hmm..thats strange..but.one thing~i can confirm~in 250hz version~sometime its normal but sometime its have this problem.

200Hz and it's fixed.

KG2 has green also with 250.​
[Galaxy S II Original Android Development] hardcore:
K1-T11 now with HZ=200. Front camera should be fixed.

Also increased charging speed for miscellaneous USB cables. Might be risky for certain chargers.
[Galaxy S II Original Android Development] DoubleYou79:
maybe a dumb question, but what does that mean exactly?
[Galaxy S II Original Android Development] PatoPoroto:
mmmmm "Might be risky for certain chargers"?

so my green bar stay there (in my phone at least)

I use the charger much more than the front camera....
[Galaxy S II Original Android Development] nickporwal:
Awesome kernel..........Nice work hardcore..........Just noticed that CPU now changes frequency stats very quickly. CPU goes 200MHZ to 1200MHZ (for moderately heavy tasks) and then again down in no time. Very good Responsiveness.....keep up the work buddy.
[Galaxy S II Original Android Development] hardcore:
By default the SGS2 charges very slowly when connect to a non-Samsung charger. This should make it charge at the same speed as the AC charger when connected to certain USB chargers (some car chargers or battery packs).
[Galaxy S II Original Android Development] DoubleYou79:
thanks for the quick answer.
[Galaxy S II Original Android Development] geistteufel:
Have you try to upgrade your Camera Firmware from Samsung Apps ?

Search GalaxyS2 ...

And see if the problem still there,
[Galaxy S II Original Android Development] geistteufel:
Is they a way to get it over CWM ? It's really more simple to install it that way, I haven't got my Windows all the time,

Could you make a CWM for T11 ?

I have found the T10 at 300 hz for CWM from post on page 31/32 but why 300 ? it's different from the first page.

Thanks
[Galaxy S II Original Android Development] alucine:
With old version T8 i have lag when my phone is with screen off and turn on.

Anymore with lag ?

My rom is KG1 and with stock kernel is more faster screen off to screen on :confused:

thanks hardcore for your work
[Galaxy S II Original Android Development] russell.nash:
You don't really need Odin to flash it. Just download the tar file to your phone, then extract it with e.g. Root Explorer and flash the included zImage file with the CWM App Option "Flash Kernel" (is included in Litening ROM or the like).
[Galaxy S II Original Android Development] geistteufel:
Okay ! Thanks for the tips
[Galaxy S II Original Android Development] shawn_pro:
Amazing work hardcore, let your magic flowing to us man.

Which reminds me, hardcore seem to have stopped at K2-13. Should be a good time to flash again! :D
[Galaxy S II Original Android Development] interfreak:
Thanks very much guys, still pretty new to the GS2. :-)

Will I see the yellow triangle at boot if I use this kernel?

I'm thinking of flashing my GS2 with the stock JP1 ROM (2.3.5) and then with this kernel...
[Galaxy S II Original Android Development] mach0boi:
Yup. All custom kernels does that :)
[Galaxy S II Original Android Development] byobodybag:
Well, just make sure you know what you're doing. Goodluck! :)
[Galaxy S II Original Android Development] interfreak:
Yup, thanks. :)

I just updated to KJ1 (2.3.5) and my Quadrant scores have jumped to ~4000. The phone is VERY smooth to use.

Dunno if I should install this kernel. Does it make a huge difference?
[Galaxy S II Original Android Development] madroxx:
yes this kernal is made to give u best of both worlds. both performance and battery backup.
[Galaxy S II Original Android Development] bungknees:
It is by far the best kernel available for sgs2. Don't let the other ones fool you with overclocking and undervolting, this kernel performs better with no unstable tweaks at all. Once again great work hardcore.
[Galaxy S II Original Android Development] fenomeno83:
Hardcore, have you plan to introduce smartassv2 governor?
[Galaxy S II Original Android Development] Tiim:
Only if you flash it directly through Odin...You can flash CF Root via Odin first which will give you root and CWM without the triangle, and then flash Speedmod via CWM.
[Galaxy S II Original Android Development] eRPeeX:
No if you use cwm

[Galaxy S II Original Android Development] rajaspidey:
Am going to flash this kernel on my SGSII!! i have following doubts

1. This is not overclocked / Underclocked kernel right?!!

2. Am on 2.3.3 XWKF3 rooted & with CWM so can I use this kernel

3. will this kernel causes any bootloop for my firmware ??

