The script will NOT touch the real sdcard ... so all files stays on place.

but it'll delete everything form /system /data and sdcard0 (internal one)

That's why u should do at first an cwm backup and additionally backing up all files from internal sd0 to your real sdcard.

When u're done, u can start the process, u don't need to do a fresh install ... if u did already configure the ROM ... so u can do a cwm backup ..... then repart, format, and restore the cwm backup ... and everything is like before!

Anyway, if u still (again) want a clean installation, then just skip the fat marked steps:

Hi, everyone.

Some days ago I installed the new ROM (23-03-17). Since that, neither system notifications nor vibration work. I checked all settings but I couldn't fixed it. Harware is ok (I'm sure) so I don't know what the problem is. Any suggestion?

Thanks ;)
[Galaxy Ace II Android Development] huynhtran38:
Sorry my english is not good!

I just want to find the ROM for my GT-I8160 phone. thank you!
[Galaxy Ace II Android Development] gepel:
For me the most annoying bug on this rom (after middle of summer) is the buggy support on google account (browser bookmarks, youtube url history, even and google sign in on pokemon go is not working) and is not a gapps fault (triple checked).
[Galaxy Ace II Android Development] ace2nutzer:
U know it guys, write at least the last one working build rom or kernel.

But first u need to find out if it's rom or kernel issue.

Also what about other users ?

Only one has this issue ?
[Galaxy Ace II Android Development] Kurajmo:
No need to apology.

I understand everything what you say.

Cause i understand almost everything what people say in English.

I'm not native speaker. I'm like you still learning English.

But back on topic.

Do everyone a favor. For next time try to read first post carefully with attention.

And one other thing.

Stock rom for your phone you can find on sammobile Site.

There is stock roms library, for almost every Samsung Android phone.

Anyway Greetings
[Galaxy Ace II Android Development] huynhtran38:
I have experienced from CM11. CM12, CM13, and CM14 but no ROMs are light and smooth. Do a friend on the forum introduced so I know this ROM but do not know how to run properly to ROM work stable!
[Galaxy Ace II Android Development] ace2nutzer:
Try to wipe data (unfortunately) .. i don't have that bug.

According to your previous posts u've the GT-I8160 model.

So it's "codina"

make sure your Baseband is from any 4.1.2 ROM's (Stock roms)

and if u later installed any custom ROM's ... this is no problem.

just follow this sections on first post:

CLEAN INSTALLATION - Will delete all your Apps + Settings !

do not flash GT-I8160P Support.

do not flash GT-I8160L Support.

U even do not need to flash kernel.

If u'll like this ROM, u can later repart the internal flash and install proper kernel...

but for now, and because u're not a power user, it's better to install only some essentials.

Other than that, perform all steps !
[Galaxy Ace II Android Development] Torpedroid:
I will do. Thanks.
[Galaxy Ace II Android Development] huynhtran38:
I am using the ROM cm-11-20170323-UNOFFICIAL-FULL-codina. The first time you see the taskbar battery capacity and the clock does not work.

and Ace2Nutzer Kernel Control 1.5 is not supported so I removed it!
[Galaxy Ace II Android Development] ace2nutzer:
@up

there is no bug with clock or battery symbols ... u've to configure it in Settings for your needs.

Kernel Control APP only work if u've gapps installed and u've purchaesed the app...

see here:

https://play.google.com/store/apps/details?id=com.ace2nutzer.settings.device&hl=en

PS: Actually the App simply FC if there is something wrong with the config of the Phone, i'm working on it to fix it.

But as long u've working Play Store, and u've license for the App, allright.
[Galaxy Ace II Android Development] vbarcaz:
Hi,

This app, PocketBook, FC when you open it directly,

u can also add "screenshot" button on Power Menu .. check Settings --> Buttons --> ON/OFF Button :)

Hi, are u on latest Build 20170323 ??

