So what should do now to fix low sound bug,i am sure this bug is not in your phone.
[Samsung Galaxy Core.] Ih24n:
Not tested on my device.. Because my device brough by my Father.
[Samsung Galaxy Core.] Y300-0100:
Mtp fixed. Only wpa_suplicant is the problem now.
[Samsung Galaxy Core.] Ih24n:
Yes that is the main problem now... If wifi fix. This CM11 ready to daily use...

And this is all the logcat which I get. And I will upload every logcat here : https://www.androidfilehost.com/?w=files&flid=53106
[Samsung Galaxy Core.] doesntexits:
Did you build bcm4330 as a kernel module?

Also, i've digged your logcat and got this thing

D/WifiHW ( 614): Unable to unload driver module "dhd": No such file or directory
[Samsung Galaxy Core.] Y300-0100:
Hi

I saw that vivalto don't use bin/ wpa_suplicant. When I us wifi stay in turning on state when I remove it I can turn it on and off. Any suggestions regatding that?

logcat without wpa_suplicant:

http://pastebin.ca/3481288
[Samsung Galaxy Core.] doesntexits:
wpa_supplicant is just a binary that control WiFi's behavior. None of SPRD stuffs are there
[Samsung Galaxy Core.] Ih24n:
what name the logcat file which you get that sir?

I add config dhd to "m" . but I not get the dhd.ko in my build environ and my modules folder.

Headset volume is extreme low,i tried to fix by adding mixer_path.xml but LMAO,phone got soundless.

Please if anyone have any idea about this bug.

Your help and suggestions will thankful.
[Samsung Galaxy Core.] doesntexits:
It's CONFIG_BCM4330=m, not CONFIG_BCMDHD=m

Search in "out/target/product/kanas/obj/KERNEL_OBJ" for "dhd.ko" after changing that config
[Samsung Galaxy Core.] Ih24n:
wkwkwk I am false .. I change CONFIG_BCMDHD not CONFIG_BCM4430 :D ... I will try sir.
[Samsung Galaxy Core.] doesntexits:
Remove audio_policy.sc8830.so from /system/lib/hw

[Samsung Galaxy Core.] DarkWolf:
No change in headset sound...
[Samsung Galaxy Core.] Ih24n:

Download beta 1 kernal from link above and flash it.this will fix your file manager issue,

Download from your phone may not work so download from other device and put in SD than flash.
[Samsung Galaxy Core.] revomalik:
you should have read the first post before hand *facepalm*
[Samsung Galaxy Core.] Ih24n:
Read the know issue.

For file manager. See OP. Try the kernel which I attach ...

Headset Bug Very less sound when playing Music on headphone
[Samsung Galaxy Core.] Y300-0100:
default_gain.conf in etc is only config that I can think of gor headphones. I also tested but without gain config and sound is very low.
[Samsung Galaxy Core.] Ih24n:
Yes I know and now searching reference to fix that.
[Samsung Galaxy Core.] Ih24n:
How about logcat?
[Samsung Galaxy Core.] Y300-0100:
I don't

WIFI FIXED!!!
[Samsung Galaxy Core.] Ih24n:
Wifi really fixed? Any clue for me to fix wifi?

For video playing what which you change to make stock player can open 720p video?
[Samsung Galaxy Core.] Y300-0100:
Wifi fix tomorrow. I definitely need sleep. I tested 1080p from yts.ag and it works with stock player. Only issue remain extremely low volume only when playing music with headphones. Good night.
[Samsung Galaxy Core.] DarkWolf:
I had also played video using stock player,some formats are supported on my stock..and ya [MENTION=5985833]Y300-0100[/MENTION],did you said DEADPOOL??that's 18+ lol...hope you will get rid of low headphone volume bug...
[Samsung Galaxy Core.] Ih24n:
wkwkwk ok I will wait.

or can you give me the libwpa_suplicant.so, bin/wpa_suplicant,bin/wpa_cli, bin/hostpad , bin hostpad_cli from CHM which fix on wifi.
[Samsung Galaxy Core.] AnDrOiiiD_YT:
PM me, if you need a tester [emoji6]
[Samsung Galaxy Core.] Ih24n:
wkwkwk ok.
[Samsung Galaxy Core.] Y300-0100:
You are going in wrong direction. Main problem is etc/permission/directwifi.xml

delete it....
[Samsung Galaxy Core.] Ih24n:
This file? android.hardware.wifi.direct.xml
[Samsung Galaxy Core.] DarkWolf:
After deleting this file,atleast i can switch on wifi but next moment it automatically switchoffs.
[Samsung Galaxy Core.] Y300-0100:
Need more modifications for G355H device tree. Can't do it right now. Im not home.

