General:
CyanogenMod 11 for Samsung Galaxy Trend 2. (SM-G313HN) This is not 100% completed, so bugs can be expected. There are some bugs listed on this post and if you find more, report them to me. (Either to this thread or via private messages) It will help alot to fix them.

Note: Google apps are not included. Get them here. I recommend using Mini or smaller, because when installing a OTA update, the bigger packages don't fit on RAM if the internal storage is full. You can install the rest from Play store. It is also kinda pointless to have for example, Youtube and Google Maps on /system, because when they are updated, the updated versions go to /data anyway.

Screenshots:


Downloads:
* Latest build
* All builds

Installation:
* Install a custom recovery. (Get CWM here)
* Download the latest version to your SD-card.
* Boot into the recovery mode by pressing <Vol. Up> + <Home> + <Power>
* You can navigate on the recovery mode with the volume keys. <Power> opens the selection and <Back> goes to the previous menu.
* Backup your stock ROM by going to the SD card by going to "backup and restore" -> "backup to /storage/extSdCard". You need about 3-4 gigabytes of free space on the card, depending how full your internal storage is. You can go back to stock if you don't like this ROM, by going to "backup and restore" -> "restore from /storage/extSdCard".
* You need to do a factory reset before installing this. You can do this by selecting "wipe data/factory reset". The installation won't let you install the ROM without doing this.
* Select "install zip" -> "install from /storage/extSdCard" and then select the zip you downloaded.
* Optionally install the OpenGApps-package while you are in the recovery the same way. (Doesn't need a data wipe)
* When it is done installing, go back to the main menu and select "reboot system now" and that should be pretty much it. The first startup takes a while.

Updating:
CyanogenMod checks for updates weekly by default. You can update the phone manually by going to Settings -> About phone -> CyanogenMod-updates, tapping the refresh button and selecting the latest one. After it is downloaded, you can install it.

What works?
* Audio
* Bluetooth (At least file transfer between 2 devices is confirmed, no other devices tested. (For example. headsets, keyboards, etc.)
* Calls
* Camera
* Data connection
* DSP Manager
* GPS
* NFC
* Offline-charging
* OTA updates
* Text messages
* USB (Adb, MTP, PTP, UMS, Tethering, etc)
* Video playback/recording (Mostly.. Front camera video recording doesn't work and some codecs don't work.)
* WiFi
* Wired headsets (Audio, microphone, button)

Bugs:
* First startup might is laggy. The best way is to just skip everything, change the language and set up the accounts, etc. from the Settings app.
* Some videos don't play, because there are some codec issues. (For example on Facebook. YouTube seems to work fine.)
* Some have reported about higher battery drain when using WiFi compared to stock ROM.
* Reported that when calling or sending messages, the phone causes more interference to TV/radio signals than stock. (Excessive transmitting power?) Not too noticeable unless you are very close to the antenna, so it shouldn't cause too much problems. Possibly uses more battery.
* When USB debugging enabled and the phone is restarted, turning USB tethering on too quickly doesn't turn it on completely and removing the USB cable the phone causes the phone to freeze. (This happens when using Linux, the computer shows that it is trying to connect to the internet but the phone shows that USB tethering is not enabled) When this happens, it can be fixed (When the cable is not removed) by going to the settings -> developer settings and disabling ADB, then re-enabling it and finally then turning on USB tethering. Yes, Linux + ADB + turning on USB tethering within 10-20 seconds after rebooting. I know this doesn't affect many people, but happens to me frequently.
* Front camera video recording doesn't work.

Thanks a lot!

Best wishes with very first custom rom for Trend 2! Keep going!
I prefer pico or nano GApp build. This one should works on CM-11.

update:
I've found that this is very stable and fast ROM, not bugged as I had experience with CM11 on Huawei.
It even works with microG (GApp replacement) very nice! I only use Play Store and YouTube app.
New Pipe (Youtube replacement) have problem only for WebM format video is blue/pink filtered, but smooth playing. For MPEG-4 format, play normal.
Samsung S6 CM11 theme and S Launcher 6 made Trend 2 looks similar to stock touchwiz environment

 

[Edwin Hamal]

I found more bugs. Bluetooth isn't working and device forgets wifi password with every reboot.

 

[Nikiz]

New build coming soon! Changes:
- Most of the hardware codecs work now. (Tested: video recording/playback, Youtube, DSP Manager)
- When I updated the CM sources, there was "Android security patch level" in "About phone". Not sure if these will update automatically or what.
EDIT: New build is available!
EDIT2: Fixed the "WiFi amnesia". Quick patch: https://www.androidfilehost.com/?fid=24269982086999294.
EDIT3: New build uploaded. Fixed the WiFi bug and the offline charger now works.
EDIT4: Accidentally uploaded the eng-build. (Red flashes around the screen and insecure ADB) >.< Rebuilding..
EDIT5: Re-uploaded the build.