4. Can I flash this via CWM or does odin required??

5. Does this kernel change anything from stock except speed & battery efficiency??

& also it would be better if someone give me step by step guide ;-)
[Galaxy S II Original Android Development] rajaspidey:
don't go for Underclocked or overclocked kernel!! overclocking ll just give us big numbers but SGSII is already faster t-an needed :-)
[Galaxy S II Original Android Development] sahidmiah:
If u use CheckROM v2 xxk14 with this kernel u will get 4670 quadrant. Because it has been cleaned up by the dev. With stock rom its too buggy.
[Galaxy S II Original Android Development] rajaspidey:
flashed speedmod!! got 4200 with all process running & all power saving options on!! ll soon post pics!!
[Galaxy S II Original Android Development] gasmias:
with stock ki4 work fine, better than stock kernel, benchmark score is around 4500..
[Galaxy S II Original Android Development] planetf1:
Hi,

I've been loving speedmod here -- exactly what I was looking for. I'm using 2-13 alongside KJ1 on a SGS2.

But just today I had some strange behaviour that I can't explain

Battery is plunging at over 10% per hour even when mostly idle

Handset is not properly going into deep sleep

Partial wakelocks (according to BBS) remain low (in 3:06 highest is google+ at 4 mins -- partly from my post below)

Cpu load (from BBS) is low from normal apps, though "suspend" shows at 17 mins of 3:06 and events/0 also shows at 17mins

I took some pictures and made a post earlier - I didn't want to overload the post here with shots though I can report on request. for now they're here https://plus.google.com/104422026240308775849/posts/U3dpmuZe3iB

* Could this be a modem issue? (am using KI3) - what else wouldn't really show?

* Is 17 minutes on events/0 a sign of something not right?

Most of the time with the new kernel the regular load, with plenty of push services active has been around 2% ph, and battery life has been superb - yesterday I was at 80% after around 12 hours!

I'm tempted to reboot, but at the sametime think I should leave as is for debugging. For now perhaps I'll give it a top up charge!

Ideas?

Specifically looking at increasing the battery life by tweaking the gpu and cpu power levels.

SO true mate... Tried out nearly all kernels and I always came back to speedmod!

[Galaxy S II Original Android Development] Radikaal:
hehe, agreed, 4d is no problem to get if you use the screen for >1-2hours or less :) havent been on any ROM or kernel for me atleast (only tried once thought and got 4d+ just to test) but i know how much it drains in idle and its so low its easy to get that kind of amounts :)

2d with 6h screentime is my record and i got it with k2-13. Not to mention not a single problem, high benchmarks and no lag anywhere in the phone.:D
[Galaxy S II Original Android Development] FrenchSparda:
2 days...6 hours screen...but what kind of settings ? Lots of browsing ? Wifi enabled ? 2g ? Wich browser ? Useless facebook apps ?
[Galaxy S II Original Android Development] Radikaal:
Screen brightness on about 1cm from the bottom (little brighter then autobrightness), 3g on all the time except over a 7h period when i just turned data off. No wifi. Standard browser, used maybe 30min only because i use the xda app to check this site which im mostly on and a news app to read news. About 1 hour in a wallpaper app downloading wallpapers, 2-3hours on imo (facebook&msn chat). Weather sync on all the time on a 3h period. Was my only app wakelock in batterystats and it was on 10min in total or something. Always had 96-98% deepsleep when i turned off the screen. And i dont have facebook app installed, i use the facebook widget in launcherpro/go launcher instead to check updates and imo to chat, like it alot more then the ****ty facebook app. Always do a facebook update in the widget once every 1-3hour or so on awake time.

Downloaded stuff from kitchen and rebooted 3-4times. Played no games. Other then that mainly lots of texting and setting up different homescreens in launcherpro/go launcher.
[Galaxy S II Original Android Development] KennyLegend:
That's pretty much what I got on ki8 and speedmod.
[Galaxy S II Original Android Development] interfreak:
OK, bit the bullet and installed this kernel...

