yes, that's right too :)

yes this is normal .. as long u'll not stress the RAM too much.. then u'll not have problems with freezes or even reboots.

Yes, more battery lifetime ... but u're right.. the biggest problem is at the moment again the google play services .. that sucks :)

Yes :)

At the beginning of ace2nutzer kernel development the first thing what i've disabled was KSM and zRam ... but then many users complained about worsening in Multitasking .. and u guys forced me to enabled it again ...

Now we've zRam, and u guys are disabling this like hell ... I'm not :mad: .. but it's just funny thing :highfive:

Have blackscreen in recovery on latest build.

Can't make logact, you know why)
[Galaxy Ace II Android Development] manthes:
No BS for me.

Maybe it is a stupid question but is it possible undervolting gpu to make phone smoother? I don't think that is just my idea
[Galaxy Ace II Android Development] Dr360r:
I have a black screen instead of recovery too. Can't do nandroid backups anymore. I run WS2401. The reason probably lies here.
[Galaxy Ace II Android Development] shaqman89:
I think the goal of undervolting is for battery life, rather than smoothness.

[Galaxy Ace II Android Development] soko3:
[MENTION=5840412]ace2nutzer[/MENTION] what about gpu overclocking?

and can we change gpu autoboost parameters, or gpu clock need to be 400 mhz static???
[Galaxy Ace II Android Development] ace2nutzer:
u hav problem with google services... use AutorunManager to disable that service..

Or format system and flash latest rom + latest pico gapps.. that it's also fixed.

About GPU OC..

At the Moment let it all @ default

I'm working very hard to release final CM 11 Build incl. kernel and Full F2FS Support, and incl. NT-APP .. for GPU OC... but without CPU / GPU UV and without Mali GPU AutoBoost.. because 1. I'll let NT-APP org.. (to much work for building this app.. need to install java, android SDK etc..) and because this GPU Gov. is really useless ! - Till Min. CPU 200Mhz the GPU will run @ half speed.. therefore even on GPU static clock: 600 Mhz.. in IDLE u've 300Mhz .... and read ahaed kb have no effect on NT-APP.. i've entirend also permissions for that.. because it's setting wrong values.. therefore i've writed an optimazation script (init.d) that sets this Value @ 512kb .. But all the other things works on NT_APP.
[Galaxy Ace II Android Development] ramanmono:
With latest TC build and latest 11/16 kernel I occasionally get random reboots. I never set CPU higher then 1000MHz.
[Galaxy Ace II Android Development] eaque:
Hi guys!

I have the latest CM11 and latest kernel by ace2nutzer for codinap and I have a huge drain (6.5% / h) and the kernel is responsible of 50% of this drain. So I was wondering how I can flash the original CM kernel!

Thanks :)
[Galaxy Ace II Android Development] Vexylle:
Got the same issue, just switched back to the 20141101_p1 build, had the best battery life :/
[Galaxy Ace II Android Development] eaque:
Also, when I enter a new contact on the phone (not synced with Google or anything, just in the phone), it works for few hours. Then, the contact disappears!

Am I the only one?
[Galaxy Ace II Android Development] tbronco75:
Hi Ace2Nutzer,

I can´t get to your download Site. I get an error, that the site doesn´t exist.

Do you have temporarly server problems?
[Galaxy Ace II Android Development] fluffi444:
Not Ace2Nutzer has - Dev-Host has problems... Just wait...

