Here too. All SD Apps disappeared. Back on 0130, due to no time for msg searching at the moment.
[Galaxy Ace II Android Development] MrBlackCore:
here
[Galaxy Ace II Android Development] ace2nutzer:
@up

thanks for the logs... but i need logs from the 03/07 and not from 03/02 .. and only if u have disappeared apps from sdcard ..

And do that pls with "su" .. one log is empty.

btw: have u still battery draining with latest kernel here ?? i've take a look into your battery stats.. and didn't see smthg very weord.. maybe just google play services... Follow pls the fix for Google play services ...

therefore i'm still waiting for logs for latest build with disappeared apps from SD Card ....:cowboy:
[Galaxy Ace II Android Development] MrBlackCore:
They are from /07 and I do have disappared apps from sd. XDA app is one of them. Im getting the longs via my laptop with adb and no matter what I did the log is empty. Gonna flash /07 again and give you the logs. gonna do it right now. As for the battery drain, with /07 is a bit better but still too much. And I did the fix for google play services right after it was posted on here.
[Galaxy Ace II Android Development] ace2nutzer:
ok thx !!

u can post also one BBS log later ...- i'll check again for problems.. but don't forget to install the app as system app.. and grant root rights.. to make it working properly ...
[Galaxy Ace II Android Development] MrBlackCore:
Just flashed /07 again and these are the logs. Its /07 f2fs ART with swapped storages . If there is something wrong again then Im doing something wrong and some1 with more skill than me should do it instead :D I will post BBS stats again after 1 day usage
[Galaxy Ace II Android Development] Bito21:
Ace2Nutzer, same problem on my Ace2.

after flash the 0307 kernel all apps on SD didn't apear.

I also use Link2SD and cannot mount the second partition.
[Galaxy Ace II Android Development] miryn:
Soooooo fu*kin what??
[Galaxy Ace II Android Development] ace2nutzer:
What's the filesystem on it ??
[Galaxy Ace II Android Development] Bito21:
Ext4
[Galaxy Ace II Android Development] ace2nutzer:
thanks again for the logs. So far i can't see the Problem... but i need also/now kmsg .. from latest build... not last_kmsg :o

btw: @ disappeared Apps from sdcard:

U guys with such issue.. can u pls tell me wich build version u need ?? Then i can make a test build ... ;)
[Galaxy Ace II Android Development] Bito21:
Ace2nutzer, can you mais a teste build for 0307?

Everything works fine on 0302 kernel, but on 0307 all apps on SDcard disapear and Link2sd doesn't mount the second partition.

If i can do anything to help, just tell me.:D
[Galaxy Ace II Android Development] tbronco75:
Hi ace2nutzer,

I wanted to flash your latest codinaf2fs firmware and after flashing, inclucing reparting I get for the first start always a question:

TYPE PASSWORD TO DECRYPT STORAGE

I´ve just reparted to GB, upgrade to JB, root and CWM and then your flash files, but I can´t get go far.

What can I do?

EDIT: I´ve found the fault: I forgot to Format to F2fs Data :)
[Galaxy Ace II Android Development] MrBlackCore:
hope this works
[Galaxy Ace II Android Development] ace2nutzer:
@ tbronco

this is very weird.. i don't know :confused:

In last log i believe to found the issue. but anyway i'm not so sure if this is the reason for the issue.

Okay.. i'm ready to build some test builds.. i just need to know wich version of kernel u need .. ---> codina ext4 ???
[Galaxy Ace II Android Development] MrBlackCore:
codina f2fs
[Galaxy Ace II Android Development] tbronco75:
yes it was f2fs, but now its ok after format f2fs data. I thought something were wrong, but now its ok.

I had by repart at rm 11 a problem, there was an error for partitioning. after that i had this misterical error.

