Hello @jordirpz,

no way sorry. It's just the way how the license check system works. It's not possible to disable it for users where I'm sure they have a valid license.

But don't worry, new update for kernel and app with big improvements is on the way.

You will see that you will be able to use the phone with Google Play Services as well, having good performance and battery life.
[Galaxy Ace II Android Development] ace2nutzer:
R90 is up !!

Changelog is on post #3.

Enjoy guys !!
[Galaxy Ace II Android Development] louis-NT:
It looks amazing.

Just found my Ace 2 and wanna try this to upgrade it to 4.4.4. but after flashing a2n_kernel_gt-i8160_ODIN.tar, I could not get into CWM. Tried with adb command also but no luck. It always boot directly to normal start. Do you have any idea @ace2nutzer
[Galaxy Ace II Android Development] ace2nutzer:
so you flashed a2n_kernel_gt-i8160_ODIN.tar with ODIN successfully?

To boot to CWM you need to power off the phone and then hold "power + home + volume up" till you see the first Samsung logo then release.

What Android version is actually installed?
[Galaxy Ace II Android Development] louis-NT:
My bad, I realized my home button need a hard force to work.

Finished installing cm11 and waiting for the first boot, but its over 5min already .... still black (I sawGalaxy Ace II screen once)
[Galaxy Ace II Android Development] ace2nutzer:
IF

you are familiar with ADB, try this:

boot to CWM and connect phone with PC.

Run ADB:

adb shell
cd /ramdisk
nano pllddr_oc_freq

change value from "1100000" to "1000000"

exit and save (Strg + X) then say Yes (Y) and press ENTER to save.

ELSE

download latest a2n_kernel for 4.4.4

unpack, open file ramdisk/pllddr_oc_freq with any text editor if you use Linux OR if your use Windows, use any C++ text editor to edit the file.

Then just change value from "1100000" to "1000000"

save, exit and repack the kernel package without other modifications as zip package.

Note: only zip compression works.

END IF

Finally wipe dalvik-cache in CWM and reboot to the system.

If CWM ask for ROOT, just say NO.

After the Samsung logo disappear, you should see after 4 sec the cyanogenmod boot animation.

Please let me know if this works for you.
[Galaxy Ace II Android Development] louis-NT:
Thanks for the info.

I think I worked around it before seeing your comment.

Steps are:

Factory reset

Install every zip except gapp

Reboot and booom.

I saw an error message about incompatible when install gapp, will try other zip when have time.
[Galaxy Ace II Android Development] ace2nutzer:
OK, but make sure to perform all the required installations steps from first page or your phone will not work properly.

I've to assume that you didn't read it, because factory reset is mentioned in step 4. Also you need to format /system partition and internal/external sdcards.

For gapps there are two links, one from official website to get latest version and a link where you can download a known working package from my download site.
[Galaxy Ace II Android Development] louis-NT:
Everything worked fine until reboot, it will stuck at boot again.

Changing the value of pllddr_oc_freq did the job, AWESOME bro!

Hi, my Ace 2 is on 2.3.6. I'm a little stuck on the first step, do I flash 3 parted rom or single to update to 4.4.4?
[Galaxy Ace II Android Development] gepel:
Hello ACe2nutzer and to all. Recenly i had need to reuse my old trustry ace2 and durirng the usage i have found some nice bugs.. First the ace2 is on the latest rom and kernel and my gpu is the ws24001. The bugs are these ones, 1st when rotate the phone inside the camera and filemanager app the screen has distorted graphics, 2nd when using bluetooth headphones the streaming audio stops every 5-10 secs. I tried to flash an old kernel (0522) but i had the same bugs. Then i flash again a fresh install of rom and 0522 kernel and everyth was ok (rotate screen and bluetooth) but if i flash again latest kernel (0523) the phone starts to having the same bugs. The weird is that if i flash the 0522 kernel the bugs remains and fix only if i restore a full backup with a previous state of the phone ..

