Hi,

Recently was trying to apply some new ROM. And was trying to do a backup.

View attachment 791021

I got the above message.

Can someone pointed out how to fix this?

Thanks in advance.
[Galaxy S II Original Android Development] CamoGeko:
Try using CMW Manager 2.0 instead, there is an apk floating about here somewhere.

Edit:

I forgot I put it in my dropbox lol

Make sure you uninstall 3.0 first. :D

second core doesnt go offline in test8

@hardcore...

I dont see the second core to be going offline ever in test8...i had seen the same in test3.

sticking with test7 for now.

in my opinion cpu hotplug worked better
[Galaxy S II Original Android Development] hotrad:
noob question guys, Im just new to android flashing.

how do I remove the yellow triangle thingy after installing speedmod?
[Galaxy S II Original Android Development] CamoGeko:
Chainfire has written a guide in his thread on how to do that. ;)

The Facebook app can be easily handled by selecting Chat and then select Go Offline in the menu.

Just like Gtalk, messaging apps tend to drain a lot :P

Problem is not the entire Facebook app, just the Chat component.
[Galaxy S II Original Android Development] BrandoHD:
There is no reason to install a task killer at all, all the user has to do is sign out of the chat, it says in the screenshot that the "chat" is what is keeping the phone awake, not the entire Facebook service, as henriquesb below has said, just enter the chat from the app and hit "Go Offline" the "chat" session would be closed and it won't hold a wakelock...

Most of the features of the app has been disabled because you are no longer on CF-Root, you are using a different kernel and the app is made to work in "conjunction" with the CF-Root kernels, jsut a safety put there by Chainfire, you can continue to use the app with the available functions...
[Galaxy S II Original Android Development] alexkno:
So test 7 was for me on ki8 deodexed stock not as good as k17 or test 6 for battery.

Going now to test 8 hoping it will be similar to test 6
[Galaxy S II Original Android Development] eseregin:
Or even better remove apk at all using Root Explorer or something like it
[Galaxy S II Original Android Development] It_ler:
No, can not confirm.

I did not switch my SIM card.

I have done the following:

1. Flashed SpeedMod K2-18-test8 kernel (zImage file via CWM Manager app).

2. Started directly on reboot into CWM recovery mode.

3. Wiped cache partition and Dalvik cache.

4. Rebooted the phone.

The last few times, I rebooted the phone first time normally after flashing the new kernel.

And then (after the first normal booting) I restarted the phone into recovery mode (via CWM Manager app) to wipe caches.

That's the only thing I remember that I have done different.

I will try it this way again after flashing the next kernel.
[Galaxy S II Original Android Development] hardcore:
That is intentional. The changes in -test8 in theory make it better than cpu hotplug for power management. CPU hotplug has its own overhead. So now the thing is to compare if there is a difference between them.

I might implement a simpler form of CPU hotplug if it does indeed help battery life, instead of adding to the overhead.
[Galaxy S II Original Android Development] shahulvm:
precisely, in my opinion cpu hotplug had a better cpu online/offline profiling

But am not sure about the other areas where it added overhead to drain the battery.

Yes, simpler form of hotplug would be ideal to go with....shall wait :)

Kudos to you!!!
[Galaxy S II Original Android Development] :
Test 8 flies as test 7 but chews more battery both in standby and while actively using it. And today I'm in full signal...while testing test 7 I was at 1 to 0 bars so in theory it should have drained more right?

[Galaxy S II Original Android Development] Vahidmoby:
i think Cpu Hotplug with PREEMPT Mode is the Best Choice for me (with XWKJ3 Firmware)
[Galaxy S II Original Android Development] hansation:
i agree.. my best kernel so far is test7. thank you hardcore!
[Galaxy S II Original Android Development] shahulvm:
+1 i agree as well cpu hotplug with preempt should be good combo for the next version of kernel..
[Galaxy S II Original Android Development] richyy74:
I like test8. Battery maybe a bit worse but I am not sure yet. Smooth as test7 but test7 produced 3600/2050 in smartbench on my phone while test8 is 4400/2250 which is a significant difference even if it is a peace of mind thing only. I have to admit I like the idea of sched_mc and I would like it to prove better then hotplug.

K18test6 was cpu_hotplug with preempt.

