Introduction
This is a UNOFFICIAL build of LineageOS for the Samsung Galaxy Core Plus.
It's not ready yet and has some bugs in it which could cause problems to some users.
The ROM will only work on the SM-G350 Version of the Phone (without any Numbers/Letters behind).

This ROM could be used for daily use now (though you should look at the list of what doesn't work first).

Known Bugs
  • Camera sometimes switches to green-purple. The resulting picture doesn't have the weird color, but it may be flipped and/or distorted at the edges.
  • Video Recording
  • Codecs (some work, some don't. I tested MP4 and AVI, both work. I should really make a list...)

Installation Instructions

Special thanks to @Giovix92 for making this tutorial!

Requirements:
1: A computer with Windows.
2: An Internet connection.
3: A backup of your phone data (contacts, photo, music, videos, and other).
4: About 300 MB free space on your SD card.
5: Phone charged at least 80%.

Download links are below

I do NOT take any responsibility for bricked devices!

Let's start!

1: Download the Samsung USB Drivers.
2: Download the ODIN3. (Only for Windows)
3: Download the TWRP Odin package to your desktop and download the LineageOS 13 zip to your SD card.
4: Make a backup of your files, because the storage will be wiped. (External SD card will not be wiped)
5: Reboot your phone in to the Download mode (Volume Down- , Home- and Power button). Press the Volume Up button when asked. Then open the ODIN3 and connect your phone to your PC.
6: Press AP and choose the TWRP Odin package (recovery.tar) and make sure re-partition is NOT ticked. "Auto-Reboot" should not be ticked either, otherwise you will need to be quick to boot into the recovery immediately after flashing.
7: Press start! Wait a few seconds. Then your phone will be rebooted. Now you can disconnect the cable and power off your phone.
8: Boot your phone in to the TWRP Recovery (Volume Up-, Home- and Power button).
9: Go to Wipe, and Swipe to Factory Reset.
10. After wiping go to the home screen by pressing the home button.
11: Go to Install. Choose the "external_sd" from the top bar. (It says "Storage: Internal Storage (xxxxMB)" by default)
12: Choose the LineageOS 13 ZIP and Swipe to Confirm Flash. Make sure you don't power off while flashing!
13: After the zip has been flashed choose "Reboot System".
14: Wait 5-15 minutes to boot the phone. If the phone keeps booting take out the battery and do a Factory Reset again.
15: When the phone boots the first time, go through the Setup Wizard and you are ready to use your phone!

If there was something you didn't understand, please don't hesitate to ask :)

I just noticed that the sound sometimes "breaks" and sounds like damaged speakers (just for a part of a second, nothing permanent). I don't know if this is a software problem or just my phone. Can someone confirm that? It sometimes happens when doing a call or pressing random numbers at the Dialer. It also seems to happen only with standard sound level or higher.

I'll check it after I fixed (or tried to fix) Internet and SD Card

This is the same on stock when listening YT idk why it happens.
For the sdcard fix check if there are correct mounts for vold.fstab or framework
BTW. Videoplayback isnt working good on YT on Internet browser and is glitched too on chrome.

Thanks for searching :good:
I'll write to developer and ask for the fix!

So, any changes about the network?

Not now, still working on it. I don't even know where to search. :eek:

Well, i just red here "https://forums.oneplus.net/threads/official-cm13-nightly-builds-rolling-out-for-opo.411202/page-103" that its may be fault of the recovery. I dont think that we all got the same twrp though, is something you can test? i used santori's twrp, i had it flashed quite a time. maybe an update or a modification will solve that issue

I knew we need TWRP 3.x.x to install an Android 6.0+ Rom. So, the network issue, could be related to the recovery version.

We should to update the recovery first, to install Marshmallow (and up) on a smartphone

allright, i'll check up for a twrp for our phone :angel:
EDIT: on the official twrp/devices, there is not our device. so, what's up next?

Hey, I'm new here at xda forums. I just installed this ROM on my galaxy core plus, and it works great. My phone is now super snappy. But many features don't work as of now, the bluetooth actually worked for me, I didnt expect it to after reading the post. When will these bugs be fixed, and more importantly how can I follow so that I can get my hands on the new release as soon as it gets out? Thanks a lot!

I also could try to make CM Recovery first, and if it won't work, I'll give TWRP a try.

I still need to search what causes the Internet and SD Card to fail. Bluetooth does work, only Bluetooth Calls, Car connection and other devices are untested.

You can subscribe to this thread or subscribe to the DevDB project, to get a notification if it's updated. To get updates on your Smartphone, you could install XDA Legacy (Tapatalk) or XDA Labs (just called XDA) from Play Store.

CM Recovery didn't fix the problem. And I somehow can't get TWRP to boot.

    Quick Update:

    I now downloaded the CM sources and set up my environment again.

    I'll now try to build up a simple CM/Lineage 14.1 tree to see if this version has the same issues with SD Card and Network
    5
    First Version of CM 13 is up :)
    5
    now that cm is closing, do you have any intention to continue porting android 6 to SM-G350 ? maybe using the linage os name? Is it possibile to know any milestone of your work?

    Of course.

    But CM13 will take a long time to be rebranded to LineageOS. So I will use the CyanogenMod sources until they are finished with rebranding CM13. But I will pull Lineage 13 Sources today and see how far they have gotten with rebranding

    About the milestones:
    I uploaded this project when I thought that it was pretty stable for a beta version. The only things that are still missing since the first release are the Network and the SD Card. There was nothing else I noticed which was not working (except for the Keyboard crashing when using Swipe2Type or however it is called)

    After I'm done with CM13 and TWRP, I'll probably continue with CM/LAOS 14.1 or a newer version
    5
    Ok, new build is up. See the first post for the download link

    EDIT4: We also created a Telegram group so that you can discuss things, search for help and get new information on the most efficient way.
    https://t.me/joinchat/AAAAAEAVRTbRdCBnRbN9Xg

    EDIT: RIL seems to take a long time when booting and it shows 'No Network' for about 20 seconds. Just wait for it

    EDIT2: @QGM
    It now really seems like it got slower. The first 'official' build was a lot smoother. I wonder why this now isn't as smooth as the old build anymore. But it still runs better than CM 11 in my opinion (Concerning smoothness of the UI)

    EDIT3: For all of you who want technical information about the problem:
    It was indeed a kernel incompatibility. I now took some commits on /net from logan and kylevess and now it works (See the squashed commit in the kernel source forbmore information on what changed).
    Many thanks to @sandpox, @zim555, @androidlover5842 and everyone who has worked with Samsung's hawaii-boards
