Code:
/*
* Your (probably expired) warranty is now void.
*
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
*/

Graphics
Camera (photos only)

* Note: an installation since build #3 require you to use sdcard repartition layout, as the ROM is too huge to fit on non-reparted /system partition.
After a clean installation, 702M of space is occupied on /system partition.
Also note that only clean installation is possible if you are upgrading from previous builds.
For the repartition refer to CWM ReParted topic.
Installation order:
flash ROM
flash kernel (kernel is located in the same folder as ROM)

Telephony: squash-reset to 7.1.2 **
* Note: an installation now will require you to use sdcard repartition layout, as the ROM is too huge to fit on non-reparted /system partition.
After a clean installation, 702M of space is occupied on /system partition.
Also note that only clean installation is possible if you are upgrading from previous builds.
** this fixed RIL, but I would consider this rather as a huge hack, it definitely will need to be revised in the future.
All of the telephony code currently is built from 7.1.2 sources, so consider this build still as a heavily experimental.
I haven't tested RIL that much, all I can say so far is that the SIM is being detected, the signal strength is showed and USSD commands works. Everything else wasn't yet tested.
5.10.2017 - build #2
fixed USB
fixed WiFi (credits to @rINanDO)
fixed camera (photos only)
RIL fixes (works partly*)
* receiving SMS and incoming calls seems to be working, however anything else (including answering an incoming call) still doesn't work.

For flashing use TWRP recovery from chrono kernel builds.

I'm not sure if it works in this rom:
Go to Settings, click on "About phone" and then tap seven times (it may vary) on the "Build number".

but it did work on my phone, I remember it's 7 times
But I have another problem, when I want to go back to Los 14.1, I stuck in TWRP logo and I can't get in. Is there any solution to flash back instead of use Odin to flash stock 2.3.6?

There is no root included in this build. You can install a third-party root, but I didn't look into that deeply - there are much of other stuff work on. As stated in OP, this build is a way early, mainly purposed for developers and those who want to help with this project.

Will the S3 mini get this ROM too? I mean, they have the same hardware. Great work!

Despite of having the same (almost) hardware there are difficulties with testing builds on a device you don't own. If anyone on s3 mini forum is interested to work on Oreo bringup, the sources are always available on my github.

@ChronoMonochrome Good progress here!
Btw, could you tell me how you made RIL work?
Here it seemed to be crashed at rild ( https://pastebin.com/NMSbwrET if you need full log )
Code:
RILClient: Connect_RILD: Connecting failed. Connection refused(111)
10-26 16:53:27.189 558 641 E RILJ : Couldn't find 'rild' socket after 8 times, continuing to retry silently [SUB0]
10-26 16:53:27.204 558 649 E RILJ : Couldn't find 'rild1' socket after 8 times, continuing to retry silently [SUB1]

Nothing special here.
Check these patches out: https://review.lineageos.org/#/q/st...branch:lineage-15.0+topic:samsung-libril-oreo
Just for a clarification, I wasn't touching java part of RIL at all - until I find a better idea about that. So RIL is not fully-functional yet.
