I too can play some good length movies without heating up issues, but this is happening only when playing some music in background(either headset or speaker) and using any other app (like opera,xda app) with mild usage, i can feel the warm screen within 2 to 3 minutes. Strange for me too!!
[Galaxy S II Original Android Development] :
Because it's still the most stable one. With your knowledge you can easily install any recovery you want/need.
[Galaxy S II Original Android Development] mach0boi:
To those who suggessted a full wipe before flashing 1.8, unluckily it still didn't work. I am not new to flashing kernels so I really know I'm doing it right. Tried downloading several times, flashed it a thru cwm and odin but it will just get stuck at the boot logo, not the samsung boot logo with the yellow triangle. The boot animation will play for a while then the animation will stop and the phone will freeze. Tried to wait hoping it will boot. After a while the softkeys lighted up, but the phone restarted again. There's something in v1.8 that made it not to work on others. Flashing RC3 back and other previous versions fixed the problem.
[Galaxy S II Original Android Development] Silverbolt:
I also found 1.8rc4 better. I use Dolphin browser and get white pixilated lines in the first 2 tabs.

I used to get this with Hardcores kernels.

I have noticed my phone stays warm too, even in my pocket when not in use.

Do you still have 1.8rc4 available to download?

Battery lasted longer for me using 1.8rc4.
[Galaxy S II Original Android Development] twosix:
On 1.8 and using "ondemand" gives the best results. Everything else is stock.
[Galaxy S II Original Android Development] jdmcivic:
What rom are u on? Do u happen to have flashed ki3/ki8 with new bootloader?
[Galaxy S II Original Android Development] Mayday_XL:
My S2 shows CM 4.0.0.2 ?! :confused:
[Galaxy S II Original Android Development] gokhanmoral:
v1.8 doesn't work and 1.8rc3 does?
[Galaxy S II Original Android Development] :
that's correct.
[Galaxy S II Original Android Development] gokhanmoral:
there is no difference between rc4 and release except for the drivers.

I am using drivers from update2 sources in release. Samsung will release new sources for SGS2 soon and I am waiting for them.
[Galaxy S II Original Android Development] Silverbolt:
I still think your kernels are the best, so for now I am back to 1.7.8.

I only wish I had the knowledge to do the great work you do.

So, thank you
[Galaxy S II Original Android Development] mach0boi:
Yup that's right. Rc3 was the latest version I downloaded and it's the one I'm using right now.. I'm not the only one having an issue like this read the previous post and others are experiencing such issue.
[Galaxy S II Original Android Development] :
my guess, and only a guess because ATT sources drivers are newer they worked with new bootloader, while update2 are older and don't want to. I may be totally wrong of course.

It's a wild guess, don't flame me :)
[Galaxy S II Original Android Development] mach0boi:
Nope, haven't flashed a ROM with a bootloader in it. Using androidmeda.
[Galaxy S II Original Android Development] frankcilo:
With some kernel (and this kernel) when I disable fast dormancy with *#9900#, after few minutes or few hours, it return to enable.

Can you fix this?
[Galaxy S II Original Android Development] :
it happenes with almost every kernel, do it second or third time and it will eventually stick as in my case.. also, I just tested for some time and with latest radios there is really no impact on battery life with fast dormancy enabled or disabled so you might consider leaving it enabled.

That's just my opinion.
[Galaxy S II Original Android Development] gokhanmoral:
thank you. this info is what I needed most to solve the problem.
[Galaxy S II Original Android Development] Galaxy_Fan:
Stutterfree drawing / Solution

ondemandx is better cause it uses the screen off option

For me I found my best:

I don't play games so lagfree is absolutely stutterfree for phone usage and vr for the scheduler.

Tested with SPB Shell3D and some other apps.
[Galaxy S II Original Android Development] jmblazquezh:
But Recovery 4.0.1.5 worked perfectly.

Regards.
[Galaxy S II Original Android Development] Peeyar:
Can anyone pls tell me what i/o scheduler is the best. i am totally confused because i dont know what to use. right now im using deadline some are using sio which i which thanx.
[Galaxy S II Original Android Development] gokhanmoral:
did you experience any problem with 4.0.0.2?

