remember correctly)

Are you using Voltage Control app? after (SiyahKernel v2.6 + battery script) ?
[Galaxy S II Original Android Development] maslaq:
After changing the values of voltage i've got freeze and bootloop, next i used ultimate cleaning script and now my phone starts so looong. Around one minute every boot. Earlier it was around 10-15 sec.

Whats wrong with phone O.o?
[Galaxy S II Original Android Development] Bushido76:
When I remember correctly the kernel cleaning scripts wipes dalvik cache too. This will increase the duration of your next boot after applying the script.
[Galaxy S II Original Android Development] rauschkugl:
Nothing is wrong with the phone. You just don't know what you're doing.

The long boot after the useless script is nornal because dalvic gets wiped. And freezes are also normal if you just decrease voltage that your phone can't handle.

Help cleaning init.d

Ok, so I'm planning to switch from 2.5.2 to 2.6 + battery.zip. I want to do a clean install of the kernel after removing all remnants of previous versions. The contents of my init.d can be seen in the attachment. Is safe to delete all these files. I use voltage ctrl extreme to OC/UV and I have removed boot settings. I heard the the utimate cleaning script is bogus so is it enough if I do the following steps or is there another way to clean remnants of previous kernels?

- boot to recovery

- wipe cache

- wipe dalvik

- reboot to restore

- flash siyah 2.6

- wipe cache

- wipe dalvik

- reboot phone

- reboot to recovery

- flash battery.zip

- reboot phone
[Galaxy S II Original Android Development] droidphile:
Melorib for you SOD problem, the default deep sleep entering frequency of 800mhz might be the culprit.

Add these two lines in any of your init.d script (or create a new one if you don't use any).

echo "3" > /sys/devices/system/cpu/cpu0/cpufreq/deepsleep_cpulevel

echo "0" > /sys/devices/system/cpu/cpu0/cpufreq/deepsleep_buslevel

This sets deep sleep freq to 1000 mhz which is Samsung stock. Reboot and see if the prob is solved.

Don't think ThunderBolt! kernel will come out anytime soon. I'm looking at SGSII sources and seeing if I can make any changes from SGSI kernels like Talon and Semaphore kernel currently.
[Galaxy S II Original Android Development] xavihernandez:
Ok thank you, then I just have to disable "Set on boot" feature or do a complete uninstall?

You don't need third party app to enable BLN. Go in settings > device settings (below CyanogenMod menu, I have a different language I'm not sure about menu name). Then enable notifications by LED.
[Galaxy S II Original Android Development] stevehkim:
the people having heat issues and phone acting funny is definately an error on user end. i had the same issue with heat and phone acting funny. i installed 2.6 without clearing everything first. make sure you rid of vc settings and setcpu. flash the new kernel twice. wiping dalvik and cache partition before and after the install. once the phone boots up let it sit for a few mins allowing dalvik and cache to rebuild itself. im currently using siyah defaults as it is a perfect comprimise to performance and battery. from there adjust your uv settings to get yourself a little more juice. i unplugged the phone last night with 100% and woke up 7 hours later to find my phone at 98%. 98% of that was deep sleep according to cpuspy. i believe 2.6 is much much better than 2.5.2. you must give it at least a day or more before giving any judgement. if still you are having issues go back to the previous kernel. dont just complain to gokhan after 10 mins of play.

where I can set the values for the hotplug parameters in order to control 2nd core activation?
[Galaxy S II Original Android Development] tolis626:
So,I was playing with my clocks/voltages for the past days,and I want to share some stuff with you guys.I thought 1624MHz was too much for daily usage(Not that I care,but it seems that I put unneeded strain on the phone for minor performance improvements),so I decided to tune it down a lil' bit,mostly for using lower voltages.I was using 1425μV for 1624MHz and I think 45nm chips have a maximum recommended of 1450μV.Being so close for everyday use is rather risky.

I know you don't care,and in fact you shouldn't.But I'd like to say some things for the guys who are new to undervolting/overclocking,so that they have a better understanding of what "Every CPU is unique/different" means.

i)Every CPU has a relative limit.If the limit is reached,it doesn't mean that you can't overclock further,but it needs big voltage increases to overclock further.My phone runs stable at 1504MHz with 1325μV.1536MHz struggles to work at 1350μV,depending on room temperature most of the time.1375μV works for a very small range of frequencies.1576MHz needs 1400μV,and as I approach 1600MHz,I need to increase to 1425μV.

ii)Every CPU has an absolute limit.Once it is reached,it can't overclock further,unless you provide it with enough voltage to fry it.My CPU's absolute limit is 1624MHz at 1425μV.1632MHz and above crash after a short while,even on higher voltages.

iii)Undervolting does NOT affect performance,neither does it decrease your CPU's lifespan.Contrary,it may increase your CPU's lifespan because it generates less heat,and heat dissipation is an issue with the GS2.

iv)Overclocking doesn't necessarily mean your battery will drain substantially faster.It's more a matter of usage pattern.

v)Sometimes,when the phone is unstable no matter how much voltage you give it,it can be a problem with the voltage regulator.It,like the CPU,isn't the same in every phone.Some can't provide enough voltage.

I could be wrong with some things,but these are things my experience has taught me.Someone with knowledge on the subject is free to correct me. :)

Also,some of the definitions I used are my own description of what's going on and aren't officially used. :)

Hope this will help someone.

no auto brightness?

Ok so I flashed 2.6 + battery.zip. I also used the cleaning script but my init.d still has all the files mentioned in my last post. Only now a new siyah one has been added since I flashed the battery.zip. Also now when I open voltage ctrl extreme, I get the warning/error saying kernel has been altered or something of the sort. I get the same warning when I flash a kernel like speedmod that doesn't support OC/UV. Also, battery.zip makes my phone unresponsive to any screen adjustments at the lowest level brightness and 'auto brightness' no longer works. :( Anyone else has this issue?
[Galaxy S II Original Android Development] xavihernandez:
Well I think it's not related to the thread (and to kernels) but since people are kinda active here I'm gonna ask you something: do you have a volume issue in headset. Like when progress bar is at 50% volume does not increase after even progress bar goes to 100%. I think its a known issue. But someone may have a fix. Please share your config if you do not have this issue.

Thanks on advance people.
