[Galaxy Ace II Android Development] giginski:
ok ppl could U help me pls with gapps, as Ace said i downloaded rom from 18. , then pico gapps. When i intalled rom and try to instal picogapps i got abort. "It showed me Incompatible gapps currently installed. PA GApps can only be intalled on top of existing intallation of PA GAppa. You must wipe your system partition before installing any PA GApps package." Just tell me what im doing wrong? As i remmamber i can only intall larger package ~90mb
[Galaxy Ace II Android Development] Vexylle:
instal the universal pico gapps
[Galaxy Ace II Android Development] giginski:
i have pagaaps modular pico(uni) so i think its universal, but i think i found solution, i had to manully format system in recovery then i could intall gaapps, now i have to check it on my phone.
[Galaxy Ace II Android Development] ace2nutzer:
yes format system is always needed before updating gapps

broken english

Yesterday i had to go back to 2.3.6 for a moment.. Then ofc, i installed 4.1.2.

And i realized.. that i haven't seen that pure clean 2D smoothness for a loooong time.. I tried latests ace2nutzer's and Chrono's kernels on a few roms (incuding clean sh*tty CM11).. and i just can't believe, that soo many people (i think with WS driver, like me), just FORGOT, what it's like to see real 2D smoothness, and see no problem.. I thought maybe i was doing something wrong, I was trying all different kernels settings (lcd freqs, vsync, govs, inits blahblah) I even changed the 4.1.2 from NB1 to MG2, to make sure, that it wasn't fault of the 4.1.2 version and just wasted 2 days.. WTF?

Btw. Why i must add a sleep 90 init, to make some changes in minfree, VMs, etc.? On standard kernels its working all the time without sleepers:confused:

One more question.. If somebody can explain, why games like Real Racing 3 or NFS Most Wanted, work on standard 4.1.2- perfect smooth and fast, but on 4.4 with ace2nutzer's kernel or other 4.+ with Chrono's, it's working two times worse, even with hard CPU/GPU, ddr, chujumuju, OC?

Games working perfect with kernels without OC.

And last thing:

[MENTION=5840412]ace2nutzer[/MENTION] ; [MENTION=5695278]ChronoMonochrome[/MENTION]

What is yours lcd driver?
[Galaxy Ace II Android Development] MacOneil:
kernel

Is this kernel support otg ? because i would like to buy a USB that can use on mobile phone but it needs OTG support on mobile .
[Galaxy Ace II Android Development] shaqman89:
AFAIK, our phone doesn't have all the necessary hardware for OTG, so there is no way the kernel could activate this feature.
[Galaxy Ace II Android Development] ChronoMonochrome:
Have no clue. I never played mentioned games on ace2. However, for me PPSSPP runs a way better than without hard OC.

WS2401.
[Galaxy Ace II Android Development] ace2nutzer:
For me too, zero problems with my latest kernel.. with interactive and LCD 57Mhz is everything smooth.

sleep 90 command is needed to prevent the kernel / ROM to override your script....

I've also WS2401 ;)
[Galaxy Ace II Android Development] miryn:
Hmm. May I know, how do you exactly test 2D? What game or what app..

And about overriding commands.. More what i meant was Why is this happening only on your (and chrono's) kernels?
[Galaxy Ace II Android Development] ChronoMonochrome:
You'd better to ask is there any custom ROM, that itself doesn't override default minfree etc. That's why sleep command is needed.
[Galaxy Ace II Android Development] miryn:
oO

I'm now on Carbon 4.4.. i never had to add sleep commands on standard or PolishVodka's kernels. The same was on Liquid 4.3 and Slim 4.3.
[Galaxy Ace II Android Development] xo.en:
Oo? What? Can you elaborate? It may be important. I think we both are using similar scripts and solutions( i mean Miryn and me), and he has ws, while my device has s6d, we are experiencing totally different 2d performance. If i am right, it happens since first 4.3 roms.
[Galaxy Ace II Android Development] ace2nutzer:
That doesn't mean that sleep command isn't there... for example with my CM11 from 18/11 u don't need to use sleep command because it's already programmed in the ROM itself ... /system/bin/sysinit ;) Also it's possible that a sleep command is in ramdisk... then u'll also don't see this ;)
[Galaxy Ace II Android Development] miryn:
[MENTION=5840412]ace2nutzer[/MENTION]

Please.. ;)

If there was any sleep 90 command even in sysinit in Liq 4.3, Slim 4.3 or Carbon 4.4, I wouldn't wrote about this hole overwritting problem...

