Good job [MENTION=5840412]ace2nutzer[/MENTION] :D

Gonna try it as soon as the f2fs support is ready :D
[Galaxy Ace II Android Development] monstro78:
Is your ROM compatible with f2fs???
[Galaxy Ace II Android Development] exodius48:
may be :D

btw, if i flash this codina_kernel_ODIN_cm11_20141028_ace2nutzer.tar via odin will this kernel increase counter bin?
[Galaxy Ace II Android Development] Andrewbons:
I can't enter CWM too. I wrote lots of post about that and no one really care about it.

I'll tell you what happened:

I bought my Ace II, stock recovery works great. I've installed temporary CWM and everything was ok. I've installed old CM11 TC and Nova versions and everything was ok.

When Chrono made his first kernel version with a CWM built in, i had the first black screen issue. Since there, i cannot enter any recovery (CM11 cwm, chrono cwm, stock cwm). Only TWRP works good but it can't mount external SD and i don't feel comfortable with it. I never had screen issue, never had a problem since now.

Solution: it randomly let me enter on recovery, but it's a pain in the ***.

I've tried to format everything, i also installed GB stock with stock repartition, nothing to do.

With this version i've tried lots of time but still cannot enter. Can you try changing CWM version? Maybe a older one, or just a different one. I can test it if you need help.

Actual situation: i've installed this kernel with your CM11, i had some bugs that i can fix formatting some partition, nothing bad. But i can't enter on recovery, so i have to flash stock version with odin -.- I suggest to make a stable version and then focus on those issues, i bet other users have them.

I've tried to flash kernel via Odin... Failed, dunno why

NLP Collector Wakelog is biggest.

Google wants to know where u are !!

Try Powersaving in Location Service.

Try Google Prefereces disable "dont know in english" -> google saving where u are -> disable this.

Maybe phone wants to submit where u are but in airplane no chance to submit. or maybe crashed google location service.

[Galaxy Ace II Android Development] poppmensa:
Hi,

I use poppmensa-20141108-codinap build and flashed ace2nutzer-20141106-kernel. I get some reboots per day, but I cannot categorize tham (there is no reason I can see). The log is always "too late", I cannot scroll back to the reason for rebooting. Any idea to get a longer log file?

On top of that, sometime the phone needs 2-10 seconds to "wake up" when the screen is black.

I had similar issues with kernel ace2nutzer-20141101-p1.
[Galaxy Ace II Android Development] artur1131:
blackscreen bug still exist for me on 0611 build...
[Galaxy Ace II Android Development] hypervenom27:
has been a days now since i flash your ROM and latest kernel, and i only get once blackscreen when first flash. but now it work like a charm, probably the best kitkat ROM and kernel that i've ever flash on my device :D, but there is one thing i don't know is it bug or not but when i connect my device on my laptop it never charge the battery.
[Galaxy Ace II Android Development] ace2nutzer:
**** ...

Hmm about the log:

I've reduced the Kernel Log Size to improve the performance.. But don't care about that.

ATM it's enough to descrive the Issue... That Sounds problems with CPU / CPU Driver / Voltages... and at least the Algorithm how the Phone switch the freq.. For me on this actually Kernel: CPU: 200/800 is very stable.. but 1Ghz is unstable.

Actually i test the new LiveOPP Driver from cocafe and mkaluza.. they did very good Work.. the Driver is, let me say, very very good .. ! Actually i see with this new Driver it can run stable with 200/1100 ... ---> 1150 Mhz Step is missing, but i'll add it.. and 1200Mhz is unstable for me, but 1,2 Ghz was never stable for me.. little bad CPU Quality :o

@ USB Charging:

it's not a Bug.. I've set the standard current for USB @ 300mA.. it seems too low.. i think next build default for USB and AC is 500mA .. but adjustable on NT APP.. and may be finally adding F2FS .. thanks [MENTION=5695278]ChronoMonochrome[/MENTION] for help with Git ... and at the same time the Sources for the next Build where online on Git :)
[Galaxy Ace II Android Development] poppmensa:
I never did manual OC and I don't really care about 5% speed gain for the price of reboots.

If I install your kernel and do not tweak anything, what's the frequencies used? Can I bound them to assure stability?
[Galaxy Ace II Android Development] PanAndrzej:
Can I use this kernel on AOSP for example?
[Galaxy Ace II Android Development] str3tch72:
Yes, on any 4.4 ROM.
[Galaxy Ace II Android Development] ace2nutzer:
For next build:

LiveOPP 2.2 - More Stabilty - More Smooth.

