[BETA] [7.1.2] [j2lte] [UNOFFICIAL] Lineage OS 14.1 [Exynos 3475]

Search This thread
Last update (the one released in January 22) was reverted due to issues with audio in calls.
If you updated to it you may want to go back to the previous version if you want to make calls without any issues.

If you don't need/want to make and receive calls, you can still get the version released in January 22 here:
mega.nz/file/V8Z1WYja#Bi6Gnk5BKTWFMfngiCwWeXmV-O_Ni1IfDFGvLypFHV4
(remember that you don't have to flash the boot image with fixes in this version)

Works pretty fine! I just started these days to understand on how a boot on a cellphone works. I have the SM-J200M and I am facing some problems with battery charging, I left it for hours and it only reached 68% – is this because I didn't installed boot.img? If so, how do I install it? Also, I had to install the ROM twice because in the first time it came with the basic google apps (which I am trying to get rid of).

Edit: Managed to install boot.img on TWRP. But my phone now is stuck at 73%, it is slowly charging, any idea of what can it be, maybe it's my battery?
Edit2: Working normally now!

Thanks.

Yes, to fix the charging issue you need to install the boot.img provided in the thread.
The ROM doesn't come with preinstalled GApps so you must have installed them
 
You probably downloaded the update released this year which introduced an issue with audio in calls.
As i mentioned earlier, the download link in the thread has been reverted to the 2020 version, so download that one.
Hello, i am tried to install the rom from thread which is from 2020 year, but phone call problems are not fixed in it. I also tried to install that one from 2021 jan. its also with that problems. Can you help me in this call problems?
 
Calls are partially working but is not for day by day user (it seems the audio works only 5 secs and noting Mic not working) to get audio working you need to spam the speaker button

Messages app is not working correctly if you send a message the app gives a error sending but the message is sent...

i will edit this post if I find more bugs I'm using the Jan 2021 release

    New update available for download. Sorry for the delay, i had planned to release this update on February, but lots of things happened.
    My Galaxy J2 got a short circuit so i won't be able to actively work on this anymore.

    Changelog:
    • Switched to stock Audio HAL. Fixes audio stops working and some microphone issues
    • Some OMX fixes, which fixed camera video recording
    • Switched to stock power profile
    • Switched to stock sensors library
    • Removed DOZE (Ambient Display)

    Workaround to connect to LTE (4G) networks (thanks to @cıyanogen):
    • Enable mobile data, 3G and reboot. Carrier is now available.
    • Enable LTE and reboot. The device will boot with 3G, and LTE connection should be available in around 10 seconds.
    • If you reboot or turn off the device, the carrier is not available. Enable 3G in settings and reboot.

    New update available. The apps crash problem is now fixed and the Android Security Patch was updated to October 5, 2019.

    I wanted to release this update yesterday, but i wasn't able to do it because my Ubuntu installation almost broke when i was upgrading to the latest version. Luckily, i managed to restore it.
