I found some bugs and few fixes which makes this ROM "beta" instead of "stable".

1. Developers option when turned on, cannot be turned off. If you do it, phone freezes, and if you force reboot it, it never gets past splash logo. You need to re-flash the phone again with cm 11 rom.

2. When phone turns on and you try to unlock the phone, the starts vibrating until phone gets unlocked. After I lock the phone and try to unlock it again, it does not happen.

3. The ram usage is too high. Very few apps (freshly installed cm rom) and it still consumes lot of ram. I guess there is a memory leak somewhere.

4. When advanced reboot is turned on from developers option, you can't soft reboot, reboot to recovery, and reboot to bootloader... The reboot dialog stays on screen forever making phone to stay useless until force reboot, but it got fixed when I installed latest busybox.

5. Now, xposed framework. When I install xposed framework, it can't install it's xposed framework libraries, it just fails there. So, exposed framework does not work.

6. No support for moving apps to sdcard... That's something very important.

7. Using sandroid customisations, you can't get network speed meter on status bar. As it never works, no matter what you try.

8. ART does not work, when I tried to turn on ART phone restarts and faces bootloop. You then need to reflash or factory reset using recovery.

9. The battery stats from settings does not show which apps uses the % of battery. But it only show which hardware used % battery.

10. Our phone does not have backlight in it's buttons, so you should remove illumination of hardware buttons option from settings.

11. My opinion here: Profiles and Cell broadcast are not used anymore, they are just obsolete according to me. Nobody would mind if you remove them. Although you should remove them if they also consume memory.

Features Request:

1. USB OTG support for connecting various USB devices like, memory card readers, flash drives, hard disks (if possible), mouse, keyboard etc.

2. Chroot support for booting other linux distros.

3. NTFS support for memory card. As you can't store files larger than 4 GB on memory card formatted with FAT32.

4. EXT2/3/4 support for memory card. These file system are way better than FAT, FAT32 and NTFS.

I'll report more bugs if I find them.

Try out different version of TWRP(my friend had problem with v3.0.0.0 so he flashed with v2.8.5.0 and it worked)

---------- Post added at 07:28 AM ---------- Previous post was at 07:23 AM ----------

Okay which bugs you told,not of them is on my phone..everything is working fine

Yes there is not move to sd option available because CM developers have removed that from CM11 so you will not get that

I have lots of apps but phone uses hardly 60% memory for me..and with greenify it comes to 37%.

OTG is not supported by device hardware
[Samsung Galaxy Core.] ItsMeShouko:
I started out with freshly installed stock rom... These bugs are present even after flashing again, Wiping Cache, Dalvik...

Btw, if you know how the kernel works you can get OTG running on this device.
[Samsung Galaxy Core.] doesntexits:
Speadtrum has its own USB OTG driver, but it's highly broken. We can port it, but as now we don't have time for it

USB OTG also depends on hardware too. If the voltage is not being controlled well, there's high chance that overvolts the phone, may cause permanent damage (because the phone can't be the power source for OTG, so an external power cable is needed)
[Samsung Galaxy Core.] gnumerator:
DC external power supply

And what if the external power source is an USB DC Powerbank?

5V DC cannot overvolt the device I assume, because its the standard USB power output.
[Samsung Galaxy Core.] doesntexits:
Yes, a PowerBank can't overvolt the device, but here I mean that device raises the voltage up unexpectedly if not being controlled well by the kernel, if the phone is using other external power source for USB OTG such as an USB charger
[Samsung Galaxy Core.] ItsMeShouko:
I don't think it would fry the phone. Other phones also handle the OTG with a standard battery without external power source.

Btw, SuperSU binary problem got fixed when I flashed latest supersu from chainfire website. After that I updated it from playstore, and binary updation was successful. There was some problem with SuperSU flashfile (maybe it was too obsolete) by StratOS_HTC
[Samsung Galaxy Core.] doesntexits:
Well, at that side then the phone is only be able to mount an USB stick :D. A hard drive would need at least 10-20W to run, and that's too much for a small phone like Core 2 :D
[Samsung Galaxy Core.] limjh16:
If I'm not wrong it not allowed on xda.

