In the NT-APP the help text says already some things ... So what u need to know ??

u maybe don't know how to use it ???

Quick explanation:

before u UV u shold check what is your stable max. CPU / GPU Freq ... like here below described but of course without UV... after that, u can continue:

for CPU:

undervolt always in one step (-12.5mV) and use the Phone for at least 2 minutes ... if no app will FC .. then u can UV one step more: -25mV .. and then test again for 2 minutes... and so on ... Then when u've found stable undervolting for cpu .. u can use the phone for at least 3 - 5 Days and then (if no random reboot) i suggest to add on your stable UV + 25mV (2 steps) to make it 100% stable even on extreme situations like high humidity and too low/high temperatures ;) In some rare situations it'S even possible that u need to overvolt a bit to have that stable result ... this is normal.. as i already said that cpu is by default already undervolted -50mV :)

for GPU:

undervolt always in one step (-12.5mV) and play an 3D game for at least 5 minutes ... if u don't see any weird things like artefacte.. image messes or even freezes or unusual laggs .. then u can UV one step more: -25mV .. and then test again for 5 minutes... and so on ... Then when u've found stable undervolting for gpu .. u can play an 3D Game for at least 30 - 60 minutes and then (if everything was ok) i suggest to add on your stable UV + 25mV (2 steps) to make it 100% stable even on extreme situations like high humidity and too low/high temperatures ;)

I've made clean install of latest CM11 + kernel and i got reboots. Can't pass the setup wizard. Of course factory reset whose made.
[Galaxy Ace II Android Development] bebolint98:
Try to reinstall the cm11 with wipe data factory reset,wipe cache and dalvik cache,format system and install the cm11.You setup the phone and after install the latest kernel.I have the same problem when do the same and after I try to enter the pin code to setup the phone the phone reboot always.After do that I write It's everithing works fine.
[Galaxy Ace II Android Development] pablo.see:
OK, thanks I will try Your way. Now Ace2 is lying around and it's only purpose is generating white noise for better sleep to my son hahaha. Now I own Xiaomi Redmi 2. Awesome phone for it's price. I wish ace2nutzer collaborate with zwilew on work for better CM11. zwilew now have sources for kernel.

Update #1

No go for Your method. I'll older CM11 version.

Update #2

Silly Me! RTFM! I didn't installed latest verison of novathor settings. Now it works fine.
[Galaxy Ace II Android Development] ace2nutzer:
Yeah that's right, latest kernel is only stable with latest NovaThor Settings app due to re-enabled permissions for CPU/GPU UV ... and because older NT-APP sets now wrong voltages for CPU/GPU, the phone reboots ;)
[Galaxy Ace II Android Development] zizoumadrid:
I've sold my ace2 in a few days ago and bought a new phone S2 i want to thank everyone who give something to keep this phone alive especially [MENTION=5695278]ChronoMonochrome[/MENTION] [MENTION=5840412]ace2nutzer[/MENTION]

We really passing a good time with that phone i feel like we are one family love you all peace bye :crying:
[Galaxy Ace II Android Development] ace2nutzer:
Very sad to see that soo many users are left this Phone .. now when the kernels are running really good and now when i finally have updated NT-APP..... :( hmm...

Maybe i'll try to build an final CM11 snapshot with EXTREME Code Optimizations based on this kernel if [MENTION=5695278]ChronoMonochrome[/MENTION] will help me :o

btw: if this post reaches at least 50 "thanks", then i promise i'll do this definitely ;)
[Galaxy Ace II Android Development] thode1226:
If I want to update NT-App, do I need to flash v1.6 before v1.6.1 [MENTION=5840412]ace2nutzer[/MENTION] ?

Still use Ace 2 bcz you've improved its kernel, hope to see your awsome last work :o
[Galaxy Ace II Android Development] ace2nutzer:
Nope.. just flash latest NT-APP + latest kernel at the same time in cwm ... ;)
[Galaxy Ace II Android Development] ChronoMonochrome:
Isn't it would be better to focus on another things rather than extreme code optimizations? Everytime I applied those optimizations I faced weird issues. Maybe just bad luck, but who knows :) From my experience: performance gain from those optimizations isn't noticeable neither in userpace nor in benchmark. You only can obtain this performance gain by compiling and running twice a special benchmark(compiled with and without optimizations). I don't want to say that these optimizations are useless, but they're not giving that much performance gain as it may seem.