Now I flashed it without repart and is going very well
[Galaxy Ace II Android Development] Bito21:
Please make a F2FS teste build.
[Galaxy Ace II Android Development] ace2nutzer:
Test Build 1

inclusive latest changes for next build ... see Post #2 "Next Version" .. all done, excluded "max ram"

Pls test if the app problem on sdcard is fixed .. .thx !

Test Build 4

http://d-h.st/jqmQ
[Galaxy Ace II Android Development] Bito21:
Test build 4 is working :D:D:D

Thank you.
[Galaxy Ace II Android Development] MrBlackCore:
Yeah, thats the one! Apps are back. Gonna test it for other issues
[Galaxy Ace II Android Development] ace2nutzer:
Great ! Thanks too for hard testing guys [MENTION=5715104]MrBlackCore[/MENTION] for u also working test build 4 ???
[Galaxy Ace II Android Development] MrBlackCore:
Yes thats the one. Apps are back and working. Gonna test it for other issues
[Galaxy Ace II Android Development] miryn:
Can we download the latest version from FTP already? Is it final latest 03.11?
[Galaxy Ace II Android Development] ace2nutzer:
New Build is Up !!

Changelog:

20150311:

Fixed disappeared Apps by using link2sd - thanks [MENTION=5715104]MrBlackCore[/MENTION] & [MENTION=5977250]Bito21[/MENTION] for testing

LPA: increased Voltage from 1V @ 1.0625V

Fixed Blackscreen Bug on s6d and ws2401 LCD Drivers (all)

Revert LCD Freq to Samsung Default 50MHz

Added Interface for Boosting LCD Freq @ 57MHz (preset in 01optimization file)

Updated 01optimization file

Minor Kernel Tweaks

New File in init.d: 01gpu_oc (more user friendly)

Added nice Offline charging graphic from Philz Recovery

Increased Brightness a bit for Recovery, CM Logo and Offline Charging

Wipe cache + wipe dalvik/art cache is recommended

Pls only Download the latest Build from FTP if u see in Thread Name the latest Build .. because when the file is not 100% uploaded u can't see this on FTP server.. u can Download anyway .. but the .zip package is incomplete then.. - Right now, done ! (u can download)

Ehm yeah.. we can say final Build.. because i think it's now bugfree.. but i will anyway continue building new releases ... for some extra nice features like more ram, maybe more stability on OC.. and maybe some small correction in LPA Voltage.. - that cause for me sometimes bad sound by lock-unlock after long playing music with screen off.. but i think that bug i can fix it.. and at least it's not present on every Phone ;)

Therefore, stay tuned ;)
[Galaxy Ace II Android Development] dixee:
great release..

also yesterday when install version 20150307, the other issue is broken download progress in some application when screen goes off.

so i switch back to version 20150130, its doesn;t break download progress

i don;t need to rush to get more available ram, for me balanced performance, all basic function and feature worked properly is enough for me :D , my ace2 already has a small ram and today phone has a bigger ram

maybe i will try this latest release, btw thank you for the great work :good:
[Galaxy Ace II Android Development] Bito21:
Ace2nutzer, is there any difference between test build 4 and 0311 version?
[Galaxy Ace II Android Development] jhafner:
Hi ace2nutzer;

First, thanks for your constant work on the kernel.

Second, I have read a comment from you stating that decreasing lcd clock gives more battery duration, so what happens if we decreased lcd clock from 50MHz to 40 for ex.?
[Galaxy Ace II Android Development] Bito21:
Ace2nutzer, I have a problem with 0311 version that on test build 4 didn't had.

On 0311 version I cannot mount the second partition on link2sd.

Can you please help?
[Galaxy Ace II Android Development] Souffre:
Same for me. My 2nd partition is now ext4. I couldn't try test builds cause I need codinap
[Galaxy Ace II Android Development] ace2nutzer:
Yes, cleaned sources before building and disables some test options in defconfig.. excluded the Option to make it working the ext4 for link2sd .. but if the Problem is still present, then it seems that we should re-enable an second option too.