Couldn't u try to install this app on any CM11 Device ??
[Galaxy Ace II Android Development] stefanoscheda:
With latest rom/kernel, on the taskbar quick settings toggling the sound tile from ring to vibrate doesn't work, while viceversa does work.

On build 20161227 and corresponding kernel everything was ok.
[Galaxy Ace II Android Development] ace2nutzer:
Right now tested and works fine here.

But i've to say that i did a fresh installation for latest build ... now everything works much better, smoother and faster.

Try to reconfigure (so toggle it) the Sound Options on settings ... and same for quick settings ... where u can configure what the button should do: vibrate, ring and so on .. then test if it's ok.

This will fix (rewrite) broken config files.

If it'll still not work, try a fresh installation.
[Galaxy Ace II Android Development] vbarcaz:
Yes I am on Build 20170323, and yes tested on friend phone:

samsung sm-g5308w stock rom 4.4.4 and works perfect.

Thanks.
[Galaxy Ace II Android Development] ace2nutzer:
ok noted.
[Galaxy Ace II Android Development] stefanoscheda:
That's it. In quick settings Sound was configured with Ring checked; I unchecked and now toogling is ok. Thanks. :)

I flashed newest build.

Sometimes clock with data and time disappear.

I don't now why.

But i see this happen when I listen music from aimp, and browse net with opera Mini.

Next bug is sometimes aimp stop playing music itself. I must reboot phone to fix this.

Any help with this?

Newest build is faster than older. But those two bugs still happen to my Ace 2
[Galaxy Ace II Android Development] ace2nutzer:
Those aren't Bugs :)

Rater it sounds like that the Low-Memory-Killer is killing processes due of low RAM.

I've changed the Behavior of swap/zram .. now it's using 1/4 instead 1/3 of RAM ...

Second, the swappiness is reduced from 100 to 60 ... which was very aggressively before.

In other words: less zram, and less swapping ... so it'll actually only swap if it's really needed.

So, as long the LMK can kill processes, the System is nearly not swapping.

(so it's a good idea to keep zram enabled by default, because it'll rescue the system in a case of Out-Of-RAM.)

That's why it's faster ... less swapping.

I suggest to delete useless Apps, and replace Big apps with small apps, in order to reduce the RAM Usage.

If it's not enough, u can increase the zRam to 1/3 .. in /system/etc/init.d/01_zram

then save and reboot the system.
[Galaxy Ace II Android Development] Kurajmo:
Yeah I try this.

I know this device is old. And low ram compare to newest devices like lg k3 or l65 which I use too. But still live. Anyway thanks for help
[Galaxy Ace II Android Development] AkosPaha:
Hello Guys!

I flashed the latest build(2017-03-23).

The CPU frequency is 1200MHz and a GPU frequency is 650 MHz. Sometimes

I hang my phone and randomly restart your RAM is consumed. Indeed, older than the build I used these frequencies than CPU and GPU at and did not have to hang such a result.

How to fix problems?
[Galaxy Ace II Android Development] Chuck Maddog:
i flashed the latest build

after several days, my phone's screen got shaded

how can i fix this?
[Galaxy Ace II Android Development] ace2nutzer:
@up

what's your LCD Type?

Can u post a picture or screenshot?

Make sure the kernel is also from 23/03 and the installed kernel control APP is V.1.5

Also make sure u didn't UV the CPU or / GPU Voltage ... so it should be 0.0mV (Kernel defaults)

Then if it's still not stable u can try to wipe data of this App .. since CPU Voltages changed in latest build.
[Galaxy Ace II Android Development] andon0v:
is there difference between cwm_cm11_partitions_layout_sdcard_only and the old cwm_cm11_partitons_layout which i use and it was from like January?
[Galaxy Ace II Android Development] ace2nutzer:
In the new script i've reduced the size of /system by around 50MB .. and moved those 50MB to /data.