ALSO,

like i already said

, problem occurs only on yours kernels.
[Galaxy Ace II Android Development] ChronoMonochrome:
On every CM I used, I had to use sleep command to override some ROM defaults. I'm also had been using Carbon some time, but I don't remember, whether sleep command was needed or not. Although minfree values are written in ramdisk, I also remember that something else was overriding it, especially on CM11. Right now I'm on cm12, and it seems that simple changing those values in ramdisk is working, although on first its build I had to use "chmod 444" on LMK sysfs. It's definetely has something to do with ramdisk, though I didn't mess with it since sleep command is always working.
[Galaxy Ace II Android Development] ace2nutzer:
yes ! I've also writed custom minfree values directly in ramdisk and it works.

check: /device_tunables.rc ;)

I think that thing with init.d scripts depends simply on wich time the ramdisk will execute the "run-parts" ---> init.d scripts ... this is maybe different from rom to rom and from kernel to kernel.. so there is nothing to fix.. just use sleep command in the first script example ---> 00aa_blabla ... and u're done. At the end there is no difference ... (same result)

Therefore one more time:

only if needed: use "sleep 90" and check after reboot if the values from your script are applyed successful on sysfs ... till now sleep 90 was always enough. :cowboy:

Just to remember this:

this kernel is actually only "fully working" with my modded CM11 from 18/11 ... if somebody is using this kernel with other ROMs, so pls don't spam the thread over unsupported roms and bugs. :cool:
[Galaxy Ace II Android Development] miryn:
Ok.. I will no more discuss about inits, i see it's pretty pointless.

But one thing once again.. May i know how do ya test 2D?
[Galaxy Ace II Android Development] acrocosm:
[MENTION=5571055]miryn[/MENTION] man I feel ya.

And thats not the only issues. Battery life has not been on par with stock so far, not for a single moment. And there's always the streaming video issue...

But all this is forgotten. There are no bugs, all is good

Sometimes I really wonder why I dont go back...
[Galaxy Ace II Android Development] gepel:
Regarding the bug of missing icons(only is apps moved to SD) in home page with trebuchet i have to say that the problems does not exist with nova. So i deleted trebuchet and now im using nova without the above problem.
[MENTION=1823981]acen[/MENTION]utzer Can you provide me a guide (step by step) about how can i change the freq of my lcd display to 57hz and how can i check my lcd driver.

A big thanks to Acenutzer for his great work !!
[Galaxy Ace II Android Development] dixee:
hi, does anyone know how to solved Stk.apk disappeared in app drawer? i need this apk working on my phone. as far as i know from several kitkat custom rom, no working stk yet in my ace 2, also with cm11 ace2nutzer+his kernel too

i try some method out there but nothing worked for me
[Galaxy Ace II Android Development] ace2nutzer:
Open the FileManager and go to: /system/etc/init.d/01optimization and read the content .. it's usually self-explained ..

Remove the "#" before the echo 1 command .. then save and reboot, at this way it's permanently till u flash other ROM or kernel or also if u flash an update of this kernel... that means, after an update from me, u need to remove the "#" again ... :)

Check LCD Freq: /sys/kernel/mcde/lcd_clk

Check LCD Driver: /sys/devices/pri_lcd_XXXXX
[Galaxy Ace II Android Development] ace2nutzer:
remane it to: Stk.bak then it's freezed .. with .apk it should work normally ... ;)
[Galaxy Ace II Android Development] miryn:
[MENTION=5840412]ace2nutzer[/MENTION]

How do you test 2D?
[Galaxy Ace II Android Development] dixee:
i don't understand , you mean that just rename it to get this file showed up in my app drawer menu? :D

i mean that Stk.apk file is there in the rom like your CM11 rom, also Rox and other kitkat rom, but this Sim Toolkit application not showing in my app drawer menu. this is CM bug or what? :confused:
[Galaxy Ace II Android Development] ace2nutzer:
Check the Filename with FileManager .. maybe it's freezed ---> stk.bak .. then u should rename it @ stk.apk to make it working.

To make it working u need a simcard + onlinemode .. no airplane mode .

@ 2D

i test 2D on multiple things like: scrolling home menus... (Nova launcher) scrolling: all apps with cube effekt .., CM Settings scrolling ...

Whatzapp contact list scrolling .. and at the end a 2D Game: "Pou" with the in App Game: "Sky Jump"

That simple 2D Game works only smooth with Stock GB, and now with CM 11 + my kernel + LCD @ 57Mhz for the moment...