Quadrant is now reporting scores of 4664 on the stock KJ1 ROM!!! :O

I've purchased the USB jig to get rid of the yellow triangle. :)
[Galaxy S II Original Android Development] Brotuck:
Easy way to get rid of the triangle:

- Copy latest speedmod zImage to sdcard

- Make sure you have CWM manager installed

- Reboot to downloadmode and flash with odin STOCK kernel

- Once booted open CWM manager and select flash kernel. Select the zImage file and you are done !
[Galaxy S II Original Android Development] interfreak:
Awesome, thanks for that!
[Galaxy S II Original Android Development] planetf1:
Following on from

a) My post about wonderful battery life

b) My sudden transition to awful battery life (no deep sleep)

I've now

* Backed off/removed all apps installed during this period

* checked things like voice search and other settings

* experienced 2 kernel hangs (screen will unlock, but desktop is frozen -- maybe a touchwiz hang)

As such I'm now reflashing the base rom, and then the kernel (both at the same version) in case I messed up anything as root (I did run some root apps but nothing dangerous, and only changed a single file - wpa_supplicant for adhoc networking)

if that fails I can always do a full reset :-( [I use titanium backup so am ok as long as that doesn't also restore the fault!]
[Galaxy S II Original Android Development] interfreak:
I've done as you say, but when I open CWM manager I can't see an option to 'flash kernel'?
[Galaxy S II Original Android Development] Brotuck:
I use CWM manager 2.0

This comes with the installation of cfroot kernels.

Maybe you are using a older version ?
[Galaxy S II Original Android Development] shawnaye:

[Galaxy S II Original Android Development] interfreak:
Sorry I was blind and didn't see it lol! :)

[Galaxy S II Original Android Development] Radikaal:
Just tried (god forbid) another kernel, the siyah 2.1 final since its so hyped and the release notes looked abit too good to be true, after being on speedmod since the K2 series released it opened my eyes even more how awesome speedmod is.

Even thought i got a record benchmark in smartbench 2011 with siyah at 1200MHz it was very noticable it had a little bit of more delay in everything, scrolling between homescreens even in launcherpro which i think is fastest in this regard had tiny bits of lag from times to times which speedmod never ever has. Scrolling in menus was also noticable worse.

Did a cache/dalvik wipe and reflashed kernel to see if it had to do anything with that, same results, flashed back speedmod and on first boot the phone's speed is back to perfection again :D

I think siyah's release notes cause alot of placebo effect of many people so they think they have the fastest kernel out there :D

If any kernel should have "one kernel to rule them all" in its name its this.:)
[Galaxy S II Original Android Development] loveleeyoungae:
Went back to k2-12. The k2-13 seems to drain faster, even though I got 97% deepsleep overnight.

PS : You can see that for the 15 - 20 first %, I had a bug so this is not in the stats...
[Galaxy S II Original Android Development] darkmessiah:
please advice..

i jus moved from the new siyah darkknight kernel to this speedmod kernel jus now.

I really feel the performance improvement on this kernel with checkrom 2.0

do I need to install setcpu now?

[Galaxy S II Original Android Development] bungknees:
No need to install setcpu. just run the kernel and see the great results.

Got about 40hours battery with 10h wifi on, 14hours 3G, 3,5h display on.

To reset this one you do need a compatible bootloader and jig.

SpeedMod on KI4 2.3.4?

I'm running stock rom 2.3.4 XWKI4. I've rooted with CF-Root. I've read that CF-root needs to be the same kernel (2.3.4 in my case) as the current kernel. Is this also the case for SpeedMod or can I just flash the latest one?

I know others asked this a few pages back, but couldn't find the answer.
[Galaxy S II Original Android Development] justsimple1:
Which font are u using? Pls give apk...
[Galaxy S II Original Android Development] Tyrol:
No factory reset necessary. Just flash (zip via CWM Recovery, tar via Odin). You may want to do a Nandroid backup beforehand, just in case.

sorry pal. only option for me is to go thru Odin. Also, trust i cannot do a nandroid backup since i haven't rooted or installed cwm recovery!

however, i was concerned if i need to wipe prior / after flashing this kernel.