Sent from my GT-I9100
[Galaxy S II Original Android Development] shahulvm:
test6 had good battery life and test7 as well..and both were using cpu hotplug.

sched_mc looks good in therory but in reality its not fairing better than the hotplug
[Galaxy S II Original Android Development] hardcore:
Actually I tried both, and in my very short testing, no hotplug was doing same or better than hotplug. But longer usage is needed to really determine it as the battery meter is not very consistent for small differences.
[Galaxy S II Original Android Development] richyy74:
That is exactly what I observed. For me test8 test5 and test3 worked the best.

It could be quite system dependent. I can imagine that a phone with a lot of low load fares better with hotplug while another with higher loads and more deep-sleep is better of with no hotplug.

That said my usage pattern is quite inconsistent sometimes wifi all day, sometimes 3g, a lot of calls one day, a lot of browsing the other. So my results are not for everyone.

[Galaxy S II Original Android Development] brenopapito:
I used version 16 and flash version 18 test 8.

I felt battery is drained much faster.
[Galaxy S II Original Android Development] nicolasf:
I still don't know about battery usage but test 8 seems much snappier than 7. Very noticeable difference when scrolling. (and

I thought 7 was good ;) )

I will report battery at the end of the day.
[Galaxy S II Original Android Development] nicolasf:
Unfortunately even closing chat Facebook uses CPU constantly for me. Checked with Task Manager and top. Even though it's"only" 1 to 3% usage, cpu won't deep sleep and load remains constantly at 1.0.

Disabling auto updates and exiting with back button solves it for me.

[Galaxy S II Original Android Development] snailmale:
I've been on k2-17 test 1 for the past week or so, had pretty stable and good battery life, but just that slightest bit of lag. But I'm very grateful for the great work hardcore has put in!

I've taken a break from exams to test out k2-18 test 8, just flashed it. Let's hope it's even better!
[Galaxy S II Original Android Development] BrandoHD:
Test 8 is great so far, I never really have issues with snappiness but Test 8 sips the battery like whoa, after 10 hours on battery, 40 minutes screen on and a few wakelocks, I still have 89%
[Galaxy S II Original Android Development] :
+1

no rogue apps or wake locks but battery drain is a bit hemorrhagec (is is spelled correctly?) compared to previous speedmod versions.

Nor tested any of the newer version but that's not bad for 10 hours. You have any data on or syncing apps?
[Galaxy S II Original Android Development] BrandoHD:
I have two twitter accounts, two email accounts data or WIFI always on, facebook, google+ (which often holds wakelocks for me) etc, I never turn off sync, phone runs in the night the same as it would run in the day, minus the screen-on time.....

I don't think speedmod installs root, chainfires does . . .

[Galaxy S II Original Android Development] SaneinOne:
Of course it does.
[Galaxy S II Original Android Development] morg01:
. . to be fair its worth installing busy box . . . which chainfires does automatically

anyway . . we're splitting hairs . . .
[Galaxy S II Original Android Development] It_ler:
As you may read in the other posts, you can flash any of the latest SpeedMod kernels.

Or you can use another rooted kernel, such as CF-Root kernel for XW_NEE_KI4 from Chainfire's thread (you already have the link).

If you want CWM Manager app and busybox, then the CF-Root kernel is the right one for you.

If root is enough and you prefer a very fast and battery saving kernel, then you should try the latest SpeedMod kernel.

Good luck !
[Galaxy S II Original Android Development] bkraptor:
Does this kernel have the ability to change the AC charge rate to something like 1000 mA? Is it user configurable or is it hard-coded in the kernel source?
[Galaxy S II Original Android Development] CamoGeko:
Theoretically its possible but chances are it's going to damage your battery. So I really wouldn't advise it. At the moment max setting is 950 mA with rc1 release.

Transmitted from a Galaxy far far away via XDA lightspeed telepathy.
[Galaxy S II Original Android Development] bkraptor:
I think you're actually talking about the setting in the Siyah kernel, which does include the increased maximum current for AC as you correctly stated. My question was related to the kernel discussed in this thread - SpeedMod.
[Galaxy S II Original Android Development] amitoberoi:
Ur results are a big help. Thanks...
[Galaxy S II Original Android Development] carlos67:
While I thank you for putting this test together for all our benefit, please remember that the results are only valid if the phone is placed in exactly the same location for all tests. This way, the battery used by the cell radio should be the same in every case. This gives more credibility to the test results.