With Stock JB that Game is really laggy, it makes no fun to play it.
[Galaxy Ace II Android Development] dixee:
i checked with root browser / link2sd the filename still Stk.apk, but this app not showing in app drawer. also with no airplane mode. before that i think Stk.apk has a conflict with other apk, because sometimes Stk.apk showed up in my app drawer, but when i restarted the phone Stk.apk is missing again from app drawer. but i'm not sure this was a conflict with other apk.

are this app showed up in your app drawer in your Ace II ?can u give me your screenshot?for the moment, i return to stock JB 4.1.2 :crying: because i need Sim Toolkit to access menu from my operator. i have been use your cm11 rom for a long time, also with your kernel.

or can you give me the correct procedure/setting to install your cm11 rom again, to get this Stk.apk displayed in my app drawer?

cheers:D
[Galaxy Ace II Android Development] gothicVI:
@up: actually sim toolkit app - as all other system apps - never showed up in my app drawer. Neither on cm11 nor on cm12
[Galaxy Ace II Android Development] ace2nutzer:
[MENTION=5587485]dixee[/MENTION]

i really don't know.. for me i've freezed that stock app, because i don't need this.. but i can unfreeze to see if the app appear.. i''ll tell u later here..

I'll edit this post....

EDIT: After renaming from Stk.bak @ Stk.apk nothing happen .. but after a reboot with 2G Signal, the App "SIM-Toolkit" appears !
[Galaxy Ace II Android Development] shaqman89:
I second this. It didn't showed up in mine too.
[Galaxy Ace II Android Development] ace2nutzer:

[MENTION=5840412]ace2nutzer[/MENTION], on 0403 version apps on SD doesn't appear.. :(
[Galaxy Ace II Android Development] :
And when will this version of the RAM ?
[Galaxy Ace II Android Development] ace2nutzer:
when i've time :)

@ sd apps.. is the problem by moving apps with link2sd or from CM settings ??
[Galaxy Ace II Android Development] miryn:
The biggest problem with 2D is in "horizontal-going" games like impossible game or flappy bird..

Believe me, 2D can be a lot better and it doesn't depend only on lcd freq.. If you test 2D only with vertical scrollings and games (like pou's sky jump -.-), etc. it's only halfway to the destination.
[Galaxy Ace II Android Development] ace2nutzer:
ok, is it also laggy if u set CPU min.max @ 1Ghz and LCD @ 57 Mhz ??
[Galaxy Ace II Android Development] miryn:
I think i've tried all configurations like that.. Yes it is.

CPU, GPU OC, ddr OC, UV, OV, different govs, VMs, Different Mali values, no zram, no ksm.

Maybe it's little hard to perceive, but if somebody saw how it works on stock (yep, 4.1.2, games which i mentioned and maany others), the difference will be huge. I'm not a gamer! But if something can be better, just don't say it is perfect.

Btw. On latest kernel there's no problem with apps (nova launcher).
[Galaxy Ace II Android Development] ChronoMonochrome:
60 fps in flappy birds with zero graphical artefacts or laggs with mcdeclk 57 MHz(well, with 50 MHz image messes a bit), GPU 300/400 MHz. How can it be better?
[Galaxy Ace II Android Development] fluffi444:
Same here... But 60Mhz (because of DDR 975) - tested this seconds ago just out of curiosity...
[Galaxy Ace II Android Development] Bito21:
[MENTION=5840412]ace2nutzer[/MENTION], apps that was already on SD card diseapeard on the latest buid.
[Galaxy Ace II Android Development] miryn:
Me to: 59-61 fps.

Fps doesn't matter here, there'll be ~60fps in spite of little v-sync problem.

Edit: Ok let's end this hole 2D thing maybe.. You'll never uderstand what i'm talking about if you haven't check it out on stock.

Here, 2D maybe is smooth, but on stock- it flows (in games, not in browser in turn) .
[Galaxy Ace II Android Development] ace2nutzer:
Yes i know that.. but i need to know if u've moved that apps with link2sd or just over CM settings .. this is not the same :o

@ 2D this is very weird that it's more smooth on Stock JB .. because that JB Version has so many bugs.. and screen tearings because of vsync prob + 50Mhz of LCD ...

The only perfect ROM was Stock GB .. everything smooth.. but too much old to use it for today ... many apps will not work on 2.3.6. And Stock JB is also crappy because as i said of too much bugs, memery leaks, bad ram management and and and ...