I just wanted to use "the most" stable version with back button support in the release.

if you have a problem with 4.0.0.2 please tell.

or is it just "newer is always better" issue?

cf-root is still using it in v4.3 and I never heard about anybody having any problem with that version ever.
[Galaxy S II Original Android Development] :
So does 4.0.0.2. what's your point?
[Galaxy S II Original Android Development] bandit79:
4.0.0.2 works fine, not any issue or problem
[Galaxy S II Original Android Development] Galaxy_Fan:
never happened on my phone
[Galaxy S II Original Android Development] :
So I made another test this morning:

1. full wipe of everything

2. install stock ki8 kernel via Odin (reboot x2)

3. install stock ki8 rom from Intratech thread via Odin (be sure new bootloaders are removed or use frankenstein version - thanks gokhan) (reboot x2)

4. install cfroot ki8 kernel via Odin (reboot x2)

5. install stock ki8 kernel via Odin (to get rid of yellow exclamation mark, reboot x2)

6. install cfroot ki8 via CWM app that was on my phone because I rooted with cfkernel (reboot x2)

7. install Siyah 1.8 the version I just downloaded this morning (I guess old compiler) via CWM app (reboot x2)

Not a single problem. NONE. Works like a charm. Your SGSII cannot be that different, unless you flashed ki3 or ki8 that included new bootloaders and there's solution for this, go to Intratech thread and find it.

Let's move on to 1.8.1 now :D
[Galaxy S II Original Android Development] Galaxy_Fan:
look my post above.

vr is very good if it runs on your device. btw. deadline (tweaked like here) is good too.

There is not so much difference that you can feel, just minor things.

governors have more impact
[Galaxy S II Original Android Development] gokhanmoral:
I just want to add that you have to download "frankenstein" version of ki8.

other one has the original boot loader and may have problems
[Galaxy S II Original Android Development] bandit79:
never happend. it's still disabled since v1.7x
[Galaxy S II Original Android Development] dexgore:
I cant use your 1.6 cwm version. cwm and cwr give me abad file error. I try redownloading it 3 times
[Galaxy S II Original Android Development] dkflint723:
Is there a v1.6sp1 for the SC-02C? I keep getting random reboots with 1.6.
[Galaxy S II Original Android Development] spaxx24:
Two times when I try to wake the phone from deep sleep it has not responded, I have had to take out the battery and restart, and when it starts i lose like 10-20% battery, even if it is just "dead" for liek 10 minutes maybe.

Is this some problem with my undervolting or? It is stable otherwise, never dies when screen is on etc.

Im using cognition v1.51 with 1.6 of your Kernel.
[Galaxy S II Original Android Development] gokhanmoral:
most probably... undervolting or 100MHz clock maybe.. or the governor.. or any combination of those which makes the settings different from the stock.

it's not possible to say it for certain. every device is unique in a manner and stock settings are chosen to cover them all. try to change one thing at a time and see if it is resolved.
[Galaxy S II Original Android Development] spaxx24:
I had it set to 200MHz-800MHz, gonna try 100-800MHz then

edit: And then it died instantly haha, so I guess the undervolting on 100MHz is low.
[Galaxy S II Original Android Development] pesho00:
Had the same problem (10% in 10 minutes and no response, battery removed;)). It was caused im my case from 100MHz setting, solution was to rise voltage on 200MHz +25mV (to 875mV, from 850) and now everything is OK.

i have 800-100 MHz on 975,875,875 and 850 mV (respective for 800,500,200 and 100)
[Galaxy S II Original Android Development] ram3n:
Hi my friend,

set to 200MHz-800MHz with :

200 Mhz - 800 mV

500 - 825

800 - 950

Very stable and smooth as for ninphetamine's =)

But 100 mHZ freezes my phone...

Cheers, waiting for 1.7 update !!