I assume you have done this for all your tests so far??

Thanks.
[Galaxy S II Original Android Development] blade3200:
Great job Hardcore.

But in my device and after tests on all the other k2-18 .., your k2-17 test1 is still nº 1 kernel.
[Galaxy S II Original Android Development] AMDPOWERFIST:
thats what i was saying, but then people read the word CHAT from your images and instantly thought you had facebook chat open.....NO the application itself is DESIGNED (EVEN WITHOUT CHAT OPEN) to instantly reopen.... trust me i have done my homework on this.

Use AUTORUN Manager - it kills background services. Its the only way to keep the application installed AND have it not running in the background and auto opening all the time.

AUTORUN Manager IS NOT A TASK KILLER, its an AUTO-OPEN PREVENTER !!!

[Galaxy S II Original Android Development] fidorulz:
All previous kernels should be made available in the original post or at least 2nd post in case people want to fall back and so they don't have to ask other users

Would make some peoples lives a bit easier
[Galaxy S II Original Android Development] byobodybag:
Edit: Wasn't reading... Good morning! :D
[Galaxy S II Original Android Development] BrandoHD:
You are not the only one that has done homework, the chat feature was logged in and causing the drain, that's why it's called "Chat Session" in better battery stats, there is also another service that is called "FacebookService", you are confusing the two, the service doesn't cause any significant drain, whereas the "Chat Session" causes extreme drain.

If you have to install an app to prevent a particular service from starting up, you might as well remove the app and be done with it, you have introduced a catch 22 by having one service running with the sole purpose of eliminating others
[Galaxy S II Original Android Development] dead0:
regarding facebook app, from my testing, if you are using the latest version 1.7.2, the facebook upload manager service automatically starts whenever there is a network connection (data or wifi), even if you have stopped it in task manager and force stop in manage applications. i am using version 1.64 which has the facebook service rather than upload manager and whenever i use the back button to exit, it stays closed and wakelocks.

i am liking the latest speedmod kernel k18-test 8, very smooth. but i do do find when running antutu 2.2 with kj2 rom, the databse i/o and sd card write score is very low when compared to stock kernel or even siyah 2.1
[Galaxy S II Original Android Development] AMDPOWERFIST:
I agree, the chat function DOES cause significant drain. But even if you go into the application > settings > notification unticked, then close the application, it still runs in the background. It also has periodical polling even when notifications are turned off. This causes wakelocks and as such to get rid of those (even tho they might be minor - 1m 30s over 10 hours or so) you need to disable the services in the background. Which app you use for this is up to everyones own discretion.

The application has a number of background services which can be disabled without the app having any issues running when opened by the user, these include:

com.facebook.katata.C2DMReceiver

com.facebook.katana.service.method.APILogging

com.facebook.katana.FacebookWidgetProvider

com.facebook.katana.binding.UploadManagerConnectivity

com.facebook.katana.binding.ChatHibernateKeepalive

com.facebook.katana.FacebookAccountReceiver

The reason i do this, is because i would prefer to open the app myself and check notifications myself when i choose to, rather than have the app sitting in the background causing wakelocks every so often. As much deep sleep as your phone can get - the better the battery life.
[Galaxy S II Original Android Development] BrandoHD:
The app is a poorly written app, but with the trouble you have gone through to eliminate the app running in the background introducing one service to eliminate another and with the use that I have highlighted in bold, you could simply remove the app and use the mobile web page which is as functional as the app, unless you have the app installed to add the pictures to the linked contacts...

But to each his own...
[Galaxy S II Original Android Development] MaGiXeN:
On 18test7 every 1 hour -1% of Battery in deep sleep.

17test1 is a better choice for me, only every 4 hours -1%.
[Galaxy S II Original Android Development] AMDPOWERFIST:
I agree, the app is poorly written. One would expect that when you disable notifications, it would not allow the app to run internet related business in the background still. But i use it quite a bit, for multiple things. Check in's, picture uploads, etc which is more than the webpage has to offer. I also have a second Facebook app called Friend-caster (paid version) which when notifications turned off doesn't run in the background. Each app does certain things better, so having them both succeeds in accomplishing what either app should do effectively by itself.