Best ROM is still CM 11 + one of Custom Kernels here ... and of course a working brain :p
[Galaxy Ace II Android Development] Bito21:
[MENTION=5840412]ace2nutzer[/MENTION], the problem is on the CM settings.

sorry for not explained very well.
[Galaxy Ace II Android Development] MrBlackCore:
Not movable with link2sd. Second partition not found error
[Galaxy Ace II Android Development] snyfear:
Hi Guys,

I need some advices regarding repartitioning. I followed the post on page 1 and everything was right but know I want to reduce again the SD size from 500Mb to 10mb.

I found the script "CWM_ReParted_SY650_CA150_DA3043_SD10" on dev-host but don't know how it works.

Should I just flash it from CWM and all my other partitions data will be kept safe or should I extract the new partitions size to enter then manually?

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

do cwm backup and flash the zip.. after that, restore the backup.

u've probably again forgotten to wipe cache :D

For me link2sd works... right now tested.. but a moved app from provious build with cm settings is gone after updating to the 0403 build. :o

Rght now i'm fixing this bug, so u can expect in approx. 2 Hours new build with working SD Apps.
[Galaxy Ace II Android Development] snyfear:
Hi ace2nutzer, as usual thanks for your quickness and efficiency.

However I am facing problem when restoring backup while formating /data :

Formatting /data...
E:format_volume: make_extf4fs failed on /dev/block/mmcblk0p5
Error formatting /data!

Should I reboot between flashing the script and restoring data?

Is there a brick risk if I reboot now or should I before fix the issue while CWM is still accessible.

EDIT: after several format, reboot, reflash script and restore everything is back to normal with partitions desired sizes. Thanks

Thanks ace2nutzer..
[Galaxy Ace II Android Development] hector_yo:
I'm now on 0405, and I have the same issue =(, I tried to re-apply repart.zip, reformat system, data and cache to f2fs, and sdcard0 to vfat, then reinstall kernel cm11 and gapps (also wiping cache), and swap memories on NTsettings, so the installation should be fresh, but it didn't work. I'm still unable to move apps to SDcard. If I try to move an app smaller tan 10mb, I can, but it moves to internal sdcard, even if swapped memories or not...

Kernel is working very well for me (except for this), can anyone help me?

PD sorry if my english is too bad...
[Galaxy Ace II Android Development] ace2nutzer:
Hmm, weird.. what's your Filesystem of your 16GB sdcard ?
[Galaxy Ace II Android Development] hector_yo:
Fat32
[Galaxy Ace II Android Development] ace2nutzer:
Hmm weird.. i've also fat32 and no probs...

But that u can't move some apps from cm settings to sdcard is normal.. that works only for some apps...

The Problem is also that after repart. internal sdcard is only 10MB .. and some apps doesn't recognized that internal sdcard is now sdcard1 after swap storages ....

And.... If u like to move anyway apps to ext-sdcard .. then u should use "link2sd" and create a second partition on ext-sd with ext4 Filesystem.. And then it should work with link2sd .. and use always: "create a link" and choose all Options ... then OK .. it'll move so many data as possible to sdcard second partition !

For me tested and works.. first i've tried to move an specific app over cm settings, and don't worked.. then i tried with link2sd and worked. :)

But that u've error message by installing new app from play .. is very weird ... .. something is wrong with your Phone...
[Galaxy Ace II Android Development] hector_yo:
I already have LinkToSD ;) but the problem is that if I can't install apps, I can't move them...

To try something else, what should I do to make 1.5GB + 0.5Gb (or even to restore original partition table)? maybe doing this can allow me to install apps, and then I can move them to extSD
[Galaxy Ace II Android Development] snyfear:
If you want an internal SD partition of 500Mb you will find all repart instructions in the 3rd thread of this topic.
[Galaxy Ace II Android Development] letkogazowany:
i'm new here so helo everybody. unfortunatelly still got unlock black screen bug on sd6 device. after 1 day on 20150403 kernel it happened three times. Even if i try lock/unlock couple of times it doesn't help. i have to restard divice.

After wipes (data, cache, dalvik cache) and format /system i installed zips in order:

codina_kernel_cm11_20150403_ext4_ace2nutzer.zip is buggy .. use better: codina_kernel_cm11_20150405_ext4_ace2nutzer.zip
[Galaxy Ace II Android Development] yanokashi:
Hi Ace2Nutzer. I changed my kernel to yours and I'm surprised with the overall performance of the phone. It' really good. At the beggining I was scared because of 400MHz minimum frequency, but wrongly. Now I have your CM11 on all-f2fs with 400-1100 as a daily and it's really good :)

Anyway, I have 1 question. Why I have only 13k in Antutu?