[Galaxy Ace II Android Development] ace2nutzer:
@gepel

I've released R96. Could you please check if all your reported issues are now fixed in R96? - Please re-download also CM11 and flash it. (it has updated build.prop) and therefore wiping dalvik-cache is required.
[Galaxy Ace II Android Development] gepel:
Unfortunately, the problem with broken graphics when rotate the screen remains. About audio streaming in Bluetooth I didn't test it ,yet.. Is it possible to upload an newer version from 0522?
[Galaxy Ace II Android Development] ace2nutzer:
Ohh yes! - forgot to test ...

Just edit your build.prop:

debug.hwui.render_dirty_regions=true
in
debug.hwui.render_dirty_regions=false

save and reboot.

That should be fixed now. I guess it was a memory management issue.

I didn't change the BT stuff for years now.

I can re-upload the CM11 package with the fixed build.prop flag.

CM11 is EOL for years.

Edit:

re-uploaded fixed CM11 and kernel for stock ROM. (4.4.4 kernels wasn't affected for this issue)
[Galaxy Ace II Android Development] gepel:
The screen rotate bug was fixed. A lot of thanks to you !!
[Galaxy Ace II Android Development] gamersfan:
Very smooth and stable rom for everyday use, thanks!
[Galaxy Ace II Android Development] misiu11:
Hello

I got Android 4.4.4 KitKat for years and recently I noticed that newer versions of Androids are available (phone used from time to time).

I tried to upgrade to Android from 5.0 to 9.0 but on every installation step there was a problem. Firstly with CWM then TWRP and after that kernel, ROM ( different errors) and GAPPS. After tries and all steps phone stucked on Samsung logo or "brick" moments. I went back to stock ROM after that.

Now on phone is android 4.1.2 and I have a problem with CWM recovery installation. I must have mixed something (tried different files).

What I've done: In recovery mode installed ROOT, than CWM and enter temporary CWM recovery (6.0.2.8) and then unfortuntely rebooted and from this moment I can't install temporary CWM anymore. I tried wipe cache and factory reset - no change. Now only ROOT and CWM zip files can install. Any other files get an error "E:signature verification failed".

Correct me if I am wrong but this is connected with Unlocking Bootloader - I don't have option nowhere and none method works (must be blocked). I read it is necessary to uprade TWRP as I remember but this part is away from me.

While CWM installation got information "replacing stock recovery with Clockwork recovery" and after that screen goes black (if I tap power or home button it restarts but when first tap up or down and then power/home then not restarts - like I was in menu). I stuck on this and lack of any ideas how to move on.

I appreciate to any help on installing CWM recovery.
[Galaxy Ace II Android Development] ace2nutzer:
Hello, I suggest to start from scratch with "Step 0" from post #1.

This will fix all the mess.

Good luck!
[Galaxy Ace II Android Development] misiu11:
Thanks for reply.

I did so (step 0), than installed CWM and a2n_kernel_gt-i8160_ODIN. I have CWM 6.0.5.0 and it's stable to this step so far. a2n_kernel is my safe point now to get back.

I'd like to install TWRP 3.1.1 now to get CM13 or Lineage OS 15.1 or 16 but when I install TWRP (via ODIN or zip) stucks on Samsung Logo. To install via zip file got info to install kernel r5.2 or up version so did this.

I disabled Toggle signature verification as I got problems with that earlier. I made backup system and wipe options.

Should I first install KitKat 4.4.4 CM11 maybe?

Can you provide me installation order?
[Galaxy Ace II Android Development] ace2nutzer:
You need to run all the steps for installing CM11. In addition, just because CM13 is bigger than CM11, it needs more space on /system partition. So you must increase system partition (re-partition) while you run the steps. You can also try to install first CM11 and then at the end increase system partition and then install TWRP and then proceed with the installation steps from the CM13 thread. You need to search this forum for proper re-partition scripts method for this Galaxy Ace 2 that was made by me and Chrono.... there are a lot. (If there are no links in the CM13 thread for this).