Okay i'll build again some test builds to find the second needed option .... :)

Yeah it'll probably safe more power.. but the Phone is then nearly not usable. The Responsiveness is then very horrible .. also much laggs, slow scrolling and more screen tearings ...

On my Kernel u'll find only two LCD Freqs: 50Mhz (Default) and 57Mhz (Boost) ... if anyone have screen tearings or laggs .. even on primitive 2D Games, then u should set LCD CLK @ 57Mhz .. then it's again smooth... to do this, just take a look in file: 01optimization in init.d section .. remove the "#" before "echo 1 > sys/kernel/mcde/lcd_clk, safe and execute the script as root or just reboot the Phone. .. to revert again to kernel default: add again the "#" or do: echo 0 > .......

But after using 57Mhz (LCD Boost) and if u've Blackscreen bug, then it's better to disable the LCD Boost to fix blackscreen bug...

That change + sysfs interface was needed to fix blackscreen bug for most s6d lcd drivers, even on cwm ;)

[Galaxy Ace II Android Development] miryn:
[MENTION=5840412]ace2nutzer[/MENTION]

Is there a way to decrease vibration strength in kernel? Or maybe easier, is there some init script for that? I'm asking cuz my rom doesn't have that option..
[Galaxy Ace II Android Development] soko3:
[MENTION=5840412]ace2nutzer[/MENTION] can you change minfree values a bit and improve multitasking...

for example, when i'm using opera mini, and switch to rocket player, switching back to opera from 'recent apps' takes a lot of time, and many times opera and all opened tabs are killed... that's very annoying

this problem is present since 0303 build

so i wonder if you can make more apps staying in ram..

it's pointless to have 230-250 mb of ram free, and have worse multitasking than with 100mb on previous versions
[Galaxy Ace II Android Development] greeceeeee:
I installed 0311 and apps moved on sd disappeard...
[Galaxy Ace II Android Development] bebolint98:
[MENTION=5840412]ace2nutzer[/MENTION] I install the 03/11 ext4 kernel but I got a problem.I use the phone about 10 minutes,download apps from play store the phone is freeze,and I can only restart with the power button and when the phone is booting it's write:android system updating optimizing application 1/1 next to the text rotate a circle

then suddenly freeze and the phone not boot up.I install the kernel three times but same problem, I haven't got this problem on older version.What do you think what is the problem?

Sorry for my bad english!
[Galaxy Ace II Android Development] ace2nutzer:
okk.. i'll check this .. I'll pmed you later with a test build.

Yeah that's what i'm meaning all the time... we can't have both things, much free ram and good multitasking.. we've only 630MB :)

But okk, i'll improve Multitasking ;)

hmm maybe not enough free space on sdcard0/1 or even on /data ... but /system also possible. Try first: wipe cache and wipe dalvik cache.

btw.: i know in latest build apps are gone again by using link2sd ... but can pls someone test the test build 5 ... what've posted here ?? it's codina f2fs ...(look some posts before here) [MENTION=5977250]Bito21[/MENTION] [MENTION=5715104]MrBlackCore[/MENTION] :o;)
[Galaxy Ace II Android Development] MrBlackCore:
Um... I have no problem with apps with the latest build. Everything works great. What is there to test with test 5?

Ok I just flashed test 5. Apps are movable to sd card but crash when I try to start them.

Aaaaaand after restart the apps that I moved to sdcard disappeared
[Galaxy Ace II Android Development] ace2nutzer:
on latest build the problem is back .. i think u're still on test build 4 .. that works fine.

Well therefore test build 5 is also wrong... thx for testing .. i'll make new build 6 !
[Galaxy Ace II Android Development] r_e_n_e:
Ok thanks. I will download apk and publish the logs then.