Everything Stock by default ... Even CPU GPU Voltages..

CPU: 200/800Mhz

GPU: 400Mhz

But CPU Configurable from 50Mhz - 1400Mhz :D:D:D

PS: Better LiveOPP Driver is not only for more stability on OC.. even if u DON'T OC.. it's even better to have it.. for more smoothness and powersave even on stock Freq'S !! :highfive:
[Galaxy Ace II Android Development] exodius48:
Bro, this morning i get blackscreen , I dont know why this bug come again. :(

Would you add it to your next build?
[Galaxy Ace II Android Development] rezniqsvk:
sry for stupid q but i read whole thread but was unable to find an answer

what makes the cracking sound while listening to music while screen is off its rly annoying , and how to fix this?
[Galaxy Ace II Android Development] BlueZ-:
Just use interactive governor and 800/200..scheduler sioplus or noop is the same for this...I have't got any stuttering with this settings

ACE 2, Which custom rom?

Hi Ace2Nutzer,

i installed a few days before your Optimized, Pre-rooted GB 2.3.6 ROM because the original JB was horrible. It works very nice. I have only the Problem that i cant install some apps (error phrasing or something like that) probadily because it is the older android Version.

Which custom Version can you recommand at the Moment? I found an cyanogen mod 11 called codina from oktober.

Can i install this Version, then install gapps, than i install your work: [Kernel] [3.0.101] [4.4.x] [TeamCanjica] Ace2Nutzer Kernel for codina and codina?

Or what can you recommand for the ace 2 (I have wihtout nfc).

It woould be very cool from you, if you could give links and maybe a short Installation advice :)

Best regards

dxnemesis
[Galaxy Ace II Android Development] supachris:
I recommend the latest version of ace2nutzers CM11, this is Android 4.4.4 and is very smooth and stable. But first, you have to bring up your phone to JellyBean with the samsung update. AFAIK you cannot flash a 4.x ROM over GingerBread. After this you have to root and install temporarely CWM in stock recovery, wipe data, wipe cache, wipe dalvik cache and install the CM11 ROM and GAPPs package.
[Galaxy Ace II Android Development] rezniqsvk:
no change - music is fine but it makes cracking sound in high freq my ear cant stand that sound ( it sounds like "electric shocker?" used to fire up the gas u cook on)
[Galaxy Ace II Android Development] jungp:
Hi fluffi444,

Thanks for this hint. Meanwhile I also think that the internal emmc is dead (see (2)). But before:

(1) --------------------------------------------------------------------------------------------------------------------------

I tried this with R2.10 and then directly booting into recovery after flashing kernel - again cwm-6.0.5.0

and no change. In detail:

dd if=boot.img of=/dev/block/mmcblk0p15

dd if=/dev/block/mmcblk0p15 of=boot1.img (for comparison later)

boot1.img has size 16777216 and orig-R2.10 boot.img had size 5966192

cmp -n 5966192 boot.img boot1.img

boot.img boot1.img differieren: Byte 45, Zeile 1

Question: What is usually on /dev/block/mmcblk0p17 named "Kernel2" ? Can I be sure that the device is really booting the kernel from /dev/block/mmcblk0p15 ?

(2) --------------------------------------------------------------------------------------------------------------------------

~ # mount /system

~ # mount | grep system

/dev/block/mmcblk0p3 on /system type ext4 (rw,seclabel,relatime,user_xattr,acl,barrier=1,data=ordered)

WiFi

I don't know if it's at my end only or not, but after flashing any ace2nutzer's kernel I loose WiFi. Anyone else has the same problem?

ace2nutzer ists viell absichtlich nur weil ich in österreich lebe? ;)
[Galaxy Ace II Android Development] ace2nutzer:
Hey..

if u've working ADB on Linux .. then try this:

unpack my kernel .. an then open an term. emu.. in same folder (press F4) (unpacked .zip)

boot the phone into recovery ... and connect it with your PC and type:

adb push system /system

adb push boot.img /tmp

adb shell dd if=/tmp/boot.img of=/dev/block/mmcblk0p15 bs=4096

after that:

reboot recovery

and check running kernel via:

cat /proc/version

Check the date of the kernel .. if it match with flashed kernel ;)

Disclaimer: i'm not responsible if u'll brick your Phone using this guide.

BETA - Next Version

Hi Guys !!

1. Before i make an official release of the next Version .. i want to be sure that it's stable .. because it's really hard undervolted :o ....