Btw: if you install the ODIN kernel, then you don't need to install the temp_cwm. But you still need to flash a2nkernel for 4.4.4 normal version.

Don't use the sdcard_only version.
[Galaxy Ace II Android Development] cturnercomplex:
Hi,

I want to use my old ace 2 as Webcam for supervising my 3d printer and plan to use IP Webcam from: https://ip-webcam.en.uptodown.com/android

However when I open the app it immediately crashes - any Idea what could be the issue? Everything else seems fine.

Or is there a similar app for streaming videos for ace 2?

Thanks,

Chris
[Galaxy Ace II Android Development] misiu11:
I installed CM11 and had CWM 6.0.5.1 (Philz Touch 6). Now I remember that I installed TWRP on this step. Tried to do now but after flash stuck on samsung logo again (3-4 times restarts [loop] and stuck). I returned to Philz(kernel 2.24.5 or newer). Tried to install CM13 but I got only this:

Installing...

finding update package

opening update package

installating update

E:installation aborted

press any key to continue.

nothing else, no error code or anything

Don't I need kernel for this ROM first?

I will try tommorow with ROM 15.1 and 16.

Edit: Ok. Installed the newest kernel and somewhow I'm in Twrp now despite that installation wasn't complete. How to come back to actual state (TWRP recovery) if phone stucks again or installation fails?
[Galaxy Ace II Android Development] ace2nutzer:
The CM11 ROM from this thread is likely buggy. Try with the CM11 from ChronoMonoChrome ... you can still use a2n kernel if you like it better.

Sorry, but I can't help you there.

This thread is only for CM11.

Please ask your question in the corresponding thread.

[Galaxy Ace II Android Development] Grindur:
thanks man, youre a legend
[Galaxy Ace II Android Development] Grindur:
yea i got a problem, after flashing everything (except for swypefix bc i cant find download link) it just black screen and nothing
[Galaxy Ace II Android Development] acrocosm:
This time I used stability tester. I run cpu and cpu/gpu test for roughly 31' each with the cpu @ 1200 and had no issues.

However, when i tried to run the scaling test it soft rebooted when trying to scale up from 1150 to 1200

I'm attaching the log. It might not be very clean
[Galaxy Ace II Android Development] VRDRBR:
the new test build runs really great here. I'm on 1100mhz and no problems so far.

everything super fast and smooth.

(codina, ext4)
[Galaxy Ace II Android Development] dv6661:
blackscreen bug still present on sd6 device, but not always, i'm running with 400-1200mhz

New Build is Up !!!

Changelog:

20150127:

Fixed Random reboots on OC over 1Ghz - STE-Ericsson - Source / Hardware Bug

Removed too High GPU Steps

Updated 01optimization File

Fixed instability on cpu_freq Scaling

Set Deepest Sleep State "4" by Default

Enabled Scheduler Powersavings "2" by default for more speed + less power consumption

Optimized RAM Management (more free RAM)

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

Nope, u need to set this higher current than 600mA in Nt-APP ... but don't forget: if u set lower current than 600mA .. and u've disabled the Current Control in NT-APP (unchecked) then next time by plug-in the cable, the Phone will charge with the old current.. and by disconnect and reconnect the cable the Phone will charge with the Default Current: 600mA ... to avoid this confusion i suggest to let Current controll always enabled and set an proper current... but here is also an specially case: 100 - 600mA will work then without re-enabled Current Control... but for 700 - 900mA it's needed to disable and enable Current Control in NT-APP ... otherwise that will charge with default 600mA :);)

FSTRIM is not Supported here ...

U should test Again with latest build here 0127 .. because i've fixed the instability over 1Ghz ;)

Nope... both completely removed.. because it works only with wakelock and in some cases the screen looses response ....