If you need any help, just PM me.

you are serious :D
[Galaxy Ace II Android Development] MrBlackCore:


Its not like I'm abandoning my ace2 but whatever you and chrono do you just can't go over the hardware limit. :) I love that phone but 700 something ram is not enough anymore. And the fact that I cant use your kernel with cm12 makes me switch to another phone even more.
[Galaxy Ace II Android Development] ace2nutzer:
Yes this is of course possible, so it was not bad luck ;) We can't use all optimizations flags ... there are some flags that breaks ISO Rules .. and some are experimental ----> they can produce broken Code. ... So we've to sort out that bad flags ....That's all :)

I never trusted benchmarks for such thing as we know it's software optimizations and not hardware OC. I just count on real usage "feeling" .. and yes there is BIG difference between optimized code and standard code ... the much easier way is to compare this latest ROM here (low optimized) with your CM11 Build: 20150505 (high optimized) and check scrolling on "Settings" ... :) On your Build it's much more smoother ;) And this even without EXTREME Code Optimizations and without faster ARM mode instead slower THUMB-Mode ... ;)

Thank u very much, we all really appreciated your generous helps !! :)

:D I just need some motivations ... nothing more :)

Really ??? hmm for userspace there is 628MB real RAM + 300MB of compressed RAM = approx 900MB - 1GB RAM .. more is not possible.. (at least without reducing performance at all)

btw: why u need CM12 ?? i think CM12 need even more RAM !! - But if u want to give a try .. u can flash an good CM12 Build and then flash latest CM12 kernel by [MENTION=4881398]PolishVodka[/MENTION] ... he compiled this kernels from my sources ;)

Check some posts before here ... he did post the download link ..... :)
[Galaxy Ace II Android Development] judas1977:
Yes, it's normal that phone is extremely 'well coded' by devs at its final stage. And ace 2 has luck to have great devs: Rox, you, Chrono. With a precious help of some other (bagnz0r, criminal, etc.)

With fabulous contribution of PolishVodka of course...

And guys, who give aosp (4.4 and now 5.1) and other ROMs.

I think i forgot about someone..

Yes, i think both ace 2 and ace2 users had much luck. I don't know a low budget phone with such ROMs base and support (maybe zte blade before)

Blackmailer :)

Great work!

Kernel 6 aug 2015 is the best so far.the device is smoother than ever!!! I use mg2 ,rom cm11 18/11/2014.i havent update nt-app i use 1.5 only for swap sd no problems at all.so plans for new phone are canceled again.you guys kyrillos13, rox, ace2nutzer,chronomonochrome,polishvodka made miracles with this device! U should work as developers in big companies like apple samsung sony!but these companies are in deep sleep they provide poor sw with useless apps+ lags+ bugs and after 2 years the say buy a new phone.i think all u guys should agree wich will be your new phone maby a value for money china phone with good specs,co-operate and show the world that u dont need to buy new phone for many many years!!! Respect to all devs...
[Galaxy Ace II Android Development] Jerghal:
Boot loop problem

Up until the kernel 20150806 it works fine but kernel 20150807 and 20150810 throw the phone in a boot loop even when it's not connected to USB or a charger. After like 10 seconds on the lock screen it freezes and reboots.

So I reverted back to 0806 for now but that one does not have the Stagefright fix.

---------- Post added at 11:00 PM ---------- Previous post was at 10:49 PM ----------

Ok, posted a bit quick. I see in previous posts it has something to do with NT-APP settings. It's a bit unclear how that works but I will read into it some more before I ask another stupid question ;)
[Galaxy Ace II Android Development] ace2nutzer:
For what i write Changelogs + Notes ??

