I just flashed the last speedmod over my siyah 2.3 kernel and now my CWM is working but its seem that speedmod using an older version of it so how I can fix it ? since I cannot remove this app from the phone exept in titanium backup

if I flash this kernel again after removed the newer version of cwm will it work ?

Can anyone pls tell me whT the second item in the attached pic is. It says backup android system.

Thanks...

Very good battery savings !

What battery is your phone running on?

And what is the wifi, awake and deep sleep time (or percentage)?

I also wanted to test the "older" SpeedMod kernels too, but as I am using CWM5 backups, I do not want to "downgrade" to an older CWM version.

im usingk2-18 test 12 since this morning and I have cwm 5 and its seem to work but at the start of cwm I still get the cf-root 5.0 need message

Guess it's the google backup service (to sync your apps and configs to/from google servers).

Disable if you don't need that.

Hi there,

I do not know which firmware to update too? Besides that, I do not know which one is for my country (in Singapore).

If I update the firmware, do I need to wipe the phone as well?

Thanks in advance.

[Galaxy S II Original Android Development] CamoGeko:
Depends, I would say yes it is a good idea to wipe since you are going from 2.3.3 to 2.3.5. Even 2.3.6 is out already. ;)

I would still strongly advise you to go for it and update, your phone will become a lot more efficient.

Results for SpeedMod / stock kernels

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 SpeedMod kernels in black, I was running on Frankenstein XWKJ3 ROM.

For SpeedMod kernel in red marked with (*), I was running on Frankenstein XWKK5 ROM.

Always using the Samsung's standard / stock 1650mAh battery.

Here are my current results:

Benchmarks

Battery stats

(*) running on XWKK5 Frankenstein ROM

My personal and subjective resume is that the latest XWKK stock ROMs and kernels became better in browser performance and battery life.

But SpeedMod kernels are still a way faster and a little bit smoother, without being worse in battery savings.

On my phone, I prefer running a SpeedMod kernel on the XWKK5 ROM as this combination offers to me the best balance between performance (speed and smoothness) and battery life.

But everyone will have to find his "the kernel/Rom sweetspot" (quote of interfreak).
[Galaxy S II Original Android Development] sageman70:
What ROM are you using? I am using androidmeda 3.0 and the best I got with k18-t12 is 30hours.
[Galaxy S II Original Android Development] interfreak:
Thanks so much for the effort you put into testing It_ler!!

Could you perhaps test K2-18(10) with the XWKK5 ROM and add that to the list?

I have a feeling that combo will come out on top, seeing how test 10 was awesome with XWKJ3...
[Galaxy S II Original Android Development] kel1ng:
Hi just to check with u whether u have any problems with the samsung s2 original boot animation when u flash speedmod kernel over xwkk5 rom? Coz mine is broken after I flush speedmod over xwkk5. It was only after I flash speedmod over xwkk5 that the original boot animation got broken......can see the forming up of the S but before the S is form, the screen turns blank but my device does boot up normally after the blank screen.....I tried reflashing xwkk5 and the boot animation was alright. But once I flash speedmod, the boot animation got broken again. Wondering is it something I did wrong. Many, many thanks in advance.
[Galaxy S II Original Android Development] planetf1:
Just had k18-test12 near-hang again. Ground to a halt, clock minutes slow, UI unresponsive.

This was on KK5 so it's possible it's a rom flaw, but I've now had it both days I was running speedmod, and not the day I ran cf-root/stock ...

Now need to decide previous speedmod kernels vs stock (or siyah) to check stability.

---------- Post added at 11:34 PM ---------- Previous post was at 11:22 PM ----------

Decided to go back to k18-test10

since

* I like speedmod (speed, power, auto brightness reduction)

* making a minimal change may help isolate a potential flaw

* the test10 seems to score well on performance, and battery life - + I'm thinking the preempt_voluntary could be the way to go in future

* The main changes to 12 are the preempt-voluntary, which changing hasn't been an issue before & the CFQ scheduler/hrtimer -- the latter I'm thinking could be a factor

So far a crash has occurred within 24 hours so will run this test through the weekend I think
[Galaxy S II Original Android Development] fenomeno83:
So, i think that the "battle" is between test 10 and test 12...maybe is better make a poll to choose what version will be final

I got the exact same issue...did you try cwm 2.0 ? Did it resolve the issue? It seems funny that we have to go backwards on the cwm versions for this to work.