---------- Post added at 10:59 AM ---------- Previous post was at 10:49 AM ----------

BTW, how to use GPU clock and voltage control interface in order to undervolting/UC ??

thanks :)
[Galaxy S II Original Android Development] pappschlumpf:
Hi,

the feature list of your kernel looks very nice! What do you think, is it possible to add tegrak overclock ultimate support, too? As I underrstand only support for loading his kernel module is needed.
[Galaxy S II Original Android Development] gokhanmoral:
why not... I will look into it after releasing a beta for v1.7
[Galaxy S II Original Android Development] pappschlumpf:
Thx, I'll give it a try if Tegrak support is included.

With the stock kernel and Tegraks own kernel it's working. If I remember correctly in most custom kernels something is changed in the way loading modules.
[Galaxy S II Original Android Development] mehmetenis:
Dear Gökhan:

1.6 SP1 Not stable.

In phone call after no turn back.I'm reset phone.

Turn back 1.6
[Galaxy S II Original Android Development] gokhanmoral:
can you please try v1.7beta1?
[Galaxy S II Original Android Development] :
can you please give quick info on new governors in 1.7b1
[Galaxy S II Original Android Development] gokhanmoral:
there are only 2 new governors in beta1 for now.

lagfree and savagedzen

first one is obvious :)

savagedzen is based on interactive governor with screen-off freq support. just like interactivex.
[Galaxy S II Original Android Development] gokhanmoral:
I think I have solved wakeup from sleep problem.

everybody should try to lower their undervolt settings, especially for 100MHz.

a friend of mine had wakeup problem all the time with 1.6 and he is now telling me it never happens with 1.7 with 100MHz@800mV.
[Galaxy S II Original Android Development] :
So it has integrated screen-off 'profile' like smartass?
[Galaxy S II Original Android Development] gokhanmoral:
exactly. not tuned yet but it seems to be good and less laggy.

but the main thing you have to test is waking up from sleep :)

everybody please use 100MHz and report back.. I will not make new improvements until I solve that for everyone..
[Galaxy S II Original Android Development] :
why use 100MHz? for even more battery savings? just curious?
[Galaxy S II Original Android Development] gokhanmoral:
yes, exactly. my primary goal is to have more battery life.
[Galaxy S II Original Android Development] :
Okey, SavagedZen sucks ATM, so I am using smartassv2 100MHz just slightly undervolted as I like it (I can undervolt way more, but I have a theory that it drains more battery). I will report on waking up from sleep.

thanks.
[Galaxy S II Original Android Development] :
correct. sorry I assumed people would know that :)

[Galaxy S II Original Android Development] crypticc:
You'd rather have a menu button than a back button that actually works and a stable flash??? This can't be for real
[Galaxy S II Original Android Development] demonious:
really misleading (i mean the post) cos i thought author said below this point all firmware will come with old bootloaders which include ''the other'' official ki8 firmware
[Galaxy S II Original Android Development] crazykamui:
bootani not working..?

Hmm, sorry i'm little English

Are you init.d script GPU UV?

I'm GPUUV script 1.8a and 1.8b kernel is no probs

but 1.8kernel is not working bootanimation..

init.d - GPUUV script deleting - working bootani...

GPUUV script voltage change - working bootani..

----------------------------------------------------------------------

gokhanmoral!!!! you are Hiro.. big thanks!!! kernel is Best...^^
[Galaxy S II Original Android Development] Kaboosey:
Currently using 1.8 and it's working fine and smooth for me coupled with CriskeloROM. :)

Thanks for this great kernel, absolutely amazing I must say! Can't wait for the next update after Samsung released their sources :)

Keep up the great work and again, thank you!
[Galaxy S II Original Android Development] :
well the main point is to be sure you are using firmware that doesn't touch bootloaders.
[Galaxy S II Original Android Development] gokhanmoral:
I agree. when I read his post I thought all versions have old boot loader.