EDIT

Works again
[Galaxy Ace II Android Development] dv6661:
BlackScreen

any suggestion to handle blacksreen problem ?, it's very annoying :mad:

thanks before
[Galaxy Ace II Android Development] ace2nutzer:
@up

may solved in next build.. just wait.. I'll upload it in some Hours ...
[Galaxy Ace II Android Development] gRaB@:
I sould instal the new version as usual? because it stuck on samsung logo ;f
[Galaxy Ace II Android Development] crisis_trustee:
It is maybe neсessary to format /system, /data and /cashe into f2fs before flashing this new kernel?
[Galaxy Ace II Android Development] surfboardcm:
After install new kernel(wipe cache and Dalvik first) it stuck in Samsung logo. Back to previous...
[Galaxy Ace II Android Development] gRaB@:
i think so, like in chrono kernel ;f

I done like here and the same samsung logo
[Galaxy Ace II Android Development] manthes:
I know and that's why it is strange and i made the question
[Galaxy Ace II Android Development] yulligulli:
Also BS here. Any hints how to flash an old kernel (eg. by adb) ? Thanks!
[Galaxy Ace II Android Development] ace2nutzer:
Hmm it seems that only ws24 Is affected.

Here on s6d everything works.

Is the phone not booting at all ?

U guys with ws24 u can simply flash odin kernel... And then previuos kernel over cwm again. U can find odin kernel in my dev-hostt
[Galaxy Ace II Android Development] shoxieJESUS:
I can't flash anything via odin. my PC can't reconize my phone

Downloaded zwliew kernel and flash it via UKF. then flash 1108 build

Phone booting. reboot to recovery and catch BS
[Galaxy Ace II Android Development] Dr360r:
No ace2nutzer, my phone still booted.

However i flashed the mentioned kernel through Odin 3.07 (only adding it to PDA, and, by the way, that marked my first Odin flash ever) and then reverted back to 08/11 and now everything works like it should. Thank you for the fixing kernel.

Kirya12347, first install samsung usb drivers. And reboot in download mode. Once in reboot Odin should see your phone.

Whew, that was close.
[Galaxy Ace II Android Development] lab34:
Hi,

same here :(.

The phone is booting normaly. The BS is in recovery.

EDIT: with ws2401
[Galaxy Ace II Android Development] nikolas1274:
Same here, ws2401
[Galaxy Ace II Android Development] ace2nutzer:
okay guys ... if u know how much i hate that the Ace2 has 2 different LCD's ... every time i change drivers or optimizing LCD Driver.. usually i need to have 2 different Ace2 Phones .. this is really annoying... and that was a really bad idea from Samsung or even STE-Sony-Ericsson :mad:

I need just one information in order to found out which driver is missing:

I need to know when the Screen is Black ---> BS in recovery ... if the Backlight from the LCD is ON or OFF ... .. for this u need to go in an completely dark Room.

Also it would be better to provide dmesg during BS.

Example:

Boot to recovery ... u see BS (yes blackscreen, not bullshlt :D )

then connect the Phone with PC or laptop with working ADB ...

type:

adb shell
mount -t vfat -o rw /dev/block/mmcblk1p1 /sd-ext
dmesg > /sd-ext/dmesg.txt
cd /
umount sd-ext

then disconnect, and flash odin kernel and 08/11 kernel like a described before.

After that all, u can find in external sdcard the dmesg.txt
[Galaxy Ace II Android Development] manthes:
De ja vu :p:p:p:p:p

Sorry for spamming
[Galaxy Ace II Android Development] Dr360r:
LCD stays backlit during black screen on 21/11 kernel. Here's photo proof. Sorry, but i don't want to mess around with adb, i've never done it before.
[Galaxy Ace II Android Development] ace2nutzer:
Thx ! So backlight is ON ...

Hmm I'll make later new test-build ...

btw: nothing can happen if u do copy and paste ... those commands are not dangerous. But probably i don't need the log.
[Galaxy Ace II Android Development] ace2nutzer:
Okay, i made right now 3 test-builds ... so if somebody want to test those builds ... ;)

backlight_generic_ace2nutzer.zip

lcd_class_device_ace2nutzer.zip

ws2401_dsi_ace2nutzer.zip

One of them should work ... but please test them all .. and report if the LCD works or not ....