If only app creators would give more power to the users of their apps without requiring 3RD party apps to solve the issues they leave behind with their poorly written code / app structure and design.
[Galaxy S II Original Android Development] beaver2233:
The facebook app is horrible and as mentioned can cause significant drain... Use the mobile website, much better than the app, and for chat, if need be, download GoChat... ;) simple
[Galaxy S II Original Android Development] coolfire:
I totally uninstalled FB app, and use the mobile version in Dolphin if i need access. FB chat really sux...

Let me check again...so far the best battery life (ofcourse coupled with performance) has been as below

1. k2-18-test7

2. k2-18-test6

3. k2-18-test3

if I see some more posts, than I may try k2-17-test1...

[Galaxy S II Original Android Development] shahulvm:
first and foremost v2.3.3 has os battery drain bug...hence suggest to move to a 2.3.5

1. Wanamlite ROM

2. Simple&Clean

K2-18 test 8 is VERY smooth, but seems to have battery drain issues compared to k2-17 test 1. K2-17 is definitely, noticeably slower, but the battery life is really impressive. I might switch over to k2-18 test 7 to test that later on.

Among k18 for me test 6 was best for battery.

I guess I go back to 17

For me a bit less performance is OK, when I get 20% more screen an overall time. The speed is still much higher as most of the phones and of course much better than stock
[Galaxy S II Original Android Development] Vahidmoby:
i can confirm test 6 is the best So Far for me (with ki4 and kj3)

now i'm 1d10h43m on battery with 2h1m screen on (wifi always on)

and i have 65% battery with Chechrok RevoHD 3.1.1

it's Normal Usage but with heavy usage i got over 6:30 h Screen on with test 6 (8 h on Battery)

i'm happy with Test 6 :) Perfect For every Usage (Normal , heavy)
[Galaxy S II Original Android Development] ewokuk:
test 8 the best so far for me, left phone on overnight, wifi disabled, 3g enabled, phone on 10 hours and only lost 3%!

Preempt_voluntary - ??

Is PREEMPT_VOLUNTARY really giving better battery life :confused:

appreciate an answer with stats as I have read enough theory of it :p

Am going to test back test6 again
[Galaxy S II Original Android Development] Fille84:
Test6 is also the best for me, on the first charge with it I got 5h screen time over 1d. And awake time (I streamed some music with tinyshark) was about 6.5h. Wifi was on all the time.
[Galaxy S II Original Android Development] jsompis:
Test 6 is the best for me too. Got 2days and half on Deodexed XWKI8 about 2hrs screens with 12h wifi on per day.
[Galaxy S II Original Android Development] It_ler:
Interesting.

I lost about 13% with SpeedMod K2-18-test8 over night.

But I had wifi on (and synch and Talk and Skype).

Nevertheless, 13% is too much, as I had only 5% with Test5 under same conditions.

Current battery stats in SpeedMod K2-18-test8:

After 24h (day use and night "sleep" with synch/wifi/Talk/Skype on): 46% left

Awake: 3h 50m 21s

Screen on: 1h 20m 58s

So, it is still better than every stock kernel I have ever had.

But not the best battery saving SpeedMod kernel I had.

Waiting for the next version to test.

[Galaxy S II Original Android Development] planetf1:
It's clearly pretty hard to be certain of which kernel is best -- but my gut feel from using test8 since it came out (ie sat/sun) is that the power drain on idle is worse than test7

Looking at my power usage today -- an usual getup/drive/gym/drive/office definately seems steeper than usual. I was down to 82% with around 40 mins screen time. That's not awful in itself, but what was interesting was that the curve was little different whether the screen was on or off.

No significant (user) wakelocks so I've rebooted to test7 to see if the curve flattens for the next hour or two. So far I think test7 was the best for me or at least close to.
[Galaxy S II Original Android Development] ewokuk:
I spoke too soon. for me test 8 was great in idle overnight but as soon as i opened one of my apps that connects to the net, i found the battery dropping like a rock, and when i check cpu spy, it had spent a fair bit of time at 1200mhz and theres NO reason this app would ever need to do that and im sure it didnt on previous version I tried. guess something to do with the cpu management on this one has caused it to use much higher cpu frequency than on the last one i tried.

Going to try another when i get back home later, k18 test 8 not good for me at all.