Anyway... I installed "codina_kernel_cm11_20150302_f2fs_ace2nutzer" kernel, but it doesn't help.
[Galaxy Ace II Android Development] ace2nutzer:
wich kernel version u need? codina ext4 ?? Then i can make test build for VPN :)
[Galaxy Ace II Android Development] MrBlackCore:
Well I guess you are right. I mean yesterday when you uploaded /11 and I flashed it the sdcard apps were working fine. Now I flushed /11 again and apps were still there and usable. But after restart they are gone again. Sooooo Im home now - hit me with them test builds
[Galaxy Ace II Android Development] ace2nutzer:
THX ! But on Test 4 even after restart still ok ??? This is now very important to know !
[Galaxy Ace II Android Development] MrBlackCore:
ummm, dont know. Let me check that but I need the test 4. I think I still have it. Gonna tell you if it works in 5-6 min
[Galaxy Ace II Android Development] ace2nutzer:
OK :o:D
[Galaxy Ace II Android Development] MrBlackCore:
Well... with test apps are still there after restart but when moved from sd card to phone they crash and need phone restart to start working. But in general moving apps work before and after restart.
[Galaxy Ace II Android Development] ace2nutzer:
Well thx ! i think this is normal .. reboot is required then when moving back to phone... but it's good that after reboot the apps are still there :)

Now i'll build test 6 .. i hope it's okay then.. if not, one more try but then it works ! VPN should later also working...
[Galaxy Ace II Android Development] drabollo:
Hi Ace2Nutzer .

How can I migrate between your kernel and Chrono ? Because when I try "install zip" from Chrono to Ace2Nutzer in recovery it always ends with bootloop :crying: btw. which version of your kernel is the best for GPS tracking,car navigation etc. ?
[Galaxy Ace II Android Development] ace2nutzer:
When bootloop: Flash ace2nutzer kernel again ... and if it didn't help.. then flash first ODIN Kernel from my dev-host .. then latest kernel from my FTP ..;)

About GPS: I've never touching something .. because it's simply working well :o:D
[Galaxy Ace II Android Development] drabollo:
Thanks :)

I'll try this method when I got home from work ;) btw. I need both your kernel install by Odin or just first one?
[Galaxy Ace II Android Development] Bito21:
With Test 4 all apps are working after restart.
[Galaxy Ace II Android Development] ace2nutzer:
odin kernel with odin.. and normal kernel from ftp with cwm .... don't forget to choose the right version.. codina/p and ext4/f2fs ... this is not universal kernel (and works only with CM11)

[MENTION=5715104]MrBlackCore[/MENTION]

build 6:

http://d-h.st/exx

(codina f2fs)

pls test again if apps are okk even after restart ... if u can, or somebody else: pls test also if VPN is working ...
[Galaxy Ace II Android Development] ace2nutzer:
yes i know.. mrblackcore already test this.. but i need to know if it's also working on build 6 .. because of minimal config :D
[Galaxy Ace II Android Development] Bito21:
[MENTION=5840412]ace2nutzer[/MENTION] after test build 6 still cannot mount the secon partition on Link2Sd app :(
[Galaxy Ace II Android Development] ace2nutzer:
Test Build 7

http://d-h.st/ODB3

codina f2fs

I hope it works now... :)
[Galaxy Ace II Android Development] MrBlackCore:
Nope :( Same problem
[Galaxy Ace II Android Development] Bito21:
Bad news :(

Still the same problem...
[Galaxy Ace II Android Development] ace2nutzer:
And this?

http://d-h.st/YHyf
[Galaxy Ace II Android Development] MrBlackCore:
No luck. Same problem
[Galaxy Ace II Android Development] ace2nutzer:
Damn ! i believe i've mess it up ! :mad:

Sorry for that much testing.. ;)

Another try:

http://d-h.st/ulIY
[Galaxy Ace II Android Development] MrBlackCore:
well there this might be the one. After moving an app to the sd card it crashes like 5 times but in the end it works.
[Galaxy Ace II Android Development] ace2nutzer:
hmm well, but it sounds not optimal :) .. are u sure that with test 4 moving the same apps like now it doesn't crashes ???

