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

Still working on that.

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.

[john_sdr]

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

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

 

[john_sdr]

something about the vpn? or maybe something isnt compatible with cm13?

 

[SpYneX_]

I searched on google and disable the firewall could be a solution.

 

[TimSchumi]

Seems to be a more general problem. I'll look through the device/kernel/vendor trees of similiar devices for a fix.

Could you test it?

How could you even disable a device's firewall?

 

[john_sdr]

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.