So it's not very mandatory to update this, if u've enough free space on /data. :)

thank you for your hard work, the google pics works fine with uc browser, but i didn't get the radio to work (maybe because i'm from Brazil). So let's get started with the dumb questions :v

Is there any chance to we get latest TWRP with your kernel?

Not a request, i already know that isn't possible to import/export contacts from sim card if you're using custom rom on i8160/l/p, but the question is if it's possible to make it work?

---------- Post added at 03:55 AM ---------- Previous post was at 03:42 AM ----------

oh, i forgot one question, should or shouldn't we use greenify with your rom for better battery life? can someone recommend email, file manager/compressor, browser and others light apps for better battery life?

I don't understand about new partition ? now i using Rom (20170202) partition 3 GB on data n SDCARD set to internal storage, how to make partition new partition the new Rom (20170323) same with My rom version now?
[Galaxy Ace II Android Development] lace_hvc:
I dont know if this is a known issue or even a resolved one:

I connected my ace 2 to my windows 7 64bit laptop to transfer the backup but the phone restarts every time when I click on 'turn on usb storage' (UMS). Its charging through the usb cable and showing 2 removable disks on my computer that I can not click though. PTP works. MTP works. I think in the past it was always set to MTP. Dont know why its UMS now. Never changed it.

Im still on an older ROM (20161122) and kernel (20161117) because I wanted to keep the internal sd card as system and data storage, so I can keep removing the external sd card any time I want to. I never repartitioned.

Can I update to most recent ROM and kernel without having to repartition? Is standard a2n.kernel.4.4.x_20170411_codina.p.l right for me and doesnt require repartition? I wanna use both sd cards, be able to remove external microsd and also use xposed.
[Galaxy Ace II Android Development] Dagalur:
Ace2Nutzer, someone made a flashable version of the XXXX baseband repair solution, it was hard to find because most of the links are dead now, could you please upload this?

Hello Guys!

The latest A2N Kernel Control App(1.6) compatible wih the Kernel 2017-03-23?
[Galaxy Ace II Android Development] ace2nutzer:
@up

Yes it is !

No, sorry.

I think yes, but so far nobody care that much to fix it up, since it's not an urgent issue.

It's probably not worth it to install an app for just having some more free ram or a little bit battery lifetime.

Personally i don't use such high-level Solutions in order to improve the ROM or Kernel.

A good ROM and Kernel simply don't need such apps that manipulates the behavior of the ROM/Kernel.

But u may want to install an app in order to block ads, also i recommend to check the whole settings of ROM + Apps and disable always the sending of anonymous data for debugging purposes.

Another tip: Set the sync interval for e-mail and Weather to 1 hour.

That's how i configure my Phone, and i never had unusual high battery draining.

The Stock one are already fine :)

ROM Default is Mass storage, if u need other method, just go to Settings --> Storage ---> and check the menu.

Yes u can :laugh:

Yes, all right ! but use for now 23/03/17 kernel, because latest one has memory leak.

uploaded to "misc"

u don't need to repart again.

Anyway, when u update, kernel or the same Android Version, u usually never need to wipe data.

Even not if u want to change the layout of your partitions ... read pls post #3.

revert kernel.
[Galaxy Ace II Android Development] msq2:
How can turn off the zram ?
[Galaxy Ace II Android Development] ace2nutzer:
temporarily for the current session or permanent?
[Galaxy Ace II Android Development] msq2:
Pernament
[Galaxy Ace II Android Development] ace2nutzer:
open file manager, then configure it as root, allow root, then go to: /system/etc/init.d

and set permission of the script: 01_zram to 644.

Or just delete this script.

in all cases, reboot the system.

Note that after an kernel update this File may exists again, so u've to modify again.