If it was better with test 4 (no crashes) then i can make another test build ...

try this: deinstall Chrono App .. and remove all init.d scripts ;)
[Galaxy Ace II Android Development] MrBlackCore:
Crash only happens if I dont restart my phone after moving apps. After restart they work without crashes. With test 4 there was no problem with crashing before or after restart. And I did move the same apps ( 9gag, xda, root uninstaller and 2-3 smaller apps)

---------- Post added at 01:48 PM ---------- Previous post was at 01:42 PM ----------
[Galaxy Ace II Android Development] ace2nutzer:
Thx ! Then we're not done ! :D

I really don't like a half working system :D

I make now new test build ... don't give up :o

After that, if it works again correct, then i can make new realease with also fixed VPN (but i've till now, no confirmation) and optimized Multitasking :)
[Galaxy Ace II Android Development] miryn:
On latest version (11.03) there's pretty big tearing in 2D games like flappy, impossible game; less in settings, etc.

But the battery life at deep-sleep is great!
[Galaxy Ace II Android Development] ace2nutzer:
U probably missing what've writing before in some posts ago after posting the release...

Fix for tearings:

go to /system/etc/init.d and open the File: 01optimization and change this:

# LCD Freq Boost (50 @ 57MHz)

# Remove here below the "#" to enable Boost

# echo 1 > /sys/kernel/mcde/lcd_clk

in

# LCD Freq Boost (50 @ 57MHz)

# Remove here below the "#" to enable Boost

echo 1 > /sys/kernel/mcde/lcd_clk

then save and reboot... OR just execute as root the changed script ;)

[Galaxy Ace II Android Development] drabollo:
Frezzing Chrono settings app in Titanium and flashing your kernel then finaly do the trick :)
[Galaxy Ace II Android Development] MrBlackCore:
When trying to move app to sdcard error pops up : Couldn`t move app
[Galaxy Ace II Android Development] ace2nutzer:
Test Build 10 ! :D

http://d-h.st/NKuw
[Galaxy Ace II Android Development] MrBlackCore:
Well this time I can move apps but they crash and after restart they are gone

Do you need some logs?
[Galaxy Ace II Android Development] ace2nutzer:
No not needed actually .. thx ! We're nearly done... now it's rebuilding from scratch.. u'll have in 30 minutes hopefully working build. ;)
[Galaxy Ace II Android Development] ace2nutzer:
Test Build 11

http://d-h.st/NoQO
[Galaxy Ace II Android Development] MrBlackCore:
Nope, still the same. Crash after move, gone after restart.
[Galaxy Ace II Android Development] ace2nutzer:
http://d-h.st/Swhu
[Galaxy Ace II Android Development] MrBlackCore:
Nope, same problem. Move-crash-restart-gone
[Galaxy Ace II Android Development] ace2nutzer:
http://d-h.st/uKIS ;)
[Galaxy Ace II Android Development] MrBlackCore:
Same story. Apps are gone after restart
[Galaxy Ace II Android Development] Bito21:
It's working :D:D:D
[Galaxy Ace II Android Development] MrBlackCore:
how did you do that. My apps are still crashing after I move them
[Galaxy Ace II Android Development] ace2nutzer:
it should work.. because it has same config like test build 4 !

Try wipe cache.. and if that didn't help, try also wipe dalvik cache !
[Galaxy Ace II Android Development] Bito21:
I don'tknow.:confused:

I've just flashed test buid 13 and all aps are there after restart and working.

I even moved some apps to phone and move again no SD card and still working.

No crashes...

---------- Post added at 07:12 PM ---------- Previous post was at 07:10 PM ----------

[MENTION=5840412]ace2nutzer[/MENTION] is mandatory to wipe cache?

