Couple of times in lock screen or when phone is waking up because of incoming call. Once in cwm but i used cmw only twice: for flash cm11 and your kernel. So statistically once in two attempts is quite bad result.

Thats what i did. I had gingerbird. Then i auto upgraded in kies to MG2 @ 624MB. Next steps where:

- root

- temporary cwm

- wipes (data, cache, dalvik cache)

- format /system

- install cm-11-20141118-UNOFFICIAL-codina_ext4.zip

- install pa_gapps-modular-pico(uni)-4.4.4-20141119-signed.zip

- reboot

- install codina_kernel_cm11_20150422_ext4_ace2nutzer.zip

- reboot
[Galaxy Ace II Android Development] ace2nutzer:
Don't use Kies...

use offline flasher ODIN.. take a look in my dev-host

wipe data

and then flash this with odin:

http://rapidgator.net/file/1a9cbc6a665a0ef59e358d11a8a072ce

wipe data

then temp_cwm

cm11

gapps

kernel

reboot system

no need to root.

Hello ace2nutzer and Grüße aus Deutschland! ;)

I'm currently setting up an i8160 for a friend of my wife, stability is more important than performance.

Thus I repartitioned it and went with CM11_ext4 and your ext4-kernel from 20150405, as the changelog stated that this version had no bugs to be fixed in the next release. And my wife's friend doesn't need no experimental +10MB. ;)

Everything went fine, but now I'm having the well known "SystemUpdateService"-wakelock that's perventing Deep Sleep and couses Akku Drain.

Was this fixed in later versions of your kernel (don't even know, if it's kernel-related)?

And if not: Which fix do you recommend? I found one thread that's saying you have to activate the service using a script, another one saying you had to disallow Google Play Services WAKE and KEEP_AWAKE and deactivate three handlers.

Thanks in advance and keep up the good work! :)

Camera + Video rec. working bro.

But i still get blackscreen now, sometimes after play a game. When screen off, i can't wake up my phone using phisical buttons.
[Galaxy Ace II Android Development] ace2nutzer:
Grüße aus Köln zurück !

This is the right Fix:

http://xdaforums.com/oneplus-one/general/guide-google-play-services-battery-t2832525

It's anyway recommended to use latest Kernel at the Moment .. cause of fixes on LCD Driver.. wich can cause Colored Bars on LCD .. (Not dangerous, but maybe LCD can freeze, due to too aggressive Pixel Timings)

That's good, after playing a game it's normal when u've blackscreen.. if it's a game what use very much RAM .. then it's just OOM (out of memory) I'll try to improve minfree values a bit more.... if it didn't help, then i'll re-implemented zRam with LZ4 Compressor...

So the Q.: have u turned off the Screen after playing a game, but blackscreen was already present ? If yes, it's normal..

But anyway take a look if the blackscreen also appears when u're not running too much apps (Multitasking) and when not playing games.

I8160XXLL2 Heimdall

Hi all,

First off thanks for all the development work you guys put in this.

Now for my (very noob) question... I'm trying to update my gf's Ace2 (XXLL2) to a custom ROM for more performance (and less crap).

As I've currently no Windows PC at my disposal I'm wondering if I can do this using Heimdall.

Say that I've I8160XXLL2_I8160DBTLL2_UN-ROOTED_ace2nutzer.tar.md5, should I be able to use Heimdall to flash the contents of this tar to the right partitions on the device? What are the correct mappings between filename and partition? (Kernel is quite obvious, but I need to be sure...)

Thanks for any pointers.
[Galaxy Ace II Android Development] exodius48:
I usually get blackscreen when play Modern Combat 4. Yes blackscreen appear when I turnen off screen.

If i dont play game / multitasking, blackscreen doesn't appear.

So i think you're right, its from OOM.
[Galaxy Ace II Android Development] reinouts_s:
Never mind, I got hold of an old win7 netbook and succeeded to run Odin and I was able to install the I8160XXLL2_I8160DBTLL2_UN-ROOTED_ace2nutzer ROM. However, this doesn't give me access to CWM recovery so I cannot follow the procedure described in #9. What am I missing here?

Thanks!

[Galaxy Ace II Android Development] supachris:
Dear frieds,

it was really cool with ace2nutzers kernel and ROM, but today I got my new phone: The S4 mini, and first I wiped all Samsung **** from it and installed custom kernel with f2fs and CM12.1 and this phone runs like hell with 1.5GB RAM and LP. And it has a light sensor!