then I realized that he meant the frankenstein versions and there is also a frankenstein version for new builds.
[Galaxy S II Original Android Development] demonious:
Thanks for the insight, will be extra careful when downloading official firmwares from now on.
[Galaxy S II Original Android Development] pachinkosan:
man, that's not helpin

good for you that 1.8 works at u'r phone
[Galaxy S II Original Android Development] :
Are we still discussing recovery? Really? 4.0.0.2 is used in cfroot, ninphe and siyah kernel and it is most stable. If you want any other one, do it yourself, pretty easy.. if you think the other is better than you should also know how to do it.

siyah 1.8 works beautifully as it is, even if you just install it and not use any other setup. 4.0.0.2 works great and is stable and does everything as needed.

let's move on, please.. if recovery > kernel, there are other kernels with 'newer' recovery. if it makes you happy, move on. wow, 5.0.2.3/6 is blue. that's nice..

well then you are doing something wrong. sorry. reflash stock kh3 from Intratech thread and flash siyah, IF THAT DOESN't work give up on this kernel.
[Galaxy S II Original Android Development] JB-007:
not able to launch quadrant

Does somebody has the issue? I got freeze durant 3d scene ....
[Galaxy S II Original Android Development] jdmcivic:
check if u have any gpu undervolting done.

in this release version. the 900mV limit has been removed.

for me, @ 267mhz i cant get anything below 900mV without crashing. bahh
[Galaxy S II Original Android Development] Peeyar:
Regarding governors im using smartassv2. Can you differentiate ondemandx and smartassv2 thnx.
[Galaxy S II Original Android Development] :
ondemandx is smoother and uses (probably) more batter, smartassv2 is less smooth and uses (probably) less battery.
[Galaxy S II Original Android Development] ram3n:
guys, I have a very weird issue with 1.8 kernel :

Every night when i turn off my phone (with 55% battery left for example), in the morning after turning on, battery drops to 45%, so I lost about 10% over the night whereas my phone is turned off !!!!!

What the hell ?? It happened before with others 1.7.x kernel ....
[Galaxy S II Original Android Development] Galaxy_Fan:
right :).

IMO lagfree runs minimal smoother than onemandx. Both are my personal favorite
[Galaxy S II Original Android Development] bandit79:
lagfree drains my battery much more than smartassV2 and ondemandX. for battery smartassV2 - sio was the best, ondemandX - deadline/ vr for performance, but less battery
[Galaxy S II Original Android Development] mach0boi:
WOW! This indeed worked! :D

For those of you who had an issue like mine, please DELETE your GPUvoltage script and it will boot fine. Thank you again ;)
[Galaxy S II Original Android Development] :
ondemandx is mys personal favorite at the moment with deadline/vr, lag free was smooth for me before, but lately there are lags for whatever reason, will have to play more. I like the concept 500-1000/800 on screen, 100-200 off screen.. I think too many cpu-steps kills the smoothness, again don't flame me like for UV, I just state my opinion :)

edit: I hope we can now moan and complain about governors and smoothness and batterylife improvments, yesterday and today up to now were too many post with people thatdidn't want to read so they run into problems. That's OKey, just let start to move on.
[Galaxy S II Original Android Development] rodries:
Be carefully with GPU undervolt mods, maybe you have undervolted GPU
[Galaxy S II Original Android Development] gokhanmoral:
now you see why I did not remove that 900mV lower limit in release candidates :)
[Galaxy S II Original Android Development] mach0boi:
Yeah but going below 900mv on 1.7.8 is fine. I can live without GPU UV anyway. Thanks :)
[Galaxy S II Original Android Development] Jeks0234:

[Galaxy S II Original Android Development] jdmcivic:
lol. did u even read his post? it was just discovered recently. whatever values u set below 900 in your gpuuv will revert back to original values.