I haven't done that...
[Galaxy Ace II Android Development] VRDRBR:
what is the exact reason for going from 57hz @ 50hz? it's feels less smooth when scrolling on homescreens or in options/browser
[Galaxy Ace II Android Development] MrBlackCore:
Yes, after cache wipe its works. Guess my phone does not like me anymore after all the flashing :D
[Galaxy Ace II Android Development] Bito21:
Today I didn't had the possiblity to test all version released by ace2nutzer :(
[Galaxy Ace II Android Development] ace2nutzer:
Only after faced FC Apps or random reboot !

This is needed to fix the famous "blackscreen bug" on some phones with s6d lcd drivers ... but if u never had a blackscreen.. then u can set the Freq again @ 57Mhz ... just take a look some posting here before.. i've described how to this.. (init.d ---> 01optimization) ;)
[Galaxy Ace II Android Development] ace2nutzer:
no problem.. now it was a bit useless .. because i've re-enabled all 5 options to make it working .. but maybe only 2 - 3 options is needed.. i tought i can reduce kernel size a bit more... hmm maybe i'll install link2sd and do itself some tests again ....

[MENTION=5715104]MrBlackCore[/MENTION] don't worry about much flashing .. i've flashed kernels on my Phone like 200 - 300 times.. and my Phone is still working :D
[Galaxy Ace II Android Development] MrBlackCore:
Im not worried its just I didnt know cache was a problem when I flash 6-7 times in a row. :D
[Galaxy Ace II Android Development] snatch_bill:
11/3 works fine for me when it comes to moving apps to sd card.Battery consumption

Is ok ,same as previous builds.I have screen taring though( ws driver) and had to edit

01 optimizations file to restore lcd freq to 57 Hz.

Thanks for all your work ace!You really are a great developer!
[Galaxy Ace II Android Development] ace2nutzer:
hehe ;) no problem dude ... btw many thanks for your help and time ! :o

Now i'll create second partition on sdcard as ext4 and move some apps to sdcard with link2sd .. I'm right ??

I've never do this.. because i've repartitioning the eMMC and i've still 1GB free on /data !

yeah.. tearings is on both drivers .. but don't forget: org. Freq is 50Mhz ! We're using with Rox Builds and so on .. since July 2014 LCD freq @ 57Mhz .. . usually nothing can happen.. i think also that nothing can happen... but some users meant that can damage the LCD and this ends up with grey lines on the screen ... Till now we've only one user with broked LCD ... [MENTION=4881398]PolishVodka[/MENTION] ... but i think it has nothing to do with OC'ed LCD .. because LCD's are going also broken without OC ;)
[Galaxy Ace II Android Development] snatch_bill:
Really? I didn't know that!Should I go back to 50 Hz?

I prefer some stuttering compared to a damaged screen.
[Galaxy Ace II Android Development] ace2nutzer:
As i said... i think it's not really dangerous .. it's maybe same like overclocking CPU / GPU ... we all do that .. but i never heard about a broked Phone due to OC . Also i've google it all about OC on refresh rate auf LCD .. and there also nothing about damaged LCD founded.. what i've found: if the refresh rate is too high then u've simply blackscreen .. after going back to org. refresh rate or lower value, the screen is working again normally.

But what is fact? The higher the refresh rate, the higher is the performance but also more power consumption.

Therefore it's your own decision and risk to do what u want with your Phone.. nobody can say it will work for ever or it will damage next month :o:D

btw: that "tearings" <----- why we say always "tearings" ? It's just a vsync problem .. actually i'm trying to fix this.. then it'll work also with stock freq 50Mhz smooth .. but i can't promise that ... i'm just trying to fix that :)
[Galaxy Ace II Android Development] snatch_bill:
Thanks for the info ace!My phone works smoother

With 57 Hz overall.This is a great Rom and you

Managed to keep this phone alive and functional

Even if it is a 3 year old low end one!

Let's hope that cyanogenmod sources will be updated

to fix the only bug remaining.....web videos full screen

Only playback.