So I have to say goodbye and will sell the great Ace 2 with this great kernel and ROM to a friend.
[Galaxy Ace II Android Development] riedlZ:
Hey thanks for the great kernel and rom :good:

I hava an OnePlus One as "main" phone and want to use the Ace 2 as a media player in my car. I'm the type of person which wants to get the best out of everything so I have some questions :angel:

As said I want to use my Ace 2 as a "media only" phone in my car. This means for me:

play music

record videos (dash cam)

view images

I want to slim down the rom to the absolute minimum. That means the only apps i want to have installed are:

launcher

media player

gallery

camera

No telephone, contacts, sms, email, google apps, calendar etc.

So the first question is, do you have some kind of a list of system apps who are REALLY mandatory for the phone to work?

Secondly my music library is about 60GB right now and growing. Having a 64GB sdcard seems to make the file access a bit slow on the Ace 2. Can you recommend any specific settings for that kind of data storage (many, small, read only files)?

With the above in mind, i read that the F2FS filesystem has better write but slower read speed. Would it be better for me to stay on ext4? And is F2FS a SDCard file format at all or did i misunderstood something? Would i lose all data on the sdcard if i would change the format to f2fs?

And last, do you have any lightweight and fast app recommendations for my 4 apps that i need? After some reading i would currently go with the following:

Nova Launcher

Shuttle Music Player

Quickpic

Google Camera

Sorry if this is not the right place to ask, but i thought who could answer performance related questions better than a kernel / rom dev :D
[Galaxy Ace II Android Development] drhay:
(broken english)

Hi.

Thank you fluffi444, i downloaded 3-part rom, okey.

ace2nutzer; i have two question. If you can answer I would appreciate.

Two days ago i had clean installed like this: i installed 3-part GB, then installed 4.1.2 MG2 rom (before i used MH1). After that i installed your CM11 and latest kernel (04.25) with all f2fs, as you wrote. Now nearly everything is fine but as i sad i have two questions.

1- In opera mobile for android (not opera mini) and blue-type mail (email app) the phone is forcing, very slowing down especially mail app. I had already this situation before clean install. Now in case, is it normal you think? If it is normal or it is only app issue, no problem, ok.

2- Some times your writing in "next version", updated minfree values. What does it mean? Yes I know minfree app but don't use it. Would you recommend to use it for speed? If yes, in your post 1645 page 165 values is still available/effectual?

Thanks for all your work.

(my phone: i8160, cm11 11.18, kernel 04.25, in dalvik, 1200 mhz, no gpu oc, no game, sys/devices = ws2401.0, lcd/panel/lcd_type = SMD_LMS380KF01)
[Galaxy Ace II Android Development] ace2nutzer:
@up

1 &2

It's normal .. Ace 2 has only 768mb ram ... And for user apps incl. Launcher only 629mb.

Next build will have new minfree values + enabled zram @ 50 - 200mb (need to test with real racing 3) and the system should work better, also better multitasking, of coast for a little bit more power consumption.

I can really suggest to everybody to don't edit minfree values.. This is quite complex and if u don't now what u do u'll only decrease speed and stability !
[Galaxy Ace II Android Development] pablo.see:
For me, best minfree values are: 40,50,60,70,120,160 They are taken from codina_kernel_cm11_20150320_f2fs_ace2nutzer kernel
[Galaxy Ace II Android Development] ace2nutzer:
Yeah they are also good.. but next build will have better one... these:

20,30,40,50,70,90 values in MB

With that Values RAM is running at max. efficiency ;)

Btw: of course with Dalvik ! .. don't use buggy ART ;)

I seem to have a wi-fi problem with your latest kernel. After some time, the phone won't load any webpages and facebook doesn't work while on wi-fi. After disabling wi-fi and enabling it again, everything works fine. I didn't have these problems on the previous kernels, and also I'm sure it's not a router problem, because my laptop and tablet work just fine on the same connection. Any ideas?
[Galaxy Ace II Android Development] ace2nutzer:
Thx for Report ! Well this is probably another side effect by using HWMEM=74 instead of Stock: HWMEM=84 ...

Have u actually 640MB RAM ??

btw: it's fixed in next release ... just take a look from time to time on second post by: "Next Version" ;)

btw2: next build is an atomic kernel .. it'll damage the whole world :cool:
[Galaxy Ace II Android Development] gepel:
[MENTION=5840412]ace2nutzer[/MENTION] , is there any chance for add the fix for web streaming in some next version of your kernel ? If this is not possible , can i use the latest version of chrono rom with your kernel ?
[Galaxy Ace II Android Development] ace2nutzer:
If it works yes.. u'll find it in next build .. .. but good idea.. i think i'll add that fix in the kernel package.. then it's permanently added in the rom .. even if u'll use another kernel... instead of re-upload the wohle CM 11 build ... because i've a slow internet connection :o (only 6M/bits .. upload is only 90kb/s)
[Galaxy Ace II Android Development] Matteo90:
Yes, I'm using 20150425 and I have 640MB. But I'm looking forward to the mighty Next Version! :good: :D
[Galaxy Ace II Android Development] Alex_Gamer:
Amazing!! ?
[Galaxy Ace II Android Development] ace2nutzer:

Fix for Live Video Playback - Thanks [MENTION=5371721]Epirex[/MENTION]

Enjoy that explosion of Performance ! :good:

Nuclear Info: That build include the Fix for Live Video Stream.. it's placed in /system/lib and it will fix that Bug on every 4.4x ROM.

Even if u change / update the kernel !!

Info 2: The Fix in ONLY in this Build here... next build and so on. i'll remove the fix.. because it's then already stored in your ROM / Phone.

An other way is to install the latest CM11 by [MENTION=5695278]ChronoMonochrome[/MENTION] .. it contains also the Fix ... but actually i didn't test if this Kernel here will work properly on latest CM11 ! - For just in case stay so long on 18/11 with the Fix here.. until i'll test + adapt. my kernel on latest CM11 !

btw: Big Thanks [MENTION=5695278]ChronoMonochrome[/MENTION] for helping me with git commands how-to add uksm :D

[MENTION=5840412]ace2nutzer[/MENTION] This is the first time I installed a new kernel right after your release tonight (at least 15 minutes or so). To make it short there are no issues so far, Link2SD is fine also. Thumbs up ;)

Thank you very much!
[Galaxy Ace II Android Development] gepel:
Respect goes to Ace2Nutzer for his amazing work. Everything seems to work smooth and fast.

And one hint that i found. If you like to view videos on youtube without pixelization. At 1st time that you open a video just press the timeline somewhere in the middle before the video starts. In case that the youtube is allready has oppened before the trick just close the app from app switcher and give another try .. Enjoy !

P.S. if the 1st video starts with advertizement try again (closing the app from appswitcher)
[Galaxy Ace II Android Development] MrBlackCore:
Why did you revert the ram thingy? Was there a problem or..??
[Galaxy Ace II Android Development] ChronoMonochrome:
@up, he told me about bug with dissapeared photos in gallery, also there were problems with wifi due to that patch.

This looks very interesting... however I have heard about reboots on 3.0.101 kernel due to this.
[Galaxy Ace II Android Development] ace2nutzer:
yes, - 10MB due to the revert of HWMEM .. it was buggy... and - 1MB because of adding options to the kernel like: swap, uksm, zram and built with a lot of optimizations .. like -Ofast and so on .. wich make the code of the kernel bigger .. but it's worth .. due to better performance :)

as for non working m.youtube.. i'll update soon my CM11 Version to the latest from Chrono .. then everything should work perfect ;)
[Galaxy Ace II Android Development] sorset:
Hi, Im using latest version, I have problem in NovaThor Settings , non of screen options , like 2Tap2Wake and Sweep2Wake no longer is working...
[Galaxy Ace II Android Development] ace2nutzer:

Yeah it's :o And so far no reboots :)
[Galaxy Ace II Android Development] MrBlackCore:
Couldn't install on USB storage or SD card. That pops up when I'm downloading from playstore. Using latest f2fs

I installed link2sd to see how much free space I have and on external SD I have 0% free (I am swapping storages BTW) I'm also using chrono reparted script so I have 95.16mb on external SD.

Also usually I have 280+ free ram now I have 140 with the same apps installed... Something is very wrong.
[Galaxy Ace II Android Development] ace2nutzer:
i'm using for real sdcard0 only 2,5MB and no problems here.

go to cwm and format sdcard0 as vfat .. then everything should work fine.

@ RAM have u some Problems related to Multitasking ? I don't know why it's "very wrong" when u've now less ram free ...

that Value changes every second.. . but i've changed minfree values for more efficiency + enable zram with 300MB ..

so u can check with term. emulator how many ram is used / free .. and how much swap is free ;)

btw: on Dalvik here everything is fine... :)
[Galaxy Ace II Android Development] exodius48:
Just suggestion to you, if you update your CM11 , please use twrp instead of cwm to resolve blackscreen bug in cwm.
[Galaxy Ace II Android Development] ace2nutzer:
nope, it's then not fixed.. it's just a workaround .. and problem for cwm is still there ... :o

Anyway, i did tonight some stability improvements for CPU / GPU ... maybe some of u will have more luck on next build :p
[Galaxy Ace II Android Development] exodius48:
Yes i still get that bug, blackscreen in cwm + offline charging animation not working. :(

I hope next build will be resolve that problem. :D
[Galaxy Ace II Android Development] MrBlackCore:
It is formated as vfat. I understand about the ram but what about playstore?
[Galaxy Ace II Android Development] hector_yo:
About your problems with SD, maybe it's something like what happened to me ( #1675 ). if it is, the only way I could fix it, was forgetting about repart.zip and use the commands to repart that are in one of the first posts.

