LineageOS is a free, community built, aftermarket firmware distribution of Android 7 (Nougat), which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review.

Conserved post.

1) bean gapps are reported to not work properly.
2) Read the below posts for information about opengapps flashing.

3) How to fix YouTube :
3) YouTube fixed. No youtube problem in latest build now.

======================================
F.A.Q :
======================================

Q) Does this ROM support substratum?
A) Yes! The latest LOMS ( LOS with OMS) is fully compatible with substratum and OMS commits have been integrated into the ROM. Since substratum uses OMS, all the themes that need OMS will work on the LOMS build.


Q) Do older builds (non-LOMS) support substratum?
A) Yes. And no too. Some of the themes that need OMS commits won't work. However, the themes which have no OMS commit requirements, will work nicely in Legacy mode. Legacy mode gives you the ability to use some substratum themes, but you will need to reboot after applying any/each overlay to see effect. Hey! It's still better than no theme right?

Q) The ROM is stable enough. Why isn't it official?
A) Many reasons to answer this one lol.
1) @Rohan Taneja (OP) isn't very active with development now. He's busy with higher studies.

2) Compiling ROMs is a very tedious task. Not making it official gives us the freedom to make the builds whenever we want. In official, you have to maintain the builds and make one for the device whenever a new major/monthly update is introduced.

3) Our device. It is a MTK phone. MTK device is happily accepted as official device by almost no rom community.

4) Our choice. Deal with it.
(Please note it isn't just as easy as typing the word "official" in the thread title and build prop to make it official. Noobs please don't spam thread about this topic)


Q) (You think something else can be added here?)
A) (PM me ASAP to tell your suggestion. I'm open to PM's. And please don't send stupid PM's asking to accept friend requests and s-h-i-t like that)

(FAQ section is under construction. Check later for more)

EDIT : Stick to beangapps till the time, I figure out a proper solution.

It is due to some build.prop glitch. I have attached a fix. After flashing ROM, flash this Patch file and then flash opengapps

Video from the camera slows down, the sound behind the video
The mx player also plays with the brakes in hw +
I flash
Flash-memory file Lineage-14.1_buildprop
Later
Gaups okey
(But got a brick, a constant splash screen is not loaded further)
The curved arc is always constantly

I have tested it on RR-N and made same changes for LineageOS-14.1. I had assumed it might, sorry if that is the case.

Flash Beangapps, if Opengapps are causing an issue

No need to flash the patch. I will make changes for future builds

beansgapps not working tested it earlier
what I did to have gapps is flash build.prop fix, flash opengapps, flash default build.prop

Yes it's another workaround for gapps, but it is just dirty hack for such an issue.
Declaring device architect as arm64 crashing the ROM is really weird part of the problem. It's only happening to LineageOS and based ROMs like ResurrectionRemix for our device.

Need to debug the build thoroughly for now.

 

[anaandshailu]

Will it be official in future?

 

[Abhignu]

Jio works in this rom ?

 

[Rohan Taneja]

Will it be official in future?

LineageOS team would never support MTK in the meantime, even their project on Wileyfox's Spark has been officially discontinued.

Don't expect it to be official in near future

OFFICIAL is just a tag. Real Deal is the firmware, it should be good enough for daily users.

Jio works in this rom ?

Yes, tested myself

Hello! Can u add pls Engineer Mode to edit audio and mic values? Or it's not possible in android 7 on MTK chip's?
If this possible, add same pls in AospExtended ROM V4.2

Dude, engineering mode usually always exists in all ROMs. You can try to activate it using the dialer code... Google the code yourself. Don't be always dependent on us for links and stuff.

I'm not a noob, i know that code *#*#3646633#*#*, try to insert them in [ROM] [7.1.2_r8] [OFFICIAL] [aio_row] AospExtended ROM V4.2 [OMS/DUI], and see "This rom seems to be dont have engineer mode".
That's why i'm writing that ****.

If you dont use engineer mode - i'm using it, rom which without that - not usable for me because i can't insert my volume and mic values. that because i'm asking about it.