1a. Therefore it's called "BETA" .. it should be fully usable for daily usage .. but as i said.. if it's stable... excepted of this there are no Bugs :)

2. Changelog = i'll write it later on Post #2 in "Next Version"

2a. But i want to mention one new feature :o - Try the CM Performance Profiles :D u'll find: Powersave, Balanced and High Performance :)

And one more Thing: There is no more need to change CPU/GPU/LCD Freq... The CM Profiles regulate it all for u :highfive:

Pls test it and report here your experiences with all 3 Profiles ..... :fingers-crossed: :good:

Testing :)

So far zero problem.

The phone is smooth.

The only app that is slow is facebook
[Galaxy Ace II Android Development] gepel:
After a day of usage i could say that the phone is complete stable and especially the perfomance profiles is a great add.
[Galaxy Ace II Android Development] Alex_Gamer:
Superb! This new version its so smooth I suggest to all users to delete GPU_oc script in init.d for use the performance profiles, and use performance profiles on status bar quick settings tile to have a more faster way to change profiles :D.

And about ram the phone sometimes gone crazy and lag but only sometimes cause I have too much social ram eaters like facebook, I hope we can have a phone smooth although we have ram eaters installed on next releases :)
[Galaxy Ace II Android Development] ace2nutzer:
Yeahh :D:D Sounds great Guys ! :o

Ohh.. i've just forget to mention to delete gpu_oc_ script as @ up say .. no more needed .. also i suggest to disable "set on boot" for CPU OC .. because otherwise the CM Performance Profiles will don't work properly :)

Quick Info what the Performance Profiles do:

Powersave:

CPU: 300 - 600Mhz ; GPU: 0/150/300 - 300Mhz

Balanced: (Stock Freqs & default)

CPU: 300 - 800Mhz ; GPU: 0/150/300 - 400Mhz

High Performance:

CPU: 300 - 1100Mhz ; GPU: 0/150/300 - 690Mhz

btw: For me even with the Powersave Profile the Phone is smooth :o:D

Hi,

I think this is the same what I already did. Only difference that I did this via ADB shell.

Thanks again
[Galaxy Ace II Android Development] ace2nutzer:
I think it's fixed... i've completely reworked CPU / CPU Algorithm ... but without hope .. because i don't have a buggy LCD ...

Now i've tested for me both LCD Drivers .. WS2401 and S6D .. and i had till now never ever no one blackscreen issue .. so it's 100% coming from a crappy Hardware... - So i don't say it's broken LCD if u've this blackscreen .. but something else like incompatibility or what ever ... anyway i also don't say that it'll never working for such "buggy lcds.." but at the same time i can do nothing to fix this very rare bug.. because i don't have such LCD with this issue. Therefore u Guys u can do only 2 Things: just flash always latest kernel here.. and hope one days it's fixed... or sell it on ebay and by another ace 2 .. and hope it's not buggy :o

An other exclusive way is: if somebody has such problem with the LCD Bug.. and u want immediately to fix it, then u can try to send it to me and i'll investigate that curious Problem.. but there i can also not promise that i'll fix it 100% .. but i can try :) On such case pls send me a pm. ;)

But first test this Beta Version .. it seems very good... for it's really stable, smooth and good battery lifetime with my S6D LCD ....

btw: Power consumption on IDLE, screen ON with all 3 Profiles: 91mA :highfive:
[Galaxy Ace II Android Development] ace2nutzer:
Okay.. u can probably forget this Phone... by another Ace2 from ebay.. and sell this as defective on ebay.. or keep it for some working parts :D
[Galaxy Ace II Android Development] MrBlackCore:
Sup. @ kinda stupid questions. First - where the hell can I locate init.d cause for f..k sake I cant find it. 2nd - I set my phone to performance and all is good but when I restart it it reverts all changes... Is this normal?
[Galaxy Ace II Android Development] ace2nutzer:
/system/etc/init.d u can delete all scripts .. excepted 01optimization :)

Yes.. actually it's normal .. that's why alex_gamer suggested to use the quick settings to change Profiles ;)

I'll try to find a way to make it permanently also after reboot.. so actually it's better to don't reboot the Phone :D

Maybe i'll try to provide a init.d script to make a custom profile active by the user .. as simply possible ... (noob friendly :p)
[Galaxy Ace II Android Development] Vexylle:
Well I'm getting rnd reboots after 1-2 mins, i should probably make a clean instal.

But beside that, great work and keep it up ^^
[Galaxy Ace II Android Development] ace2nutzer:
Random reboot even with "balanced" ?!