---------- Post added at 03:55 PM ---------- Previous post was at 03:42 PM ----------

Anyways OP, Could I ask if wifi is fixed for this build, as in the github device tree

and I'm looking to get a new ROM.
[Samsung Galaxy Core.] just-a-geek:
Got stuck at cm logo!

i followed all the steps correctly but i got stuck at cm logo. :crying: It keeps on going round n round for long time. I waited for nearly 45 mins. I tried flashing the rom through both cwm n twrp but no luck. Help me out.
[Samsung Galaxy Core.] ItsMeShouko:
Well it would be good if we can mount USB flash drives?. Also if someone can teach me a way to compile CM 13 or am easy way to port, I can start porting. I have CM 13 source.
[Samsung Galaxy Core.] dhiru1994:
status 7 error while installation CM11

Status 7 error while installation of CM11

Installation aborted...

What i have to do?
[Samsung Galaxy Core.] limjh16:
No easy way, in fact a lot of hard work needed to bringup the source to LP, much less MM.
[Samsung Galaxy Core.] Nexxit99_Gaming:
Try this it might work. Restore the stock ROM back again, and then install cm 11 and see what happens. If that doesn't work try formating your device on stock ROM ( it won't format your SD card ) and then install cm 11 and see if it works or not. :)
[Samsung Galaxy Core.] ItsMeShouko:
Why don't we even start?
[Samsung Galaxy Core.] limjh16:
Because we don't have knowledge on this subject and cm11 isnt even done w/o bugs.
[Samsung Galaxy Core.] :
As posted above Lucky Patcher is banned on xda, I know it can be used for odexing apps and add blocking but it is considered warez so try not to discuss it on xda please

Many Thanks

If you are talking about LP, that guy actually meant Lollipop.

---------- Post added at 01:04 PM ---------- Previous post was at 12:57 PM ----------

This rom dev said that he got the source of CM 12 or 13, he said that he can port them to this device but the bugs in CM 11 will also get included in CM 12 or 13. So, he said that he will fix the bugs first and then bring CM 11 or 13 to this device. If I were in his place, I would have started porting and big fixing right from CM 13?
[Samsung Galaxy Core.] limjh16:
Well if you don't even get cm11 bugfixed, then it'll be even worse on cm12.1 or cm13. More wierd bugs pop out. BTW getting the source of cm13 isn't a major step it's simply repo init and repo sync. And if you want to go ahead with cm13 and leave this with all the bugs remaining, you'll have to wait till u finish cm13 to leave ur current buggy cm11. Just my own thoughts, if you want to start you can create a local manifest and start adding in all the repos. If you need a tutorial, google "ROM building from source to end" I'm on phone can't link
[Samsung Galaxy Core.] Nexxit99_Gaming:
Hey guys I have found a mini-bug, the bug is when I download an apk it shows it in the notification drawer like normal but when I click the apk in the notification drawer it says "can't open file", but when I go into the file manager app and click on the file it can install perfectly. I am not sure if this is supposed to happen or it was just a bug.
[Samsung Galaxy Core.] doesntexits:
Well, CM12 API is totally different from CM11, not much things are kept, and so on with CM13. The whole core system of CM13 (system/core) are changed. With ourselves, as we already have CM12.1 stable now, we know what makes it bootable is SELinux, now in CM13 is different. Userspace security API has been changed, which needs tons of patches to make it work with our kernel. So the Core 2's chance for now is CM12.1 at last. You'll still happy to use Lollipop with a cheap phone, also a great archieve of devs

Also about bugs, you'll need to have computer language knowledge to "port" the codes, fixing bugs easier
[Samsung Galaxy Core.] ItsMeShouko:
It was difficult to download very large source due to low bandwith and less data allowance. Since I have my exams this month. I'm surely gonna try building rom next month. Btw, the device tree and other repos by this developer are obsolete on github. It will help others if he updates them.[emoji3]

---------- Post added at 01:45 PM ---------- Previous post was at 01:41 PM ----------

I didn't knew about these differences. Although I have knowledge about Linux and programming. The thing is why don't we collaborate on building the rom? We will surely make great rom.[emoji4]
[Samsung Galaxy Core.] durbaca:
some bugs that i find.

1) Youtube is locked at 360p (Fixed by editing the build.prop file replacing 4.4.4 with 4.4.2 (ro.build.version smth like that i dont remember)

2) The stock browser cannot display video ( wt fullscrenn activated)

3)GPS Not working i tried in a very clear area but i cannot get any signal.

4) The browser is crashing when a site is not having a secure certificate.

Thats all .

Great job with this rom and we wait for that cm 12.1 .

Kepp it up.

Hi all

Hello, I have the sm-G355M and I installed this rom ...

First thank you very much for this great contribution and I hope this rom evolve to perfection ....

