@up

welcome back ! ;)

this is hardware issue, u'll need to replace your LCD.

Try with temp cwm6028 to flash latest CM11.

if it doesn't work, try many times to reboot to recovery till the LCD works properly.

if after 20 times, it stil doesn't work,

then just boot to download mode even if u can't see anything, and flash ODIN Kernel u can find in my Dev-Host !

After that, it should reboot itself, then u can see if it works better or not.

IF u still can't see anything, then it looks bad ... and it's just too much damaged, then even some Software tricks can't help.
[Galaxy Ace II Android Development] Kurajmo:

Ok, editing updater script with Notepad++, removing the txt extension, replacing the tee folder and archiving the main folders with 7zip makes the new test ROM install.

[MENTION=5840412]ace2nutzer[/MENTION] Tested test build 160927 with all my apps, including Google Maps (which gave a lot of issues with GCC 4.8 instead of 4.7 if i remember correctly), Spirit FM Unlocked and TrackID. Perfect. Google Images still not working properly though.
[Galaxy Ace II Android Development] ace2nutzer:
Thanks for testing ! I was just wondering that all worked fine for me with GCC 4.8.. so now for u it's working as well without any issues... except of Internet images. Well, then i'll add even more optimizations and next days i can make a release.

Really can't understand why it's working now :D In the past many times i tried, but it never worked properly.

Actually also tried with GCC 4.9, but it gives Build error. Maybe one day that will work too lol :)

btw: u can stay on that test-build, it should work stable ... if not, just report here.
[Galaxy Ace II Android Development] shaqman89:
If it has existed for months, then it means most of us must not be using it then :D

Well, I don't think it's high priority anyway since I usually use wifi tethering, and that works flawlessly. It just happened that yesterday I was low on battery, and since I was already plugging it to my laptop, I just thought of using it.
[Galaxy Ace II Android Development] Dr360r:
Actually, USB Tethering (of a WiFi router; however i stopped using WiFi for the computer connection since i laid Ethernet cables) is working for me. Windows XP Professional 32 bit, Samsung USB drivers installed. ROM 160910, Kernel 160910.
[Galaxy Ace II Android Development] ace2nutzer:
Yup, same here :) works instantly. I've connected the USB Cable, i tap on quick settings to Tethering and immediately i've internet access on my laptop. [MENTION=5701712]shaqman89[/MENTION]

Tested with USB config: Mass storage ... (but not enabled)

Maybe u was using MTP or ADB service was enabled ? - Need tests if it works as well !
[Galaxy Ace II Android Development] Dr360r:
I'm using MTP, since i can't make mass work on my Windows XP Pro computer (but it works on my Windows 7 equipped laptop). ADB off.
[Galaxy Ace II Android Development] shaqman89:
Strange. It still doesn't works for me. I changed between MTP, PTP and UMS, and no changes.

I tried also killing adb (adb kill-server), but it didn't help.

MTP, PTP, UMS and adb also works fine though. Does usb tethering uses a different driver than those 4?

The only thing that is different that I could think of is that I am using Windows 10.

I'll try it out later on another computer whether it's an issue only at my laptop.
[Galaxy Ace II Android Development] ace2nutzer:
I think it's a driver proplem .. I'll check which driver is needed for that.
[Galaxy Ace II Android Development] shaqman89:
After testing it a bit more, I could do tether on Windows 7 boxes (didn't try Windows 8), but none of the Windows 10 boxes I tried could do a USB tether. In that case, I think the issue is not with the ROM or kernel, but rather in the latest windows.

CMIW

Thanks :good:

Try to install this kernel:

http://www.xda.mister-freeze.eu/XDA-files/ace2nutzer/misc/

btw: it has nothing to do with the temp. .. it's just a defective LCD Chip.. when the Screen is off for long time, then it can't wake up properly .... u can try probably to use different LCD Freq's and video.modes .. if it helps ... for some, such tricks can help... but it's very high time consuming till u'll find the working config. Also u can try different screen ON/OFF delays .. this also will affect such behavior with wake up issue, grey lines, screen blinking etc .... but as a said it needs a lot of patience and time.

And on my kernel if u want to change delays, u've to rebuild the kernel, so u can't, But the other things, u can try.

If i remember correctly chrono kernel has the ability to change LCD delays over an interface, so on the fly.

U may can find with chrono kernel a working combo of delays for your LCD, then u post it here, and i can build the kernel with such config only for u,,... nobody else can use it. Other than that, i can't do anything for your LCD. So i repeat again, it's hardware failure, but with some luck and patience u maybe can work around this with Software tricks .....
[Galaxy Ace II Android Development] ChronoMonochrome:
Not supported anymore for the most of the display waking delays, since this code was bugged (well, I think, it's a matter of a wrong delays configuration, anyway I was tired of searching for anything better than the stock one, so just reverted these changes).
[Galaxy Ace II Android Development] Kurajmo:
I don't see anywhere this LCD Delay.

I search everywhere. Screen option, novathor setting app, performance option, developer option. No luck with that.