When I get home I will update my sources on github. So ih24n can compare it.
[Samsung Galaxy Core.] DarkWolf:
Wait for next release,its not that easy to port CM to unsupported devices.developers( [MENTION=6737662]Ih24n[/MENTION] [MENTION=5985833]Y300-0100[/MENTION] [MENTION=3901048]@doesntexits) are trying their best to make it more and more stable.
[Samsung Galaxy Core.] Joaquin Scala:
Wifi does not work after removing android.hardware.wifi.direct.xml

I leave my logcat for research

http://www.mediafire.com/download/gdc7ml0p770kbcd/logcat.txt
[Samsung Galaxy Core.] Ih24n:
Can you commit to my github source sir?
[Samsung Galaxy Core.] Ih24n:
Underclock is 200MHZ . And 2,2GHZ?? Are you want youre phone explode?... And very hot like a ember?
[Samsung Galaxy Core.] Ih24n:
Need more configure. Just wait what Me and [MENTION=5985833]Y300-0100[/MENTION] do.
[Samsung Galaxy Core.] Y300-0100:
I will see what I can do because I don't use any patches. I fork sprd implemented stuff from vivalto team.
[Samsung Galaxy Core.] Ih24n:
I only need/know what which you do to make wifi fix and 1080p video fix :D
[Samsung Galaxy Core.] doesntexits:
Those are hardware stuffs, which are for fixing video codecs at most, and some for RIL

The WiFi works by default with us. And btw, I got clickbaited your donate button :D
[Samsung Galaxy Core.] Y300-0100:
yeah I know.

And thanks for donation I think that you are first who donated for my hard work. :D
[Samsung Galaxy Core.] Y300-0100:
For testing purposes because I can't push commits to Ih24n than easily I will build test cm for kanas3gxx (SM-G355H) and post it here if [MENTION=6737662]Ih24n[/MENTION] won't mind.

ps. I'm preparing device tree for kanas3gub (SM-G355M) to. If someone have problem with that let me know otherwise click thanks or donate to me :D
[Samsung Galaxy Core.] Ih24n:
I get it . I try compile with compare youre source now :D.

[MENTION=6737662]Ih24n[/MENTION] & [MENTION=5985833]Y300-0100[/MENTION] okay will try it now

---------- Post added at 08:00 AM ---------- Previous post was at 07:38 AM ----------

Assert Problem... Going to remove the assert lines in updater-script and try it again

Working now:

- WIFI

- Video recording

- Microphone

- Calling

Not working:

- MTP

- Root (from the Developer Options)

- GPS Toogle in Status Bar: Doesn't react (but works in Settings Menu perfectly)

- Dual SIM
[Samsung Galaxy Core.] Y300-0100:
I will fix ota asserts. I just have to add:

# Assert

TARGET_OTA_ASSERT_DEVICE := kanas3gxx,SM-G355H,kanas,SM-G355H

like [MENTION=6586967]doesntexits[/MENTION] suggested.

every thing ok? camera, calling etc..
[Samsung Galaxy Core.] doesntexits:
Umm... seems OK, but you've to get sth for dual-SIM. In build.prop:

persist.radio.multisim.config=dsds
[Samsung Galaxy Core.] Y300-0100:
Yes, you are right but since I rebase devices smg355h and smg355m and build roms in one night it's not surprise that I missed it. I will push devices tree with local_manifests to my github so that Ih24n and you fix it because I don't own dual sim phone and no sure what to change.

regards.
[Samsung Galaxy Core.] doesntexits:
Changes for dual-SIM are in patches folder

Now is [MENTION=6737662]Ih24n[/MENTION]'s part. IDK why his ROM doesn't have HW rendering enabled
[Samsung Galaxy Core.] Ih24n:
Ok now wifi fix... :D
[Samsung Galaxy Core.] Y300-0100:
for some cm reason it's doesn't come rooted

MTP not working when you go to storage settings and tick use as MTP?

nothing happens?

for gps in status bar I have noticed.
[Samsung Galaxy Core.] Ih24n:
Yuph In my previous build is have some issue on hwrendering ... But i try with new source sync and patch again and now in the progress to compiling... And lets see what hw rendering still isue or not...
[Samsung Galaxy Core.] Y300-0100:
Changes for dual-SIM are on [MENTION=6737662]Ih24n[/MENTION] now. Regarding HW rendering I think that he doesn't use your modified sources from you with sprd stuff as I did and I didn't look to much at his configuration but I think that we made huge progress in one day :)