Sorry if my english is too bad.
[Galaxy Ace II Android Development] ace2nutzer:
Okk, but u say 100% full.. System can't work properly when on sdcard0 are at least 2mb free :)
[Galaxy Ace II Android Development] MrBlackCore:
here so you can see for yourself.
[Galaxy Ace II Android Development] ace2nutzer:
Hmm as i said u need to check what is causing 0% free for sdcard0 and the move it to sdcard1 ... As for 2. Partition for me works:

Btw: some apps from play don'f give care if sdcards are swapped or not !

Fix: swap storages again (to stock) .. Install all the apps u need and swap storages again... Works 100% .. So really no need to waste useful 100mb space for sdcard0 ..

2mb is enough for sdcard0 .. See my Screenshot...

Just make with gparted a second Partition on ext.sd as primary Partition and format it @ ext4 ... That's it ! ;)

PS: @ free: everything fine.

After I installed Kernel as of 01.05., the phone does not switch to Deep Sleep acc. to CPU SPY.

Did try 3 times with clean installation.

(Maybe I´ll try old kernel again.)

Strange: While doing these trials, I automatically reinstalled all Apps, that have been stored on my Google account.

The fourth time, I did avoid automatic reinstallation. This time Deep Sleep is working.
[Galaxy Ace II Android Development] hanker_de:
Hello!

Perhaps the infamous SystemUpdateService Wakelock? You should experience no deep sleep as soon as Google Play Services update themselves.

You can avoid this wakelock by dissalowing Google Play Services 'Keep Awake' and 'Wake Up' in Privacy Settings /Guard. Worked perfectly for me.

Greetings from Germany

René
[Galaxy Ace II Android Development] Eleichstetten:
Will keep that in mind. Maybe that´s a helpful information in future.

This time it seems to be different.

I did now reinstall all Apps that have been automatically installed before.

I started with all Apps that carried a "Google" in their name.

All went fine. Deep Sleep kept on working.

Then I installed the one and only App that´s not from Google: "GSAM Battery Monitor" together with the supporting part for

rooted devices.

==> No Deep Sleep anymore.

Well, I´m using that App with other devices without any issue, but maybe the special Kernel and this App don´t fit.

The Root Companion seems to be the root of all evil.

CWM 6.0.5.0 - "mounts and storages: enable f2fs - etx4 conversation"

Hi,

question: I would like to try f2fs+CM11. At the moment I have (from a prior CM11-install) CWM 6.0.5.0. I dont have the entry:

"- mounts and storages: enable f2fs - etx4 conversation" (*)

there. I already installed the most recent f2fs-kernel from ace2user.

Where can I get the correct CWM version for migration? I already tried "temp_CWM_6.0.2.8.zip". After flashing this zip it directly (soft??-) boots into 6.0.2.8

- also without option (*). Furthermore this recovery seems to be correctly capable of using sdcard0/1 (from the prior CM11-install). Also with a full reboot the

CWM is again back to 6.0.5.0.

Therefore: How can get option (*)

btw. - how can check via "adb shell" into CWM that f2fs support is present (cat /proc/filesystems does not contain f2fs) ?

Thanks,
[Galaxy Ace II Android Development] ace2nutzer:
@ up

install ace2nutzer f2fs kernel .. then power off .. and boot into recovery .. then u'll see the right menu ...;)
[Galaxy Ace II Android Development] jungp:
Hi,

Thanks for your reply.

However, I did exactly this. I suspect that the option is only there if f2fs support is present, right?

How can I find out that the f2fs-capable kernel is running in recovery?

Thanks
[Galaxy Ace II Android Development] ace2nutzer:
1. all kernels contains in filename: "f2fs" are full f2fs capable .. ace2nutzer f2fs= full f2fs support: also for system.

2. all those f2fs kernels from me, have as recovery: cwm: 6.0.4.9 ....
[Galaxy Ace II Android Development] jungp:
Ok. This means that I have to check whether flashing your f2fs-kernel with my current cwm-6.0.5.0 was really successful. I will check this.
[Galaxy Ace II Android Development] ace2nutzer:
Yes, i forgot to mention: u can install f2fs kernel with usual ext4 cwm: 6.0.5.0 :o