This is the file I installed . I rebooted into recovery mode and installed the zip from the internal SD card.. speedmod-kernel-s2-k2-18-test12-CWM.zip

I thought this kernal would change my cwm to CWM v4.0.1.5 according to the info on Page1 of this thread , but it is still v3. Am I missing something?

Anyone ?
[Galaxy S II Original Android Development] adl:
Thanx for the link,will try test 10 as well,test 12 was very good but test 10 sounds promissing too. :)

Battery wise which should be better: test 10 or test 12?
[Galaxy S II Original Android Development] globalgpj:
I think the consensus opinion from most users is that Test 12 is giving amazing battery results.

I am personally getting fantastic battery results with T12...so I am very very happy. :)

Hope this helps.
[Galaxy S II Original Android Development] planetf1:
Re test 12. For me battery was good but the hangs rule it out completely.there seem a few in this thread, not seen with other builds.though more testing time needed in case there's another cause.
[Galaxy S II Original Android Development] Lovehepburn:

No problem with boot animation.

But I had to flash SpeedMod kernel twice onto my phone running on XWKK5.

After the first flashing, the wifi connectivity was "broken" (I could not get connected to my home WLAN).

I restored my nandroid backup of XWKK5 (with CF-Root kernel), and flashed the SpeedMod kernel again.

After the second flashing, everything was fine.

---------- Post added at 09:32 AM ---------- Previous post was at 09:16 AM ----------

That's exactly what I am doing now.

My "kernel/Rom sweetspot" was SpeedMod K2-18-test10 kernel on XWKJ3 ROM - that was the best balanced combination on my phone.

So, I flashed Test10 onto my XWKK5 ROM.

But ... my first results are a little bit disappointing :(

Its benchmark results are similar to Test12 on XWKK5, that is worse than Test10 on XWKJ3 (except the Vellamo browser benchmark).

Just numbers ... but ... the battery saving performance seems to be worse too.

Till now, I only tested the over night battery stats, and Test10 on XWKK5 had more battery loss per hour than Test12 on XWKK5, Test10 on XWKJ3, stock XWKK5 and even stock XWKK2.

So on my phone, Test10 on XWKK5 is not my "kernel/Rom sweetspot".

But I will finish my battery performance tests, before flashing another (SpeedMod) kernel.
[Galaxy S II Original Android Development] planetf1:
That's what I'm on currently, though haven't had a chance to look at power yet -- has to be stability first. Will prob use phone a fair amount today so should be a useful test

[Galaxy S II Original Android Development] lrcquest:
ya, have tried it. Eventhough its not a necessity, it gives peace of mind that all values are stock prior to flashing a new kernel! Mainly for use when coming from kernels with uc/ov options. However, is a good practice imo.

I got got superb battery life from test 12 but also had issues with delays waking up when pressing the home button and a couple of crashes on the lockscreen.

[Galaxy S II Original Android Development] BrandoHD:
It seems that Chainfire has written some safety features into CWM 3.0 to ensure that people don't try to use the new advanced features of 3.0 with the wrong recovery therefore causing countless problems, and rightly so......

The basic features still work like flashing kernels and whatnot, so you have the functionality of CWM 2.0 if you are using any kernel other than CF-Root

---------- Post added at 01:05 PM ---------- Previous post was at 01:00 PM ----------

What is the exact issue, what ROM, is it turning on then off, is it stuck at "obtaining IP address?" have tried the necessary wipes, cache & dalvik? Did it happen directly after flashing test 12, did you try flashing CF-Root or stock kernel to test if it would work then???