---------- Post added at 11:11 AM ---------- Previous post was at 11:03 AM ----------

take a look at my local manifest regarding HW rendering I also had to made some changes when I fork it from [MENTION=3622245]doesntexist[/MENTION] .

vivalto:

TARGET_BOOTLOADER_BOARD_NAME := SC7715T

kanas3gxxx:

TARGET_BOOTLOADER_BOARD_NAME := SC7735S

PS. later I will upload clean devises tree with dependencies and patch your kernel.

now I don't have free time
[Samsung Galaxy Core.] doesntexits:
Haha, i mistyped the "doesn't exist" word, and it's "doesn't exits" :D

Because that account is exist, so i've to change to another one. Gotta call mods when having time
[Samsung Galaxy Core.] AnDrOiiiD_YT:
My phone freezed after ticking that. I removed battery and turned my phone on. Then my phone didn't past the galaxy core 2 splash screen. I factory resetted via recovery and then it freezed on the cm11 boot animation... :rolleyes:

Going to clean install cm again...

Edit: ADB is causing that. I connected my Phone to PC. My PC recognize it. But gives me ADB error (running Ubuntu). When i go to Developer Options and disable ADB my phone freezes and the same story happens...

Let's make a gitter group. It will be much easier to chat...

Edit 2: Everytime I untick ADB my phone freezes and it don't boot anymore.
[Samsung Galaxy Core.] Y300-0100:
For me no issue there. [MENTION=6737662]Ih24n[/MENTION] has to take it from here. I have done all I could. Probably some changes in root dir folder.
[Samsung Galaxy Core.] Ih24n:
I use old sprd stuff (base . native. Hardware.hardwere_legacy) .. And today I redownload from [MENTION=5985833]Y300-0100[/MENTION] . :D .
[Samsung Galaxy Core.] doesntexits:
If you guys want some SPRD stuffs, they're all here : https://git.mozilla.org/?a=project_list;pf=external/sprd-aosp

We cherry-picked changes from them, and get it to our ROM, so it's stable
[Samsung Galaxy Core.] Ih24n:
Hihihi maybe because I use old sprd stuff from [MENTION=6586967]doesntexits[/MENTION] I now use youre [MENTION=5985833]Y300-0100[/MENTION] ... And maybe CM11 will ready to daily use :D .
[Samsung Galaxy Core.] AnDrOiiiD_YT:
To fix GPS Toogle:

Settings>Notification drawer>Quick Settings panel>Location modes: Select the modes you want to use/toogle, and it's fixed!
[Samsung Galaxy Core.] Ih24n:
Wow a lot of sprd stuff :D . Thank you sir .

MTP works greatly for me on my both ubuntu 15.10 and windows 7&8.1,also i can toggle GPS through statusbar,dont know how to fix low headphone volume bug.
[Samsung Galaxy Core.] Ih24n:
Ok get it And I will compile again... :D ..
[Samsung Galaxy Core.] doesntexits:
You only get low UI volume or even listening to music?

Another thing is: Please post logcat for these such logical bugs
[Samsung Galaxy Core.] AnDrOiiiD_YT:
Kernel has Problems... :(

My Phone gets always hot (stays at 1200/1300Mhz :(

PS: I don't have another App installed to Clock CPU
[Samsung Galaxy Core.] DarkWolf:

[Samsung Galaxy Core.] FedericoPeranzi:
[MENTION=5985833]Y300-0100[/MENTION] Thanks bro, when i get home i going to test it
[Samsung Galaxy Core.] FedericoPeranzi:
For MTP fix just install other file explorer, like root browser, and delete the CM file manager, and the problem it's fix
[Samsung Galaxy Core.] Y300-0100:
It's kernel issue. My CPU spy:
[Samsung Galaxy Core.] FedericoPeranzi:
[MENTION=5985833]Y300-0100[/MENTION] My pc didn't recognize the phone in MTP

Edit:

Wifi works, but MTP don't, everything else works, except for the headphones sound
[Samsung Galaxy Core.] Y300-0100:
Try to take logcat using terminal on your phone:

su

logcat > /storage/extSdCard/logcat.txt

And than plug your phone in PC couple of times.

And your logcat.txt would be in your external SD card

That should help to find issue.
[Samsung Galaxy Core.] FedericoPeranzi:
Oh i Just reflash the stock ROM, wait in a few minutes i going to re install CM11 and give the LogCat
[Samsung Galaxy Core.] Ih24n:
I am not get it...