sad to say, its just a placebo effect

and now with the release version u gotta find your sweet spot
[Galaxy S II Original Android Development] mach0boi:
LOL. Did u read my post? It was working on 1.7.8, I wasnt talking about v1.8/alpha/RC.:rolleyes:
[Galaxy S II Original Android Development] :
flash stock kh3 from intratech thread and then try.
[Galaxy S II Original Android Development] jdmcivic:
if u were following the posts here. the 900mV limit was discovered by andrelinux and that was during the 1.8rc-betas. sad to say the first stable release was before that
[Galaxy S II Original Android Development] mach0boi:
I solved mine by deleting GPU UV script. If he has it, then just delete it :)
[Galaxy S II Original Android Development] AndroidGX:
When I'am at idle/deep sleep, with smartassV2, the sleep profile included seems draining much more than ondemand (lost 4% in 2 hours this night while sleep mode, so it's far away than my good old ondemand with SetCPU profile where I reached 2% in 6 hours). When you look at the behavior of the smartassV2 with Voltage Control, "General" tab, you can see that the gov balance between 200 and 500 Mhz when doing absolutely nothing, even thought I set the 100 Mhz profile too, it use it very very rarely. For ondemand gov, it's the contrary, idle is much more respected, it comes directly and stays at 100 Mhz for a long time. I guess it explains how the CPU consum more battery in idle state with smartassV2. The good point of smartassV2 is when really using the device, it's saving a bit more battery than ondemand, clearly.
[Galaxy S II Original Android Development] Jeks0234:
where it is located?:o
[Galaxy S II Original Android Development] mach0boi:
I didnt get you. What I'm trying to say is GPU uv script works fine on v1.7.8. So maybe it's also possible to get it to work on latest 1.8 version. I'm aware of the 900mv limit.
[Galaxy S II Original Android Development] jmblazquezh:
I've never had problems with flash anything from the recovery 4.0.1.5, and I've flashed many things, roms, battery mods, bootanimations ...

I doubt you have it because you don't know where it is located. Just try and check if it's there :)
[Galaxy S II Original Android Development] Vulpix:
Another random reboot... :( I didn't do any OC or UV, is the GPU UV thing a default thing in the kernel? :(
[Galaxy S II Original Android Development] newHere:):
i installed today the final version of 1.8 and so far so good :)

the device is cooler than with RC2 and no freezes so far (i had 3 freezes with RC2)

i do not use any OC or UC ...

thanks for your great work ;)
[Galaxy S II Original Android Development] :
delete everything from your init.d, disable all cpu apps like setcpu or no-frills or voltage control or o/c daemon.. reboot.. see if it still happenes
[Galaxy S II Original Android Development] jdmcivic:
on 1.7.8 stable release. yes it states that min gpuUV set at 600mv but actually it isnt. its locked down to 900mv. this was only recently discovered in the sources by andrelinux during beta 1.8.

therefore the gpu UV below 900on 1.7.8 doesnt work as the lockdown was only discovered after.

on 1.8 it is already working. min value is now set to 800. so if u set anything below 800, it will not crash since it is not supported, stock values are then applied but settings will show that u have UV. lets say 100@600mv
[Galaxy S II Original Android Development] Vulpix:
That's the problem, I'm not using ANY of those. I see no init.d in my system/etc folder, so I'm kinda clueless what I can do now. :( There was no reboot issue in 1.8rc2, should I flash via Odin or something instead of CWM? :(
[Galaxy S II Original Android Development] mach0boi:
Thanks for clearing that up. I thought it was working fine. My only basis was sys/devices/misc/gpu voltage control. The values there was correct though :)
[Galaxy S II Original Android Development] Molitro:
C'mon man... enough with the CWM.

If you like other version better, use it yourself.

As far as I'm concerned, most stable + back button >> anything else.
[Galaxy S II Original Android Development] Vulpix:
Apologies, but I have no idea what you are typing there. :( Where can I locate the things that I need to do this dump?
[Galaxy S II Original Android Development] bandit79:
With the OC Dameon - Dameon there's no possibility to set ondemandX @ Wake min/max or screen off min/max. It's still on Bypass. And No-Frills there's also no setting for screen off. So which app u're using? I would take u're settings, but i can't because of this.
[Galaxy S II Original Android Development] jdmcivic:
man hold on while i turn on my laptop..
[Galaxy S II Original Android Development] psychoid:
Had this problem before, edited the gpuv script and good to go :]