I for one have had a very weird issue in trying to upgrade to KK5, I am back on KJ3 using CF-Root for testing, but in my troubleshooting, My Wifi would be stuck at "obtaining IP Address" directly after using Font installer to install Roboto Font, I kid you not....

Just flashed test 12 and my WiFi is still working well, so I really don't know how using Font Installer to install roboto font can bork my WiFi.....
[Galaxy S II Original Android Development] walkergeri:
But on CWM Manager 2 i can make a backup, this isnt an advanced feature :)
[Galaxy S II Original Android Development] BrandoHD:
Really and truly, only chainfire can really answer the queries, or you can use CWM app and boot into recovery and make your back up from there
[Galaxy S II Original Android Development] walkergeri:
yes, this is what i do now :)
[Galaxy S II Original Android Development] iCatchU:
using t12 on stock KI3. stuck at "obtaining IP address"... does wiping dalvik help?
[Galaxy S II Original Android Development] alphahere:
You should always wipe dalvik-cache when changing kernel kernels.
[Galaxy S II Original Android Development] BrandoHD:
What were you doing when it got stuck, did you make any changes (any that required root especially) try flashing the original ROM again and report if that fixes it, that's what fixed the "obtaining IP address" for me
[Galaxy S II Original Android Development] ewokuk:
ok still on test 12. been tweaking wakelocks, got rid of google maps!! and facebook, im down to just 1 now, gtalk_async_conn, is it possible to get rid of this without screwing google backups etc? im using gemini app manager to disable autoruns but not sure which one to stop to prevent this, whatever it is.

also, im still using lite'ning rom 6.1 (only rom ive ever used), wondering if I should consider changing to something else if theres a better alternative, although battery life with speedmod and lite'ning is very good now ive removed all the wakelocks.
[Galaxy S II Original Android Development] globalgpj:
Thank you.

A lot of good responses from everyone.

What's the best way to install cwm v2 ?

I have an old cwmV2.apk?
[Galaxy S II Original Android Development] BrandoHD:
If you flashed CF-Root, then the app is installed on system, just installing the 2.0 apk over that may not work, as when you reboot, you may have 3.0 again

i'm using xwkk5 stock and k16 kernel. quadrant showed me 3900-4100 scores in the past 2-3 days. but today after 2 runs quadrant showed me 4733. i didn't changed anything from the previous runs. how it's possible?
[Galaxy S II Original Android Development] KeesStolk:
Depends of the rom, if it's a no wipe and you don't wipe it manually, all should be safe.

But did you checked you wifi access point / router and do you see your phone trying to connect?

Maybe it's not the S2 but router that is the problem or some kind security encryption?
[Galaxy S II Original Android Development] planetf1:
After test12 hangs, test 10 was at least stable today but I had high drain. With most processes stopped and limited wakelocks, power drain on idle was not much less than with screen on. No hangs though.

Going on to test11 now...
[Galaxy S II Original Android Development] tkalli:
Score usually increases each time you run, if in succession.​
[Galaxy S II Original Android Development] iCatchU:
My router works with my notebooks, Galaxy S and iphone so there should be no problem with it.

My GS2 stuck at "obtaining ip address" and canoot connect to router.....so it should be ths GS2 problem.

Btw, I find the problem suddenly appears after updating busybox. Any idea if the busybox causes the problem?
[Galaxy S II Original Android Development] eseregin:
Moreover, this test mean really nothing... depend not only kernel, even more imo on other things - such as how mount file systems, block size, cache size and contents, ram optimization so on. Even in this case we can see how it is subjective.
[Galaxy S II Original Android Development] donalgodon:
Another option is to install any version of CF-Root 4 which has 2.0, then use another kernel like Speedmod.

That's what I've done in the past to preserve much of the function in 2.0, though not all.
[Galaxy S II Original Android Development] akbarhash:
Yeah so I thought I would leave some feedback for hardcore.

I had k2 - 18 test 12 it was working perfect with jpkj2 stock ROM. I was getting screen on times of around 7 hrs.

Then I flashed xwkk2 and around three times I got the SOD. Rebooted was fine.