Small teaser:

Small teaser:

G313HN got CM12.1 now )
G313HU got CM11 )
and now G313HZ is the worst of all (

Most of all: G313HZ use Spreadtrum chip instead of Broadcom

 

[adeii]

G313HN got CM12.1 now )
G313HU got CM11 )
and now G313HZ is the worst of all (

Well, er, it is CM12.0 for G313HN
And Galaxy V (G313HZ) got whole thread with CM11.0 also.

 

[doesntexits]

But it has lots of bugs

 

[Nikiz]

Well, the CM12.0 is not usable yet. The base system works pretty well, but RIL/WiFi/Bluetooth are not working yet. Well, it is the first build that actually boots. Also logcat shows alot errors. It is strange, the RIL and WiFi works for about 30 seconds after the first boot, then suddently stops working.. Also, I found out why the stock /init works and CM one doesn't. ueventd tries to load < 32 characters long ueventd.{hardware}.rc and "ueventd.hawaii_ss_vivaltonfc3g.rc" is too long. It needs to be renamed (or patch the init) "ueventd.hawaii_ss_vivaltonfc3g.r" or sometimes "ueventd.hawaii_ss_vivaltonfc3g". (I have absolutely no idea why it varies..)

Great job anyway.

Btw bluetooth should work if you'll use the stock libs (on cm11).
and thanks for pushing patches .

Thanks. Btw, here are the DS-versions of the patches: https://github.com/ZIM555/android_device_logands/tree/master/patch Just add the external/tinyalsa to it. Btw, could you try to boot HU with HN kernel and show what "cat /proc/cpuinfo" and "cat /proc/simslot_count" shows with it? It might be possible to make one ROM for both devices. Just need to change "ro.telephony.ril" on init. I just need a way to detect which device it is regardless of what kernel/ROM it is running.
EDIT: Well, I need to figure out a way to disable NFC, preferably without deleting files.

Ok, i'll check it out.

 

[Nikiz]

Well, the Cyanogenmod Updater is not working.. The OTA server seems to be working though.
EDIT: Oh, it works. Had to add "/api" to the url.

What server do you use btw? xdarklight's one?

 

[Nikiz]

What server do you use btw? xdarklight's one?

I use this: https://github.com/julianxhokaxhiu/CyanogenModOTA It is simple and easy to set up. Doesn't require mysql-databases, etc. Just download it and boom, it works. Or at least should work. I had to do some small modifications to it.

 

[Nikiz]

Btw bluetooth should work if you'll use the stock libs (on cm11).

Got Bluetooth working on CM libs! Well, atleast file transfer works between two devices. I have no headsets to test though. Just add bt_vendor.conf to /system/etc/bluetooth-

# UART device port where Bluetooth controller is attached
UartPort = /dev/ttyS0

# Firmware patch file location
FwPatchFilePath=/system/vendor/firmware/

#Firmware Patchfile name
FwPatchFileName=BCM4343A0_001.001.034.0044.0127_ORC_Vivalto-3G_5MC.hcd

(SM-G313HU seems to use a newer patch file, just rename it)

Also made some changes regarding NFC, but I have no way to test it.

The OTA server seems to just dump all builds, regardless of what version is in use so the phone will show older builds as updates as well..

 

[Nikiz]

New build! Changes:
* Bluetooth is now working. (At least file stransfer)
* Small changes to NFC, might not work though. I have no way to test this.
* Uses now the Cyanogenmod /init, no longer using the stock one.
* OTA updates enabled!

 

[itigr]

Great. One more question, does your kernel compile while building CM? I can only compile it by going to kernel dir and running make here, then defining TARGET_KERNEL_PREBUILT, eitherway it ****s about "zconf.hash.c" .


UPD0: Just started compiling and sata connection died -_-, dammit.

UPD1: one guy reported couple months ago that headset (bluetooth or wired, no idea) button doesn't work

I am compiling the kernel while building CM. It just works for me. I use ArchLinux. Try to use my kernel sources. One thing though, the build might fail, because the new glib. Use "export LANG=C" before building, or add it to "~/.bashrc". For some reason linking libwebviewchromium.so takes for me about 12-48 hours when I reinstalled Arch, normally it took about 6 hours for the whole build..

I just tested the wired headset with the "Okay Google"-thingamajig and it is working perfectly.