Now I flash (again and set up every app with that) newest cm 11, gaaps, chrono_kernel_r2.24.7

Because when I try flash only kernel. Then cm have a bootloop.

Eeh finally everything works now.

Normal temperature when I use phone.

No black screen bug for now.

I have only 1 reboot when I try change wallpaper.

And WiFi stuck on turning on.

But after I restart phone back to normal.

I have a hope. Now everythings works good without issues.

I don't have a time to flash again.

Just need stable phone.

Never mind thanks for all help.
[Galaxy Ace II Android Development] ace2nutzer:
u've to search in /sys/kernel/* or /sys/module or /sys/devices/pri_lcd* for any "delay" interfaces.

Also it's only available in certain chrono-kernel versions ... (old builds) if u're interested, u can read changelogs and find such builds that have this feature built-in. - Otherwise if u didn't understand anything what i wrote, then just forget it ;)
[Galaxy Ace II Android Development] dixee:
no, you must enter recovery mode. I mean that you can flash rom and then Gapps in the recovery mode at the same time.

[MENTION=5840412]ace2nutzer[/MENTION] I have a problem with pattern lockscreen. sometime when I tap to draw for the correct pattern, rom can't read my pattern correctly, but I'm sure I'm using the right pattern.

In this case, I should restart the phone, then I can draw the pattern and rom can respond correctly. how to fix this?

fyi, I'm activated slide to wake, double tap 2 sleep, and using 1000Mhz proc frequency and using the latest cm11 from your build
[Galaxy Ace II Android Development] ace2nutzer:
dunno, i don't have this issue.

Did u also tried with clean installation ?
[Galaxy Ace II Android Development] Neo~TheChosen:
The best custom rom I've ever used but I cant type in numbers during calls? How can I fix this problem? or can I change current dialer via root access?
[Galaxy Ace II Android Development] ace2nutzer:
Did u changed the Animation speed in developer-settings?
[Galaxy Ace II Android Development] Neo~TheChosen:
Nope I did not change anything.Also screen goes black during call,and does not show up until I plug in earphone.And when call screen shows up,buttons on dialer dont work(cant type in numbers,cant end call cause when I touch the buttons they are not responding).
[Galaxy Ace II Android Development] ace2nutzer:
During a call the screen is black, (normal behavior) but when the phone is left from the ear, then it should automatically turn on the screen, so that u can end the call, if it stays black, then there is a hardware issue with the proximity sensor ....
[Galaxy Ace II Android Development] Neo~TheChosen:
Still black when the phone is left from ear.So turned off sensor.But dialer still is not responding during calls.Cant type in numbers,and can not end call.Should I re-install or not? I went back to stock JB now.
[Galaxy Ace II Android Development] ace2nutzer:
yeah, try a clean installation. But how did u disabled the sensor ? - Really don't know ....

If it works fine with stock jb, then it should work as well with CM11.
[Galaxy Ace II Android Development] Neo~TheChosen:
Sorry I disabled proximity sensor on stock rom JellyBean,not on CyanogenMod.Can we disable sensor on CyanogedMod? Btw can u type in numbers during calls? And as I said before,even if the phone is left from the ear,still screen does not show up.How can I solve these problems? I need this rom cuz stock rom sucks..
[Galaxy Ace II Android Development] ace2nutzer:
How ? - Can u post pls an screenshot about that setting ?

Actually don't know ... try to search it on /

Yes :)

.

Here it works just fine.

During a call try to play with the proximity sensor ... it's on the right edge beside the ear-speaker, there just press the screen ... but make sure to don't cover the sensor, otherwise the screen stay black. If u can see that the sensor works properly when u hold and press the right edge of the screen, then it's just a bad contact (circuits) of the sensor. Try to open the Phone and repair it, if u're able to do that.

Nope, Stock ROM is fine, only Stock Kernel + build.prop sucks ;)
[Galaxy Ace II Android Development] Kurajmo:
I have last question about this rom.

Maybe someone help me.

As you can see this is all partition on my Galaxy Ace 2

Yesterday and today I downloaded some music games like Dynamix etc.

I can see my memory for install apps dissappear quick.

I have old Toshiba 16gb class 10 memory card.

With music etc.

Is there any way to use all of this Toshiba card as full memory to install any app from Google store?

I mean I want use Toshiba card with CM11 and chrono kernel.

Is this possible?

Any help?

I have really fun when I play Dynamix, and I see other rhythm games exist.

But memory with this phone can't handle big games (1gb +).

And one other thing.

Almost one week when I clean install CM11 and chrono kernel.

I don't have any black screen issue. Magically dissappear.

Good work Ace2nutzer

And thanks for this rom

I dont think I am able to repair phone myself.I would only make it worse lols..

Can u suggest any good kernel for stock rom? (Only kernel not rom)

Btw keep up the great work.Best rom!
[Galaxy Ace II Android Development] Kurajmo:

OTG.TEST Kernel is Up !!!

Hi Guys,

i've compiled an OTG Test Kernel ... pls test if OTG works or not, test all your USB Devices ... such as Card Readers, USB-Flash Disk etc...