More Memory Management improvements

SLAB allocator: switched from SLUB to SLAB

Some Kernel Tweaks

Updated the whole VM Setup

Optimized swap/zRam behavior - the system will swap only if there is no other way

Updated Minfree Values for maximum multitasking - uses the whole RAM except the last 1 MB, needed for a stable system

Re-enabled CONFIG_ANDROID_LOW_MEMORY_KILLER - Fixes bad performance from previous Version :o

Decreased zRam size to 1/4 of RAM - only used to avoid an OOM :good:

Version information:

Please test this Build and report here how it goes compared to the Version of 23.03.2017. :)

------------------------------------------------------------------

:o

Yeah black screens during usage is for sure OOM .... and it's because newer kernels have less swap, in order to improve speed + battery lifetime.

Try latest kernel 14.04.2017 and let me know how it goes for you.

It's App itself issues or better say, it's not supported anymore on that old OG YT Version ... since Google changed things. So i can do nothing since i'm not the Dev of such Apps. Anyway u can try similar Apps.

The phone loses its reach when downloading larger files. Logcat attached.
[Galaxy Ace II Android Development] Kurajmo:
I say this before.

Sometimes my Ace 2 lose GSM signal when I download something from web.

It's random issue.

Happen to me when I use opera mini etc.

Changing sim card or upgrade rom won't help
[Galaxy Ace II Android Development] ace2nutzer:
Try with latest kernel 15. and wifi.

If it's only happen with 3G i can't do nothing ..

probably not an issue, but likely a loss of signal range or other reasons from network provider.

What's your phone model and which baseband are u using?
[Galaxy Ace II Android Development] msq2:
The problem occurs only when the file is pulled at high speed, even in the play store itself.

When I was downloading from slow servers, I did not have this problem, just as I had limited internet speed to 1-2mbps.

Maybe logcat will help solve this rather cumbersome problem.

---------- Post added at 01:27 AM ---------- Previous post was at 01:21 AM ----------

The problem always occurs with fast download with 3g, sim card and network works well.

Model: i8160 baseband XXMF1 (I tested a lot) and on every kernel version this problem occurs.

On stock rom problem does not occur
[Galaxy Ace II Android Development] ace2nutzer:
Latest baseband for 8160 is NF2.

You can download it from FTP Server.

http://www.xda.mister-freeze.eu/XDA-files/ace2nutzer/Stock_ROM

And what about stock rom with A2N Kernel ?
[Galaxy Ace II Android Development] dixee:
currently i'm back using your latest CM11 and using full A2N kernel control,

with last vanir get very lag when using waze.

to update latest baseband NF2, should I flashed stock rom first?

i checked at sammobile, latest baseband are OD3?

https://www.sammobile.com/firmwares/database/GT-I8262/
[Galaxy Ace II Android Development] shaqman89:
Actually, it is NF2, type should've been GT-I8160 rather than GT-I8262

https://www.sammobile.com/firmwares/database/GT-I8160/
[Galaxy Ace II Android Development] msq2:
I installed the latest NF2 and cleaned cm11, but the problem still occurs

If you have the opportunity to try to download a file with a capacity of 50-200 mb with 3 g and turn off the screen for a while while downloading and switching on.

I think the problem occurs in cm11, not in the kernel or baseband, because the problem occurs even after the kernel flashes.

Here you have a page with files to test the speed of the inernet
[Galaxy Ace II Android Development] ace2nutzer:
I need to know if it works with stock rom but with A2N kernel.

If it doesn't work, test with cm11 from developer Rox and report please the results.

Thanks.
[Galaxy Ace II Android Development] msq2:

Wait, before u test those things, try this on my cm11:

Open kernel control app and enable: sweep to wake wakelock in screen section and try to download the file u want !

Wakelock does not help.

The phone loses its reach and you have to reboot to get the signal back

Flashing stock rom with your A2N kernel and testing

Already after the tests. Stock rom with a2n kernel does not have this problem, 1.5gb file was downloaded without problem. I will probably just use it now, I need information on what system applications I can remove and what modifications in build.prop to make the system run a little faster and more stable.

With that to ask about it I should rather in another thread.