What did u mean with 31' ?? 31 Minutes ?? - To make sure that is very stable the max. CPU Freq.. u need to run the CPU / GPU Test for minimum 2 Hours .. but 4 - 5 Hours reccomended .. of course with plugged charger ... the heat is no Problem.
[Galaxy Ace II Android Development] acrocosm:
Well no need to run it that long. it seems my cpu is not as hight quality as some others. At 1200 it's unstable quite earlier.

Of course heat plays a major role in overclocking. And component quality means a variance in heat dispension/tolerance. And this in turn accounts for stability. Sure there are other variables in play but this is the major problem as it kicks in first
[Galaxy Ace II Android Development] ace2nutzer:
Okay.. but not on our Ace2 ... i've never faced Problems with the heat.. The Ace2 Hardware is very good.

Problems with the heat i've only faced with Desktop PC's ... (according to the stability)

btw: it looks like the latest build have very good battery lifetime.. i've only 1% consumption of Battery by playing 1 Hour Music @ screen off with the Loud-speaker ... Amazing !! :o:D:D:D

PS: I use the Stock Player: Apollo ;)
[Galaxy Ace II Android Development] seanmalto:
Yes blackscreen issue still present.

first, when go to cwm recovery, i often got black screen. I have to do (vol up+home+power) many times to go there.

2nd, when i've got some notifications from chatting app, or any apps, then i force my phone to sleep, blackscreen appear.

sound, BLN, etc still present, but the screen just black :(

is the problem still sd6 lcd screen? can you fix this bug [MENTION=5840412]ace2nutzer[/MENTION] ?

i use ext4 codina,

my freq just 400-1000

and just set the gpu setting at novathor same as your recomendation at the first page.

no undervoltng, etc.

thankyou :)
[Galaxy Ace II Android Development] Jaro89:
Thanks for reply about FSTRIM, ace2nutzer. I was asking, because this kernel http://xdaforums.com/showthread.php?t=2724947 has trim support, so i was thinking that maybe yours too. Anyway, f2fs is supposed to take care of trimming by itself, at least thats what i've read (i'm wondering why, in that case, my Motog G Lte with f2fs has trimming support).

New Build is Up !

Changelog:

20150127_p1:

1. Attempt to fix Blackscreen Bug

Optimized I/O Speed (read-write, read_ahead_kb)

Updated 01optimization File

Can u Guys especially with s6d drivers.. test this build if the Blackscreen is fixed ?? - Thanks!

Pls report also blackscreen issue even if u've it only 1x per day ... thanks !!

What about RAM Management ???
[Galaxy Ace II Android Development] bidug:
Hi, I've installed 27/01/2015 version (not p1) and :

-never had any blackscreen issue, with this build or previous ones

-It seems stable at 1200MHz so far (few hours :p) thanks a lot! (random reboot at 1250MHz after 2min idle)

-RAM management seems very good for me

Thanks again for your involvement! :)
[Galaxy Ace II Android Development] shaqman89:
I am also using the same version, and quite happy with it. Using 1250MHz, I got a random reboot too but only after hours (it could be around 8 hours), so I'd say it's quite stable. *grin*

No obvious black screen, just got it once when I was installing an app from play store (you told us to report even once, right? :p) , but I'm willing to say it works great.

And I'm also quite happy with RAM management. Haven't felt any symptoms of low ram even after a day of multitasking.

One thing I found similar is battery consumption. For me it was around 5%/hour,which is roughly the same from previous versions (can't remember which). I wonder how you'd manage the 1%/hour with playing music :D

Gonna try the p1 now :D

Overall, for me, this is a big improvement from previous versions. Great job [MENTION=5840412]ace2nutzer[/MENTION].
[Galaxy Ace II Android Development] ace2nutzer:
Thanks for good feedback!

But u Guys with no blackscreen issue have ws2401 driver or ??

I've also ws2401 and of course no blackscreen ... works very good.
[Galaxy Ace II Android Development] shaqman89:
Yeah you're right, mine is also ws2401.