Second, Reporto overall performance of the ROM, another unexpected shutdown ....

to install SwiftKey wassap the play store is closed, leaving it in usable, uninstall the SwiftKey and quite normal .... very good consumption ram, memory and battery .... well.

one thing. as my cell is a single sim, but the rom is for two sim device but has not been a problem, and it only comes sim1 ....

sorry my inglish... google traductor....
[Samsung Galaxy Core.] Nexxit99_Gaming:
Hope we get cm 12.1 on this device it would be great !
[Samsung Galaxy Core.] Nexxit99_Gaming:
I found another mini-bug guys, when you turn off the screen there is a noise but the problem is that the noise does it 3-4 times when it should do it once .
[Samsung Galaxy Core.] ItsMeShouko:
I prefer AOSP and CM because they provide Vanilla Android UI. I don't like Touchwiz UI as it's quite bloated and laggy. So, this CM 11 is great on this device. Hope we can soon get CM 12 or 13 ?

---------- Post added at 08:58 AM ---------- Previous post was at 08:55 AM ----------

I haven't faced this bug until now. Can you explain in details or steps. How to produce this bug?
[Samsung Galaxy Core.] Nexxit99_Gaming:
Wait for your phone to turn off by itself and the bug should happen

---------- Post added at 10:14 AM ---------- Previous post was at 10:13 AM ----------

I totally agree with you touch wiz is right mess!
[Samsung Galaxy Core.] ItsMeShouko:
I am using this rom since last week, my phone never turned off automatically. Although my phone switched off regularly when I was using stock rom. But my phone's battery was loose. So, I tucked a piece of paper to make it tight?
[Samsung Galaxy Core.] Nexxit99_Gaming:
NO NO NO I'm talking about your screen sleeping you know after a certain time eg. 30 seconds of inactivity lol. BTW I found another weird thing/ bug can't sign in into cyanogenmod account in settings but on the website it's OK.
[Samsung Galaxy Core.] ItsMeShouko:
I guess Cynogenmod account service is now dead...
[Samsung Galaxy Core.] doesntexits:
Well, AOSP sucks. After building the ROM you'll find nowhere the file manager :p

Also, vanilla UI not always be the best. If you've used it for a long time, you'll only know black and white color, just like Nokia 1280 :D. Knowing that, CM has included Theme Engine in its source, which is nice

Why there is no radio app in this rom... Is there a way to install it(the one which works)?
[Samsung Galaxy Core.] killerdoor:

i have installed it 3 or 4 times and its heppening the same my device is sm-g355m other time was the keyboard my device its single sim model

[Samsung Galaxy Core.] doesntexits:
Don't ask for FM app on any custom ROMs. It's not supported by the ROM vendor
[Samsung Galaxy Core.] ItsMeShouko:
There was FM radio on stock rom... Also I've seen radio app on many cm custom roms...
[Samsung Galaxy Core.] doesntexits:
FM can be ported by devs, if they want to implement it. IDK why people these days still using FM while we're having internet and TVs :D
[Samsung Galaxy Core.] limjh16:
AOSP has layers by bitsyko and IMO it's way better as you can control which apps get themed individually.

Also, there's no stock file manager from my experience, install explorer from play store or install the ported apk of cyanogen file manager which works perfectly.
[Samsung Galaxy Core.] ItsMeShouko:
One word... Bandwidth...

---------- Post added at 06:20 AM ---------- Previous post was at 06:19 AM ----------

Also I found that there no way to video call someone using 3G network... We have to rely on 3rd party VOIP apps like skype, hangouts, whatsapp etc. I am not saying that native video calling feature is better, but the feature should be present in CM rom as some operators may provide video calling cheaper than internet service.

I'm not sure different code or something...

[Samsung Galaxy Core.] Nexxit99_Gaming:
Why is it difficult to make cm 12 lollipop boot up ?
[Samsung Galaxy Core.] doesntexits:
You know, Lollipop is different than KitKat

Since our stock is already KitKat, and we've the Spreadtrum sources as based in KitKat, so it's easy to make it boot up by patches. Unluckily, Spreadtrum doesn't release Lollipop sources, which is confirmed as "sprdroid5.1" branch btw, but their codes can be modified easily or in the other words: we can "port" the codes to make it usable in Lollipop

Talking about making Lollipop booted, [MENTION=6737662]Ih24n[/MENTION] has got it booted up, but stuck on boot animation, with "adb" disabled or inaccessible, so it's pretty hard to fix that without "adb logcat"

As for stuck on bootanimation, you could try using stock kernel sources and debug from there. If you are already using stock kernel source not a modified CM kernel then I am sorry, I don't know how to help further.

Fine you could have asked nicely OK I won't ask too much ...