Following on from a previous post I've now done a complete full reset, set csc to XEU, reinstalled KJ1, reinstalled 2-13 & restored apps from Titanium backup.

Even with relatively few things running, and just the usual push services active I'm continuing to see drain approaching an average of 10% ph with light use

In 3.5 hours my screen was on 25 mins (light use).

Battery has dropped to 75%

Wakelocks (user) are very low

I had 1:50 of deep sleep -- so good to see some

I still had 1:03 of 200 Mhz (not charging) and 70 mins of other speeds despite only 5-10 mins use here and there

latitude is not enabled, nor is GPS

I've uninstalled/frozen as much as I can

"system tuner" isn't showing any process runaways - it does peak to 20-40% every 10s or so -- wondering if that's the cause and/or if there's a better tool to use

Still confused as to how I broke it/how to debug

The only "root" apps I have are ES file explorer, astro, titanium backup
[Galaxy S II Original Android Development] dzontra11:
Amazing battery...medium user.

Still 44%.
[Galaxy S II Original Android Development] Tyrol:
Ah, I see. Nope you don't have to wipe. It won't erase or change any data or settings. Just the kernel.

[Galaxy S II Original Android Development] :
Skype installed?

Don't restore apps using Titanium at least until you know it is not one of the apps causing it.
[Galaxy S II Original Android Development] :
I saw your post in the Siyah thread and thought, wow, an honest and sincere compare/contrast, then I read this here and realized it was likely just trolling; am I wrong?

I've used both, extensively, I prefer some things about Siyah, and some things about Speedmod, they're both good kernels but for markedly different reasons; as you noted even the "selling" of the kernels are on different ends of the spectrum.

Entering the "the kernel I flashed on my phone is better than the kernel you flashed on your phone" arena does nothing for either.

My take on it is that Siyah is great if you want to tweak and modify settings, have power hungry features enabled, or not, run the same kernel on your AOSP ROM as your Sami ROM, etc... Speedmod does exactly what it says, and does it well, I admire Hardcore for sticking by his guns and not adding features that he thinks go against the mandate that he has for the kernel.
[Galaxy S II Original Android Development] punshkin:
How much is the battery improvement? And is there a version without the screen tweaks? (I like it over saturated as it is :O
[Galaxy S II Original Android Development] planetf1:
No -- no skype. Discarded that a long time ago due to power hit.

Fair point about the backup - if nothing else if demonstrates titanium does what it says on the tin ;-)

I wish I could see something in wakelocks/cpu etc but can't right now. I have some more things to test/check/uninstall - in particular anything which leaves any processes running. The ICS data traffic monitor would be nice. I also need to double check at home -- since that's where I noticed the superlative battery performance, but is also where I have superfast wifi & a 3G femtocell...
[Galaxy S II Original Android Development] alexkno:
But you also calibrated your battery?

If then besides the user apps wakelock there are other things that may drain:

network - ensure to only use fast dormancy in case your provider supports it (*#*#9900#*#*). Otherwise your modem will wait for the order to sleep, but it never arrives.

modem: maybe the modem you use is not good in your area, check with another one

check system processes that kept phone awake:

via terminal: cat /proc/wakelocks > /sdcard/wakelocks.csv

and check the entries with highest 'sleep_time' (you can also import it to excel and then order by this column)

(please check: http://xdaforums.com/showthread.php?t=1290020 )

For me for example the old facebook app kept phone in wakelock very long and then it was friendcaster that used C2DM notifications that caused the wakelock. Having switched off notifications for both (I receive an email anyway) I have about 5-10 hours more with same display and network usage
[Galaxy S II Original Android Development] bungknees:
i would suspect it is the push services that are keeping it from deep sleep all the time. Perhaps try instead of push, set up your accounts to manual update,or every hour or so then see if your deep sleep lasts longer. Also I had skype installed and even though i never used it once it was keeping the phone from deep sleep for long periods, uninstalled skype and have never had a problem since.
[Galaxy S II Original Android Development] henriquesb:
CPU Spy and BetterBatteryStats are really useful. Noticed a huge drain yesterday and it was caused by Facebook Chat. Make sure to go into Facebook app, select Chat, then Go Offline, and Deep Sleep will be back :)