[MENTION=5985833]Y300-0100[/MENTION] can you see my kernel repository and any else which make the cpu clock like that??

But that happens only sometimes. After I removed battery and let it some time off (the Phone was really hot, ~35°C. I powered it on and clicked many times minimal CPU frequencie at 200Mhz, then it went good.

Would you also like to get a logcat of that and the MTP?
[Samsung Galaxy Core.] Ih24n:
For MTP need disabled MTP cinfig in kernel config... I do that like [MENTION=6586967]doesntexits[/MENTION] said and MTP work... Wait until this compile done.
[Samsung Galaxy Core.] DarkWolf:
[MENTION=6737662]Ih24n[/MENTION]

Can you fix that low headphone volume bug in ROM?

---------- Post added at 11:58 AM ---------- Previous post was at 11:56 AM ----------

Yeah it worked..Thanks
[Samsung Galaxy Core.] Ih24n:
For now no idea how to fix low headphone. Need experimenting
[Samsung Galaxy Core.] DarkWolf:
as other testers said,MTP now not working,i changed multi sim slot count to 2 from 1 but still single sim.

Now after these bugs blah blah blah,

I want to ask a little question

You told that you was working on CM12 too but was not booting up,so what is CM12 status now?
[Samsung Galaxy Core.] Ih24n:
Add this on build.prop

persist.radio.multisim.config=dsds

I am compile temasek CM12 but only show bootanimation very long long long long and long time but not enter tto home.
[Samsung Galaxy Core.] DarkWolf:
One day you will succeed on CM12 and im gonna wait...
[Samsung Galaxy Core.] Y300-0100:
[MENTION=6737662]Ih24n[/MENTION]

You will have to deal with dual sim issue.

Now when wifi and low volume bug fixed.

I have already fix mtp for SM-355M and tomorrow I will fix it for SM-355H and I don't want to patch my sources for dual sim. As I can see both model are dual sim ???
[Samsung Galaxy Core.] doesntexits:
SPRDRIL already supported ds. The one thing to patch is system/core. It has missing "system" user for init to set "ril.sim2.present=1" on DS model. Else you can enable DS thru build.prop right?
[Samsung Galaxy Core.] DarkWolf:
If you can fix low volume bug,that will great..
[Samsung Galaxy Core.] Y300-0100:
Patching system core wont afect buildig for single sim?

And build prop could you send me example.

ps low volume is alredy fixed but I can't build that fast.
[Samsung Galaxy Core.] doesntexits:
Yes, it doesn't harm anything for single-SIM phone. It just adds the "system" user for ril property request, so in case, our GV has to set "ril.sim2.present=1" on init with "system" user but it fails before, now success
[Samsung Galaxy Core.] Ih24n:
[MENTION=5985833]Y300-0100[/MENTION] i done fix mtp and will upload in this night... Only low headset now the issu in my new build.
[Samsung Galaxy Core.] Ih24n:
Use fix both sim in OP will fix it.. And add on build.prop persist.radio.multisim.config=dsds

But In mynmind SM-G355M can use this CM11 no need spesific CM11 ...
[Samsung Galaxy Core.] Y300-0100:
let me be easy only 5 files:

https://github.com/Y300-0100/propri...mmit/1b4844b7d5ee67772511e5ad4d4024a41e6c370c

unzip your rom , replace this files, zip rom again, flash and miracle!!!

don't forget to say thanks :D
[Samsung Galaxy Core.] Ih24n:
This is for fix low headset sir??
[Samsung Galaxy Core.] Y300-0100:

YouTube only runs 360p (already tried DPI to 200)

Home button does not work (worked on beta 1)

Can't install Xposed

These are the top 3 things I use.. PLEASE FIX!!! :(
[Samsung Galaxy Core.] doesntexits:
YouTube doesn't show 480p option on 4.4.4, so it's a glitch, not a bug. Just change Android version in build.prop to 4.4.2 then it works

Same as Xposed too. It has some compatibility issue with 4.4.4, so use this instead (from attachment) thanks to [MENTION=260994]SolarWarez[/MENTION]

Dual sim

The dual-SIM mode may not have worked because maybe you have used the SM-G355H kernel that is single-SIM. I read that for dual-SIM devices a specific kernel is necessary for them.

http://opensource.samsung.com/reception/receptionSub.do?method=sub&sub=F&searchValue=SM-G355

This link has the kernel for SM-G355H