The thing is I wouldn't mind but was also getting huge wakelocks. Mainly dhd_dpc. Searched around, it is something to do with WiFi. I realized that I got SOD only when wifi was on. When on data it didn't happen.

I also tried clearing cache and dalvik, after I had the first SOD still it didn't help.

I have now gone back to xwkk2 Chainfire Kernel. Waiting for you to work your magic.

Hope this helps.

I flashed the original rom and it is fixed. Thank you!! (but still don't know the causation..haha)
[Galaxy S II Original Android Development] globalgpj:

Why would you lose some of the functions if you installed it, as described above. Is that because speed mod uses cwm v4....?

Results for SpeedMod / stock kernels

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 SpeedMod kernels in black, I was running on Frankenstein XWKJ3 ROM.

Here are my current results:

(*) running on XWKK5 Frankenstein ROM

So for me (on my phone with my "normal" usage), Test10 on XWKJ3 ROM and Test12 on XWKK5 ROM are the best balanced combinations.

I prefer second combination, as it uses the newer ROM and kernel version and gives to me the best feeling of smoothness.
[Galaxy S II Original Android Development] fenomeno83:
Test 12 in the best. I think can be final release
[Galaxy S II Original Android Development] planetf1:
After generally *excellent* performance/battery with test12 I had to switch due to lockups -- the only kernel I've used to cause such issues.

Yesterday with test10 performance ok but battery life was awful - about 9 hours - albeit with around 3 hrs screen time. I've had a lot better. But stable

Now running with test11 (back to preempt, but without the hrtick change) to see if stable. Battery life so far looking very 12-esque

However yesterday I did freeze 3 apps - beautiful widgets, spotify,astrid -- this didn't appear to affect the battery life on test10 and reduce the high drain, but worth noting any time a change is made.

Hoping test11 is fine today. remain concerned that 12 is causing lockups for a few people.

[Galaxy S II Original Android Development] richyy74:
It_ler, Thanks for all the tests you have done. I would like to point out a few things:

The results clearly shows how unrealiable benchmarks /especially quadrant/ and tests are and how hard it is to mesure performance and battery reliably.

Worth to note: both in quadrant and nenamark test12 seems to gain hugh performance benefit from kk5 rom. Meanwhile test10 looses performance what is hard to understand.

Night use shows a similar trend and again I see a hard to understand difference in the two runs of test10.

In mixed usage contrary to all above test10 drains similar on both roms while test12 drains completly different.

Test10 and 12 is not all that different according to hardcores changelogs.

What I want to say is: if on a single device there is variations like this, I wonder how much different operators/countries/customroms/launchers can change the outcome of the tests.

I used kk5stock undervolted and test8 switching between them mid day since kk5 is out. I did not notice hugh difference in battery life, but test8 is much smoother and snappier. I am still not a big friend of hotplug, and I think some touchwiz and scrolling hiccup is caused by second core hotpluging.

I keep test8 on my phone for now, but I admit Cfroot's CWM

handles external/internal SD much better and friendlier.

Hi It_ler,

I'm here now who has bugged you enough already.

Thanks for your great effort, you helped me a lot in last couple of days.

I'm PM'ed you cause i dont want to flood Intratech's Thread with my foolish questions.

Anyway, back to topic.

I Rooted my phone as you described (having XWJK3, easy rooting toolkit for rooting). i backed up EFS folder and installed Titenium Backup (obviously free version, as i cant access the paid version).

Now i want to proceed with installing Mobile Odin and Speedmod Kernel. can you tell Which version of Speedmod kernel to choose???

*** And before going to Speedmod Kernel i wanted to test root & its facilities and how to control my system, apps & system apps (like freeze, uninstall, and other options). It would be kind if you give me an idea which apps to use to access root, and what i can do with root access to achieve best performance and features from my phone.

And you can give me some links where i can learn more about root and its facilities, cause i'm new to these things. And how to get into CLI mode? Should i wait for learning more or go straight to Speedmod kernel??? Please advice.

Thanks again.