400-1250 CPU, 700GPU, OV +25mV (on 0 I had "Antutu aplication browser was unexpectedly stopped) Woth the same set up woth Chrono I had about 17k in Antutu. I don't know why on your I have only 13 because overall performance is the same or better..
[Galaxy Ace II Android Development] ace2nutzer:
Hmm i don't know .. maybe [MENTION=5695278]ChronoMonochrome[/MENTION] can explain it better ? :D

btw: how do u change GPU Freq ? - Changing over NT-APP or Chrono App will not work. UV/OV is completely disabled on my Kernel.. at least with NT-APP is it disabled .. but still working over init.d scripts for some power users,, or if the default UV is not stable for someone .. but in generally the default UV is stable for 90 - 95% of all Users around the World :)

Therefore: Check this Points: freeze Chrono-App, and delete all init.d scrips except: 01optimization and 01gpu_oc.

Maybe u achieve 17k Points on Chrono-Kernel with DDR OC; other I/O Scheduler than SIOPlus; and maybe with Dynamic Fsync ??

The last 3 mentioned things are not present on my Kernel. Those features have BIG Performance Boost, but still not fully safe and stable and also too risky of Data/filesystem corruption.

btw2: I achieve 13400 Points with the Config in my Signature...
[Galaxy Ace II Android Development] fluffi444:
The biggest bang gives you Dynamic Fsync. Typically this gives you a jump from ~13000 to ~15000+.

Standard Dynamic Fsync is known to be a bit dangerous if the phone reboots or freezes (for some other reasons). That could lead to data loss.

But Chrono introduces dynamic fsync with implementation by faux123 since R2.20 - Don't know if this helps against this behaviour.
[Galaxy Ace II Android Development] ace2nutzer:
If some Users can confirm no data corruptions by FC App, and random reboot, then i'll try to implement this feature on this Kernel too :D;)
[Galaxy Ace II Android Development] shaqman89:
Well, I could confirm that for you :D

Haven't got any data corruptions by any FC or random reboot.

But I can't say whether I am an exception or not.
[Galaxy Ace II Android Development] Ave_Hornet:
You Are wrong dynamic fsync implemented in Chrono Kernel causes data coruption this is really anoy when u try to setup OV/UV all over again...
[Galaxy Ace II Android Development] yanokashi:
1. I set NT app as system app. You wrote that it doesn't work but when I started Antutu test, I got "unfortunately, app was unexpectedly stopped". When I set +25mV in NT Antutu finished test so that's kinda weird :D

2. If you achieve 13400, ok, now I'm sure that my codina works properly ;)

Yyy so how can I overclock GPU?

PS You and Chrono should make your kernel together - ChronoNutzer would be perfect kernel for codina :laugh:

But seriously, Nutzer's stability, smoothness and powersaving with Chrono's super tweaks would be welcome :)
[Galaxy Ace II Android Development] ace2nutzer:
Check: /system/etc/init.d/ i'm sure u've at least one script that write system:system for CPU/GPU SYSFS ( /sys/kernel/liveopp and /sys/kernel/mali/) .. if yes, u're running the Phone with unstable Voltages from NT-APP ...

First make sure that u've only these 2 scripts: 01optimization and 01gpu_oc .. in /system/etc/init. then open the script 01gpu_oc and remove one of the "#" to OC the GPU, then save and execute the script, or just reboot the Phone :)

ChronoNutzer .. lol that sounds weird :cyclops: :D - But Maybe a new Project like: "Ace2Nutzer-Chrono Remix" :o:D

btw: u can make it even more smooth if u open the File "01optimization" and enable "LCD Boost" (also by simply removing "#")

But if u've s6d LCD Driver, then it's possible that u've later the famous "Blackscreen Bug" .. if so, re-add the "#" before "echo 1 > ..." save, and reboot, the u've fixed that Bug by yourself ... And yes ! Then u're a developer :D:D;)
[Galaxy Ace II Android Development] hector_yo:
oops thx, I thought It was the same as repart.zip....

I did that and everything seems working fine, thanks to all of you :)

[Galaxy Ace II Android Development] Sylvinette:
Hi, I'm new here, as before as silent reader.

I'm planning to reinstall my os, first I downloaded "cm-11-20141118-UNOFFICIAL-codina_f2fs.zip" then "codina_kernel_cm11_20150405_f2fs_ace2nutzer.zip" and "pa_gapps-modular-pico(uni)-4.4.4-20150308-signed.zip".

This is my procedure: Re-flash stock JB -> CWM -> cm11 -> gapps -> kernel

I just want to know what is the difference about ext4 and f2fs? Which one has stability for daily use?