If i write:

then i didn't write this just for fun ;)

And it has nothing to do with StageFright ...it is separated and u can download this patch in dev-host ... just flash all 3 things in an row in cwm: kernel, NT-APP, and patch 1 (the order doesn't matter here)

Testing...
[Galaxy Ace II Android Development] heldix:
After testing one day: Seems to be noticeable faster and smoother. I experienced no bugs yet! Good work mate!
[Galaxy Ace II Android Development] arroyo:
36 Thanks collected. Do I really need to create 14 spare XDA accounts like: arroyo_one, arroyo_two, arroyo_trzy, arroyo_four, ...?

About today kernel. It is smoother than previous, faster but looks like it is draining a bit more battery. Maybe it is a placebo, need to test it longer.
[Galaxy Ace II Android Development] Bito21:
Hello,

After a day of testing the new kernel I have the same opinion of [MENTION=1638660]arroyo[/MENTION].

The phone feels more smoother and faster, even in battery saver profile with max CPU@600Mhz, but seem that the battery drains a lit more faster.
[Galaxy Ace II Android Development] HostisSupremus:
I've just installed the latest update yesterday - whole combo from ace2nutzer files (ROM+Gapps+Patch+NT+kernel) and I'm gad to say it runs flawlessly and performance is noticeably better than it was before (I'll be 100% after about a week but nothing seems to foreshadow any issues).

Two nice things about the ROM listed in changelog are patch against Stagefright and my favourite launcher as default (Nova Launcher).

Thanx, mate :)
[Galaxy Ace II Android Development] alessandroarzilli:
Compatibility?

One question: is this kernel compatible with the ROM

4.4.4 J-TEAM AOSP - Android Open Source Project KTU84P FINAL ?

Thanks in advance!
[Galaxy Ace II Android Development] ace2nutzer:
it works with every 4.4.x rom.

the only important thing is to use latest NovaThor App ---> 1.6.1 (on dev-host) and to delete Chrono kernel settings apk and init.d scripts, then it should work stable.
[Galaxy Ace II Android Development] ace2nutzer:
New Kernel is Up !!

Changelog:

if u experience slow charging, then set in NT-APP 400mA charging current and then back again to 700mA for re init.
[Galaxy Ace II Android Development] alessandroarzilli:
Ok. What should I do to delete chrono kernel settings apk and init.d scripts?

Are They all being deleted automatically?

Thanks
[Galaxy Ace II Android Development] bebolint98:
If you have installed the ck setting apk delete manually with the file manager from system/app and also with file manager delete all init.d script from system/etc/init.d.After you can flash the kernel from recovery
[Galaxy Ace II Android Development] Fabbb2:
Thank you for this kernel.

I did the big update yesterday (i have the P model, so i flashed with odin to get more ram like you told me) and flashed the last rom and kernel. Everything is working great up to now. So big thank for that !

I'd like to test OTG. I have the adapters for micro sd but nothing happens. I just checked the power option in NT. Have i to do something else ?
[Galaxy Ace II Android Development] MrBlackCore:
OTG not working for me neither.
[Galaxy Ace II Android Development] ace2nutzer:
OTG is actually in development by me .. it's just enabled in kernel .. but there's needed to make some other changes in kernel and ROM to make it maybe fully working.. but i can't promise that it'll work at all.

If at the end it'll not work, then i'll disable all OTG options in kernel in order to reduce kernel size and free some RAM ;)

btw: right now i'm starting with CM11 building (setup) ;)
[Galaxy Ace II Android Development] heldix:
Hmm with the latest two kernels i got problems with GPS again. I use STRAVA everyday two times to record my bicycling and my running tracks. Worked flawlessly for weeks with the 0807 build but with the new ones i had to reboot the phone several times now. The same with google maps. I heavily use it for navigation while driving car. Even with the 0821 some times the GPS just doesnt track my position or doenst move. Back to the 0807 it works again for days.

Maybe its got to do with the more RAM change? Chrono mentioned sth earlier that that might produce problems with buildin features even if u dont see them directly.
[Galaxy Ace II Android Development] TheLiquidGuy:
Is this kernel better than Chrono's for TC's CM11? Does this kernel makes the ROM faster than with chrono's kernel?
[Galaxy Ace II Android Development] shaqman89:
Try it yourself. I could say that both has it's own virtues, so pick whichever suits you best.

AFAIK, major difference in both is that Ace's kernel focus more on simplicity and performance, while Chrono's focuses more on battery life and options.
[Galaxy Ace II Android Development] TheLiquidGuy:
Could someone give a link to Patch and NT, please?

EDIT: I found the NovaThorSettings 1.6.1

patch1_for_cm11_20150714.zip will this work on team canjica's CM11 build cm-11-20141109-UNOFFICIAL-codina ?
[Galaxy Ace II Android Development] greeceeeee:
Do you have any problem with flashlight? For me it works one time on camera or in torch button and then it works only after a little time I leave it on screen off and enable the phone again taking only one photo with flash the it does not work or pressing the torch button one time,the second time I press it doesn't work...
[Galaxy Ace II Android Development] matthias1976:
I got such problems in chrono kernel and rom.

I think thats no gps related Problem. Gps works in every app the whole time. But when i track some path with google my tracks or osmand after some time i dont track anymore ir path is uncoplete tracked.

Maybe some gps track related things kicked outa ram !?

I got whatsapp and threema nitification problem too.

But its in chronokernel not ace'S kernel but i read some guys got Problem with aces's kernel too.

[Galaxy Ace II Android Development] Dr360r:
Went from CM11 TC 08/07 /2014 to the 07/14/2015 ROM and finally got rid of the GMS crash that required me to erase Services cache every time i rebooted my 8160. The crash kept happening with the new rom but all i had to do to solve it was a factory reset in the CWM (i just dirty flashed beforehand cleaning only cache and Dalvik) followed by a flash of the listed 06/17 gapps. After flashing the last 08/21 kernel and NT the new 3.8 V original battery also lasts longer and is more reliable than ever.

Only a little remark to do so far... i set the language to Italian and everytime the battery went 15-14 % SystemUI started crashing. Solved by turning off the phone, charging the battery and setting the language to English. Others could follow soon, but my phone is stable so far, no corrupt baseband/imei experienced, nor bricks of any kind, everytime i was about to flash something i cleaned cache and dalvik (and did a factory reset before a new ROM, except with the last one).

The phone's literally reborned. A big thank you to ace2nutzer, CM and TC. Keep up with the good work.
[Galaxy Ace II Android Development] Dr360r:
Overnight battery issue

Tonight my battery dropped from 75% to 28% even if the screen was off. Before downing it to 75% i charged it to 100%, refreshed the statistics through NT 1.6.1 and cleaned the statistics in Settings (not NT) menu. Android OS took 51%, Screen 17%, Browser 14% and Google Play Services about 2% (so that's not the culprit; i activated Privacy guard for it and denied Keep Awake and Wake up). Cpu total 1h 18m 46s and Keep Awake 7h 47m 50s for Android OS. Data and WiFi was off. Location was set to high accuracy. Apparently the phone won't enter deep sleep for some reason. There's another app down the statistics list and it's named Android System. This took 8% instead. Systemui took 2%. The phone was on offline mode all the time

Here's another screen about how GMS behaves in the background

Sounds like a wakelock issue

Kernel is still 0821
[Galaxy Ace II Android Development] tbela83:
Hey!

Is there any solution for this problem? :

It started with the power button's error (it didn't worked), then it's restarted randomly, even in the recovery menu. After a format and the reinstall the problem is still occur, though not that often. An other problem after the reinstall the mobile internet doesn't work, only the wifi.

Thank you for the help!
[Galaxy Ace II Android Development] Dr360r:
Sounds like you flashed the ROM on a Gingerbread baseband (i8160XXLK2 for example). I flashed it upon i8160XXNA1 (a JB baseband) and didn't experience this kind of problem. Or maybe codina instead of codinap (you installed the i8160 build on a i8160P) or the other way.

Wait. Did you mention format? What did you format? I never formatted anything except cache and dalvik cache while tinkering around with custom ROMs.
[Galaxy Ace II Android Development] tbela83:
The rom worked for me for 2 months without any problem. Before the install there was 4.x android on the phone.

---------- Post added at 01:02 PM ---------- Previous post was at 12:58 PM ----------

First I formatted only the cache and the dalvik cache, but the problem still occured, so I formatted everything.
[Galaxy Ace II Android Development] Dr360r:
Wrong. You didn't need to do that, a factory reset\wipe data or even flashing a stock ROM was enough. This evidently formatted modemfs also. Hope it didn't wipe out the IMEI, i've read somewhere on this site that IMEI and basebands are stored separately on the ACE 2 so maybe there's still a chance to fix it. I don't know what you can do now, don't want to mislead you or others with the same issue. Let's wait for other users or maybe ace2nutzer. Look for phone info in the meantime and tell me if it shows up Baseband: XXXX and the IMEI
[Galaxy Ace II Android Development] tbela83:
OK! Thank you!
[Galaxy Ace II Android Development] shaqman89:
@Up

Did you check your baseband and IMEI?

If it's still there, it might be worth to check the APN for your mobile connection.
[Galaxy Ace II Android Development] greeceeeee:
I have done clean install but the flash light problem still exists.....the first time I press it works and then it worka again after a few minutes
[Galaxy Ace II Android Development] Yønn:
First of all Thanks a lot to ace2nutzer, Chrono and all the other devs who helped this project.

I have a I8160P model, and I use the updated Kernels and ROM from ace2nutzer for a long time, always following the updates and trying to do the installation as explained.

So now I'm using :

- Kernel 20150821

- ROM 20150714 (with patch1)

- Gapps HDPI 20150617

- NovaThor Settings 1.6.1

Everything works pretty fine and much better than ever. So thank you all for this great job.

The only remaining problem is the Google Play Services FC, which I have for several months.

I've tried the fix consisting in clearing the data of several Google Apps (I did it from the app manager), link below :

http://xdaforums.com/showpost.php?p=61407681&postcount=2193

But I still get FC especially when using GPS.

Maybe I did not it properly or I did not apply the good fix...

Is there anybody in the same situation ?

Is there another way to fix this problem ?

Thanks for your support.
[Galaxy Ace II Android Development] ace2nutzer:
@up

u did everything correct. The G.P.S. FC Issue is still present for some reason .. but i suspect it's due to outdated CM Sources ..... actually i'm very busy with implementing/updating things in kernel .. and i'll also finally update the CM Sources .. .. so u just need to sit and drink an tea :)

I hope it's completely fixed with the up coming CM11 Update (final snapshot)
[Galaxy Ace II Android Development] Yønn:
OK thanks for your feedback. :)

Will wait for next updates.
[Galaxy Ace II Android Development] Dr360r:
I solved my battery drain issue. I had to shut off SystemUpdateServices in Google Play Services and the Google play services framework. Denied keep awake and wake up to both apps too but left location on. So it's a wakelock issue even if the M9 (the CM milestone, not the gun :laugh: ) was meant to fix it in the changelog. Lets hope the snapshot solves this issue definitely.
[Galaxy Ace II Android Development] tbela83:
At the baseband it says

XXXX

The IMEI is fine. At least is is give a number if I type the *#06# in.

I don't remember that I formatted the modemfs too, maybe I did. Could it be the problem fo the mobile net? How can I restore it?

Thank you in advance.
[Galaxy Ace II Android Development] shaqman89:
If you could make calls, it's most likely APN issue. Have you checked whether you have your APN configured correctly?
[Galaxy Ace II Android Development] ace2nutzer:
yes u can fix this.. search here in forum for i8160 + modemfs

u'll find cwm flashable update.zip but pay attention for 8160 or 8160P modemfs file ....
[Galaxy Ace II Android Development] tbela83:
OK! Thank you! I will try it. My model number is GT-I8160, so I guess I need the 8160 file.
[Galaxy Ace II Android Development] Dr360r:
Open the cover, remove the battery and check if the IMEI is correct to be sure. You need to either flash a 4.x custom ROM on a GB baseband or format /modemfs to get baseband XXXX.
[Galaxy Ace II Android Development] tbela83:
Problem solved. Thank you very much for everyone! :highfive:
[Galaxy Ace II Android Development] Dr360r:
So IMEI is definitely stored elsewhere. Next time no need to format /modemfs or anything else except dalvik and cache.