AND:

on test build: ws2401_dsi ... this is very new driver .. we've never used this before .. i just found it in the kernel config. So on this Build, if the LCD Works at all, please boot also to the system and check if it works smoother or not ... also check how about screen tearings ... ;)

Have Fun !!
[Galaxy Ace II Android Development] Dr360r:
I've tried the first two. The first still gives black screen if you go to recovery. With the second (lcd_class_device_ace2nutzer.zip) everything works fine (except google images) and the recovery screen regularly appears.

I won't be flashing the third, because this is my only phone.

Someone else already did it, however.
[Galaxy Ace II Android Development] ace2nutzer:
many thanks guys !! U are the best Community ever !!!!! :good::good::good:

I'll make tomorrow new kernel.

Temp fix. for google images ...

With the Stock Browser: Just switch to "desktop mode"
[Galaxy Ace II Android Development] lab34:
Hi, just to share my experience and my discover with flashing the emergency kernel you provide:

I don't know why, but I didn't succed with odin 3.07... I have installed Samsung Drivers... Everthing is good till I click on start, I'm stuck on Smddownload...

I tried on two differents computers (8.1 and 7)

After spending two hours I found this fantastic tool:

http://xdaforums.com/showthread.php?t=2137598

And it works ! So easily ! :laugh:
[Galaxy Ace II Android Development] Dr360r:
Have you put the phone on download mode before clicking start? Strange, everything worked right with me.
[Galaxy Ace II Android Development] miryn:
I guess You're trying to install an unpacked .zip. Just don't unpack it and it'll work :good:
[Galaxy Ace II Android Development] Dr360r:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Generally speaking you only open .tar (tarballs) if you need to work with what's inside. The downloaded ODIN kernel comes as a .tar which should be put "as is" in the PDA field.
[Galaxy Ace II Android Development] lab34:
Yes, I was trying to flash the kernel.bin.md5...

And it says on the log windows:

<OSM> Enter CS for MD5..

<OSM> Check MD5.. Do not unplug the cable..

<OSM> Please wait..

<OSM> kernel.bin.md5 is valid.

<OSM> Checking MD5 finished Sucessfully..

<OSM> Leave CS..

But if I choose ace2nutzer.kernel.4.4.x_codina.p.l_ODIN.tar , it doesn't log anything , so I'm perplex... :confused:

I will no try further, because my phone is working now...
[Galaxy Ace II Android Development] Dr360r:
I flashed codina_kernel_ODIN_CM11_ext4.tar through ODIN btw (devhost->codina->4.4.4), not the one you find right after opening up his devhost.
[Galaxy Ace II Android Development] kuba130000:
Which partitions can I format to have "brand new" phone (with no system) and install Vanir 4.4.4 and ace2nutzer Kernel?

I want to delete all files in my phone.
[Galaxy Ace II Android Development] gepel:
I tryied the 3rd one but the phone stuck on boot logo. I used the emergency kernel and now I m back on previous kernel.
[Galaxy Ace II Android Development] Dr360r:
I thought it would do that, so i didn't flash it. I was right.
[Galaxy Ace II Android Development] shadow252:
If you want to delete everything then you should format system, data, cache, dalvik cache, sdcard0(internal sdcard).
[Galaxy Ace II Android Development] ace2nutzer:
The odin kernel on the root of dev-host is just newer + universal.

The one called specific codina, works also.. But it' just outdated.

Hmm i'll build New odin kernel too with fixed cwm blackscreen. i need it very rare.. But there is bs too on my phone.. Just sometimes.. But that nerves me.

Btw don't use odin kernel for daily usage... Because it doesnt install needed modules !

[Galaxy Ace II Android Development] giginski:
Hello pls help me, im on kernel from 21.11, when try go to recovery got blackscreen how esle can i intall new kernel which fix blackscreen recovery. ?

I see need to use emergency kernel using odin but in which section need to put that file PDA ??
[Galaxy Ace II Android Development] shaqman89:
Use Odin to flash kernel, you should fine the kernel has an Odin name in it.
[Galaxy Ace II Android Development] giginski:
But in which section need to put that file PDA ??
[Galaxy Ace II Android Development] lab34:
@up: here is what I did:

I went here: http://d-h.st/users/ace2nutzer/?fld_id=0#files

and downloaded this : ace2nutzer.kernel.4.4.x_codina.p.l_ODIN.tar

And I flashed it (the kernel.bin.md5) with this tool: https://play.google.com/store/apps/details?id=com.frapeti.ukflash2

After that you can reboot on recovery, and you can immediately flash ace2nutzer.kernel.4.4.x_20151122_codina.p.l.zip
[Galaxy Ace II Android Development] shaqman89:
Yes, PDA field. But you could also try the suggestion from above.
[Galaxy Ace II Android Development] giginski:
now when i flashed by odin and tried reboot to recovery it just reboot again to the system not to recovery. I went to recovery using old way, just off phone then power on ,vol up and middle button, and flashed new kernel after reeboot i check can i go to recovery by choosing recovery mod. Thx for fast answer.

EDit. All is good now thx.
[Galaxy Ace II Android Development] manthes:
I am back to 21/11. I think that it is much better than 22/11. Better scrolling for me
[Galaxy Ace II Android Development] ace2nutzer:
Thx for the report !

Yes this is possible.

Right Now fixed !
[Galaxy Ace II Android Development] Dr360r:
You mean you're about to compile a new kernel?
[Galaxy Ace II Android Development] ace2nutzer:
yes with many more optimizations .. especially ram management incl. swap (zram)...
[Galaxy Ace II Android Development] kuba130000:
[MENTION=5840412]ace2nutzer[/MENTION]

Can we increase RAM by app like this https://play.google.com/store/apps/details?id=artur.m3rv.myszka.speedupswap&hl=pl or https://play.google.com/store/apps/details?id=org.webappid.simplerootswap&hl=pl

Is this make phone more smoothness?

Then should be primary 768MB Ram + zRam from Your kernel + swap from app, or am I wrong?
[Galaxy Ace II Android Development] ace2nutzer:
@up

don't use such dirty apps, they will just harm your phone .. do u really think an very universal app can do better work than a developer for this Device ??
[Galaxy Ace II Android Development] kuba130000:
No, I do think so.

I think u are very great developer for our device, of course. :D

What u think, which combination is better?

Vanir 4.4.4 with Your kernel or CM11 (from this topic) with your kernel?
[Galaxy Ace II Android Development] ChronoMonochrome:
It's not a best idea to use zRam and swap at the same time. There are chances of LRU (least recently used) inversion: the most recently swapped data that goes to the slow disk, while inactive pages that were swapped out long ago will remain in the fast ZRAM. Not to mention about how swap works on flash devices, it's unlike to how swap works on a fast HDDs/SSDs.
[Galaxy Ace II Android Development] ace2nutzer:
Probably Vanir for now ;)

If i'm got u right, isn't there such a Priority system for such cases ??

At least here on Linux (Laptop) i had one time zram + swap enabled .. but zram had priority 1 and swap had prio 2.

I've checked this during high mem usage ... the Ram devices filled in this order:

1. Real RAM

2. zRam (block0, block1 etc..)

3. SWAP

At least here on Laptop works correctly ...

u can check with command: swapon -s
[Galaxy Ace II Android Development] Culateralligator:
IMO Vanir and CM11-Ace2Nutzer along with AOSP J-Team are best KKs. I've tried all of them with 8/11 kernel and they worked fast and smooth. Right now I have AOSP with Ace2Nutzer kernel.

BTW, for much better battery drain and smoothness, there's a great thread:

http://xdaforums.com/android/general/guide-extreme-battery-life-t3095884
[Galaxy Ace II Android Development] ace2nutzer:
just a quick check.. and i saw greenify ... that app is contraproductive on android phone.

Maybe the other things are ok.
[Galaxy Ace II Android Development] Culateralligator:
Interesting. Why is Greenify contraproductive?

Amplify and PowerNap work very good in my phone.
[Galaxy Ace II Android Development] ace2nutzer:
because it serves nothing xD

in general:

every app that kills services or apps (greenify, taskkiller etc.. ) are useless on android.

Android his own low-memory-killer manage this already.

also it can even drain more battery instead to save it .. because reloading an app cost more power than simply reload from RAM (less CPU Time usuage ;) )

The only thing what makes sense is if u want to freeze some apps that u only need so let say 1x per month .. then it's ok to freeze instead to delete.
[Galaxy Ace II Android Development] Dr360r:
Crystal clear. Greenify uninstalled.
[Galaxy Ace II Android Development] Culateralligator:
I'm using Greenify since JB mainly for clearing its ridiculous accessible 485 MB of Ram. But now with zRam & your explanation it's time to try disabling it.

The guide I mentioned adjusts Greenify to work only every 30 minutes (using Amplify) in order to drain less battery, but I'll try uninstalling the app and check what happens.

You changed also zram size to my favorite 150 mb :p:D
[Galaxy Ace II Android Development] ace2nutzer:
@ up

read changelogs ... i've been removed boottime check from kernel in previous build .... that's why i've removed it from NT-APP too .. otherwise it'll crash the App if somebody tap on Boottime check.
[Galaxy Ace II Android Development] ace2nutzer:
yes u're lucky guy now :) 150MB is 25% of the 629MB available RAM on userspace.

I've tested many sizes .. and 150MB seems to be perfect ... it gives the best performance.

It was a really bad idea to use over 600MB of zRam..

Anyway ... before the minimum needed was 300MB zRam ... but now with some optimizations, 150MB are enough !
[Galaxy Ace II Android Development] Dr360r:
Anyway, kernel by kernel, you're turning what once was, in my hands and opinion, little more than an expensive doorstop into a flagship-feeling phone.
[Galaxy Ace II Android Development] Culateralligator:

Hope doping my phone this way won't have side effects. XD

[Galaxy Ace II Android Development] Joline:
Hi,

I'm still on TeamCanjica CM11 (End of 2014).

What is the proposed ROM right now, running with this kernel?

In which sequence should I install that? First update the ROM and then install that kernel?

Thanks.
[Galaxy Ace II Android Development] shaqman89:
VanirKK seems the best for my need in the moment. Maybe until ace2nutzer finishes his optimization on cm11.

Yes, just flash the ROM followed by the kernel. Remember to wipe cache and data before to be safe.
[Galaxy Ace II Android Development] miryn:
Something is wrong with lcd freq values. In init file, echo 5 is 50Mhz (stock WS..) and echo 6 is 57Mhz (kernel default WS..) but in mcde/lcd_clk

[5] is 44.37 (S6D), [6] is 49,92(WS..) and [7] is 57.05.

Also 2D is a little bit worse than with 22.11's kernel (tested on few freq options).
[Galaxy Ace II Android Development] Dr360r:
With the new ROM it will be like Kerosene+Nitric Acid=Rocket Fuel for our phone! At the time we have a good fuel, all we need now is the Oxidizer! :laugh:
[Galaxy Ace II Android Development] ace2nutzer:
lol are u still using that outdated script for lcd freq ?! There is no need to change lcd freq at all. Kernel defaults, are best.

I added some time ago 44mhz lcd freq for s6d :)
[Galaxy Ace II Android Development] miryn:
Ok, I'm testing CM 11 since 2 days and just thought it is still actual.

But it doesn't change the fact that 2D on the latest kernel is worse than previous from 22.11.

Also I'm surprised that no one has reported the problem with receiving incoming calls (the reason why i tested this rom cuz Vanir has the same problem)
[Galaxy Ace II Android Development] lab34:
hi, @up

hmmm... I don't have problem with receiving calls. :confused:
[Galaxy Ace II Android Development] ace2nutzer:
tested right now 2d game vertical and horizontal.

Also tested calls incoming and out .. no problems at all.

Maybe u should remove all your init.d scripts .. or better try wipe data.