If yes, u don't need probably to make fresh install.. maybe GPU Freq of 690Mhz is just too much for your Phone ??

And if not, i think this is due to undervolted CPU 300Mhz Step ! Just tell me, then i can upload a kernel with higher voltage for this .
[Galaxy Ace II Android Development] Vexylle:
I'm getting the reboots on power saving, balanced and high performence. Anyways I have those reboots even on the 05.01 kernel version with chronos newest CM 11 build(f2fs). tomorow i'll just do a clean instal and watch how it goes.
[Galaxy Ace II Android Development] Alex_Gamer:
You better use ace2nutzer's cm11 by now, trust me ;).
[Galaxy Ace II Android Development] ace2nutzer:
check for init.d scripts .. u need only 01optimization and don't use Chrono Settings App .. that cause reboots with my kernel ...

Ans viceversa also: don't use NovaThor App with Chrono Kernel :)
[Galaxy Ace II Android Development] Vexylle:
ah chrono app, yeah that's the problem
[Galaxy Ace II Android Development] ace2nutzer:
@ all

so, this Beta Build:

[Galaxy Ace II Android Development] gepel:
Stable for me also, but the perfomance is worst (browsing, games) compare to previous build .
[Galaxy Ace II Android Development] gepel:
You wrote that when we change the perfomance profiles is also change and the lcd_freq. Now im on perfomance profiles and the lcd_clk says "current LCDCLK frq@499.."" Am i missing something ?
[Galaxy Ace II Android Development] ace2nutzer:
@ up

ur're right ! I can confirm Performance is badly.. on some latest builds....

I can to all suggest that build:

20150422

till next Update :)

The bad performance + laggs is coming from some commits .. .. and mostly bad is the interactive Gov.. i don't know what happened.. but it's completely ****ed up ^^ (laggs + battery draining) I'll once again completely rework + calibrate CPU / GPU Algorithm and use Dynamic Gov. instead of interactive .. also update CM11 based on latest Chrono CM11 .:) This is much work, but i'm sure this is worth.. u surely don't believe how great that device can perform. (if it's correctly calibrated) - Of course i'll try to reduce CPU GPU Freq to min. possible without having laggs.

@ Performance Profiles:

i had explained it bad.. i mean u don't need to change LCD Freq because it's already best Value in kernel by default for both drivers ... The Interface has ability to change anyway the LCD Freq just in case if somebody has the Blackscreen bug .... then it can be fixed (maybe) by using lowest Freq ....

On Beta Version.. that do the Performance Profiles:

# CM Performance Profiles
# Powersave
on property:sys.perf.profile=0
write /sys/devices/system/cpu/cpu1/online 1
# write /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor powersave
write /sys/kernel/mali/mali_boost_high 299520
write /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 600000

# Balanced
on property:sys.perf.profile=1
write /sys/devices/system/cpu/cpu1/online 1
# write /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor interactive
write /sys/kernel/mali/mali_boost_high 399360
write /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 800000

# High performance
on property:sys.perf.profile=2
write /sys/devices/system/cpu/cpu1/online 1
# write /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor performance
write /sys/kernel/mali/mali_boost_high 691200
write /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq 1100000

But maybe on next version it'll be different ... ;)

Test Build

Hi @ all

actually i'm still developing for kernel + ROM ..... i'm also trying to make things a bit easier ...

So there is an test build for codina/p Ext4 ... i need to know if it works properly on Codina Device ... here on Codinap it works great... :)

Secondly: There is also the YouTube Fix included (Live Video) and this Kernel works without any issues with latest CM11 ROM from Chrono :o

btw: don't forget to freeze or delete ChronoSettings.apk ... otherwise you'll get random reboot all the time :)

http://d-h.st/J7gI

btw2: this is of course an preview for the next release.. incl. CM11 ..... there is interactive(default) + dynamic gov. included ....

If u had installed Chrono Kernel or just CM11 by Chrono .. make sure that u delete or disable all init.d Scripts ... this Kernel here is coming with only one script: 01_lcd_clock ... and 01optimizations script is moved to ramdisk :cowboy:

U don't need to delete Modules before or after flashing kernel... the updater-script do it for u !
[Galaxy Ace II Android Development] Vexylle:
[MENTION=5840412]ace2nutzer[/MENTION] dunno why but my phone is recognized as Codinap, but it's codina is there a fast fix solution for the problem?^^'

edit: nwm got it with 3parted fixed