And report if at least one Device is working properly :)

I remember CK have an interface to disable proximity sensor since his is also broken.

Would it be worth it if your kernel to also have this interface?
[Galaxy Ace II Android Development] Kurajmo:
Good God. For this moment I don't have adapter to do this. But if I have I test my Adata 16gb USB 3.0 pendrive.

Good to hear someone work on otg functionality.

This is very useful (playing emulators etc).

[Galaxy Ace II Android Development] ace2nutzer:
Yeah, but only USB 1.1 and USB 2.0 is supported.
[Galaxy Ace II Android Development] Dr360r:
Would be really nice if the phone could also be compatible with an USB to RS232/422/485/J1708/CAN serial port converter, so you can also program PLCs, command devices or take readings with the Ace 2 and a terminal emulator.

Unfortunately i don't have a micro usb to female usb port adapter at hand, so i can't test OTG.
[Galaxy Ace II Android Development] dimon130:
The algorithm checks OTG? What should be included in the NovaThor?
[Galaxy Ace II Android Development] ace2nutzer:
If i'm not wrong it's already enabled in kernel configuration, but to use it effectively there is first needed that the USB Chip acts as an HOST Device ... that's why u guys should test OTG.

Theoretically every USB Device should work, .. the USB Port on the Phone provides up to 500mA output current.

(and maybe possible to increase it), that means u can even connect a HDD ... if 500mA is enough... if not it just needs external power for the HDD.

Yeah, i also don't have an OTG Cable .. that's why i'm asking u all.

Nothing ! - Don't enable OTG on NT-APP ! - This only enables output current on the Micro usb-port ... nothing more !

So just flash OTG.TEST Kernel from FTP "misc" ... and connect OTG Cable with the Phone and connect any USB Device u want ... (test them all) .. if at least one device will work, then we've working OTG on Ace2 ... if no one will work, then we can it completely forget. - Some Guys says that codina hardware don't have proper OTG Support because of the Board Revision.

So why i compiled OTG Test kernel ???

Sony XPeriaU has official OTG Support ... and the Board is also like here on Ace 2 ---> U8500 / ux-500.

So i've compiled the OTG Kernel with same OTG Options like the XperiaU Phone ... so this time if it'll not work, then we can completely forget it.

Please share this OTG.TEST Kernel in all other Forums u're member. .. and report here what other Guys says over the OTG Functionality.

When we've enough reports if it works or not, then i can upload new ROM + Kernel ... a lot of improvements on coming Release !
[Galaxy Ace II Android Development] shaqman89:
I know that USB3.0 or 3.1 aren't supported but since those are the ones I have around, I tried to give it a go.

So I have two flash drives, none are 2.0 devices but since it is compatible with 2.0, I thought it might at least gives something.

After flashing, I tried both devices using OTG but no reaction was given at all (not even flashing leds on the flash drives).

So, I tried to enable the USB-VBUS power via Novathor app and the flash drive leds flashed twice before turning off. When this option is on, the battery indicator shows that it is charging (though obviously it is draining power). This is nothing new though, I had noticed this happened before since I found the USB-VBUS power option.

I then proceed to download USB OTG checker (https://play.google.com/store/apps/details?id=com.app.usbotgchecker). It does confirms that the kernel is OTG ready, but it couldn't detect the device.

Also I would like to ask, do you know, why gallery is not able to run gif's ? I have few gif files in my phone, and seems like galery supports gifs, shows "play" icon in the middle, i click it and it just shows the thumbnail, doesnt show all frames, only the first one. Do you know if thats a gallery issue and i must use external gallery, or it is fixable? Thank you!

as for Gif's, really don't know ... u may try again with next release... maybe works.

If not, just use 3rd-party gallery app from Store.

Anyone has this "issue" that after rebooting device, can't turn off screen with power button for like 10 seconds. I can click a lot, but screen will not turn off, just after 10 secs it comes responsible again. But when i long click power button it opens me power menu, so power button works, just some small issue eith turning off screen. Though, i van live with this, just want to make sure if thats just for me or other peoplr faces this issue aswel. Thank you!

[MENTION=5840412]ace2nutzer[/MENTION] BTW do you know if bluetooth controller connecting with our device works? Because i have ordered ipega pg-9021 controller and it says that it works only for bluetooth 3v and above, and our device exactly has bluetooth v3, so i tried connecting controller, and it does not connect to my galaxy ace 2. But tried on my sisters galaxy s4 and it works. I would try swapping to stock rom, but thats a lot of work for me to wipe everything and reconfigure my device again. Thanks again :D
[Galaxy Ace II Android Development] ace2nutzer:
Screen off: normal, it's loading System files.

Bt controller: i'll check if i can enable some support.

As for otg: nobody is willing to test ?

I need at least one more report, then i can compile kernel with usb host mode, instead of both host + peripheral. Just to see if it works at all. Because we've proper otg chip on our board inside. I suspect that Samsung just blocked something on Software or Hardware side in order to make otg not working, since it's a low-end phone.