Seems it's still s6d related.
[Galaxy Ace II Android Development] seanmalto:
I've tested p1, and I've s6d lcd driver off course.

When i set mali :

Mali Boost Delay: 0 (Kernel Default)

Mali up threshold: 128 (Kernel Default)

Mali down threshold: 16 (Kernel Default)

I've got black screen when i do somehing like this:

idk why, but when i set boost delay, up threshold, down threshold to default, black screen not present so far.

CWM recovery still the same, i often got blackscreen. And again, i have to (vol up + home + power) many times.

CPU freq : 400-1000

thankyou :)
[Galaxy Ace II Android Development] ace2nutzer:
How did u change these Settings ??

Can u pls test with installed p1 if u've anyway blackscreen issue in CWM and after waking up the device ??? Thanks !
[Galaxy Ace II Android Development] seanmalto:
You mean mali? i set this from novathor setting(back to normal maybe):

Mali Boost Delay: 500

Mali up threshold: 233

Mali down threshold: 64

the rest settings i follow your instruction at the first page.

Black screen issue when sleep-wake quikly didn't present so far with this setting :)

yes i use p1 right now, at cwm recovery i still have black screen(often)

edit :

i also disabled auto boost GPU and GPU fullspeed.
[Galaxy Ace II Android Development] ace2nutzer:
Are'u really sure ?? Can u check pls what u see in: /sys/kernel/mali/mali_boost_delay
[Galaxy Ace II Android Development] seanmalto:
Hmm, after i check . It set to "0" :confused: :confused:

Now i know that it set to be like this at /sys/kernel/mali/ :) :

Mali Boost Delay: 0 (Kernel Default)

Mali up threshold: 128 (Kernel Default)

Mali down threshold: 16 (Kernel Default)

i'm sure that blackscreen when sleep-wake quickly doesn't present until now.

So what happen exactly?

maybe disable auto boost gpu and gpu fullspeed?
[Galaxy Ace II Android Development] ace2nutzer:
All these Settings incl. Mali boost on/off and gpu fullspeed and all GPU Clocks and all GPU / CPU Voltages aren't working by NT-APP .. that's why i was just wondering .. because it change nothing... best Values are already by Kernel default (optimized by me)

I wrote this settings in #3 post for older builds.. but in newer builds u don't need to change things in NT-APP ...

But anyway Black screen still present u say... i'll make new build ...
[Galaxy Ace II Android Development] seanmalto:
Okay i understand now :)

yes blackscreen at cwm recovery,

and maybe i just get some luck to didn't get any blackscreen when sleep-wake quickly :)

will report later if this happen again.

thanks for your great work :)
[Galaxy Ace II Android Development] ace2nutzer:
Well, pls tell me immediately when u've Blackscreen after waking up the device, tell me also how long the blackscreen appears in seconds... i'll make then directly a new build.... ;)
[Galaxy Ace II Android Development] miryn:
Couuuld aaanybody make that kernel for 4.3 ??
[Galaxy Ace II Android Development] soko3:
i don't know my screen driver. can anyone tell me how to check it?
[Galaxy Ace II Android Development] shaqman89:
Check inside folder sys/devices

There should be either ws2401 or sd6
[Galaxy Ace II Android Development] bidug:
Yeah, ws2401 :)
[Galaxy Ace II Android Development] DusBekas:
So far, the latest version (non p1) is the most stable version for me. CPU running @1GHz, had no issue :good:
[Galaxy Ace II Android Development] MrBlackCore:
same here. For the first time since forever the phone is stable at 1200mhz . No bugs so far.
[Galaxy Ace II Android Development] psidco:
What is blackscreen isue? Is there delay between we press power button to unlock the device? If yes on latest build with p version still exist,but i can go to cwm normally,stable as rock at 1200 ,better multitask and more battery drain i think(broken battery here :D ) ,thanks sir,great work :thumbup:
[Galaxy Ace II Android Development] galaxypep:
