Don't use fast reboot, it's buggy.

But maybe a stability problem.. next build is 100% stable.. i did a try to reduce CPU Voltages in order to save some power.. but it wasn't also stable for me.

@up

next build is even more better in performance/smoothness and little fix for less battery draining.. But don't expect too much in battery lifetime.. it's what it is :)

U all should know:

The Priority of this Kernel is:

1. Stability

2. Performance

3. Smoothness

4. Fast response

5. Battery Lifetime

As u can see Battery Lifetime is at last, but this doesn't mean that i did nothing in order to increase battey lifetime... i've already used ALL Power-saving features that do not decrease Point: 1 - 4. So i can do nothing.. it's already optimized. But as i said, next build i'll adjust WS2401 Driver.. unfortunately i've here only S6D .. (this is running perfectly) so when i drive this days to my mother (ace2 with ws2401) then i can check this driver... and make new build here... :highfive:
[Galaxy Ace II Android Development] xo.en:
Damn :D Sounds serious....still, nice, GOOD rom is most part of goals you posted, right?

Trust me, good kernel is not enough.

(Sorry, couldn't resist).

[MENTION=5840412]ace2nutzer[/MENTION] you have the best kernel in perfomance and ChronoMonochrome the best battery lifetime on his kernel,is it possible to take some settings from his own kernel to improve yours?
[Galaxy Ace II Android Development] ace2nutzer:
Yes of course... :) Everybody can customize this or other kernels with init.d scripts.... Okay it's not possible to change everything with scripts.. But many and important things u can change it over scripts. If u've questions just ask...

Hello,

Is there any step-by-step tutorial to installing this i8160 ROM ?

What CWM version to install a link wil be handy :)

What GAPPS to install also a link wil be handy ;)

Thanks in advance for any help!

Seriously dude, search. This has been answered for quite a few times.

Here is one: http://xdaforums.com/showpost.php?p=61518546&postcount=2236 (which I got from searching in under than 1 minute).

Anyway, good luck. :)
[Galaxy Ace II Android Development] Vaako:
Thanks!!!!
[Galaxy Ace II Android Development] Eleichstetten:
Well, I think most of the problems with battery lifetime are not related to kernel optimizations, but are caused by the device not

swithing to deep sleep.

Actually I installed Chronomonochrome´s ROM. It´s does not feel as dynamic as yours, bat has no issues with deep sleep.

I used the same GAPPS as with your ROM and did not install more than BBS and CPU ID and in the end, the same google play

services. Sometimes I get an message, that play services are FC, but that is causing no troubles so far.

I have the strong feeling, that this issue is more connected to the ROM itself (not the kernel).
[Galaxy Ace II Android Development] shaqman89:
I'm not quite sure on that.

I don't actually have issues with deep sleep on ace2nutzer kernel (usually around 50-70%) is deep sleep, and it is quite consistent with my usual usage. And then just 3 days ago, I changed to ChronoMonochrome's kernel and with similar deep sleep amount I got way better on battery life, though not as smooth as ace's kernel. The biggest difference is on idle time, on ace2nutzer's I couldn't get below 7%/hrs, while on ChronoMonochrome's I could get around 1,3%/hrs.

Note, all of this are tested with ace2nutzer latest ROM. If we are to assume it is purely ROM related, then it shouldn't yield too much of a difference. Of course, I am not saying that ROM doesn't make a difference.
[Galaxy Ace II Android Development] ace2nutzer:
lol u guys when installing again different rom and installing the gapps then u've first the google play services version from the gapps.. wich are maybe lesser problematic. But after an reboot with connected wifi the Google Play Services will update to the latest version and then maybe some problems begins... but anyway for me still everything perfect ..

It's a really bad idea to change continuously the ROM/gapps without wiping data.. that will cause some messed up and the problem with deep-sleep and FC will start again ... or try to wipe data of all google apps incl. market feedback agent.. for me works... and of course, u need to repeat this annoying job after changing the ROM and gapps.. that's why it's better to stay on one rom... ;)
[Galaxy Ace II Android Development] shaqman89:
@up

That's so true. I didn't actually changed anything other than the kernel. So I still am on your ROM with the latest gapps after update.
[Galaxy Ace II Android Development] Eleichstetten:
Well, maybe I should clarify my procedures:

I never kept anything, I did always a clean install.

That means:

1. Wipe data/factory reset

2. wipe cache and dalvik cache

3. Format system

4. Install the ROM: cm-11-20150610-UNOFFICIAL-codina.zip (ace2nutzer) or cm-11-20150505-UNOFFICIAL-codina.zip (chronomonochrome)

5. install GAPPS pa_gapps_modular-pico-4.4.4-20150308-signed

6: reboot system and configure google account

7. Install BBS and CPU Spy

8. wait until google play services are automatically updated to 7.5.74

9. several restarts in between

10. check deep sleep behaviour after some hours of non usage

With Ace2Nutzer Rom: Deep Sleep = 0 %

With Chronomonochrome ROM: Deep Sleep = 93%

(phone has not been used)

I did repeat this 3 times (3 new installations of each ROM). Each time the same result.

If this problem does not occur with your device: maybe hardware related?

Mine is a codina WITHOUT NFC. And yours?

Ok, I see that yours (ace2nutzer) is codina-p
[Galaxy Ace II Android Development] ace2nutzer:
@ up

before reboot the phone to configure the Google account..

it's better to power off and flash first always latest kernel .. before starting ...

Anyway really strange .. for me it works like always perfect.. i don't see any difference ..

Right now tested:

my Phone goes into deep sleep after 3 Seconds (after screen OFF) :eek:
[Galaxy Ace II Android Development] Eleichstetten:
Well, I also tried installs with actual kernel, but did not change anything.

Therefore I tried to reduce to the max.

Maybe NFC?
[Galaxy Ace II Android Development] ace2nutzer:
maybe possible... since NFC Driver is also present on codina kernel .. but then everybody should have problems .. because codinap users are quite low here...

it's better to catch tomorrow the BBS Log and post here .. don't forget to start BBS then install it as system app (one tap in the app) and then reboot the Phone.. and let it run the whole night... otherwise it'll not work.
[Galaxy Ace II Android Development] Eleichstetten:
Ok, understood. Will take care of this, today in the evening.

The phone is actually configured with ChronoMonochrome´s ROM. Therefore the results maybe not of interest.

(I´ve also installed 2 or 3 Apps, so it´s nomore totally clean)

But I will provide them anyway to check if the logs are ok. Then I will change to your ROM, to see the difference.

OK. Attachments (Logs and Screenshot) added.
[Galaxy Ace II Android Development] Eleichstetten:
Added Stats as requested to my #2293

Well, maybe not everybody is able to pinpoint short battery live to deep sleep issues and therefore is just complaining about battery live?

Maybe your kernel optimizations are close to perfect, but are "overwriten" by a deep sleep issue?
[Galaxy Ace II Android Development] Eleichstetten:
And now the BBS Stats of Ace2Nutzer´s ROM.
[Galaxy Ace II Android Development] greeceeeee:
I turned on airplane mode and after few minutes I disabled it then I tried to turn on wifi but does not work,I rebooted device but nothing,I tried switch off/ on,remove battery but nothing....wifi is still off
[Galaxy Ace II Android Development] gepel:
I have enabled the airplane mode dozen of times but i never faced the problem that you have described above. Try to clean your cache or delete the dalvik cache .
[Galaxy Ace II Android Development] Vaako:
So when exactly at wich point do we have to install the "codina_kernel_cm11_20150216_ext4_ace2nutzer.zip" 9.28MB size ?

Like ace2nutzer says:

I guess that this is the latest kernel: codina_kernel_cm11_20150216_ext4_ace2nutzer.zip and is 9.28MB in size ?

---------- Post added at 01:02 PM ---------- Previous post was at 12:40 PM ----------

So do we have to flash:

1. ROM

2. GAPPS

3. lates KERNEL

4. Reboot

Or do I mis-understand

what is the latest kernel version?
[Galaxy Ace II Android Development] Eleichstetten:
[MENTION=553189]Vaako[/MENTION]: Did send you PM. If it didn´t work: just tell it to me.

Ace2Nutzer´s actual kernel should be here: http://xda.mister-freeze.eu/XDA-fil...e2nutzer.kernel.4.4.x_20150620_codina.p.l.zip
[Galaxy Ace II Android Development] Eleichstetten:
OK. No pain, no gain. Or "Wer nicht wagt, der nicht gewinnt".

Now I used ChronoMonochromes ROM, the GAPPS I mentioned before and Ace2Nutzer´s newest Kernel.

Flashed all in sequence. After that I switched off as recommended.

Switched on, installed all as I did before and....

Deep Sleep is fine.

Let´s wait what´s about the "Rest".
[Galaxy Ace II Android Development] Vaako:
Thank you so much Eleichstetten !

One thing is not entirely clear for me, at wich point do we flash the kernel?
[Galaxy Ace II Android Development] ace2nutzer:
hmm.. it's just Google Play Services Wakelock .. this is an known issue and u've to disable this wakelock from Settings ------> Privacy ----> extended ----> find google Play Services and "denied" wakelock and keep awake .. .. after this, it's impossible that Google Play Services will continue to keep the Phone awake after screen off !

Check Modules in /system/lib/modules ... check also free space on /system .... and then flash latest kernel.. and make sure that the Modules in the zip package are really copied in the path what i've already mentioned here... of course this operation is usually automatically .. but for some reasons it fails ...

any time ! but it makes sense at last..

example:

ROM with kernel version V1.0

Kernel Version separate zip with V.1.1

flashing first the rom and then kernel.. u'll have V1.1

But if it's viceversa:

ROM with kernel version V1.1

Kernel Version separate zip with V.1.0

flashing first the rom and then kernel.. u'll have V1.0

in this case it's better to flash only the ROM to have newest version V1.1 and so on .... ;)
[Galaxy Ace II Android Development] Eleichstetten:
[MENTION=5840412]ace2nutzer[/MENTION]:

I already tried to disable Wakelocks and Keep Awake of Google Play Services. Did not solve the issue. But maybe I made something wrong. So I will repeate this later.

Now I would like to stay for some time with the mixture I described above. Usually I would expect to get some FC from Google Play Services.

This was, what I got using ChronoMonochrome´s ROM the last time. (Installed from scratch, without any attempt to fix that issue)

Until now, no FCs.

Could that be caused by your Kernel?
[Galaxy Ace II Android Development] slake84:
What is the installation procedure when comming from original JB:

1. Kernel

2. Rom

3. GApps (those http://xdaforums.com/showthread.php?t=2779598 are ok)

?

Or maybe ace2nutzer ROM already contains latest kernel so ROM and GApps installation is enough?

And what about repartition, do I have to do this before installation?
[Galaxy Ace II Android Development] lachezar1990:
Network Problem

Hi,

First thanks Ace2Nutzer. Your kernel is really nice.

Unfortunately I have a problem with my network connection. My phone loses connection sometimes and this happens within 2-3 days, sometimes every single day, and only when I end calls. I'm using your latest kernel with latest CM11. I have never had such problems with stock ROMs 2.3.6 and 4.1.2.

Does anyone have any idea? :)

Thanks in advance and sorry for my poor English skills ;)
[Galaxy Ace II Android Development] yeka:
A spend all of my time today for this phone .. Lol

I've google play service FC issue . .

I try in Chronomonochrome's ROM and team canija ROM .. I'am already try your kernel and Chromonochrome kernel ..

And the problem still exist ..

I've already try differents GAPPS .. Pa micro,Pa mini, Minimize, and also full stock GAPPS and others .. But i've still Google play service FC ..

Pls help mee.. ;(
[Galaxy Ace II Android Development] ace2nutzer:
wait for next kernel update.

use the search function here in this thread .. search for: "google play services" u'll find an workaround how to fix G.P.S. FC issue..

but only Valid for the CM11 from my FTP Server and gapps from my Dev-Host !
[Galaxy Ace II Android Development] aj10:
i am finding something is draining my battery a bit. android os usage is 20-25% under battery. i have 'applied' the google play store and play services fixes in privacy guard.

i am using the latest kernel and 20150526 rom.

bbs reports high usage of wakelock under graphs. no data connection and no or unknown signal are both at 98% - but i have no signal problems. is there anything i can disable for android os in privacy guard?
[Galaxy Ace II Android Development] gothicVI:
Probably take a look at amplify in order to block alarms and wakelocks. It might fit your needs :cool:
[Galaxy Ace II Android Development] Eleichstetten:
Keep in mind: ChronoMonochrome ROM and Ace2Nutzer Kernel:

Actual state after 2 days of low usage. Deep Sleep fine, sometimes FC of Google Play Services (as expected).
[Galaxy Ace II Android Development] ace2nutzer:
@ up

i don't need any logs from an working system .. it's useless, u know ? because there is nothing to fix :)

btw: today i had again one FC for G.P.S. after an reboot .. it's very rarely .. it didn't happened after every reboot ... but just sometimes !

Well, i was angry enough to flash another gapps ... and till now no one FC .. and deep sleep still working ...

It's a real mystery why it won't work with your Phone ... what say other users ?? Only one user with this problem ??

Anyway ... i hope this is better .. and FC of g.p.s is finally fixed for ever:

- format system

- wipe cache

- wipe dalvik cache

- flash latest CM11 here

- flash linked gapps here from my dev-host

- flash latest kernel here

- reboot system

Download latest pico gapps:

Don´t worry. Will not bother you with useless logs. :D

Just did hope they would be useful for you.

So, I will try your recommended configuration.
[Galaxy Ace II Android Development] Eleichstetten:
Well, I did install as recommended. ->> Deep Sleep not working.

So I hope, these Logs are not useless. :fingers-crossed:
[Galaxy Ace II Android Development] ace2nutzer:
Hmm actually i don't have more ideas .. it's really strange ... :confused:

It's just Google Play Services Wakelock and nothing else :)

Maybe u can make an video how u do disable wakelock of Google Play Services and upload it to YT or just upload as .zip?

btw: check deep sleep with this app: A1 CPU Tool very nice app.. and great stats of CPU Freqs/Steps Usage ..
[Galaxy Ace II Android Development] Eleichstetten:
Disabling wakelocks of Google Play Services (Wakeup + Keep awake) did help. Deep sleep is fine again.

Maybe cleaning of Dalvik Cache was missing the last time I tried this.

2 questions

Hello all, i havent tried the last kernels, but i have 2 questions.

1- since i quitted the official ROM for cyanogen (10.2 and then 11, the version of ace2nutzer 20141118 with his kernel of 20141212), it is impossible for me to connect to a wifi 802.1.x. THis system is used in enterprises and universities. In particular, as i work in a university, i need to connect to the eduroam network which exists all over the world (eduroam.org). I tried all the tricks found with google but none of them worked (mainly modifying the wpa_supplicant and wpa_supplicant.conf files) .

It used to work with the official ROM but impossible now.

Can you connect to such networks ?

2- Is USB OTG enabled for the ace 2 ? I would like to read cards with the USB plug.

Thanks Ace2Nutzer for all the developments :good:
[Galaxy Ace II Android Development] bidug:
Hi, I use 802.1X every day in my university and I never had any problem with any of the kernel's version. It's not Eduroam, but something similar.
[Galaxy Ace II Android Development] Fabbb2:
Do you have to enter a login and password to connect to it ?

Have you ever tried eduroam ?
[Galaxy Ace II Android Development] bidug:
Yeah of course, as it's a 802.1X network.

Unfortunately i don't have any id/pass for eduroam network because my school doesn't provide any.

Hi,

the lastest kernel as of 0620 kills my bootloder!

I tried in different ways to get this beast working ...

A completely fresh install with the lastest cm11-image as of 0617 togehter with the latest kernel doesen't work.

Well ... instead of this I was happy about my current backup :)

Has anybody the same issue?

Greets ... Peedy
[Galaxy Ace II Android Development] ace2nutzer:
@ up

no one ROM or Kernel touch the Bootloader ;)

U just have to check Filesystem (EXT4/F2FS)

haha ... i told you all the time :o

It's maybe possible that this very old version of ROM + KErnel have such issues ... i can't provide bug fixes for such very old kernels..

you just need to flash latest ROM + Kernel .. it's anyway better ... ;)
[Galaxy Ace II Android Development] Eleichstetten:
Just for better and clear understandig:

When I installed the ROMs, I did clean up Dalvik Cache, for sure.

I just was not aware, that it maybe necessary to clean up Dalvik Cache after the rights of Google Play Services

have been cut for Keep Awake and Wakeup.

(Because I did try to cut the permissions earlier, but it was not working, until I finally cleaned up Dalvik Cache)

And to be honest: I still don´t understand why it should be necessary.

I´ve installed the actual ROM as of 20150610, the recommended GAPPS (see #2311) and last but not least,

the kernel as of 20150620.

After installation I had Deep Sleep issues, so I changed permissions of Google Play Services.

Maybe that´s not necessary in your case. It seems that I´m the only one with this issue.

So far it´s working fine.
[Galaxy Ace II Android Development] ace2nutzer:
Yeah works.. ROM is "Bugfree" .. the only one know small bug is that "fastreboot" messed with wifi ... so simply better to don't use it..

When i've time i'll check this.. maybe just a bug in bootscript.

Because this ROM here uses old CM Sources... that was CM Sources Bug ... now because we're using this Sources the Problem is back again.

But this is no Problem after applying the Google Play Services Battery drain Fix...

But anyway, If CM Source Bug or not, the Battery drain Fix is needed anyway.. if u want to reduce the wakeups :highfive:

OK, I tried it now, again with 0620 ... it's impossible for me to install it.

What i did before:

repartition with the orig PIT-file

flashing XXNB4 (I had have to format all Patritions and re-flash the Image)

After this procedure all f2fs-partitions has been killed and the space is formatted as standard.

installing root.zip

flashing cm-11-20150610-UNOFFICIAL-codina.zip

installing ace2nutzer.kernel.4.4.x_20150620_codina.p.l.zip

output during installation:

Mount /system

Delete old Modules

Erasing /boot partition before flashing Kernel

Format Hidden/Preload Partition as ext2

Unmount /system

Done :)​

after this, the Phone hangs on boot.

I tried it with a little trick:

I recovered /boot via advanced restore after installing the Kernel.

But after this, the system was buggy in different corners (e.g. cant't enable WLAN)

So, a recover of the latest Backup saved my day.

I ran out of Ideas ... please Help me ...

Cheers Peedy
